^^^ That's a good charger with a good rep, there's a lot of them in use here.

If you need more output power (charging 4S and larger, or big 3S lipos of more than 4000mah) and don't want to spend the extra time a 50watt charger will take due to current limiting by the charger to stay under its 50watt limit, there are a few AC/DC choices with more power. The Thunderpower TP610 AC/DC has 80watts and a 10amp max charge rate, Dynamite Passport Ultra has ~90watts effective and 8amps max rate and the Triton2 EQ has 100watts an 8 amps max rate also. Hyperion has an AC/DC charger thats 90watts with 20amp max rate thats fairly new.
