Handy Geng, a Chinese Influencer with an interest in electronics recently posted a video on his YouTube channel (via Gizmochina) titled “I Made a 27,000,000 mAh Portable Powe Bank”. Reading this title, hardly anyone can believe that it is actually possible. But, in the video by Handy, Geng has been shown using this power bank.
In the video, Geng says that his friends were fed up with the big power banks he had, and wanted to show that he had the biggest and longest lasting battery. The making of this power bank is shown in this video. Although no information has been shared about the battery, but looking at the flat and pre-fitted battery pack in the casing, it appears that it could be an electric vehicle battery pack.
To pack the battery pack and IC components together, Geng designed a metallic casing that looks exactly like a compact power bank. Next to it were installed input and output charging ports. As we mentioned, Geng installed 60 input charging port along with 1 output charging port.
It further showed that this power bank can charge up to 20 devices including smartphones, tablets and laptops at the same time. The voltage rating of this power bank is 220V, with which, as claimed, TVs, washing machines and electric induction cookers, pots etc. can be powered.<!–
