Ring battery devices charge in 5 to 10 hours from empty, depending on the model and charger

A Ring Video Doorbell 4 with the standard USB charger takes about 5 to 10 hours to go from completely dead to fully charged. The Ring Stick Up Cam and Ring Indoor Cam take roughly the same time. If you use a faster charger — one that delivers more power — you can shorten that window, though Ring does not officially rate faster charging times.

The actual time depends on three things: which Ring device you own, whether you use the included charger or a different one, and how much battery is already in the device when you start. A device at 20 percent battery charges faster than one at zero percent, because the charging rate slows as the battery fills up.

Ring does not publish exact charge times for every model, so the 5 to 10 hour range is what most owners report. Some devices charge slightly faster or slower depending on the charger wattage and the device's internal battery size.

Key Takeaways

  • Ring battery doorbells and cameras charge in 5 to 10 hours using the standard USB charger that comes in the box.
  • Charging time varies by device model — the Video Doorbell 4, Stick Up Cam, and Indoor Cam all have slightly different battery capacities.
  • A faster USB charger (one rated for higher wattage) can reduce charging time, though Ring does not officially support or rate faster charging.
  • The device charges slower as the battery fills up, so the last 20 percent takes longer than the first 20 percent.

What charger comes with your Ring device

Ring includes a USB charger with most battery-powered devices. For the Video Doorbell 4, you get a USB-C to USB-A cable and a power adapter rated for 2 amps. For the Stick Up Cam and Indoor Cam, the included charger is usually a micro-USB cable with a similar power rating.

The charger that comes in the box is designed to work with that specific device. Using a charger with a lower power rating (fewer amps) will charge the device more slowly. Using a charger with a higher power rating will not damage the device, but Ring does not test or may provide faster charging with third-party chargers.

If you lose the original charger, you can use any USB charger you have at home, as long as it has the right connector type (USB-C or micro-USB, depending on your model). The device will charge, but it may take longer if the charger is underpowered.

How battery percentage affects charging speed

Ring devices charge fastest when the battery is nearly empty. As the battery fills up, the charging rate slows down. This is normal behavior for lithium-ion batteries — the type used in Ring devices, phones, and laptops.

The slowdown happens because the device protects the battery from damage by reducing the current as it approaches full charge. Going from 0 to 50 percent might take 3 hours, but going from 50 to 100 percent might take another 5 to 7 hours. This is why the last bit of charging always feels slow.

If you need the device back in service quickly, you do not have to wait for a full charge. Most Ring devices will work at 50 or 60 percent battery, though they will drain faster than if fully charged.

Charging time for different Ring models

Ring makes several battery-powered models, and they do not all charge at the same speed. The Video Doorbell 4 has a larger battery than the Video Doorbell 2, so it takes slightly longer to charge. The Stick Up Cam comes in wired and battery versions — only the battery version needs charging, and it takes about 5 to 10 hours.

The Ring Indoor Cam is smaller and charges faster than outdoor models, usually in the 5 to 8 hour range. The Ring Floodlight Cam Wired Plus does not have a battery, so it does not charge — it plugs into your home's electrical system.

Ring does not publish exact charge times for each model on their website, so the best way to know your device's specific time is to check the manual that came with it or contact Ring support with your model number.

Tips to charge your Ring device faster

Use the charger that came in the box first. It is designed for your device and will charge it at the intended speed. If you want to try a faster charger, look for one rated for at least 2 amps at 5 volts (written as 2A, 5V, or 10W). Higher wattage chargers are common — most phone chargers are 18W or higher — and will not harm the device, but Ring does not officially support them.

Keep the device cool while charging. If the device gets hot, it may slow down the charging rate as a safety measure. Charge in a room-temperature area, not in direct sunlight or next to a heat source.

Charge when the battery is not in use. Charging a device while it is actively recording or sending video will take much longer because the battery is draining at the same time it is charging. Disconnect the device from power or turn off recording before you charge it.

When to charge your Ring device

Ring recommends charging your device when the battery drops to 20 to 30 percent. You do not have to wait until it is completely dead. Charging from 30 percent to 100 percent takes less time than charging from zero, and it is better for the battery's long-term health.

Most Ring devices send you a notification when the battery is low. You can also check the battery level in the Ring app — open the device, tap the settings icon, and look for the battery percentage.

If you live in a cold climate, battery drain is faster in winter. You may need to charge more often during cold months. Extreme cold can also slow down charging, so if you are charging a device that has been outside in freezing weather, let it warm up to room temperature first.

Frequently Asked Questions

Can I use my phone charger to charge my Ring device?

Yes, if it has the right connector type. If your Ring device uses USB-C and your phone charger is USB-C, you can use it. The device will charge at whatever speed the charger provides. Ring does not officially support third-party chargers, but using a higher-wattage charger will not damage the device.

Why is my Ring device charging so slowly?

The most common reasons are a low-power charger, a damaged cable, or the device being too hot. Try a different charger or cable first. If the device feels warm, move it to a cooler location and try again. If it still charges slowly, the battery itself may be failing and you may need to contact Ring support.

Can I use my Ring device while it is charging?

Yes, but it will charge much more slowly because the battery is draining while it charges. If you need the device back in service, it is better to charge it without using it. If you must use it, expect the charging time to double or triple.

What happens if I leave my Ring device plugged in after it is fully charged?

Ring devices stop charging once the battery reaches 100 percent, so leaving it plugged in will not overcharge it or damage the battery. However, keeping a battery at 100 percent for long periods can slightly reduce its lifespan over years of use. If you are storing a device for months, charge it to about 50 percent instead.
