First impression positive 1

I already have an external battery pack from the anchor is not very comfortable for mobile use due to its size and weight. That's why I was looking for a smaller powerful pack and came across the RAVPower because of the good ratings. Delivery as usual at Amazon quickly and on time. The pack comes with a charger, a small manual in flawless German, which is not always the case with devices "Made in China".
The shape of the packs can be compared with a slightly larger disposable lighter, the rounded edges, it fits comfortably in your hand. The processing is perfect, nothing wobbles, the sockets, lamp and the switch are fitted clean.
The Pack was charged to about 75% (3 charging lights on).
A first charging filled my iPhone 5s in an hour from 55 to 100%.
I can not say anything because I'm charging my devices at night Regarding recharging the packs.
Conclusion after the first few days: Shapely part, very clean processed and doing what it should.
