Review on 🔌 High-Quality 16.4FT Long Power Extension Cable for Wyze Cam, YI Camera, NestCam, Netvue, KasaCam, Furbo Dog, Blink, Amazon Cloud Cam - Micro USB Charger Charging Cord for WyzeCam v3 v2 Security Camera by Joe Fulce

If you need a long micro cable to charge your phone, look elsewhere. Although rated for fast charging at 2.1A, it actually supplies less than 1A when connected to smartphones (some smartphones will give a warning/notice). Check the cable connections as the power received is too low.) My smartphone shows less than 1.5 hours to fully charge with 2.1A, about 2.5 hours with 1A, but about 5 hours with this cable. And if you use a phone, no charges are added!
