Original D-Type USB Charge Data Cable for Checkme O2 Max, SleepU, VisualOxy, Oxiband Ring Pulse Oximeter, BabyO2, BabyO2 S2

This USBC was bought to charge my Checkme O2 Max, and it did exactly what it’s supposed to - no fuss, no drama. Plugged it in, and boom, my device powered up in no time. Solid connection, reliable performance, and now my O2 Max is back in action.

Works Perfectly with my Wellue Checkme 02 Pulse Oximeter! It charged it right up!

This cable is so much better than the piece of junk that comes with the SleepU. Those typically fail after less than a year. The USB side on this cable is a nicely bonded piece that feels just like any other quality USB device would have.Thank you for this!

I received an error 4 for the original sensor with less than three months use. Wellue customer service responded and sent me a replacement sensor.

If I could hve waited a couple of weeks could have purchased for half the price. Cable is short but it did work for my Pulsebit EX device.

This cord actually has a chip in it to communicate with your device.MARK THE CORD so you can identify it later, and don't lose it.[The chip is a UART btw]

I have been using Viatom/Wellue pulse oxymeters for many years. The SleepU is the best for when I sleep at night. But, the actual sensor and the data/power cables tend to get loose or stop working for data after a year or two. Fortunately, I discovered that it is possible to replace the sensors.When my data/power cable stopped working reliably (the desktop app not recognizing it), I checked Amazon to see if there might be a replacement. And found this and am very, very happy.It is much less expensive to replace the sensor and data/power cable to to buy a whole new unit (which I have done in the past).

I got this charger because it was the size advertized to fit my pulse oximeter. It did not fit my device, so I have not been able to judge how well it charges. It does appear well made.
