While Chinese electronics manufacturers are trying in vain to increase the autonomy of portable devices, one person has done the impossible.
Every year, power banks are getting bigger and more powerful – 5,000 mAh, 10,000 mAh and even 20,000 mAh. This is enough to stay in touch on long hikes, and help not only yourself, but also your friends. But one Chinese blogger was indignant when he realized that his friends had cooler and bigger power banks. In the end, he decided to go for broke – to create a huge external battery on 27,000,000 mAh.
For such power, the Chinese needed a battery from an electric car. He had to be fenced off from the outside world with metal plates. As a result, such a power bank is capable of delivering electricity up to 220 watts. At the same time, this battery supplies up to 20 devices, among them can be both typical smartphones and a TV with a washing machine. Unfortunately, due to its size and weight, the power bank can hardly be called portable.
