\"\"Hello and welcome to our first bigger Review! Today we want
\nto show you some battery packs and what you can expect
\nfrom them. Nowadays where our mobile companions need
\na lot of power, battery packs come in handy.<\/p>\n

Introduction<\/h2>\n

We all know it: We use our cell phone to capture moments, videos or just some quick research online and just as it ever so happens: the Battery is about to die.<\/p>\n

For this case we have our battery packs that provide some extra juice so we can continue our online journey or whatever we just do with our mobile devices.<\/p>\n

Our review will cover a wide range of batteries: Small ones which provide approx one third of the iPhone 7 battery capacity (1100 mAh) up to a whopping 10-times-charge (30000mAh)!<\/p>\n

So anyway, what is a general recommendation for a battery pack? – Simple answer: There is none! First of all you have to ask for yourself: “What do I want to charge and how much autonomy do I need.<\/p>\n

If you have the answer, then you’ll figure out also which battery pack you want to purchase. Keep in mind that good battery packs also have their price. For god’s sake and the health of you and your devices, don’t buy these cheap battery packs that promise 100.000mAh, 300.000mAh and even 500.000mAh capacity for just 20 dollars at the size of a battery pack that only provides one twentieth of the capacity. Most likely they do not provide the announced capacity and you also run risk of the cheap batteries inside to catch fire and that’s something we don’t want at all!<\/p>\n

Oh and one more thing: If you plan to fly make sure the battery pack is stowed away in your hand luggage as it may not be placed in your regular luggage due to safety regulations. There’s also a limit on capacity: The battery pack may not be larger than 100Wh capacity (100.000mWh). Some airlines even limit these packs down to 50Wh (50.000mWh). Ask at the check-In counter for their safety regulations and have them confirmed for your return flight as well! Especially for flights to the USA: Make sure your battery pack is fully charged so that border customs see that it isn’t a possibly dangerous device for flying! You don’t want your expensive gadget to be disposed at the security check for the sole reason of a discharged battery! This also applies for your electronic devices such as tablets, music players, cell phones and the like!<\/p>\n

The test is done with an iPhone 7 Plus, which has a battery size of 2840mAh. Before the charging process is started, the battery is drained to 10%. The “Charged-at” value is what you’ll see when the battery is all empty and the iPhone is stopping the charge process. The QI charge process is done with an iPhone X as it has similar capacity to the iPhone 7 Plus so the values are better comparable to each other<\/p>\n

LiPo or LiIon, that’s the question…<\/h3>\n

While LiIon (Lithium-Ion) appears to be the more solid technology, the problem is that the charging technology needs to be very safe in order not to let the cells (mostly 18650 type) burst or take damage. LiPo (Lithium Polymer) is a bit easier to manage and the fact that you can form almost every shape with the polymer foil makes it first choice for battery packs that need to have a certain shape, thickness or the like.<\/p>\n

The case holding the cells can be filled efficiently unlike it’s LiIon brothers whose limitation is the round cells inside. They result in gaps between case and cells.<\/p>\n

The only reason why LiIon is still so frequently used is the optimal combination and alignment of the cells to produce a certain voltage. Each cell has 3.7V and thus you can build up any multiple of this voltage by putting 2,3,4… of them together in an array. With LiPo you can also build up any multiple of 3.7V but if one cell is smaller than the other one, then the smaller cell may suffer from faster weardown and thus the batterypack may loose capacity by time.<\/p>\n

A Question of freshness<\/h3>\n

Some people complain about fresh battery packs not supplying the announced capacity…<\/p>\n

That’s a normal process as a battery pack gains it’s full capacity when being fully discharged and charged three times. After that, the battery pack should be near announced capacity.<\/p>\n

So if you think your freshly purchased battery pack doesn’t deliver what it’s package promises, make sure your battery pack has been “initialized” as mentioned above.<\/p>\n

A word about storage<\/h3>\n

Keep in mind that the cooler or hotter a battery pack is stored or operated, the degeneration process may accelerate and thus end up in less capacity provided or worse, malfunctions.<\/p>\n

If you need to store a battery pack for whatever reason, make sure that the cells are charged up to 90% and keep it in a cool place (15-25 Degrees) with a relative humidity of 35-80%.<\/p>\n

This way your battery pack can survive an annual storage with ease. Make sure to check the charge level after 6 monts or so to avoid complete dischargement of the cells. That’s every rechargeable battery’s death, especially LiPo or LiIon batteries may die quickly.<\/p>\n

