The Easy Acc iChoc has three reasons made the race: With 135 grams (weighed, here the package weight is specified with 159 grams) it weighs little more than a smartphone. The compact, covered with a grippy rubber housing fits in the pocket or inside pocket and is not bulky since. What convinced me not least the integrated charging cable with Micro USB, thanks to which you have to carry around a USB cable.
In addition, the battery has a second USB charging socket, the charging cable also for devices such as iPhone or iPad fit. There are two devices can be charged simultaneously, which increases the charging time. Only a smartphone, however, is relatively fast fully recharged. Conversely, the empty iChoc leaves itself also refloated full load. On gimmicks like the LED "flashlight" I could do without. Otherwise, even the successful design highlight in this class is a rarity.
Penalty for the charge indicator: Four blue LEDs can only vague conclusions about the charge to (in 25-percent increments). And the battery is while charging a lot of heat from.
Despite a recommendation. Has proven itself in use.
