Convert a 12V 1A charger to run off 12V 300mA? Answered

I have a Nitecore Intelicharger i2, which has a 12V dc input for power, however it requires 1A of current to function. The power supply I want to power it with can only output 12V at 300mA. Is there a way to mod my charger so that it runs on a lower current.

Thanks!

I do have the larger brother of that charger, the i4, and I really like it. Charges just about everything reasonably well. Only complaint I have is that it is a little slow. However, this thing does not need a 12V external supply, it can be powered directly from the wall. So why do you need to power it with 12V, why not 120V?

You could try to just power it with that 300mA max supply, and see what happens. It that does not work, you can probably hack the firmware on it, or see if there are ways to replace the current shunt resistors with higher value ones, so that it charges at an even lower current. However, that means that it will charge the batteries at a much lower rate. Really for me at least that would be more effort than it's worth. Just get a cheap 12V 1A power supply.

Free energy people like you are a bane to the worst things in the world or are you just uneducated.

You want to run a 12 watt device from 12v x .3A = 3.6 watts power supply that is just thoughtless incompetent, I don't want to use the S word you really deserve.
