Ring battery doorbells charge in 5 to 10 hours on a standard USB outlet

A fully drained Ring battery doorbell takes between 5 and 10 hours to reach full charge when plugged into a standard USB power adapter. The exact time depends on which Ring model you own, the power output of your charger, and whether the device is in use while charging. Ring's newer models like the Ring Video Doorbell (2024) and Ring Video Doorbell Pro charge faster than older generations.

The charging cable that comes in the box is a USB-C or micro-USB cord, depending on your model. You'll need a USB power adapter rated at least 2 amps to charge at the normal speed. Using a lower-power charger — like a phone charger rated at 1 amp — will extend the charging time to 12 hours or longer.

You don't have to wait for a complete charge before using the doorbell again. Ring devices will power on and function once they reach about 20 percent battery, though they'll drain quickly if you're actively using the video or two-way talk features while still plugged in.

Key Takeaways

  • Most Ring battery doorbells charge fully in 5 to 10 hours using a standard 2-amp USB power adapter.
  • The charging time varies by model — Ring Video Doorbell (2024) charges faster than Ring Video Doorbell 3 or earlier versions.
  • A low-power charger rated below 2 amps will add several hours to the charging time.
  • Your doorbell will power on and work at 20 percent battery, but will drain faster if you use video or talk features while charging.

Charging times for specific Ring models

Ring Video Doorbell (2024) charges in approximately 5 to 6 hours with a 2-amp adapter. This is the fastest Ring battery model currently sold.

Ring Video Doorbell Pro takes 6 to 8 hours to charge fully. It uses USB-C and benefits from higher-power adapters — a 3-amp charger will charge it slightly faster than a 2-amp charger.

Ring Video Doorbell 3 and Ring Video Doorbell 3 Plus charge in 8 to 10 hours. These older models have larger batteries relative to their charging circuitry, so they take longer than newer versions.

Ring Video Doorbell 2 and earlier models charge in 10 to 12 hours. If you own one of these, upgrading to a newer model will cut charging time roughly in half.

What affects charging speed

The power rating of your USB adapter is the biggest factor. Ring recommends a minimum of 2 amps. Most phone chargers sold today are 2 amps or higher, but older chargers and cheap third-party adapters may be rated at 1 amp. Plugging into a 1-amp charger will add 3 to 5 hours to the total charging time.

The USB cable itself matters less, but a damaged or low-quality cable can slow charging. If your doorbell charges unusually slowly, try a different USB cable before assuming the device is faulty.

Using the doorbell while it charges will slow the process. If you're actively watching video, talking through the speaker, or triggering motion detection, the battery drains faster than it charges. Plug it in during a time when you expect less activity, or charge it indoors away from motion triggers.

Ambient temperature affects charging speed slightly. Charging in a cold garage or outdoor shed may add 1 to 2 hours. Ring batteries charge most efficiently between 50 and 95 degrees Fahrenheit.

How to charge your Ring doorbell

Remove the doorbell from its mounting bracket by pressing the release button on the bottom and sliding it downward. The USB port is on the bottom of the device. Connect the USB-C or micro-USB cable (whichever matches your model) to the port and plug the other end into a power adapter.

A small LED light on the doorbell will turn on when charging begins. The light will change color or turn off when the battery reaches full charge — the exact behavior depends on your model, so check your manual if you're unsure what to expect.

Leave the doorbell unplugged for at least 30 minutes after it finishes charging before reinstalling it. This allows the battery to stabilize and prevents charging errors on your next cycle.

Charging cables and adapters to use

Ring includes a USB cable in the box, but you'll need to provide your own power adapter. Any USB power adapter rated 2 amps or higher will work. Common options include phone chargers, tablet chargers, or dedicated USB power supplies.

If you've lost the original cable, replacement USB-C and micro-USB cables are inexpensive and widely available. You don't need a Ring-branded cable — any standard cable of the correct type will charge your doorbell at the same speed.

Avoid using a computer USB port to charge your doorbell. Most computer ports supply only 0.5 amps, which will charge your device very slowly or not at all. Always use a wall-mounted power adapter.

What to do if your Ring doorbell won't charge

First, check that the USB port is clean and free of debris. Dust or lint can block the connection. Use a dry cloth or a soft brush to gently clean the port, then try charging again.

Try a different USB cable. The original cable may be damaged even if it looks fine. If charging works with a different cable, replace the original one.

Test with a different power adapter rated 2 amps or higher. If your doorbell charges with a different adapter, the original adapter may be faulty or underpowered.

If the doorbell still won't charge after trying different cables and adapters, the battery or charging circuit may be defective. Contact Ring support with your purchase date and model number — most devices are covered by a one-year warranty that includes battery defects.

How often you need to charge

Most Ring battery doorbells need charging every 2 to 6 months, depending on how much activity your doorbell sees. A doorbell in a low-traffic area might go 6 months between charges. A doorbell that records 20 or more motion events per day will need charging every 2 to 3 months.

You can check your battery level anytime in the Ring app. Open the app, tap the device, and look for the battery percentage in the device settings. Set a phone reminder when the battery drops below 30 percent so you don't forget to charge it.

Some Ring owners charge their doorbells on a fixed schedule — for example, every 3 months — rather than waiting for the battery to run low. This approach prevents the doorbell from dying unexpectedly and keeps the battery in good health over time.

Frequently Asked Questions

Can I charge my Ring doorbell while it's still mounted on the wall?

No. You must remove the doorbell from its bracket to access the USB port on the bottom. The bracket covers the port completely. Removal takes about 30 seconds — press the release button and slide the device downward.

What happens if I use a charger with more than 2 amps?

Ring doorbells can safely charge with adapters rated up to 3 amps or higher. A higher-power charger will not damage the battery. Charging may be slightly faster with a 3-amp adapter compared to a 2-amp adapter, but the difference is usually only 30 minutes to 1 hour.

Does my Ring doorbell charge faster if I turn it off while plugged in?

Turning off the doorbell won't significantly speed up charging. The device draws very little power when idle. The main factor is the power adapter you're using. If charging feels slow, check that your adapter is rated 2 amps or higher.

Can I charge my Ring doorbell with a wireless charger?

No. Ring doorbells do not support wireless charging. They charge only through the USB port on the bottom of the device using a wired cable and power adapter.

Is it bad to leave my Ring doorbell plugged in after it's fully charged?

Leaving it plugged in for a few hours after it reaches full charge is harmless. However, don't leave it plugged in continuously for days or weeks. Unplug it within a few hours of the charge cycle ending to keep the battery healthy over time.
