e-Electric Batteries & Chargers > Radio shack 3 amp is it ok

Ok, here is my question I just bought the 22-504 12-volt power supply that Radio Shack makes and I notice it is a 3 amp model. I am going to be running a triton charger from this. Will this be ok or did I buy the wrong thing. I am not good with this stuff in terms of amps. I am just going to be charging some GWS batteries which are about 700 mah and then my 8103 and RD6000 radios. I also have birdseed and a 1020 mah Li-Pol battery. I know my rx batteries are around 700 mah for now and I will be getting bigger in the future probably 1200 mah. Is this charger going to be enough for me. Fast charge is not that big of a deal because it will be used to charge inside and if I need to I can hook it to my field charger or my car battery while at the field.

yes it should work. Is it not ideal as it will only allow you to charge using 2-3 amps max. The Triton, as per the specs below, indicates it will charge up to 5 amps so you are basically 'short' on that side.

Input Voltage: 10-15V DC
Battery Types, # of cells: 1-24 Nickel-Cadmium cells (1.2-28.0V NiCd)
1-24 Nickel-Metal Hydride cells (1.2-28.0V NiMH)
1-3 Lithium-Ion or Lithium-Polymer cells (3.6-14.8V Li-Ion/Li-Po)
3, 6, 12 Lead-Acid cells (6, 12, 24V Pb)
Fast Charge Current: 0.1-5.0A linear (2.5A max. for Li-Ion/Li-Po)


what amps do is they're like the size of the water hose you fill up your barrel with. More amps meanslarger hose and it will fill up quicker. Here is a rough example:

Take a 1000 mah battery (1.0 amp or A). charging at 1A would charge this battery in 1 hrs time. charging at 2A would only take 30 min. So as you can see more amps give you more flexibility. This doesn't really come into play until your batteries get really big, say 2000 mah or bigger, or you're charging multiple cells, say 6 or more. I guess it really matters in what you're looking to do with this unit in the future. If what you indicated is all you see yourself doing, then what you're looking at shoud be fine. If you see yourself needing more power in the future, you should look for a larger power supply. I personally use one of these:

10 Amp AC/DC Power Supply
Part Number: PS2-12US from

http://www.fmadirect.com

they can be found in other places and for other prices. you could also go the 'old computer power supply' outlet. there have been a few posts about that here.

Good Luck,

Yeah I am taking it back. I didn't open it and yesterday I ordered the 10 amp one from bsless.com. It was $10 more, but well worth it. I think I will be much happier with the bigger one. Just in case I need it. Now I just need the Triton to show up in the mail. Thanks for you definition of an amp, I just wasn't sure about it.