A word about safety<\/h3>\n

LiPo and LiIon batteries are sensitive devices. Short-circuit, Overloading, Overheating, puncturing or other heavy physical use of these may end up bad for you. The worst case might be that the battery inside may catch fire and do much more damage to your goods or to yourself if you carry the battery pack on you. So make sure the battery pack isn’t exposed to any such bad environmental impact. Also keep in mind that extinguishing a burning liPo or LiIon battery with water is a very bad idea as Lithium is highly reactive with water. Should the rare case come true and your battery pack catches fire, try to extinguish the fire with a fireproof cloth or sand. Also a fire extinguisher that is made for electronic devices may suit you well but for heaven’s sake, never try to extinguish the fire with water!<\/p>\n

Skross Emergency Battery – 1100mAh<\/h3>\n

The first battery is from the swiss manufacturer “Skross” and definitely the smallest power source when it comes to emergency charging. Thus it’s capacity isn’t very big, namely only 1100mAh, which would theoretically give an iPhone about 1\/3 of it’s juice back.<\/p>\n

Since it is rather small, the name is program and you’d better have a larger battery packed if you plan to be on tour for a longer time. This little battery is really only for\u00a0 “Emergency” charging.<\/p>\n

The haptics are okay, the case is made all plastic<\/p>\n

4 LEDs show you the actual charge level and with the press of the power button, you can start the charge process.<\/p>\n

With it’s “retractable” USB connector, this mini battery pack nearly fits ever so tiny pocket.<\/p>\n\n\n\n\n\n\n\n\n\n

Philips Batterypack – 1800mAh<\/h3>\n

This battery pack is from Philips and is now about 5 years old, yet delivers OK performance for what you got 5 years ago for your money. Although this pack isn’t that big, the capacity looks promising.<\/p>\n

The haptics are okay. Although Plastic dominates the whole case, the feeling that it isn’t all hollow inside makes it all worth.<\/p>\n

It’s the only powerbank so far I’ve seen that has a Mini-USB port to have it charged.<\/p>\n

Alongside there’s a power supply that delivers 5V\/500mA with an USB-B port to connect the battery pack. And alongside you get a set of plugs to charge various older cell phone models. Was handy in the past but with the Upcoming of Micro-USB this sort of gets obsolete.<\/p>\n

If the batterypack appears to be non-charging or delivering way less capacity, there’s a reset pinhole to reset the charge logic and hopefully regaining the capacity announced. Had to use this feature twice so far but works well.<\/p>\n\n\n\n\n\n\n\n\n\n

Pearl Battery Pack – 2200mAh<\/h3>\n

The next battery pack was a gift from online Reseller Pearl. Similar products we found were at roughly 10 CHF so our expectations were not too high at all. But let’s have a look at the values that little battery has produced.<\/p>\n

As you can see, the battery does only deliver 90% of it’s designed capacity. It’s casing is held basic. Transparent tube around the inner case and two USB ports on top, micro-USB for charging, USB for discharging. Most likely there’s a single 18650 LiIon-battery inside…
\nThe lack of status LED or a key to test capacity can nhowever put you into challenge as you don’t know when this battery is out of juice. So you better charge it just before you leave the house.<\/p>\n\n\n\n\n\n\n\n\n\n

reVolt SolarBank – 3500mAh<\/h3>\n

The next battery pack is a bit special. As the name suggests, this battery pack comes with a solar panel allwoing it to be recharged using sunlight.<\/p>\n

Although we personally think exposing a battery to direct sunlight (and the resulting heat!) is no good idea, the concept as such is ingenious. Without the need of a wall outlet you can recharge the battery pack with the help of mother nature. However recharing the battery pack with sunlight is very time-consuming. we didn’t test it but the manufacturer says it takes up to 20 hours of sunlight to have this battery pack at 100 percent again.<\/p>\n

As you can see, the battery does only deliver 59% of it’s designed capacity. It’s casing is held basic with a soft touch skin. Two USB-B ports on top, micro-USB for charging. Basic stuff yet remarkable that this low-capacity offers two USB-B ports for simultaneous charging. Their combined output is 2.1A, so either it’s 1 Port with full power or both ports with 1A each!<\/p>\n

The four LED indicator tells you how much power you have left and a red LED on the backside (where the solar panel resides) tells you if the batterypack is being solar-charged.<\/p>\n\n\n\n\n\n\n\n\n\n

