USB powered microwave oven

I have seen all kinds of strange USB gadgets, but this might even be more useless than USB coffee cup warmer. World’s Smallest Microwave Is USB Powered article tells that there is now an USB powered microwave oven. Beanzawave is said to be the world’s smallest microwave.

Because of the limitations of the power available from USB port this can’t be very powerful.
USB port voltage is limited to 5.25V maximum and the available maximum current is normally 500 mA (900 mA on USB3). So the maximum power you get is 2.5W or 4.7W. A typical microwave oven is 500W to 1000W. When it takes for normal microwave around two minutes or so to heat up a cup of water or a piece of food, it would take ages for such small microwave oven with less than 1% of the power to heat up anything.

When reading some more articles it seems that this device could have some use after all. Beanzawave USB-Powered Beans Microwave is What USB Was Created For article tells that there is Lithium Ion batteries inside for on the go beans heating. So it looks like there is actually a small higher power microwave powered with Lithium Ion batteries and then there is USB charger for the built-in batteries. Measuring just 7.4 inches tall by 2.6 inches wide and 5.9 inches deep this would really be the world’s smallest microwave oven.

I think this product will lead to disaster eventually. A disaster that can be seen on-line afterwards. After seeing all of these Youtube videos of people putting anything they can to microwave ovens…
