I think there was already a thread somewhere on this but never mind.

I think one thing to keep in mind is to look a bit in the future. More and more batteries are 2C or 4C. That means charging with 10A or 20A on a 5000mAh battery. I think the latest is that the charger input voltage should be 24VDC iso 12VDC, so be sure you find a power supply that can do that.

I am using now the iCharger 1010 (from hobbycity) with which I am very happy. For me that means I can charge at 1C a 10S 5000mAh package (=200W). I use 2 chargers and 3 packs. In that way I charge quicker then I can fly. Each charge takes about 45minutes.

People that charge at 2C or 4C use an iCharger208. This can charge with 350W. They can charge (with 24VDC input) a 5S pack in 15 minutes. You need 2 chargers and in theory 1 pack.

These are some options so you have to figure out what works for you. Hope this helps!
