Inverter: Modified vs. Pure Sine?

[0xfded]

I'm looking for some first hand wisdom regarding inverters.

I have no access to power in my apartment garage, not even via extension cord. I also like the idea of having 110v available when in the field. Maximum load would be running modest tools (all <4.5 amps), so I'm looking at the 600-800w range. I don't need to run a fridge.

I understand the differences between modified sine and pure sine. The latter is obviously better, but it's also between 2-4x as expensive for a quality unit. So I want to make sure I need pure sine before I buy.

Has anyone had any trouble running, say, an electric drill or dremel on a modified sine unit?

Hi Ox,

I'm by no means an expert on all the benefits of pure vs. modified sine wave inverters; but from the description of your situation (zero access to power), it might be smart to spring for a pure sine wave instead of modified.

Pure sine wave inverters will provide you with MUCH cleaner power much like what you'd get plugging into an outlet inside your home. You mentioned only using it for a dremel and drill, but since these are variable speed appliances the pure sine wave will be more efficient there as well. It would also allow you to plug in more fragile electronics (laptops, etc...), never know what you may use it for in the future.

Tons of research to be found online regarding these in the car audio, RVer's, and OTR truck driver crowds which should help you determine the right inverter option for you.


Best of luck!
