Hi,

Do these chargers need an external power supply. I am looking at getting one soon. Thx guys,

No, a power supply is not required. It can be used either way actually, plugged directly into a wall socket, or with a power supply. (Just be sure to use the proper inputs of course.)

They also have a newer version that has more power, which if nice if you are running electrics, especially E 1/8 or something similar (Probably overkill for a nitro). This one can produce higher power on a DC power supply (150 watts), but still works without, plugged directly in to an AC wall plug (90 watts):

Oh very nice. I might have to go with this one instead, thx

+1 on Hyperion chargers, wouldn't use anything else. Ensure you get the model with Lipo storage mode.

i used that exact same charger for 2+ years and never had a problem with it. they are great chargers.
