Xtorm Wireless Power Bank 10.000 quick review

By Anton D. Nagy April 13, 2015, 3:56 am

Almost two years ago, we started off our Xtorm Power Bank 11,000 quick review by saying that “sadly, battery life is one of the main concerns when it comes to buying a new gadget. Manufacturers are following, to the letter, a trend which makes our phones and tablets thinner and thinner while sacrificing battery life”.

Fast forward to today, and that very same sentence still holds true, more than ever. Devices got even thinner, and battery life, while it didn’t get (much) worse, it didn’t get better either. If you’re a heavy user, chances are you won’t make it through the day on your smartphone with a single charge. About the only thing that changed since, is wireless charging: more and more manufacturers are embracing the technology, and, while you might not be a fan, or you might consider that wireless charging is still far from where it should be, it is still the easiest and most convenient way of charging your phone.


Enter the Xtorm Wireless Power Bank 10.000, a battery pack that combines the traditional way of charging your smartphones and tablets (via its USB output, and a cable), with the “new” wireless technology. The Xtorm Wireless Power Bank 10.000 supports the QI standard, which means that there is a wide range of devices compatible, from Nexus phones to Lumia devices.

In the box

There’s everything you need to get started right in the box. The juice pack itself is pre-charged, meaning that you can start draining it by charging your smartphones as soon as you get it out of the packaging.

There is also a USB charging cable supplied, which you can use to charge your smartphones (or tablets), but there’s no A/C adapter (like with other Xtorm products of the past), meaning that you can charge the Wireless Power Bank 10.000 with any charger, or even with your computer’s USB connection. You’ll use the same, supplied, cable for that, and we’re positive you  have a charger lying around unused.


And, since this is a product meant to save your life while on the go, there’s also a protective pouch inside the box so you can carry the juice pack safely around. …oh, and there’s a manual as well, which you’ll never read, as the operation is so easy and the layout of the product is self explanatory.


10,000mAh is what the Wireless Power Bank is rated for, meaning that on paper it should be able to charge, for instance, the G Flex 2, with its 3,000mAh battery, at least three times.

Sadly, that was not our experience, and we reached out to the manufacturer for comments. This is what Xtorm had to say: the “wireless charger has an efficiency of 72%. That means you can charge with a 10.000mAh battery, 7200mAh. This is an average number. It depends on the model of your smartphone if you can charge a little less or more.


While we did not use wireless charging on the G Flex 2 (for obvious reasons), we still didn’t manage to top it up three times. However, we switched to wireless charging with our Lumia 930 (yes, that limited edition gold/white one :D), and even charged two phones at the same time.


The size of the juice pack is manageable. It’s 140x80x17mm, while weighing 266 grams; this means that you won’t have problems carrying it around in your bag, backpack, purse, manpurse, or cargo pants. There are only two ports on the Wireless Power Bank: a USB output (rated for 5V/1A) which is the place you charge your phones from, with a cable, and a micro USB input (5V/1A) which is the port you will use to top up the battery pack itself.


The top side carries the QI wireless charging component, specifically called out, rubberized to avoid disconnection of slippery phones. It outputs 5V/0.5-1A.

Build quality

The Xtorm Wireless Power Bank 10.000 is fully made out of plastic, with some anti-slip rubber inserts on the top, where the QI wireless charging area is placed, as well as on the bottom, so that it won’t slip off surfaces. The finish is matte, and it looks and feels like a polycarbonate phone’s body (the original HTC One X, if you can remember that).


It doesn’t look cheap though, and, while plastic is a relatively cheap material, the unit feels sturdy and reassures you that it will probably withstand a drop or two without braking.

On the right hand side there’s a button which wakes up the unit from its sleep mode (for checking battery status), and the left side holds six LED lights. From right to left: orange (for operation), blue (for wireless charging underway), and four white ones (for indicating approximate battery life, in 25% increments – these also flash to indicate charging, and its progress).


Battery life

Your mileage may vary, depending on the devices you own, and charge. On paper, a 10,000mAh battery should roughly charge about the same amount of juice in phones, but, as we saw above, it’s not the case.

While we couldn’t charge the LG G Flex 2, and its 3,000mAh battery, three times, completely, we managed to almost achieve it with the HTC One M9, and its 2,840mAh unit.


We could charge the Lumia 930 three times, from zero to 100% (it has a 2,420mAh battery), and we used its QI wireless charging capabilities. Yes, it is somewhat slower, but it is also more convenient to just place the phone on top of the power bank.


We also charged phones simultaneously, via cable, and sans, without a problem. What we have seen is that the battery life of the bank itself seems to have improved after three or four charging cycles, which is understandable, as it has a Li-Ion battery pack inside.

Fully charging the Xtorm Power Bank with a smartphone charger or computer can take anywhere between six to eight hours, depending on the charger itself, and the battery level of the juice pack. If you plan on charging it overnight this is not an issue but if you happen to run out of juice during the day it might be troublesome. Since this product represents an emergency charging solution, and not a regular, day-to-day single source of power, we really don’t mind the rather long charging times.


+ QI wireless charging
+ small, portable, lightweight (considering its capacity)
+ solid build
+ large capacity
+ charge indicator
+ simultaneous charging of two devices (if one is QI enabled)
+ included cable
+ included pouch


– somewhat pricey
– could/should really deliver closer to rated output power
– no charger included

Pricing and availability

You can purchase the Xtorm Wireless Power Bank 10.000 directly from the manufacturer. It will cost you, as listed, €79.00, but you’ll also have to add some shipping costs depending on where you live (and, depending on your location, VAT, as well).


If you often find yourself commuting, hiking, traveling, or doing any activities which keep you away from a power source (wall outlet), and, if you have a QI enabled smartphone, the Xtorm Wireless Charging Bank 10,000 is definitely a product to consider. There are, of course, other products on the market (this one is Xtorm’s single power bank with QI compatibility though), so make sure to check those out as well before making a decision.
