Before we get into how to check if your Eufy doorbell is charging, it’s important to understand the two main types of Eufy doorbells and how they get power.

Eufy offers both battery-powered and wired doorbell models. Each has its own charging method and indicators, so knowing which one you have will help you monitor its power accurately.

Battery-Powered Eufy Doorbells

Models like the Eufy Video Doorbell 2K (Battery) and Eufy Video Doorbell 2K (Solo) run on rechargeable lithium-ion batteries. These are ideal if you don’t have existing doorbell wiring or prefer a wireless setup. The battery typically lasts 2 to 6 months, depending on usage, motion detection settings, and climate.

When the battery runs low, you’ll need to remove the doorbell from its mount and charge it using a USB-C cable. Most Eufy battery doorbells come with a charging cable and recommend using a 5V/2A adapter for optimal charging speed.

Wired Eufy Doorbells

Wired models, such as the Eufy Doorbell Dual or Eufy Video Doorbell 2K (Wired), connect directly to your home’s existing doorbell wiring. These doorbills draw power from your home’s electrical system, so they don’t rely on a removable battery. Instead, they use that power to run continuously and even charge an internal backup battery.

For wired models to charge and function properly, your doorbell transformer must supply between 16 and 24 volts AC. If the voltage is too low, the doorbell may not charge or operate correctly.

Hybrid Models: Best of Both Worlds

Some Eufy doorbells, like the Eufy Video Doorbell 2K (Wired + Battery), combine both systems. They connect to wiring for constant power but also have a built-in battery as a backup during power outages. These models charge the internal battery when wired power is available.

No matter which type you have, the goal is the same: ensure your doorbell has enough power to record, send alerts, and stay online. Now, let’s look at the most reliable ways to check if your Eufy doorbell is charging.

Method 1: Check the LED Indicator Light

One of the easiest and most immediate ways to know if your Eufy doorbell is charging is by looking at the LED light on the device. Eufy doorbells use colored lights to communicate status, including charging progress.

What the LED Colors Mean

The LED indicator is usually located near the bottom or center of the doorbell face. Here’s what the different colors typically mean:

Solid White: The doorbell is powered on and functioning normally. For wired models, this means it’s receiving power from the wiring.
Blinking White: The doorbell is in setup mode or connecting to Wi-Fi. Not directly related to charging, but indicates activity.
Solid Red: The battery is critically low (usually below 10%). You should charge it soon.
Blinking Red: The battery is charging. This is a key sign that your Eufy doorbell is charging, especially for battery-powered models.
Solid Green: The battery is fully charged. If you see this after plugging in the doorbell, charging is complete.
Blinking Green: The doorbell is charging and nearing full capacity. Some models use this to show progress.

For example, if you’ve just plugged in your battery-powered Eufy doorbell via USB and see a blinking red light, that’s a clear signal it’s charging. Once it turns solid green, you’re good to go.

Where to Find the LED Light

The exact location of the LED varies by model, but it’s usually visible on the front face of the doorbell. On the Eufy Video Doorbell 2K, it’s a small circular light near the bottom. On the Eufy Doorbell Dual, it’s integrated into the center display area.

If you’re having trouble seeing the light—maybe it’s too dim or hidden by shadows—try checking it in a well-lit area or at night when the contrast is better.

Tips for Reading the LED Correctly

Wait a few minutes: After plugging in the doorbell, give it 2–3 minutes before checking the light. Some models take a moment to detect the power source.
Don’t block the sensor: Make sure your hand or mount isn’t covering the LED when you look at it.
Check during daylight and night: Some LEDs are brighter in the dark, so test visibility in different lighting.

If the LED doesn’t light up at all when you plug in the doorbell, that could indicate a problem with the cable, adapter, or the doorbell itself—more on troubleshooting later.

Method 2: Use the Eufy Security App

The Eufy Security app is your digital command center for all Eufy devices, including your doorbell. It provides real-time information about battery level, charging status, and device health.

How to Check Charging Status in the App

Follow these steps to see if your Eufy doorbell is charging using the app:

Open the Eufy Security app on your smartphone or tablet.
Tap on your doorbell from the home screen to open its live view.
Look at the battery icon in the top-right corner of the screen. It shows the current battery percentage.
Check for a charging symbol: If the doorbell is plugged in and charging, you may see a small lightning bolt or “Charging” label next to the battery icon.
Review the device status: Scroll down to the “Device Status” section. It will say “Charging” if power is being supplied.

For example, if your battery shows 45% and the status says “Charging,” you know the doorbell is actively gaining power. If it says “Not Charging” despite being plugged in, there may be an issue.

Enable Low-Battery Notifications

The app can send you push notifications when your doorbell’s battery drops below a certain level—usually 20%. To make sure you’re alerted:

Go to Device Settings > Notifications.
Turn on Low Battery Alerts.
Set the threshold to 20% or lower.

