DC will charge faster than AC, other than that it doesn't matter, a charger charging a battery at say 5 amps isn't gonna be any faster than another charging a battery at 5 amps.

Generally unlike smart(donkey) above the numbers you are looking for in a charger are watts per channel. I use a single charger but I have one that will do 200W that means up to 6cells lipo I can charge up to 10Amps

Now if you are using high quality batteries charging at that rate for say 5000mah batteries will not be a problem.

But the faster you charge a lipo the less overall life you will have.

I have seen somewhere a 200W 4 port charger but once I looked further it was total 200W and not per channel. and with 50W you were limited to something like 5A at a 4cell at 6 it was like 3A but I don't remember which one that was.


Just some info as I don;t use a multiport charger


Also to note that you need a power supply at least 20% higher in wattage than your charger.

Agree as if you charge the battery at 20amp it will take only around 15min..... I tried it before using a silverback 60C pack and notice 2 things. Not much different in run time as I only race 8min and if I set the cutoff to 3.2V I can get well over 12min run time with that pack (touring 4.5T) and it have a lot more punch than my normal setting which is 10amp. The main issue is not the charger, it is more like if your battery can handle the high charge amp....

I once drove 120mph on the Turnpike with my Thunderpower 610 in tow.

Beat that.

This is a good point. The charger's advertised Amp (output) rating is sometimes only at a stupidly low voltage to make the charger seem higher spec.
So check out the chargers rated W output, not just the Amps if looking for chargers.
