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

Great item it really works! Fast shipping item was as described.

Basically...this is the one to buy...I tried two different brands and they were of the same + and - configuration that didn't work. After searching for a while I found this charging cord that has "reversible poles"....what a since of relief that I found a company that thought "out of the box", and made a product that worked with any off-brand watch....you do need to measure the distance between the connectors....AWSOME product

Definitely works with all smart watches

The magnet connection is strong and charges with no issuesm

Bought this for my smartwatch, which when I verified the watch stated it was the same dimensions I needed, so I purchased this dual pack charging cable, it didn't work, the magnets were so weak it couldn't even hold onto the back of my watch to charge it, then to even get the watch to verify it was charging I had to press down practically with the strength of Superman and slightly move it around until it made contact and showed the lightning bolt charging icon on the watch face. But as soon as I let go with the very slightest release of pressure, the watch went blank, nothing. These magnetic watch charging cables are completely worthless, can't even do what they were designed for, to simply hold the cable onto the watch and charge it, but the magnets, again, are so weak they wouldn't even stay out, just fell off when trying to charge my watch. Nope, don't buy these magnetic smartwatch charging cables, they won't stay attached, and they'll only charge if you hold them in place with a lot of downward force. And who's going to do that for 3 to 6 hours to charge their watch....no one I know. If I could have given ZERO★'s I would have. Absolutely DO NOT RECOMMEND THESE TO ANYONE!

Did research and tried two other brands of charging cables and they did not work. Probably due to polarity issues. These cables allow you change polarity and they worked on my watch. Highly recommend. Be sure to order the correct pin size (distance between pins: e.g . 4 mm)

Works well. Coordinates well with watch

Appears to be of good quality. So far it works as it should. The fact that the polarity can be reversed is a nice feature that makes it well worth the money.
