I have quite a few Bosch Pro 18V batteries that I would like to use as a USB power bank. In my opinion, the official Bosch GAA 18V-48 is outdated as it only has USB-A ports and a 5V output. Ideally, I would also like the option of charging the battery via USB-C.

Although there are several different USB adapters available on AliExpress and Amazon, I don't trust them, and I can't find much information or test results elsewhere. Does anyone have experience with AliExpress USB-C adapters and can recommend one?
