Handy Geng, a Chinese electronics tinker and influencer, has constructed a massive power bank with a 27,000,000 mAh capacity. In January, Geng uploaded a video to YouTube that detailed the process of creating the power bank. “Seems like everyone else has a greater power bank than mine,” he joked in the caption. It does not make me happy. As a result, I created a 27,000,000 mAh portable power bank.”

According to a post from MySmartPrice, Geng thinks that his power bank can charge more than 5,000 phones with 3,000 mAh batteries. The inventor appears to have employed a big battery pack similar to those found in electric automobiles.

The power bank is 5.93.9ft long. The massive device comes with a protective frame and roughly 60 connectors. Through its output charging connectors, it can accommodate a 220V electrical potential voltage. And there’s more. This power bank can be used to power key electronic devices such as the television, washing machine, and even electric scooters.

For simple transportation, Geng has included wheels in the device. It resembles a regular off-the-shelf power bank, but it’s far larger. It overcomes the problem of frequent power outages in residences, despite being too large to carry about on travels.

Aside from the gigantic power bank, Geng’s YouTube channel is chock-full of humorous footage of the inventor creating bizarre technology including flying wings, a DIY security patrol mechanism, the tissue-heating machine, and more.
