One tends to think a microwave uses little power. Here is a battery operated unit that puts it into perspective. It starts out by saying how it can heat up 11 lunches? Now this has a 40v 8ah portable tool battery (s) so that sounds pretty good right? Keep reading only to find out that on High output (500W) which is about 1/2 of your standard 120v unit sold today, it will only work for 4 minutes before the battery needs a recharge. If one looks at the video they show 2 batteries installed so I will assume that is with 2. A bag of microwave popcorn in a 500w micro takes 4 1/2-5 minutes so it won' be heating much popcorn unless you have spare batteries to pop in as they fail.

I guess those 11 lunches were donuts or something similar that requires very little warming up! Gotta love marketing.

Just something to think about when making the decision to run the micro for any extended period off the inverter or genny.
