2Pcs USB Charging Cable, Portable Magnetic Smart Watch Charger Charging Station Dock Replacement Charging Cable for 4.0mm 2-Pin Devices Black

For athletes who use the Core heat sensor to track body temperature and performance. The original white USB charging cord can wear out and this is a compatible option with the 4mm spacing that works the same as the OEM white USB charging cord. Recommend if you are having trouble charging your Core sensor and the metal pins that move and have springs behind them aren't working well anymore. In the pictures you can see the comparison between the two, they are identical other than color. Note, my Core sensor is glued to the back of a Garmin GoPro mount since the original plastic tabs broke off (common issue with the Core sensor design).

I needed a couple of extra charging cords for my Catshin S61 smartwatch, but found it difficult to find anything online related to that particular watch. I wanted a cable for my car and one for travel.The description for this item gave the measurement distance between contact pins, so I measured the distance on the original charge cord that came with the watch. "Perfect match".Works fine.

Simple to use but only works from one side. This makes it easy to disconnect at it tends to slide off the charging pads on the watch too easily. As long as you set it and don't move it then it charges just fine. Bought these for a replacement for my smart watch.

Couldn’t believe I lost my watch charger again. The last time I just bought a new watch. Wasn’t doing that. This did the trick. Even came with a spare. Works great. Now that’s smart!!

Had to return. Between you and Baby Valley (another manufacturer, I haven't gotten one that works. nOw I don't know which 2 are from you or Baby Valley.

Did not fit even though it was suppose to fit their brand, Amazfit watches.

The cord did not fit my watch. I have to buy a new watch just to get the correct cord. ☹️

Works exactly as described, no problems. Easy to use.
