A Chinese enthusiast has collected a power bank for 27 million mAh.

Chinese inventor and YouTube star Handy Geng is tired of the fact that regular power banks are not sufficiently capacious and are discharged too quickly. And he assembled his own version — a monstroidal device for 27 million mAh. You can’t put it in your back pocket, but you can charge 5000 phones at once from it.
Structurally, this is an impressive aluminum box measuring 1.8×1.2 m, inside of which an unknown number of flat batteries for electric vehicles are stacked. For ease of transportation, the mega-bank has wheels, and on its outside there are 60 sockets for simultaneous recharging of a large number of gadgets.
The capacity of this monstrous device is so large that Handy Geng easily connected a TV to it in an open field, and then a washing machine. There is enough energy for a voracious electric furnace, and the peak of possibilities is charging an electric scooter to take a giant power bank on a trailer even further. To where he will still be needed.
