A:AnswerI would use the original orange USB that Ring provides with each doorbell. It’s a flat android looking charger. For me, it works best and charges really fast. Not sure about voltage levels.
A:AnswerHad my spare charged for 2 weeks and it had 100% when I changed it out. That, by the way, is how long it took the original one to get down to 13%
A:AnswerJust an update, I did buy this and the battery DOES charge within the device. When power is cut to the ring cam, the battery kicks in. When hard wired power is then supplied back to the camera, the battery DOES actually charge within the camera and is back to 100% once the power is cut to the ring cam again
A:AnswerHello La,
During charging both the red and green lights will light up. Your battery is fully charged when the light on the battery shines a solid green.