This way, you’ll get a notification before the battery dies, giving you time to recharge.

View Charging History (Advanced Users)

Some Eufy models allow you to view battery usage trends in the app. While not all versions show detailed charging logs, you can infer charging patterns by checking the battery percentage over time.

For instance, if you charge your doorbell every Monday and the battery jumps from 30% to 90% in two hours, you know it’s charging efficiently. If it only goes up 10% in the same time, there might be a problem.

App Tips for Accurate Readings

Keep the app updated: Eufy regularly releases updates that improve battery monitoring.
Ensure stable Wi-Fi: A weak connection can delay status updates in the app.
Log in regularly: The app syncs data when opened, so check it daily for the most accurate info.

The Eufy app is one of the most reliable tools for monitoring your doorbell’s power. Combine it with the LED indicator for double confirmation.

Method 3: Monitor Charging with a USB Cable (Battery Models)

If you have a battery-powered Eufy doorbell, you’ll need to remove it from the wall and charge it manually using a USB cable. Here’s how to do it safely and effectively.

Step-by-Step Charging Process

Remove the doorbell from the mount: Use the included removal tool or a small flathead screwdriver to gently pry it off.
Locate the USB-C port: It’s usually on the back or bottom of the device.
Connect the USB-C cable: Plug one end into the doorbell and the other into a 5V/2A power adapter.
Plug the adapter into a wall outlet: Avoid using computer USB ports, as they may not provide enough power.
Wait for the LED to respond: Within a few minutes, the LED should blink red, indicating charging has started.

How Long Does It Take to Charge?

Most Eufy battery doorbells take 3 to 6 hours to charge from 0% to 100%. The exact time depends on the battery capacity and the power source.

For example:

Eufy Video Doorbell 2K (Battery): ~4 hours with a 2A adapter.
Eufy Video Doorbell 2K (Solo): ~5 hours due to a larger battery.

Avoid using fast chargers (like 9V or 12V adapters), as they can damage the battery. Stick to 5V/2A for safety and longevity.

Signs Charging Is Working

While charging, you should see:

A blinking red LED light.
The Eufy app showing “Charging” status (if the doorbell is still connected to Wi-Fi).
The battery percentage increasing over time.

If the LED doesn’t light up or the battery percentage doesn’t change after an hour, there may be an issue with the cable, adapter, or battery.

Best Practices for Battery Care

Charge regularly: Don’t wait until the battery is completely dead. Recharge when it hits 20–30%.
Use the original cable: Third-party cables may not deliver consistent power.
Store in a cool, dry place: Avoid leaving the doorbell in direct sunlight or freezing temperatures while charging.

Proper charging habits extend battery life and ensure your doorbell is always ready.

Method 4: Check Wired Power Supply (Wired Models)

If you have a wired Eufy doorbell, it doesn’t use a removable battery. Instead, it draws power from your home’s doorbell wiring. But how do you know if it’s charging the internal backup battery?

Verify the Transformer Voltage

The most common reason wired doorbells fail to charge is insufficient voltage. Your doorbell transformer should output between 16 and 24 volts AC.

To check:

Turn off power at the breaker: Safety first!
Remove the doorbell from the wall.
Use a multimeter: Set it to AC voltage and touch the probes to the doorbell wires.
Read the voltage: If it’s below 16V, the doorbell may not charge properly.

If the voltage is too low, you may need to upgrade your transformer. Many older homes have 8V or 12V transformers, which aren’t enough for modern smart doorbells.

Look for Power Indicators

Even though wired doorbells don’t have removable batteries, they often have internal backup batteries that charge when wired power is available.

Signs that charging is working:

The LED shows a solid white or green light.
The Eufy app shows “Powered” or “Charging” status.
The doorbell functions normally during a power outage (thanks to the backup battery).

If your wired doorbell dies during a blackout, the backup battery may not be charging—check the wiring and transformer.

Ensure Proper Wiring Connections

Loose or corroded wires can interrupt power flow. Make sure:

The wires are securely connected to the doorbell terminals.
There’s no fraying or damage to the wires.
The mounting plate is tight and makes good contact.

If you’re unsure about electrical work, consult a licensed electrician.

Troubleshooting: What If Your Eufy Doorbell Isn’t Charging?

Even with the best care, charging issues can happen. Here’s how to diagnose and fix common problems.

LED Doesn’t Light Up When Plugged In

Possible causes:

Faulty USB cable or adapter: Try a different cable or power source.
Dirty charging port: Use a dry toothbrush to clean the USB-C port.
Dead battery: If the battery is completely drained, it may take 10–15 minutes of charging before the LED responds.

Battery Percentage Doesn’t Increase

Try this:

Restart the doorbell: Remove it, wait 10 seconds, then reconnect.
Reset the device: Hold the setup button for 10 seconds to reset.
Update the firmware: Open the Eufy app and check for updates under Device Settings.
