Model Forum / Radio Controlled / Land Models / March 2004PC Charger supplies
I've seen a lot of postings for people using PC power supplies to "charge batteries". After some investigation I see that the PC power supplies the charger which actually charges the battery. My NEWBIE question is, Why? why would you use a PC power supply to power a charger, instead of just plugging the charger directly into the wall!? Being a computer guy I have a lot of power supplies that I could use if there is a good benefit:-) Thanks all! > I've seen a lot of postings for people using PC power supplies to > "charge batteries".

They only use a 12V DC external power supply. Some of my chargers have the capability to use 120 Ac or 12V DC. My chargers are not high end though. So...many folks own a 170.00 RC charger and instead of spending another 140.00 on a quality regulated DC power supply they take a computer power supply that is not regulated and make it work. > Many high end Rc battery chargers do not have an internal power supply > that works at 120V AC.

I'm looking at chargers, but the ones that I want (obviously) have a power supply... Thanks again! Many times when you use an ACDC charger off a wall outlet, they charge at a slower rate. It's a shame that they skimp on the power supply. Matt > > Many high end Rc battery chargers do not have an internal power supply > > that works at 120V AC.

What makes you think that PC power supplies are any less clean than any other power supply? Don't you think PC's might be sensitive to voltage spikes? > > > I've seen a lot of postings for people using PC power supplies to > > > "charge batteries".

Just regulated. On the Pc supplies you need to keep a load on the 5V side to keep the 12V constant. |
