Power: Absolutely disappointing. I have now tried 3 times to use but the charge level roars when only so in the basement. For example, last weekend: the fully charged PowerBank connected to the phone, went to sleep and former enabled. The next morning was rather noisy display 3/4 1/4 still remaining. Since I am first of all assumed that an operator error I have daytime power bank fully charged and the evening started a second attempt, and achieved the same result. If my device has a battery of 2400mAh should I do with this device surely can at least 3x load and not perhaps 2x.
In addition, the unit discharges very quickly even if it just lying around unused (completely off).
Conclusion: From the outside and the price (~ 20 EUR) an attractive proposition, but not usable. So and now I find out how I anstoße my first returning on Amazon.
