Ring battery cameras charge in two to four hours on average, depending on the model and charger you use
A Ring Video Doorbell 4 with the standard USB charger takes about two to three hours to go from empty to full. The Ring Video Doorbell Pro charges in roughly two hours. Older models like the Ring Video Doorbell 2 can take up to four hours. The time varies because newer models have larger batteries and faster charging circuits, but also because the charger itself matters — using a low-amperage charger or a computer USB port instead of a wall outlet will add an hour or more to the process.
The battery does not have to be completely dead before you charge it. You can top it up at any point, and a partial charge takes proportionally less time. Most people find it practical to charge their Ring camera once every few months during normal use, though this depends on how many motion events and video recordings happen at your door.
Key Takeaways
- Ring Video Doorbell 4 and Pro models charge in two to three hours with a standard USB charger plugged into a wall outlet.
- Older Ring models like the Video Doorbell 2 take up to four hours because the battery capacity is smaller but the charging speed is slower.
- Using a low-power charger, a computer USB port, or a portable battery pack will extend charging time by one to two hours.
- You do not need to wait for the battery to fully drain before charging — topping up a partially charged battery takes less time and is better for battery lifespan.
What charger comes in the box and what it delivers
Ring includes a USB-A to USB-C cable with most doorbell models, but the power adapter itself is not always included. If you have a wall outlet USB adapter rated for at least 2 amps, that works with the standard cable. The Ring Rapid Charger, sold separately, is rated for 2.4 amps and cuts charging time by roughly 30 minutes compared to a standard 1-amp adapter.
If you use a computer USB port or a portable phone charger, expect the full charge to take four to five hours instead of two to three. Phone chargers vary widely in output — some deliver only 1 amp, which is too slow for Ring batteries. Check the label on your charger. It should say at least 2 amps or 2000 mA.
Charging times by Ring model
| Model | Battery Capacity | Charge Time (Standard Charger) | Charge Time (Rapid Charger) |
|---|---|---|---|
| Ring Video Doorbell 4 | 5,200 mAh | 2–3 hours | 1.5–2 hours |
| Ring Video Doorbell Pro | 3,000 mAh | 2 hours | 1.5 hours |
| Ring Video Doorbell 2 | 4,800 mAh | 3–4 hours | 2–3 hours |
| Ring Stick Up Cam Battery | 2,600 mAh | 2–3 hours | 1.5–2 hours |
The Ring Video Doorbell Pro has the smallest battery but charges fastest because it was designed for faster charging circuits. The Video Doorbell 4 has a larger battery, so even though it charges at the same rate per amp-hour, the total time is longer. Older models like the Video Doorbell 2 charge more slowly overall.
Battery capacity is measured in milliamp-hours (mAh). A larger mAh number means more storage but also longer charging time, assuming the charger delivers the same power. The Pro model's smaller battery is one reason it finishes first, even though all models use the same USB-C connector.
How to know when your Ring camera is fully charged
The Ring app shows the battery percentage in the device settings. Open the Ring app, tap the device, go to Device Health, and look for the battery level. When it reads 100 percent, the camera is fully charged. Some Ring cameras also have a small LED light on the back that turns green when charging is complete, though not all models include this feature.
Do not rely on the cable feeling warm or the charger stopping the flow of power — USB charging circuits do not always signal completion clearly. Check the app instead. Once you see 100 percent, you can unplug the camera safely. Leaving it plugged in after that point does no harm, but unplugging it frees up the outlet.
Factors that slow down charging
Cold weather slows charging. If your Ring camera is below 50 degrees Fahrenheit, the charging process takes longer and may not reach 100 percent until the battery warms up. This is normal and does not damage the battery. Bring the camera indoors or wait for warmer weather.
A damaged or worn cable also extends charging time. If the cable has visible cracks, fraying, or bent connectors, the connection may be loose and the charger may deliver less power. Replace the cable with a new USB-A to USB-C cable rated for at least 2 amps.
Using the camera while it charges slows the process. If motion events trigger video recording or if you are streaming live view, the battery is discharging at the same time it is charging. Unplug the camera or turn off motion detection while charging if you want the fastest charge time.
How often you need to charge and what affects it
Most Ring doorbell owners charge their cameras once every two to four months during normal use. A busy front door with frequent motion events and video recordings will drain the battery faster and require charging every four to eight weeks. A quiet door may go six months or longer between charges.
Cold weather also drains the battery faster. In winter, expect to charge more often — sometimes every four to six weeks instead of every three months. This is because the battery delivers less power in cold temperatures, and the camera may work harder to maintain a connection. You can extend the time between charges by lowering the motion detection sensitivity, reducing the video resolution, or disabling features like person detection through the Ring app.
What to do if your Ring camera will not charge
First, check that the cable is fully inserted into both the camera and the power adapter. The USB-C connector on Ring cameras is tight by design, so push firmly until you feel it click. If it still does not charge, try a different USB cable and power adapter to rule out a faulty charger.
If the camera charges with a different cable but not the original one, the original cable is damaged and needs replacement. If it does not charge with any cable, the battery itself may be defective. Ring offers a one-year warranty on batteries, so contact Ring support with your proof of purchase. Do not attempt to open the camera or replace the battery yourself — Ring batteries are sealed inside the device and are not user-replaceable. Opening the camera will void the warranty and may damage the electronics.
Frequently Asked Questions
Can I use my phone charger to charge my Ring camera?
Yes, if it is a USB-A to USB-C charger rated for at least 2 amps. Many phone chargers deliver only 1 amp, which will charge your Ring camera but take four to five hours instead of two to three. Check the label on your charger before plugging in your camera.
Is it bad to leave my Ring camera plugged in overnight?
No. Once the battery reaches 100 percent, the charger stops delivering power and the camera is safe to leave plugged in. Modern USB chargers have built-in protection that prevents overcharging. You can leave your Ring camera on the charger indefinitely without damage.
Why does my Ring camera charge slower in winter?
Cold temperatures reduce the chemical reaction inside the battery, slowing the charging process. This is temporary and does not damage the battery. Bring the camera indoors to room temperature and it will charge at normal speed again.
Do I need the Ring Rapid Charger, or is the standard charger fine?
The standard charger works fine for most people. The Rapid Charger saves 30 to 45 minutes per charge, which matters if you need your camera back online quickly. If you charge infrequently and do not mind waiting a few hours, the standard charger is sufficient.
What happens if I use a charger with more than 2 amps?
Ring cameras are designed to accept up to 2.4 amps safely. Using a charger rated for 3 amps or higher will not damage the camera — the charging circuit will only draw what it needs. You will not see faster charging times beyond 2.4 amps.
