Watch: The making of the world’s ‘most powerful’ power bank with 2,70,00,000mAh battery

While brands are fighting to create a power bank with bigger battery packs and fast charging, a Chinese influencer, Handy Geng, may have made the world’s most powerful power bank in his workshop. The influencer claims that he has created a power bank with 2,70,00,000mAh battery that can power up to 60 devices at once. For context, average power banks that are available in the market packs a 10,000mAh to 20,000mAh battery with 2-4 charging ports.
Although made for comic reasons, the huge power bank functions properly just like any other big battery. Geng has even shared videos on Weibo and YouTube showing how he made the power bank from scratch. The title of the video reads “I Made a 27,000,000 mAh Portable Power Bank”.
For this device, Geng used a huge flat battery pack, similar to the ones seen at the bottom of an electric car. To make it resemble a power bank, he encased the battery pack with a silver metallic casing. For power output, the influencer has added 60 output charging ports that support up to 220V of electrical potential voltage.
Due to its humongous size, it is difficult to say that the device is portable. But Geng is seen dragging around the power bank in the streets. While popular power banks can power laptops, accessories and smartphones, this giant power bank can also power a television, washing machine and other electrical appliances.
As per Handy Geng, his power bank is capable of fully-charging 5,000 smartphones with 3000mAh battery capacity. He also mentioned a few other specifications of his unique creation that you can see in the video below.
