• Cordless Power Tool Conversion 18VDC to 120/240VAC

    Current is always determined by the load, which in this case is the tool motor. There's no way to supply too much current, only too much voltage. There is however the possibility of not supplying enough current potential - that is, if he did not use a beefy enough power supply (and wires, connectors etc.) that could handle the current that the motor pulled through the supply then it could fry it or be potentially dangerous. That's why it's always a good idea to give yourself some overhead and design power supplies that are able to handle more than the expected current load. This is the same reason that it's not dangerous to put too low a wattage light bulb into a lamp (the bulb won't get too much current), but it is dangerous to use a bulb with too high a wattage as it could draw more c...

This is the same reason that it's not dangerous to put too low a wattage light bulb into a lamp (the bulb won't get too much current), but it is dangerous to use a bulb with too high a wattage as it could draw more current through the lamp and possibly fry the lamp (not the bulb).

    The tool determines the current, you just need to make sure your PSU can handle supplying enough current. There's no way to give a tool or any electrical load too much current. the PSU supplies the voltage, but the tool pulls the current. Therefore, you should always make a PSU that can handle more current than you'll think you need, you can't damage the tool by using a PSU with a higher current rating. Beware though that your tools might have more kick than you're used to, so you may want to use some fuses or current limiting switches for safety. Also make sure the circuit in your home that you are plugging your tools into can handle the current or you may trip your circuit breaker.
