Formerly, Richard III offered his kingdom in exchange for a horse. Today, that does not do the same for a few Watt power facing a desperately unloaded smartphone? And this is especially true on the outside, away from any easily accessible electrical outlet. Delivered with a cover and a cable (USB / microUSB) for recharging, this extra battery is capable of delivering up to 3.4A of current to two different USB ports and allow simultaneous charging of a smartphone (1A) and a tablet (2,4A). The charging status is indicated by 4 blue LEDs each representing 25% of total capacity. According to its manufacturer, it takes between 3 and 10 hours to ensure full charge of the battery then recharge a smartphone or tablet in 1 to 2 hours. Certified IP67 (dust and humidity), reinforced by a rubber coating to withstand without damage consecutive impacts to a drop of 2 m high, this product is particularly intended for outdoor use (hiking, camping, sports, ... ). The ability of 6A / h (22,2W / h) is sufficient to charge several times a smartphone. But with a mass of about 240g and current technologies could expect a much greater capacity.
