Cordless Power Tool Conversion 18VDC to 120/240VAC
(hope the answer is not too late) No, it would not be overload. Because the number, let's say 450W, is just about the max output capability of your power supply. the actual power output of your power supply is subject to the actual power consumption of your devices. For example, ideally, if your device consumes only 1W, then the power supply only outputs 1W. However, even if the device need more than 450W, your power supply will provide only 450W which is its max capability. Acctually, you will see the output voltage of your power supply drops since the output current comsuming is excessive .
Very informative, thank you I copied this but I used a 12 v 30 a transformer and turned it up to its highest setting 14.8 volts. The tools operate no problem and as I just do the odd job with them, it was cheaper than buying a battery as the transformer only cost $35.00 aud on ebay
Do you think using the charging station would be a good "power supply" for wiring the battery to? There might be complications >'m not aware of but it seems like it should work.

My Charger died. Can I hook up a 19V laptop charger to charge up my power tool battery
seeing as how my 18volt dewalt cordless drill has a max output of 400 watts, (25amps, full load?), I would a expect a miter saw to draw a bit more power, but since it is at a higher voltage you need less amperage. Maybe try for a 20 amp powersupply. If you can find your exact product specs it usaully gives you the exact wattage output

I have a 24 volt cordless miter saw but I can't figure out the amps. I tried a 24v 5a power supply but that only moved the blade for half a second. Do you have any idea if 15 amps is enough or would I need more? Or is the problem something else entirely?
Wondering if anyone has tried upgrading the cells in a 18v ryobi pack??. I have 1 with a bad cell and am thinking about replacing the 10A/1300mAh , samsung 13Q to a 20A/3000mAh LG HB2. In theory this should more than double my operating time and add more available amperage.... Thoughts??
Hey Mchisi. Glad it worked out for you. If your model was anything like mine you'll eventually need to replace all of them.
I printed one of these and replaced a split leg lock with this on my Manfrotto 715SHB. Works a treat!

mah = milli-amp hours. This is how long the battery will last under load (1.5A for 1 hour in your case ie battery capacity) rather than the max amperage the battery can deliver. Under load the drill will drain up to 20A or more.
My battery pack is 18v, 1500mah which equates to 27 watts. Why do I need a 350 watt power supply if the battery is only capable of 27 watts?
Hi, Do you by any chance have Solidworks files for these? Thanks very much! Jaco.
Looks great! I have a cordless blender and I was wondering if you think that this would do the same trick. It seems to me that under load that cordless tools would draw similar power to that of this blender (rated 400W). I have a quick question, though. The battery pack says 18V, do I need to get an 18V switch power supply or would a 15 or 24 work? Also, if I get one that has more power (say 450W) would it possibly overload the blender?I plan on building a device similar to this one if it make sense to do so.Thanks in advance for any advice...
