We’ll also cover tips to extend battery life, troubleshoot common issues, and answer frequently asked questions. By the end, you’ll be confident in maintaining your Eufy Doorbell 2K so it’s always ready to protect your home.

Understanding Your Eufy Doorbell 2K Model

Before you begin charging, it’s important to know which version of the Eufy Doorbell 2K you have. Eufy offers two main models:

Battery-Powered Model: Runs on a built-in rechargeable battery. This version is ideal for homes without existing doorbell wiring.
Hardwired Model: Connects to your home’s existing doorbell wiring and includes a backup battery. It charges continuously via wiring but can run on battery during power outages.

While both models have rechargeable batteries, the charging process is slightly different. The battery-powered version requires manual removal and charging, while the hardwired model can often be charged without removal—though removing it for charging is still recommended for full power restoration.

Knowing your model helps you follow the right steps and avoid confusion. You can check your model in the Eufy Security app under “Device Settings” or look at the packaging and device label.

What You’ll Need to Charge Your Eufy Doorbell 2K

Gather these items before starting the charging process:

The Eufy Doorbell 2K device
The included USB-C charging cable
A 5V/2A USB power adapter (the one that came with the doorbell or a compatible one)
A small Phillips-head screwdriver (for removal, if needed)
A clean, dry cloth (to wipe the device)
A safe, flat surface to charge the doorbell (like a table or counter)

Avoid using fast chargers or high-voltage adapters (like those for laptops), as they can damage the battery. Stick to the recommended 5V/2A output for safe and efficient charging.

Step-by-Step: How to Charge Eufy Doorbell 2K (Battery-Powered Model)

If you have the battery-powered Eufy Doorbell 2K, follow these steps to charge it safely and effectively.

Step 1: Check the Battery Level in the Eufy App

Before removing the doorbell, check the current battery level using the Eufy Security app:

Open the Eufy Security app on your smartphone.
Tap on your doorbell device.
Look for the battery icon—usually in the top-right corner.
If the battery is below 20%, it’s time to charge.

Charging when the battery is low helps maintain battery health. Avoid letting it drain completely, as this can reduce long-term battery lifespan.

Step 2: Turn Off Motion Detection (Optional but Recommended)

To prevent false alerts while the doorbell is off, temporarily disable motion detection:

In the Eufy app, go to your doorbell settings.
Tap “Motion Detection” and toggle it off.
You can also disable notifications to avoid interruptions.

This step isn’t mandatory, but it prevents the app from sending alerts when the doorbell is removed or inactive.

Step 3: Remove the Eufy Doorbell 2K from the Mount

Now it’s time to safely detach the doorbell:

Locate the small security screw at the bottom of the doorbell faceplate.
Use the Phillips-head screwdriver to loosen and remove the screw.
Gently pull the doorbell away from the mounting plate. It should slide out smoothly.
Be careful not to force it—there’s a small latch mechanism that releases when the screw is removed.

If the doorbell feels stuck, double-check that the screw is fully removed. Never pry it with a knife or metal tool, as this can damage the casing or internal components.

Step 4: Disconnect the Battery (If Applicable)

Some Eufy Doorbell 2K models have a removable battery, while others have a built-in one. For models with a removable battery:

Flip the doorbell over and locate the battery compartment.
Press the release tab and slide the battery out.
Handle the battery carefully—avoid bending or puncturing it.

For built-in batteries, you can charge the doorbell directly without removing the battery.

Step 5: Connect the USB-C Cable

Now, plug in the charger:

Take the included USB-C cable and connect it to the charging port on the doorbell (usually on the back or side).
Plug the other end into the 5V/2A power adapter.
Connect the adapter to a wall outlet.

A small LED light on the doorbell will turn red when charging begins. This indicates the device is receiving power.

Step 6: Charge Until Full

Let the doorbell charge completely:

A full charge typically takes 4 to 6 hours.
The LED light will turn green when charging is complete.
Do not unplug it immediately—wait until the light is solid green.

Avoid interrupting the charging process. Partial charges are fine occasionally, but full charges help calibrate the battery meter in the app.

