So I bought a ThunderPower LiPo charger off Gary a while ago, and for now I've been using a tiny 12V 5A power supply with it. Of course this means I can only charge my 5S LiPo very slowly. What kind of current or power rating should I be looking for to get the most out of the charger, and can anyone recommend a product in particular (as reasonably-priced as possible)? The charger itself is a ThunderPower TP1010C, and takes 11-15V input.
