![]() ![]() With a little adjustment to get it to sit on the pins properly, it works, drawing about 180mA at 5V. How do I charge my Fitbit device Plug the charging cable that came with your Fitbit device into a USB port on your computer, a UL-certified USB wall charger, or another low-energy device. I limited the power supply to 300mA and gave it a shot. Only one Premium membership + 2-year protection plan (the 'Bundle') per customer and for new and returning Premium members only. This gives you time to disconnect it before anything gets too warm.) ![]() With the current limiting, the supply will back off on the voltage if too much current is flowing. (The current-limited part is important: if you get the polarity wrong and forward-bias a protection diode, you don’t want your power supply dumping three amps of current through it. It is estimated that 85 of EV charging takes place at home or at work, so many EV drivers rarely use public charging. So I hacked together a small breadboard-based adapter and connected it to a current-limited lab power supply. Find a public charging station in your area. If I were designing a watch like this, I’d go for one 5V pin in the center and two ground pins. ![]() This, with the fact that the charging cables don’t look like they contain more than just wires, means that, in all likelihood, either the center pin is ground and the outer pins are 5V, or the other way around. So the two outside pins must have the same function. I knew that the charging connector was symmetric it will work in either orientation. The three gold pins are for the charging cable. ![]()
