I just need a power supply cord to charge my jump starter system. Where can I get one?

Jump starters usually contain the charging circuitry that regulates the current supplied to the battery whether charging from a car cigar lighter socket or a mains adaptor.

The mains adaptors supplied with jump starters are mostly generic power supplies as provided for many vaguely car-related 12 volt accessories and devices - many car enthusiasts have accumulated half a drawer full of them varying from around 13.5 volts to around 14.5 volts providing current of around 800ma to 1,2 amps.

Recharge might be a little slow if a lower output than 500ma is used but there is practically no upper limit.

you will still need power supply, you can attach it to extension cord,

These jump starters have their own batteries, they eventually die too ...

If the part department doesn't have the answer ask to be switched to tech support.

Where can i buy the power cord to recharge my Power on Board 12 volt 450 amp

I have the same problem: today I tried a 12 volt, 1500 milliamp (1.5 amp) power cord and it has charged mine halfway, so far. It fits the plug in, but not certain, yet, that it has enough power to fully charge.

google the name and model #. The home website should come up in search. Go to site, and look in support, or replacement parts.

should just nee a regular extention cord
