I bought this Power inverter from an auction, thinking that it will be a useful power backup when power goes down due to hurricane. However, I got stuck with not knowing how to charge it as there was no charging cable or User's Manual included. Does anybody know where I can get a copy of the User's Manual ? I believe this is already an old model, so anything in the 59-xxx series might help.

In order to produce 100 watts at 120 volts, the current will be 1.2 amps. But if you are producing that power from 12 volts input, the current will be at least 10 times the output current, and that would be at 100% efficiency, which is impossible to achieve, The efficiency could be assumed to be around 70% though, meaning that the current input required to produce 100 watts at the output would be somewhere around 13 amps. That's a lot of continuous power drawn from a cig. lighter, and the load might blow the fuse or breaker for that circuit.
in is for recharging the power bank and please note that it takes time to charge. and out is for your charging your devices when the bank is charged. yes you can use the same cable for both by inverting. and do not loop i.e connect the in to out whatever you do
Hi, i had the same problem and emailed the manufacturer. They suggested that i try to charge it up using a regular car battery charger, simply connect the crocodile clips to the charger and trickle charge for 3 to 4 hours. this worked for me. hope you have same success.
they did say that if this did not fix the problem then i needed to replace the battery, a used motorcycle battery will do the trick.
