I’ve been a road warrior for years now, and have gone through over a dozen different Portable USB batteries – they have all either broken (Looking at you, fancy LiPoly chargers!), I’ve lost them, or I outgrew their capacity.
Capacity is the name of the game with this little device! While it is heavy, weighing in at 247 grams (Slightly over a half pound), it packs in every feature that a road warrior would need:
* 8800mAH capacity
* 2 standard USB ports, one outputting at 5V-2A
* Charges via a standard micro-USB cable
* Simple On/Off
* A ring of LEDs around the power button show capacity remaining (Both charging and discharging)
* Comes with a handful of different adapters, though they aren’t needed
I picked it up at a local Microcenter for less than $20, thinking it would be trash — but it’s survived dozens of drops, hundreds of charge/discharge cycles, water, mud and more than enough to have me come to depend on this little guy!
The best part is the 5V – 2Amp output – this allows most devices to enter a fast charge state, which is noticeably quicker than with a standard socket.
On a recent 6-hour flight, I kept both my Android phone and my power hungry Nexus 7 plugged into it. I played games, listened to music, or watched movies the entire time on the Nexus and when we landed both devices were at 100% AND the little USB battery was still at 75%.
In fact, I have yet to drain it beyond 50%, and that includes a 12-hour day of Geocaching with my phone’s GPS on and the screen fully awake.
It also holds a charge for a long long time — I’ve left it alone for 6 months, only to come back and see it’s still at almost a full charge.
If I had an gripe with it at all, it’s that it lacks an attachment point, which is corrected with some epoxy and a trip to the hardware store.
