DA polisher/Power inverter

So awhile back I asked if there are any good battery powered DA polisher and I didn't get anywhere with it.

So just to recap...my issue is, I live in a condo complex and my parking spot is nowhere near my unit.

Is there anyway to run a DA polisher with a power inverter with a dedicated battery just for that particular use. If possible, what wattage should I be looking at to work with which polisher.

Thanks for your help!

Been there, done that (12 years ago). I think mine was a 300W rated inverter. Used a 70Ah gel cell IIRC.

I found the formula/criteria for what I need ...it's amps x volts = watts...so if I'm looking at the Porter cable which I believe is 3.7 amps @ 110 v I'll be lookin at a constant 407 watt inverter. It would be a safe bet if I go with the 750 watt since the current will be much higher at start up surge.

Anything missing?

Larger inverters are more wasteful. By this I mean that even with no load a 750W inverter will consume a lot more power than a 300W or smaller. Some rating plates are over-stated "locked rotor" current and not representative of the operating power required for the device.

Is there a chance you have a neighbor with a spot near an outlet, or can get permission from the office to park in a visitor spot near an outlet on a Sunday? Just a few alternative thoughts

Unfortunately, the neighborhood is a park like setting and the parking spaces are on the outskirts of the property and nowhere close to an outlet.