ASAP Dash – 5000mAh<\/h3>\n

The ASAP DASH is also a rather spechial battery pack. Designed by ASAP, a company that specializes in modular charge cables (with magnetic tips), it also offers QuickCharge with 19V. One might think, it comes in handy but if you’re on the road, and no wall outlet is nearby then you can’t use that feature. Plus you have to take an additional power supply with you being capable to deliver the 19V\/3.0A output, suggesting a 60W power output.<\/p>\n

So how does it compare to the other battery packs?<\/p>\n

Well at first, there’s nothing special to it. You get a standard micro USB cable along with the usual stuff and a power supply to quickcharge this batterypack<\/p>\n

One USB-B connector that delivers up to 2.4A should be sufficient for must USB devices even tablet computers.<\/p>\n\n\n\n\n\n\n\n\n\n

Xtorm AL370 – 7300mAh<\/h3>\n

Okay, let’s have a peek on our next contestant. The brand Xtorm is well-kown in Europe and their mobile chargers offer good performance for a good price tag. While most other chargers in that price range either suffer from connectivity or from variety, Xtorm offers various types of mobile chargers for almost every occasion. So you can choose from portable\/lightweight chargers to ruggedized heavy-duty chargers or even notebook chargers (one will be tested later on!)<\/p>\n

The casing mostly gives worthy touch with it’s brushed metal or at least is what you would expect for what you pay for!The backside has good touch with it’s soft touch surface and allows for better grip.<\/p>\n

What we like is the fact that it comes with a built-in charge cord (USB-B) that snuggly fits into the case. So you don’t have to worry about an extra charging cable for the battery pack. And the second cable alongside the case is micro-USB to charge all devices that support charging via micro-USB! Clever engineering!<\/p>\n\n\n\n\n\n\n\n\n\n\n

FDGAO QI Battery pack – 10’000mAh<\/h3>\n

Let’s have a peek on a special contestant here. So far, you’ve seen normal battery packs that all require you to have your charge cable with you in order to charge your mobile device. As QI wireless charging gets more popular with more devices supporting it (breakthrough for a standard was given when Apple finally joined the QI standard), the demand for such technology also rises!<\/p>\n

So what we’re looking at, is a battery pack that not only offers 2 USB ports for conventional charging but also a QI coil at the top of the housing to drop your QI-capable device on it. Although the charging power is limited to 1A as it is no High.Power coil, the delivered 5W are sufficient to charge also modern smartphones, like the iPhone X or Samsung’s S8 for an example.<\/p>\n

With a whopping 10’000mAh capacity at a rather small size, the question is: “May it deliver what it promises?” – That’s what we’re going to find out now. Especially the price tag of only 12 to 16 CHF might let you raise your eyebrows.<\/p>\n

Okay, the haptics may feel cheap as the leather imitation is actually moded plastic but hey, you can’t ask for a gold bar and only pay the price of a pebble. The design however looks nice and gives it a modern look.<\/p>\n

The downside is that the input port seems not to take more than 1A charging power, making recharging of this battery pack a patience challenge. So better plug that buddy in before you go to bed and let it charge overnight.<\/p>\n

The mobile battery pack can be ordered either via Wish but if you search for the brand (FDGAO) you will be able to find it in Stores selling on Amazon Marketplace and other distribution channels, at higher prices, naturally! So if you’re willing to take the risk, go for it via Wish and order it directly from the supplier (which is located, surprise! surprise!, in Shenzhen, China). Wish has however a good customer protection service so it is no total risk but as you know customs might hold back deliveries if they obviously violate local safety regulations.<\/p>\n

We personally like the bright LED percentage display and the “breathing” QI symbol when charging wirelessly. It’s quite an eyecatcher!<\/p>\n\n\n\n\n\n\n\n\n\n\n

Xtorm PowerBank AL011 – 11’000mAh<\/h3>\n

Welcome to the next contestant that enters the heavyweight class. Okay, as you might have noticed, this review follows a simple line: From lightweight to heavyweight (from smallest capacity to biggest capacity).<\/p>\n

So what we look at here is a true power monster when it comes to charging multiple devices at a time. Not only are there 2 USB ports which sum up to 3.1A combined output power but it also comes in a sort of iMac style. However don’t let spashes hit the case as it is for sure not water resistant. And as we all know, LiIon batteries don’t like short-circuitry at all!<\/p>\n

The high-gloss cover is nice to look at but attracts fingrprints as hell and also dust will be visible soon.<\/p>\n\n\n\n\n\n\n\n\n\n\n

