Youtuber builds the most powerful power bank in the world – 27 million mAh capacity

Power banks are popular for charging a smartphone on the go. Usually there are such power banks with a maximum capacity of 30,000 mAh. But what is normal, the Chinese Youtuber Handy Geng thought and built what is probably the most powerful power bank in the world. The road was extremely rocky, as Geng also shows in his YouTube video (in Chinese with English subtitles). In his workshop he set himself the goal of building the world’s largest power bank and finally made it.

The result of the work is impressive. The capacity of its power bank is an impressive 27,000,000 mAh, with which a 3,000 mAh smartphone can be fully charged several thousand times. According to Geng, up to 60 devices can be charged at the same time with his power bank, and the corresponding 220-volt power plug connections are installed, i.e. no USB connections. This allows you to plug any device into the power bank, including a television, for example.

The mega power bank is also portable – at least in a broader sense

The housing of the power bank contains a battery that is also used in electric vehicles. However, it was modified by Geng and squeezed into a power bank-like housing. The mega power bank is also more or less portable: the video shows how Geng attaches a rope to the power bank and then pulls it around. The power bank also serves as a piece of sports equipment. He ends up fishing at a lake while watching a TV show on his power bank, doing his laundry in a washing machine and cooking himself something to eat.
