A monster of power!

This battery can be recharged daily smartphone for a full week more than enough traveling.

With its reserve and three output ports, it enables completely and simultaneously charge TWO tablets Android + smartphone!

Of course, it can recharge ALL devices that charge via USB: smartphones, tablets, GPS, GoPro, Bluetooth speakers .. the list is long, and not limiting.

Big advantage compared to other high power battery I own: it simply recharges via USB, no need for specific charger.

Incidentally, the battery is equipped with an LED that can be used as a small flashlight troubleshooting, it is not necessarily essential, but it can be handy. The lamp function can send an SOS in Morse flashing: it may seem gadget, especially with a LED that does not in kilometers, but that's the kind of device that can save your life.

Only drawback: The battery weighs 475 grams .. at this power level a value quite correct.
