My Galaxy S4 I could in about 1 hour and 40 minutes fully charge (Mumbi replacement battery: 2.900mAh). Neither the charger nor the replacement battery of my smartphone have become overly warm. Even in a stress test with 2x Power Bank, 1x and 1x Smartphone Tablet I could see no unusual heat build-up after about 30 minutes.
Conclusion:
With this USB charger from 1byone® one is really well served when performance and appearance are the main criteria. The aluminum surface (at the four ports) evaluates my opinion on the device. The excellent loading performance, the processing and the chic design in my opinion justify the price. Finally, I would point out that I was asked this charger as a free test articles. My rating is unaffected objectively and not fined.