ASolar <\/strong>Xtorm PowerBank AL380 – 14’000mAh<\/h3>\n

Next one please: the ASolar Xtorm Powerbank AL380. With 14’000mAh this battery pack is suitable for looooong travels. Although it has a large capacity, the charging power is 1A per port, so tablet users may be patient and should not use the tablet during charge process.<\/p>\n

What we have here, is a true power monster for cell phone owners that are outside for a prolonged time! Large capacity but low-Power ports make it a companion for cell phone users as tablet computer users won’t be too happy with the results.<\/p>\n

A built-in LED torchligt (being bright!) makes finding the connector to the cell phone easier in the dark. But the torch is due to it’s brightnes not limited to connector-finding.<\/p>\n

The design is sleek and non-spectacuar and reminds me of a typical Apple product with it’s glossy surface but smudges and fingerprints are magically attached to it and you’ll find yourself carrying a microfibre cloth with you!<\/p>\n

Average power measurements are not what a pro user is looking for but it might help filling up your phone<\/p>\n\n\n\n\n\n\n\n\n\n\n

ASolar <\/strong>Xtorm PowerBank XB102 – 15’000mAh<\/h3>\n

On to the next behemoth of power banks. with 15’000mAh this battery pack has enough capacity to even fill up your tablet computer.<\/p>\n

So what we look at here is a true power monster when it comes to charging multiple devices at a time. Not only are there 3 USB ports which sum up to 3A combined output power (which means, 1 device at 2.4A, 2 devices at 1.5A each, 3 Devices at 1A each) but it also comes in a sort of ruggedized style. However don’t let spashes hit the case as it is for sure not water resistant. And as we all know, LiIon batteries don’t like short-circuitry at all!<\/p>\n

With a built-in charge cord, you don’t have to worry about how to recharge the battery once it has been drained but make sure you have an USB plug with you to attach it to.<\/p>\n

With a whopping 3 output ports that deliver a combined output of 3A(15W) you will be able to have one device charged at 2.4A(10.2W) or 2 devices combined at 1.5A(7.5W) each or 3 devices at 1A(5W) each. So you can say “sharing is caring” and if you’re out with your buddies and one of them needs to juice up his device while you do, you can do so with ease!<\/p>\n\n\n\n\n\n\n\n\n\n\n

Varta<\/strong> Powerpack Type 57962 – 16’000mAh<\/h3>\n

Varta, known as a manufacturer for alkaline batteries also entered the arena of powerpack suppliers. With their powerpack they try to win the sympathy of cell phone and tablet computer users. So how will Varta compete against the others. A successor or big looser?<\/p>\n

The design is nothing special – it does it’s job, no less, no more! Simple case, port description, LED indicators, a LED torch in the form of one bright LED and of course Varta’s logo on it, that’s all you’ll find. Ideal for minimalists!<\/p>\n

The haptics feel a bit cheap due to the plastic case but as long as the Powerbank does what it promises, it’s okay. Another good fact is the low price for the capacity you get.<\/p>\n\n\n\n\n\n\n\n\n\n\n

Aukey PB-Y2<\/strong> Gen2 – 16’000mAh<\/h3>\n

A similar big battery pack is the Aukey PB-Y2! It is newer than Varta’s battery pack and thus offers QuickCharge technology at one of the USB ports which means that any capable device supporting QuickCharge technology, can beef up the Charge speed by 75%. Although the output still doesn’t exceed 2.4A, the manufacturer claims Qualcomm-QuickCharge-compatible android devices to be charged 75% faster than usual devices. As we don’t have any Android devices supporting QuickCharge, we cannot verify this statement nor can we tell how these devices get pumped up so fast.<\/p>\n

Anyhow, testing with iDevices, we get remarkable values and you get what you paid for. A solid battery pack that juices up your cell phone several times.<\/p>\n

EasyAcc PowerBank JP20<\/strong> – 20’000mAh<\/h3>\n

Okay, let’s hit the 20Ah border and have a look at the really big things here.<\/p>\n

EasyAcc is not too well-known here in Europe but they sell BatteryPacks via resellers. The JP20 from them has arrived at our desk and wants to be checked thoroughly.<\/p>\n

Unpacking that beast you clearly notice it’s large dimensions and weight. Stuffing 8 LiIon cells into that case is a challenging task but worked well.<\/p>\n

With 2 USB-B Ports that deliver a 3.4A combined power output max. the power bank may charge a tablet computer and a cell phone at the same time. The specialty is that it also offers a 9V\/1A output for cameras so you can also charge them if your camera runs out of power.<\/p>\n

