When the persistent trend towards third-mobile device I is not quite comfortable with the idea of being dependent on my small 3000mAh battery. Therefore, there had to be something bigger. The RAVPower is stable, processed excellent, trustworthy and hard. The latter may be seen as a disadvantage for me the weight is still absolutely in the green zone. The Power Bank comes with a small selection of useful cable and adapter and a carrying bag. The only complaint here: the bag itself is ideally sized for the battery. A cable in addition to pack is already cumbersome; take several apparently not provided. Here are a few square centimeter of material had been additionally quite useful. The RAVPower loads relatively quickly, the LED display is clear and self-explanatory. The instructions you need for happiness is not really - it is more suitable for entertainment than for orientation. Overall: Very satisfied!
