The Chinese ‘youtuber’ Handy Geng has made the largest external battery on the market, thanks to a welded metal frame that forms a 27,000,000 mAh ‘portable’ charger , equivalent to about 900 common external batteries.
In addition, the device is equipped with 60 plugs that could supply power to 5,000 mobile phones with 3,000 mAh batteries, laptops, other external batteries, electric bicycles. TVs or washing machines can also be connected to it.
The battery measures about 1.8 meters long, 1.2 wide and 30 centimeters thick, and to transport it the YouTuber uses a rope tied to a base equipped with wheels.
Its creator, who is a fan of crafts, explains that with this external battery, ” you absolutely do not need to worry about the lack of electricity when you are outdoors, or worry about a power outage”. At the moment, he has not reported on the method to recharge the powerful portable battery when it runs out.