The sky-blue display itself shows the accurate charge state. However our sample seems to have a problem, charging higher than 97%. At 97% the charging process gets interrupted repeatedly and the display starts flashing. The voltmeter however shows that there’s still power getting in but we doubt it’s anyhing near efficient with the constant switching.<\/p>\n

The soft touch surface allows a good grip which isn’t bad at all with this heavy beast.<\/p>\n

That’s all you can say about this battery pack now.<\/p>\n\n\n\n\n\n\n\n\n\n\n

AData, mostly known for it’s data storage solutions enters the powerbank market. The first product we got from them leaves a good impression and seems to deliver solid value for the buck. Although the similarity to other products is given, this powerbank however is being covered by the Quality assurance of AData. So if there’s a problem with the product, you don’t have to get in touch with an unknown company and haggle with the customer care service 8if existent!) to get a replacement.<\/p>\n

So what do we have here? It’s just basic features. 2 USB B ports offering together 2.1A output power or 2.1A singe port power thus allowing tablet computers to be charged as well. Also a bright LED torch is built-in so you don’t have to search for the ports in complete darkness. The capacity display is backlit in blue so you can read it in complete darkness as well. The display backlight goes off also when charging so that beast may reside on your nightstand for charging. However with a charge time of 33 hours it takes more than a day to have it fully recharged. WTF! Come on, even bigger battery packs can charge a lot faster at same voltage\/power and with bigger capacity. So what’s going wrong here? Maybe the integrated charging logic board is not optimized. However I’ll take further investigation into this and hopefully find out what makes the recharge process so sluggish.<\/p>\n

Also the efficiency is, frankly said, terrible. 40% isn’t something that a battery pack schould end up with. This appears to be a severe design flaw in the charging logic or the logic board itself. Maybe it’s just that the pack has been charged and discharged twice…<\/p>\n\n\n\n\n\n\n\n\n\n\n

Anker Astro E7 Gen2 (A1210)<\/strong> – 25’600mAh<\/h3>\n

On to Anker… Although this brand is rather unknown, they seem to have a good portfolio of power products so time to have a closer look at the Astro E7 Gen2.<\/p>\n

Although this power bank comes with a whopping 483g weight, it is sort of portable. But you certainly don’t want to carry it in your jacket’s pocket. With a total power output of 4A (20W!) this beast can feed two tablet computers or 3 cell phones with ease. The IQ Power technology allows intelligent power distribution. So when you attach 2 cell phones and one tablet computer to it, the tablet computer gets 2A while the cell phones get 1A each. Clevery done and a real deal if you have multiple devices to be charged at once. A single port is however fed with 2A maximum although the output power is designed for 4A. Anyhow. The black glossy is a real magnet for dist and fingerprints which might let the battery pack look smudgy soon if you don’t carry around a microfibre cloth with you.<\/p>\n

The built-in torch is not that bright but serves it’s task. No less, no more.<\/p>\n

4 LED show the current capacity. As they’re tiny, you might have trouble seeing the capacity during the day.<\/p>\n

Aukey PB-Y7 <\/strong>– 30’000mAh<\/h3>\n

The final contestant with the biggest capacity is a real biggie here. So far we haven’t found any bigger battery pack for mobile devices. We speak of a total size of 30Ah which is sufficient to pump up your iPhone approx. 8 times.<\/p>\n

Not only is this powerbank equipped with two USB-B connectors but also with a USB-C connector to supply higher current output. Devices capable of Quick Charge with higher currents (the iPhone 7 \/ iPad Pro Gen1 \/ iPhoneX are such phones btw.) will profit from a much quicker charge process.<\/p>\n

The USB-C port will also detect if it’s used for charging. So it also acts as an input port for the battery pack allowing it to be juiced up much faster than with the conventional MicroUSB port.<\/p>\n

The built-in torch is not that bright but serves it’s task. No less, no more.<\/p>\n

A LED-illuminated power button shows the current capacity. White means: 100-66%, Green means: 66-33%, Red means: 33-0%.<\/p>\n

As we have mentioned in the intro already you might run into trouble having this biggie with you on flights as it exceeds the maximum allowed capacity of 60Wh on some airlines. Other airlines allow 100Wh but you better have a chat with your airline and clarify things before you end up leaving your mobile power gadget at the airport.<\/p>\n

BlackFox PowerBomb 16000<\/a><\/td>\nXtorm AL390<\/a><\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n

\u00a0<\/a><\/p>\n

Okay, now on to the extraordinary battery packs that are designed to charge notebooks.<\/p>\n

