You can tell by looking at the chip that it is roughly 9~18V input, 2A charging, 1.5A balanced heating is a bit large, it is recommended to reduce the current or enhance heat dissipation. This is mainly because at the end of July, I remembered that there was a unit of 5 yuan. It’s useless so I just want to draw something (question) As for why it was only released in September, it’s because of the quarantine.
