The Xtorm EVOKE (AM121) solar charger is a large-sized powerbank that features a 10.000mAh lithium polymer battery pack (can be used to charge smartphones up to 5 times and tablets up to a single time), two SunPower high-efficiency solar panels (4.5W), IPX4 certified (protection from splashing water, no matter the direction) shock-proof rubberized enclosure, micro USB input charging port and two high-output USB charging ports (5V/2.1A).
The Charger is protected against splashing of water. On top of that it is possible to charge two devices at the same time as it has two USB ports.
The device also includes an APM chip which automatically decides the correct charging speed and efficiently divides the power between attached devices and several electronic and electrical protections against overload, overcharging and overheating.
This robust Charger can be recharged in two ways; via USB and the built-in solar panel. Via the Micro USB port with a 5V-1.5A input the battery is charged in no time. In tests, it took around nine hours to fully recharge the 10.000mAh internal lithium-polymer battery of the EVOKE. This was under direct sunlight on a cloudless day. It will probably take longer when cloudy or in less sunny areas.
