Ability to recharge varies based on device settings, usage, and sun exposure in the area of placement. Stay charged longer by connecting this USB-C Solar Panel to any Ring USB-C Security Camera—or barrel-plug camera with the included USB-C to barrel plug adapter. Mount horizontally, then use the adjustable arm with 180 degrees of tilt to get the perfect angle to maximise your solar power. For best performance, Ring recommends at least 2-3 hours of direct sunlight per day.
