Not sure how compact your looking for, but the rivergates are rather small. And my buddy uses a converted XBox 360 "powerbrick" ps, thats isnt too bad in size.

I have a rivergate, it's a monster! But it's 30 amp...

The most compact I've seen would either be the LRP 14 amp http://www3.towerhobbies.com/cgi-bin/wti0001p?&I=LXLGF3

or the Radio Shack 13.8 amp http://www.radioshack.com/product/in...ductId=2103960

Those are still large. I was pointed to this one:

185x88x47mm

However, its 15 volts, which I know my main Lipo charger has no issue, but I'm worried its too much for my Pitlight and AA/AAA charger since their DC adapters are only rated for 12 volts.

Thoughts or other alternatives that are 12volts?

I'm using two of these, the 12v, 42A supplies. They're 12v, max I've seen on a DVM is 12.2v under loads up to 30a. It is bigger at 51mm x 83mm x 279mm. This is the second one shown, the others are bigger.

Thanks for the link. Unfortunately those are still bigger than the one I posted above (especially length).

I guess I could use a resistor, but. Thats more to carry or lose and those can get pretty hot.

Maybe it’s little brother? About the same size, gets the voltage rating down to 14V, gives up some power. Both are lighter than most.

I have the 350W-15V job you linked, and the ProgressiveRC service & delivery was solid. FYI mine and the 2 my bud has all run 15.1~15.2V loaded or unloaded. Won’t work with the older 15V max rated chargers I have without a diode (better solution than resistor).

You could try modifying a computer power supply. Mine is only rated at 9 amps 12v (I can only use 5amps) but you can get them rated for more amps. I paid $5 for a used one from a local computer store.

Have used one of these in the past and they work well

Only good for 140 watts or so though (12v @ 12 amps)

Yea, with hobbyking you get what you pay for. Look at the first comment.


I have used computer power supplies in the past. They are simply too big. I have an astroflight right now, and its fine but again I need even more compact.

The P350 is looking better and better. I talked to the pitlight manufacturer and they say it should work. So that only leaves the AA charger.
