In the year+ since this thread started, I've been on a quest to rid my life of micro USB stuff and move to USB-C. I've lost count of the devices with failed micro USB ports, yet I've never had a USB-C failure; it's a far superior standard, plus on more advanced devices it allows for much faster PD charging.
Anyhoo, it can be surprisingly difficult to determine what kind of port or charging standard a rechargeable device uses. More and more are finally starting to use and specify USB-C and PD fast charging.
Most recently, I needed a small rechargeable cranium-mounted light to carry on my motorcycles, and after several micro USB dead ends I ended up with a "Smiling Shark" brand light.
The light is cheap, works great, and at least "Smiling Shark" is pronounceable and comprehensible by English speakers.
