Charging time depends on which Ring doorbell you own and how you charge it

A Ring doorbell battery takes between 5 and 10 hours to charge fully, depending on the model. The original Ring Video Doorbell and Ring Video Doorbell 2 charge in about 5 to 10 hours using the included USB cable and power adapter. Newer models like the Ring Video Doorbell (3rd generation) and Ring Video Doorbell Pro charge in roughly the same window. The Ring Video Doorbell Pro 2, released more recently, also falls into this 5 to 10 hour range.

The actual time varies based on three factors: which charger you use, the battery's current charge level, and the model's battery capacity. Using the official Ring USB power adapter gets you the fastest charge. Using a different USB adapter or a computer's USB port will charge more slowly — sometimes taking 12 to 24 hours or longer. Starting from completely dead versus partially drained also matters; a battery at 20 percent charge reaches full faster than one at zero.

Key Takeaways

  • Most Ring doorbells charge fully in 5 to 10 hours using the official USB power adapter that comes in the box.
  • Using a different USB charger or a computer's USB port can double or triple the charging time.
  • The battery charges faster if it is not completely drained, so you do not have to wait for it to hit zero before plugging it in.
  • You can still use your Ring doorbell while it charges, though the battery will charge more slowly if the device is actively recording or streaming.

Using the official Ring USB power adapter

The fastest way to charge is with the USB power adapter that comes in the Ring doorbell box. Plug the adapter into a standard wall outlet, connect the USB cable to your doorbell's charging port, and the battery will reach full charge in 5 to 10 hours. The exact time depends on your specific model — check your doorbell's manual or the Ring app to confirm which model you own.

The official adapter delivers the correct voltage and current for your doorbell's battery. Using it means you are not guessing whether a third-party charger will work safely or at the right speed. If you have lost the original adapter, Ring sells replacements on their website, though they cost between $15 and $25 depending on your model.

Why third-party chargers take longer

If you use a different USB power adapter — one from a phone, tablet, or computer — charging will be noticeably slower. A standard computer USB port delivers less power than a wall outlet, and some third-party adapters deliver even less. This can stretch charging time to 12, 18, or even 24 hours. The battery will still charge, but the slower current means it takes much longer to reach 100 percent.

A low-power charger does not damage the battery, but it defeats the purpose of having a quick charge window. If you are without the original adapter temporarily, a phone charger rated for at least 2 amps will work faster than a computer port. Check the adapter's label — it will say something like "2A" or "2000mA" to show the current it delivers.

Charging while your doorbell is in use

You can leave your Ring doorbell plugged in and still use it normally — it will record video, send notifications, and stream live view while charging. However, the battery charges more slowly when the doorbell is actively working. If someone rings the bell or you open the live view in the Ring app, the device draws power for that activity, leaving less power available for charging the battery itself.

For the fastest charge, plug in the doorbell during a time when you expect fewer visitors or when you can temporarily disable notifications. If you live on a busy street or expect deliveries, you may want to charge overnight when activity is lower. The doorbell will still charge during the day — it just will not reach 100 percent as quickly.

What to do if charging seems stuck or very slow

If your Ring doorbell has not charged noticeably after 12 hours with the official adapter, check three things. First, make sure the USB cable is fully inserted into both the power adapter and the doorbell's charging port — a loose connection will prevent charging. Second, look at the charging port on the doorbell itself for dirt, lint, or corrosion. Gently clean it with a dry cloth or a dry cotton swab if you see buildup.

Third, check the Ring app to see the battery percentage. Open the app, go to your doorbell's settings, and look for the battery level. If it is stuck at the same percentage after several hours, the battery itself may be failing. Ring batteries typically last 2 to 3 years before they stop holding a charge properly. If the battery is older than that or will not charge past a certain point, you may need to replace it. Ring sells replacement batteries for most models, and they cost between $20 and $40.

Checking your battery percentage in the Ring app

You do not have to guess whether your doorbell is fully charged. The Ring app shows the exact battery percentage at any time. Open the Ring app on your phone, tap the menu icon (three horizontal lines), select your doorbell from the device list, and tap "Device Health." The battery percentage appears near the top of the screen.

Check this percentage before you unplug the charger. If it shows 100 percent, the battery is fully charged and you can disconnect the USB cable. If it shows less than 100 percent after 10 hours with the official adapter, something may be wrong — either the charger is not working, the cable is loose, or the battery needs replacement. The app also shows you when the battery was last charged, which helps you track whether the charge is lasting as long as it should between charges.

How often you will need to charge

How long a full charge lasts depends on how much your doorbell is used. A doorbell in a quiet area with few visitors and no motion detection events may go 2 to 3 months on a single charge. A doorbell on a busy street or in a home with frequent motion alerts may need charging every 3 to 6 weeks. Heavy use — lots of video recording, live view streaming, or motion events — drains the battery faster.

The Ring app will send you a notification when the battery drops below 20 percent, giving you time to charge before it dies completely. You do not have to wait for that warning to plug it in. Many people charge their doorbell every month or every other month as part of routine maintenance, rather than waiting for a low battery alert. This keeps the battery healthier over time and ensures your doorbell is always ready.

Frequently Asked Questions

Can I charge my Ring doorbell with a phone charger?

Yes, but it will charge much more slowly. A phone charger rated for 2 amps or higher will work faster than a computer USB port, but the official Ring adapter is still your best option. If you use a phone charger, expect charging to take 12 to 24 hours instead of 5 to 10.

Does my Ring doorbell have to be unplugged to charge the battery?

No. Your Ring doorbell is always powered by the wired connection to your home's electrical system. The battery is a backup that powers the doorbell if the wired connection fails. You charge the battery by plugging in the USB cable while the doorbell is still mounted and wired.

Why is my Ring doorbell battery draining so fast?

Heavy use drains the battery quickly — lots of motion detection, live view streaming, or video recording all consume power. Cold weather also reduces battery life. If the battery drains much faster than it used to, it may be aging and losing capacity. Batteries typically last 2 to 3 years before they need replacement.

What happens if my Ring doorbell battery dies completely?

If the battery dies, the doorbell stops working until you charge it. The wired connection alone is not enough to power the device — the battery is required. Plug in the USB cable and wait 5 to 10 hours for a full charge, then the doorbell will work again.

Is it bad to leave my Ring doorbell plugged in all the time?

No. Lithium batteries like the one in your Ring doorbell are designed to handle constant charging. Leaving it plugged in will not damage the battery or shorten its lifespan. Once the battery reaches 100 percent, the charger stops delivering power, so there is no risk of overcharging.
