I am putting together my first charging setup and I am planning on purchasing a Revo GT500 charger and will be charging 2 2s 5000 mAh 70C gopacks at a time, looking at the following for a power supply https://www.rlpower.net/collections/...ith-a-usb-port. Does anyone have any experience with these? A progressive rc calculator puts me at 205watts @2C and 105watts at 1C which is probably all I will use. The more compact the better, if anyone has other suggestions let me konw.

Thanks,
Ryan
