2-Pack AB284 Reversible Smart Watch Charger – Innovative Magnetic Charging Cable, Solves Polarity Mismatch, Universal for All 2.84mm-Pin-Pitch Devices: Select Bone Conduction & Open-Ear Headphones

Fast charging. Fit well and good price 👍

Great quality and pricing.

This one actually charged my watch! After trying 2 other brands, this one actually worked!

Was able to charge my smart phone that zi needed to check my glucose level when I was traveling to Europe recently . The previous charger had been broken and I could not find a replacement charger until this one .

Could get it work. There were two that were supposedly interchangeable. Not. Next.

As expected

These are good cables and the polarity can be reversed to work on different watches, i would buy again

I got two off-brand smart watches from different companies. The charging connections both look the same, but when I lost the cable for one watch the other watch's cable didn't work on it. I bought a new cable that also didn't work, but then managed to track down the company and get a cable from them - that looked the same as the others - and it does work. I didn't realize the issue was polarity until I saw these cables, so I immediately got them for backups.And they're perfect! For the watch I currently wear I need to plug into the B side, and the other watch charges when I'm plugged into the A side, so I just use a different cable for each one, but if I lost a cable I could still charge both watches because you can choose A or B on each one.I'm so glad I came across these! Brilliant idea, and they work great.I like longer cords, but at least these are the short little 6" ones; the length hasn't been a problem so far.Thank you for reading, I hope it was helpful.