Step 7: Reattach the Battery (If Removed)

If you removed the battery:

Slide it back into the compartment until it clicks into place.
Ensure it’s seated properly to avoid connection issues.

Step 8: Reinstall the Doorbell

Now, put the doorbell back on the mount:

Align the doorbell with the mounting plate.
Gently push it into place until it clicks.
Reinsert and tighten the security screw at the bottom.
Make sure it’s secure but don’t overtighten—this can strip the screw or crack the plastic.

Step 9: Re-enable Motion Detection

Once reinstalled:

Open the Eufy app.
Go back to your doorbell settings.
Turn motion detection and notifications back on.

Your doorbell should now be fully charged and operational.

Charging the Hardwired Eufy Doorbell 2K

If you have the hardwired version, the process is similar, but with a few key differences.

Option 1: Charge Without Removing (If Wired)

Since the hardwired model draws power from your home’s wiring, it charges continuously. However, if the backup battery is low (e.g., after a power outage), you may still need to charge it manually.

Check the battery level in the Eufy app.
If below 20%, consider removing it for a full charge.
Even when wired, the battery may not charge fully if the wiring is weak or intermittent.

Option 2: Remove and Charge (Recommended for Full Charge)

For a complete charge, follow the same steps as the battery-powered model:

Turn off power to the doorbell at the circuit breaker (safety first!).
Remove the doorbell using the security screw.
Charge via USB-C as described earlier.
Reinstall and restore power.

Always turn off the power before removing a hardwired doorbell to avoid electrical shock.

Tips to Extend Battery Life

Charging your Eufy Doorbell 2K is only part of the equation. To maximize battery life between charges, follow these practical tips:

Adjust Motion Detection Sensitivity

High sensitivity can trigger frequent recordings, draining the battery faster.

In the Eufy app, go to “Motion Detection” settings.
Lower the sensitivity to “Medium” or “Low.”
Set activity zones to ignore areas like busy streets or trees.

This reduces unnecessary recordings and saves power.

Reduce Video Quality (Temporarily)

2K video uses more battery than lower resolutions.

Go to “Video Settings” in the app.
Switch to “1080p” when battery is low.
Switch back to 2K when charged.

This is a temporary fix—use 2K for best security when possible.

Limit Live View Usage

Each time you open a live view in the app, the doorbell uses power.

Only use live view when necessary.
Avoid keeping the stream open for long periods.

Enable Smart Alerts

Use AI-powered person detection to reduce false alerts.

In the app, enable “Human Detection” under motion settings.
This prevents recordings from pets, leaves, or shadows.

Fewer recordings mean longer battery life.

Keep the Doorbell Clean

Dirt, dust, and snow can block sensors and cameras, causing the device to work harder.

Wipe the lens and sensors with a soft, dry cloth weekly.
Use a mild cleaner if needed—never spray directly on the device.

Avoid Extreme Temperatures

Cold weather reduces battery efficiency.

If you live in a cold climate, consider a weatherproof cover.
Charge the doorbell indoors—never in freezing temperatures.
Avoid placing it in direct sunlight in hot climates.

Troubleshooting Common Charging Issues

Even with proper care, you might encounter charging problems. Here’s how to fix them.

The Doorbell Won’t Charge

Possible causes and solutions:

Faulty cable or adapter: Try a different USB-C cable and 5V/2A adapter.
Loose connection: Ensure the cable is fully inserted into the doorbell.
Dirty charging port: Gently clean the port with a dry toothbrush or compressed air.
Dead battery: If the battery is completely drained, it may take 10–15 minutes of charging before the LED lights up.

LED Light Doesn’t Turn On

If the charging light doesn’t appear:

Check if the outlet is working—try another device.
Test the cable with another USB-C device.
Ensure the doorbell is powered off before charging (some models require this).

Battery Drains Too Fast

If the battery depletes quickly after charging:

Check for firmware updates in the Eufy app.
Reduce motion detection frequency.
Ensure the doorbell isn’t in a high-traffic area triggering constant alerts.
Consider replacing the battery if it’s over 2 years old.
