RAVPower 3rd Gen 15000mAh 4.5A output External battery pack

the battery is charging the smartphone and tablet unusually quickly. With the different voltages that are displayed on the port, I can not do anything. No matter where you anschliesst- the device it works. It was noticeable that the Galaxy S3 loaded only to 85% was-whatever reason. S5 properly.

Should I trust the charge gauge, I do not know. In any case show still all beams of LED, although I have quite a bit loaded. Theoretically even a bar his way.

Minus: If you connect a device already loaded again, indicates the Power Bank that it loads again. The likely due to overvoltage risk actually not be. But I'm not sure if he really invites, or it indicates only incorrectly.

After a few months of use I can recommend the device as a conclusion. The charge indicator work great, although initially confusing. You can phone or tablet invite at least 5 times.
