AC=>DC adapter

ok, i recently got a battery charger for my remote controlled car. when it came, i noticed that it had no plug, but instead it had two aligator clips. so what i need is an AC->12V DC adapter that you can clip aligator clips to. so like: wall outlet->adapter->aligator clips. does anybody know where i could find something like this?

Sounds like it is made to work off a 12 volt battery. You could charge you remote car form your automobile.
You could use a 12 volt auto battery charger as the source for new battery charger.

Get a 12 V car battery trickle charger with alligator clips and just connect the aligator clips together. I think this would be the cheapest/economical solution, plus, you'd have a car battery charger for the inevitable dead battery.

Watch it charge a few times, This still could fry your battery.

ok, i found a car battery charger here: http://www.autobarn.net/acse-1052.html

it has a 2 amp trickle charge, a 10 amp fast charge and a 50 amp super fast charge. the dc charger that im going to hook my remote controlled car up to is a 3.2 amp fast charger. the fuse on the charger says 7.2 amps. so i know that the 10 amp fast charge is too much, and the 2 amp trickle charge is too little. i've searched for a while and all i found were like that. can anyone point me the direction of one that has a 12V 7.2 Amp output?

EDIT: and whats the standard output in amps for a car battery?

The amp rating are the max. I doesn't mean it puts out 10 amps all the time. As the voltage of the battery rises closer to full charge the charger output lowers.

Geez, 70 bucks.

I was thinking more of 15 maybe 20 dollars for a simple trickle charge/booster you should be able to find at any NAPA, Arnolds, Oreilies, etc...

I've got a simular charger for my remote controlled boat. The idea is that you can recharge your batteries from a car battery while you are in the field. You can have a spare battery on charge while you are using the other one. Just get a small trickle charger and a Gell Cell 12 volt battery and you will be good to go.

i was hoping that too, but a trickle charger only outputs like 10mA or something like that. i need something that is going to keep up with the 3.2amps output that my current charger has.(the one with the aligator clips)

It isn't neccessary to have it keep up with the 3.2amps... If you just want to charge it, buy a SLA 12 volt battery rated at 8AH and you'll be fine for a long time. Then use a standard car charger to charge the battery you bought.

I got a 12V 8A/H battery from Interstate Batteries to boost the speed of a Power Wheels toy (put in series with a 6V that came with it). The speed difference was incredible, but I digress.

Have fun and good luck!

I hope you put air bags and seatbelts in that Power Wheels!! Great idea! My kids would love it.
