Japanese power tool manufacturer Makita recently unveiled a first-of-its-kind portable microwave oven powered by two large batteries that can be recharged and replaced on the go.

Mockups of a cordless microwave have been doing the rounds online as April’s fools for years, but this year Japanese power tool giant Makita decided to surprise everyone with a market-ready, battery-powered oven that can reheat dozens of foods and drinks on the go. The new Makita MW001G microwave oven is able to deliver 500W of power for up to eight minutes, after which it automatically switches to a lower power 350W mode to conserve battery life. It weighs just 19.4 lbs (8.8 kg) and can reheat about 11 refrigerated lunches or 20 drinks on two fully charged XGT 40V Max 8Ah batteries.

The new Makita portable microwave oven is apparently compatible with a variety of power tool batteries, the largest of which (33.5 Ah) provides enough power for nearly an hour and a half of reheating. As for the size of the heating compartment, Makita says it can ‘hold a large lunch box’.

The Japanese manufacturer recommends the cordless microwave oven for construction sites, in-car dining, and disaster situations, but you could probably find many more uses for it, if you can get your hands on it. The Makita MW001G is currently only available in Japan for a price of ¥110,000 ($840), but if it proves a success in its native land, it’ll probably make its way overseas as well.
