Whether your doorbell is battery-powered or hardwired with a backup battery, this guide applies to most Eufy models. Let’s get started!

Why Charging Your Eufy Doorbell Matters

Before diving into the steps, it’s important to understand why charging your Eufy doorbell is so crucial. Unlike traditional doorbells that run on household wiring, many Eufy models rely on rechargeable lithium-ion batteries. These batteries power the camera, motion sensor, Wi-Fi connectivity, and two-way audio—all features that make your doorbell “smart.”

If the battery dies, your doorbell essentially becomes a decorative piece. You won’t receive motion alerts, live video feeds, or notifications when someone presses the button. Worse, you might miss important events like a delivery, a visitor, or even a potential security issue.

Even if your Eufy doorbell is hardwired, it still uses a rechargeable battery as a backup. This ensures the device keeps working during power outages. So, whether you have a battery-only model or a hybrid setup, regular charging is essential.

On average, a fully charged Eufy doorbell lasts between 1 to 3 months, depending on usage. High-traffic areas, frequent motion detection, and extreme weather can drain the battery faster. That’s why knowing how to charge a Eufy doorbell isn’t just helpful—it’s necessary for reliable home security.

What You’ll Need to Charge Your Eufy Doorbell

Before you begin, gather the following items to ensure a smooth charging process:

• The Eufy doorbell unit (obviously!)
• The original USB charging cable (usually USB-C or micro-USB, depending on your model)
• A 5V/2A USB wall adapter (the one that came with your doorbell or a compatible one)
• A small Phillips-head screwdriver (for removing the security screw)
• A clean, dry cloth (to wipe the doorbell and charging port)
• A power source (wall outlet, power bank, or computer USB port)

Using the original cable and charger is highly recommended. Third-party cables or low-quality adapters can damage the battery or cause slow charging. If you’ve misplaced the original cable, check Eufy’s official website for replacement parts.

Also, make sure your charging environment is safe. Avoid charging in direct sunlight, near heaters, or in humid areas like bathrooms. Lithium-ion batteries perform best in cool, dry conditions.

Step 1: Turn Off the Power (For Hardwired Models)

If your Eufy doorbell is hardwired to your home’s electrical system, you must turn off the power before removing it. This prevents electrical shock and protects the device from damage.

Locate Your Doorbell Transformer

Most hardwired doorbells connect to a transformer, usually located in your basement, garage, or electrical panel. The transformer steps down your home’s 120V power to a safer 16–24V for the doorbell.

To turn off the power:

• Go to your home’s main electrical panel (breaker box).
• Look for the breaker labeled “doorbell,” “chime,” or something similar. If it’s not labeled, you may need to test breakers by turning them off one at a time and checking if your existing doorbell stops working.
• Switch the breaker to the “OFF” position.

Once the power is off, test the doorbell by pressing the button. If nothing happens, you’ve successfully cut the power.

Optional: Use a Non-Contact Voltage Tester

For extra safety, use a non-contact voltage tester near the doorbell wires. If the tester doesn’t beep or light up, the power is off. This is especially useful if you’re unsure about the correct breaker.

⚠️ Never skip this step if your doorbell is hardwired. Working with live wires can be dangerous and may void your warranty.

Step 2: Remove the Eufy Doorbell from the Mount

Now that the power is off (or if you have a battery-only model), it’s time to remove the doorbell from its mounting bracket.

Locate the Security Screw

Most Eufy doorbells are secured with a small security screw at the bottom of the device. This prevents theft and accidental removal.

Use your Phillips-head screwdriver to loosen and remove this screw. Keep it in a safe place—you’ll need it to reinstall the doorbell later.

Gently Slide the Doorbell Off

Once the screw is removed, gently pull the bottom of the doorbell away from the wall. It should slide down and out of the mounting bracket.

Be careful not to force it. If it feels stuck, double-check that the screw is fully removed and that no wires are tugging on the device.

Disconnect Wires (If Hardwired)

If your doorbell is hardwired, you’ll see two wires connected to the back of the device. These are usually labeled “Front” and “Trans” or “Front” and “Rear.”

Carefully disconnect the wires by pulling them straight out. Don’t yank or twist them. If they’re tight, use a small flathead screwdriver to gently pry them loose.

Label the wires with tape if needed, so you remember which goes where during reinstallation.

Step 3: Clean the Charging Port

Before plugging in the charger, take a moment to clean the charging port on your Eufy doorbell. Dust, dirt, or moisture can interfere with charging and cause poor connections.

