The two USB charging sockets each have 1A and 2.1A and the integrated battery 10400 mAh, here have been repeatedly loaded tabs and smartphone, which goes as planned with one battery charge well.
The charging time from Poweradd himself with 6-8 hours is unfortunate but how it is.
The battery charge level is indicated by 4 blue LEDs. They also light up when a Tab or smartphone is loaded, while these show the charge level of Poweradd on. Since my Tab loses rather quickly on energy, I can mount the Poweradd than 2 battery use and now significantly longer works, that's great!
My Conclusion
The article makes Total even through the silver shine a high-quality and sophisticated look, I can recommend it.