The following battery packs are designed for charging notebooks delivering higher voltages but they also provide standard USB ports to charge mobile devices.<\/p>\n

BlackFox Powerbomb <\/strong>– 16’000mAh<\/h3>\n

With this biggie at hand you will be able to give a bit more juice to your notebook. Especially when on tour nothing’s more annoying than a notebook you’re working with and which is about to turn off due to an empty battery. For such situations the BlackFox PowerBomb may come in handy. Not only does it provide an USB-B port for charging mobile devices (but with poor efficiency!) it also offers the ability to charge your notebook at a selectable output voltage of 12, 16 or 19 volts according to what your notebook is closest to.<\/p>\n

About the haptices, one can say that the brushed metal gives it a classy touch but also attracts fingerprints like hell.<\/p>\n

An advantage is that this powerbank is rather slim unlike it’s LiIon-colleagues. So it can be tucked away in even the smallest room in your backpack.<\/p>\n

While USB efficiency is poor, the notebook charging efficiency is really good. Tests with a notebook has shown that the battery of it can be charged roughly with another 30% when not in use. That is in most cases another 1 hour of Outlet-independent working.<\/p>\n

A wide variety of delivered adapters allows you to virtually add juice to any notebook out there in the wild.<\/p>\n

The downside however is that you cannot recharge the PowerBank with plain USB. You will always have to bring it’s power supply with you in order to recharge it.<\/p>\n\n\n\n\n\n\n\n\n\n\n

Xtorm PowerBank AL390<\/strong> – 18’000mAh<\/h3>\n

Another special contestant is the Xtorm PowerBank AL390. Often there’s the joke about having a mobile wall outlet with you. Xtorm however made this joke come real. The rather big battery pack is housing a classic C-Type socket for the so-called Euro plug. Besides that there are also 2 USB ports to add some more juice to your mobile devices if needed.<\/p>\n

What is really astounding, is the extremely good notebook charge efficiency. With a 111% efficiency it’s interesting to see that more power is issued than taken. we did the test multiple times to assure that there’s no measurement error and we ended up with the same results over and over again. we only have one explanation: Either our 230V measurement device to determine the power draw from the outlet is measuring less than real or the AC outlet of the powerbank is producing odd results.<\/p>\n

The haptics of this powerbank, well, the black plastic makes it odd to handle and yells out cheapness.<\/p>\n

Also we noticed that activating the AC outlet brings up coil whining. Seems normal as there’s a transformation from 19V to 230V ongoing. As the AC outlet is fixed to 230V keep in mind not to plug in devices that require 115VAC!<\/p>\n

we noticed a rather worrying heat dissipation next to the power outlet. There’s a fan inside trying to cool down the electronics inside but keep in mind not to have this battery pack exposed to direct sunlight or covered in blankets etc. while in operation as it might overheat!<\/p>\n

Verdict:<\/h3>\n

To make it clear: None of the products were totally bad or totally good, however some products have a very poor efficiency compared to their price\/size.<\/p>\n

Interesting to see that a 16 CHF product from Wish made the first place in this test. The caveat with this product however is that if it breaks then refunding\/warranty claim may become a challenge.<\/p>\n

So you might want to check first if you’re good to go with this product or if you want to have the safety of warranty in case the battery pack ceases function!<\/p>\n

The XTorm AL380 was disappointing as the capacity put in was missed by far. It is the battery pack with the worst efficiency in this test and thus cannot get a big recommendation from us although the product still ranked “average”.<\/p>\n

In the end it’s up to all of you who wants to spend what amount on what product and what your preferences are. Some products have an excellent capacity\/efficiecy factor.<\/p>\n

So maybe this table has given you a good overview on what to choose and what not.<\/p>\n

But dash it all… all these products have their right to exists at any point and luckily all these products are safe to use.
\nNone of the products have shown any sign of blowup (LiPo batteries do that) or did explode and\/r start burning (LiIon batteries tend to do that so a very good security measurement at voltage\/charge monitoring is necessary to maintain the 18650 cells inside!).<\/p>\n

Usually LiIon-batteries are way more expensive as they need a more complex security measurement when they get charged or discarged and\/or short-circuited!<\/p>\n

We haven’t however tested short-circuitry proof of the products as we don’t want to break them or start a fire in our home. But generally it’s no wise idea to short-circuit any battery no matter if it is a small battery or a big battery pack!<\/p>\n

So how did you like that review?<\/p>\n
