Charging the external battery:
2.0 USB in the PC, microUSB in the battery and already it is being charged.
Charging the smartphone:
Press USB 2.0 into the connector on the external battery, microUSB in smartphone / camera / tablet and knob directly to the USB connector from the battery and the tool is loaded
The battery has to charge a power of 2.600mAh, that's enough for my mobile phone battery (Samsung Galaxy S3) or even the phone battery (the 1.000mAh has) more than twice. That's enough for a weekend away from home without power, for nen day trip with lots of pictures or a teenage couch evening with smartphone gaming.
Since this battery pack is warm and barely even heats the smartphone, you can load his phone even in the purse or pocket without what happens.
Practically also, if one takes it as a handbag accessory: the flashlight. Because compared to other lights on the battery, this makes here its name and really bright lights.'ve Recently the real needs in the parking garage.
So, I've been that my Samsung Galaxy S3 loaded, both my Kindle, my kobo glo, my camera of Nokia (with other cables) and a couple of my Bluetooth boxes, so far I could not detect any incompatible Geräe.
My Conclusion:
Small, chic, is not warm, invites fine and the flashlight is great too. In addition: really cheap. From me 5 stars.
