Review on 🔌 AWINNER Charger for Fitbit Charge 4 - USB Charger Adapter Cord Charging Cable for Fitbit Charge 4 Heart Rate Fitness Wristband (2-Pack) - Compatible & Reliable by Ann Coleman

I lost my original charger on vacation and had it delivered to my girlfriend's house. They arrived quickly and look just like the original Fitbit charger. Unfortunately, they either don't work or work very poorly. My Fitbit showed "not charging" on both devices. In fact, it charged just so slowly that it was invisible. I plugged one in at night for 6 hours and transferred the charge from 15% to 40%. With the original charger, a full charge takes about an hour. The device was just as slow. It did the job (barely) until I got home and replaced it with an original Fitbit charger. Mui small.