Use a clean, dry cloth to wipe the port. For stubborn debris, gently use a soft-bristled toothbrush or a can of compressed air. Avoid using water or cleaning solutions—moisture can damage the electronics.

A clean port ensures a solid connection and faster, more reliable charging.

Step 4: Connect the Charging Cable

Now it’s time to plug in your Eufy doorbell.

Use the Correct Cable

Most newer Eufy doorbells use a USB-C cable, while older models may use micro-USB. Check your model number (usually on the back or in the Eufy app) to confirm.

Insert the cable into the charging port on the bottom or side of the doorbell. Make sure it’s fully seated—don’t force it, but ensure it clicks in securely.

Connect to a Power Source

Plug the other end of the cable into a 5V/2A USB wall adapter. Avoid using fast chargers (like those for phones) or laptop USB ports, as they may not provide consistent power.

Then, plug the adapter into a wall outlet. For best results, use a dedicated outlet—don’t share it with high-power devices like microwaves or space heaters.

💡 Pro Tip: If you’re charging overnight, use a power strip with a timer to automatically cut power after 6 hours. This prevents overcharging and extends battery life.

Step 5: Monitor the Charging Process

Once connected, your Eufy doorbell will begin charging. Most models have an LED indicator that shows the charging status.

Understanding the LED Indicator

Here’s what the lights mean:

• Red light: Battery is low and charging.
• Blinking red: Charging in progress.
• Solid green: Battery is fully charged.
• No light: Not charging—check connections.

Charging typically takes 4 to 6 hours, depending on the battery level and model. Avoid unplugging the doorbell before it reaches a full charge.

Check the Eufy App

You can also monitor charging progress in the Eufy Security app. Open the app, select your doorbell, and check the battery percentage. The app will update in real time as the battery charges.

This is especially helpful if your doorbell doesn’t have a visible LED or if you’re charging it out of sight.

Step 6: Reinstall the Doorbell

Once the battery is fully charged (solid green light), it’s time to put your doorbell back in place.

Reconnect Wires (If Hardwired)

If your doorbell is hardwired, reconnect the two wires to the back of the device. Match them to the correct terminals (Front and Trans/Rear). Push them in firmly until they click.

Slide the Doorbell Back Onto the Mount

Align the top of the doorbell with the mounting bracket and slide it down until it clicks into place. Make sure it’s secure and level.

Reattach the Security Screw

Use your screwdriver to reinsert the security screw at the bottom. Tighten it just enough to hold the doorbell in place—don’t overtighten, as this can crack the plastic.

Turn the Power Back On (For Hardwired Models)

Go back to your electrical panel and switch the breaker to the “ON” position. Wait a few seconds for the doorbell to power up.

Step 7: Test Your Doorbell

After reinstalling, it’s important to test your Eufy doorbell to ensure everything is working correctly.

Check the LED and App Status

Look for the LED indicator on the doorbell. It should show a solid white or green light, indicating it’s connected and functioning.

Open the Eufy Security app and verify that the doorbell is online. Check the battery level—it should show 100% or close to it.

Test Motion Detection and Video

Walk in front of the doorbell to trigger motion detection. You should receive a notification on your phone and see a live video feed in the app.

Press the doorbell button to test the chime and two-way audio. Speak into your phone and listen for clear sound from the doorbell.

Verify Wi-Fi Connection

Make sure the doorbell is connected to your Wi-Fi network. A weak signal can cause lag or disconnections. If needed, move your router closer or use a Wi-Fi extender.

Tips for Maintaining Battery Life

Charging your Eufy doorbell is only part of the equation. To get the most out of your device, follow these best practices for battery care:

Charge Regularly

Even if your doorbell is hardwired, charge the battery every 2–3 months. For battery-only models, charge every 1–2 months or when the app alerts you.

Avoid Extreme Temperatures

Heat and cold can damage lithium-ion batteries. If you live in a hot climate, consider installing the doorbell in a shaded area. In winter, avoid charging in freezing conditions.

Reduce Motion Sensitivity

High motion sensitivity drains the battery faster. In the Eufy app, adjust the sensitivity to “Low” or “Medium” if you’re getting too many false alerts.

Use Scheduled Modes

Set your doorbell to “Home” or “Away” mode in the app. This reduces recording frequency when you’re home, saving battery.

Keep the Lens Clean

A dirty lens can cause the camera to work harder, using more power. Wipe the lens monthly with a microfiber cloth.
