Ring doorbells charge through a wired connection, not by removing the battery
Unlike some smart devices, you cannot take the battery out of a Ring doorbell and charge it separately. Instead, you charge the doorbell in place by connecting it to your home's existing doorbell wiring or to a power adapter. The battery inside stays put and charges while the device remains mounted on your door frame.
Ring doorbells come in two main types: wired models that connect to your home's 16-24 volt doorbell transformer, and battery-only models like the Ring Video Doorbell (Battery) that charge through a USB cable. Knowing which type you have determines how you charge it.
Key Takeaways
- Wired Ring doorbells charge automatically when connected to your home's existing doorbell transformer, with no action needed on your part.
- Battery-only Ring models charge through a USB-C or micro-USB cable connected to a power outlet, taking 4 to 6 hours for a full charge.
- A low battery warning appears in the Ring app when your doorbell drops below 20 percent, giving you time to charge before it shuts down.
- If your home has no existing doorbell wiring, you can use a plug-in transformer to power a wired Ring model instead of buying a battery-only version.
Charging a wired Ring doorbell through your home's transformer
If your Ring doorbell is wired to your home's existing doorbell transformer, charging happens automatically. The transformer converts your home's electrical current to the low voltage the doorbell needs, and the battery charges continuously while the device is powered on. You do not need to do anything — the battery charges as long as the wiring is connected and working.
To confirm your doorbell is wired correctly, open the Ring app and go to Device Health. If the Power Source shows "Wired," your doorbell is drawing power from the transformer. If it shows "Battery," your doorbell is running on battery power alone and will eventually drain.
If you recently installed a wired Ring doorbell and the app still shows "Battery," check that the wires are fully connected to the transformer terminals and that the transformer itself is powered on. Some older transformers have an on/off switch; others are always active. If the transformer is dead or disconnected, the doorbell will not charge.
Charging a battery-only Ring doorbell with a USB cable
Battery-only Ring models like the Ring Video Doorbell (Battery) and Ring Video Doorbell Plus (Battery) charge through a USB cable. You will need to remove the doorbell from its mounting bracket, connect the USB cable to the charging port on the back, and plug the other end into a power outlet or USB power adapter.
Most Ring battery doorbells use USB-C, though some older models use micro-USB. Check your device manual or the Ring app to confirm which port your model has. A standard USB power adapter rated for at least 2 amps works fine; the same adapter you use for a phone or tablet will work.
A full charge takes 4 to 6 hours depending on how depleted the battery is. The Ring app does not show a charging progress bar, so you will not know exactly when it is done. A safe approach is to charge overnight or for at least 6 hours before remounting the doorbell.
Understanding low battery warnings and how long the battery lasts
The Ring app sends a notification when your doorbell battery drops below 20 percent. This warning gives you time to charge before the battery runs completely empty. If you ignore the warning, the doorbell will eventually power off and stop recording video or detecting motion.
How long a full charge lasts depends on how often your doorbell detects motion and records video. In a quiet neighborhood where the doorbell records a few times per day, a battery may last 6 to 12 months. In a busy area with frequent deliveries or foot traffic, the battery may drain in 2 to 4 months. Cold weather also drains batteries faster than warm weather.
If your battery drains much faster than expected, check the Ring app for a list of recent events. If the doorbell is recording constantly or detecting motion every few minutes, something may be triggering it repeatedly — a tree branch moving in the wind, a pet, or a motion detection zone set too wide. Adjusting the motion zones in the app can extend battery life significantly.
Using a plug-in transformer if you have no existing doorbell wiring
If your home has no doorbell wiring and you want a wired Ring model instead of a battery-only one, you can buy a plug-in transformer. This device converts standard 120-volt household current to the 16-24 volts a Ring doorbell needs. You plug it into an outlet near your door, run wires from the transformer to the Ring doorbell, and the doorbell charges continuously just like a traditionally wired model.
Ring sells an official plug-in transformer, or you can buy a generic 16-24 volt transformer from an electronics supplier. The transformer must be rated for at least 40 VA (volt-amps) to power a Ring doorbell reliably. Installation involves running low-voltage wire through your door frame or along the outside of your house, which takes an hour or two depending on your home's layout.
This approach costs more upfront than a battery-only model but eliminates the need to charge the doorbell every few months. It also provides more reliable power for features like continuous video recording and two-way talk, which drain batteries quickly.
Troubleshooting a Ring doorbell that will not charge
If your wired Ring doorbell is not charging, first check that the transformer is powered on and that the wires are fully seated in the terminal screws. Loose connections are the most common reason a wired doorbell stops charging. Turn off the transformer, loosen the terminal screws slightly, reinsert the wires, and tighten the screws firmly. Then turn the transformer back on and wait 10 minutes for the doorbell to recognize the power.
If your battery-only doorbell will not charge, try a different USB cable and power adapter. A damaged cable or a weak power adapter can prevent charging even if the port looks fine. If the doorbell still will not charge after trying a different cable, the charging port or internal battery may be damaged. Contact Ring support for a replacement.
For wired doorbells, you can also check the transformer itself. If the transformer has a light or indicator, make sure it is on. If it has no indicator, plug a lamp into the same outlet to confirm the outlet has power. If the outlet is dead, the transformer is not receiving power and cannot charge the doorbell.
Frequently Asked Questions
Can I charge my Ring doorbell while it is still mounted on the door?
No, battery-only models must be removed from the mounting bracket to access the charging port. Wired models charge automatically while mounted, so you never need to remove them. If you have a battery-only model, you will need to unmount it, charge it indoors, and remount it when done.
What happens if my Ring doorbell battery dies completely?
The doorbell will stop recording video, detecting motion, and responding to button presses. It will not restart or charge itself. You must manually charge it through a USB cable or reconnect it to a working transformer. Once charged or powered, it will come back online within a few minutes.
Do I need a special charger for my Ring doorbell?
No. Battery-only models charge through any standard USB power adapter rated for at least 2 amps — the same type used for phones and tablets. Wired models do not need a separate charger; they charge through your home's existing doorbell transformer or a plug-in transformer you purchase separately.
How often should I charge my Ring doorbell battery?
Charge when the Ring app sends a low battery warning, typically when the battery drops below 20 percent. Depending on activity, this may happen every 2 to 12 months. Some users charge proactively every 6 months to avoid running out of power during heavy use periods like holidays.
Can I use a fast charger on my Ring doorbell?
Yes, Ring doorbells can handle fast chargers. A USB-C fast charger rated for 30 watts or higher will not damage the doorbell, though it will not charge significantly faster than a standard 2-amp adapter. The doorbell's internal charging circuit limits how quickly the battery accepts power.
