Is the patent of manual charging treasure valuable?

Is credible. There are two things in a charging treasure, one is a control chip and the other is a battery. Batteries are cheap and chips are expensive. You need to buy fast charging patents from various companies, and you have to pay with special chips and protocols. The miscellaneous charging treasure does not support fast charging, so you don't have to spend money to buy a patent. Naturally cheap, the disadvantage is slow charging.
