Understanding Your Eufy Video Doorbell Power Options

Before we dive into the charging process, it’s important to understand how your Eufy doorbell gets its power. Eufy offers two main types of video doorbells: battery-powered and hardwired. Each has its own charging and maintenance needs.

Battery-Powered Models

Most Eufy doorbells, like the Eufy Video Doorbell (Solo) and Eufy Video Doorbell S330, are designed to run on rechargeable lithium-ion batteries. These models are ideal for homes without existing doorbell wiring or for renters who can’t make permanent installations. The battery is removable, making it easy to take it inside for charging.

On average, a fully charged battery lasts between 2 to 6 months, depending on usage. Factors like frequent motion detection, live streaming, extreme temperatures, and Wi-Fi signal strength can drain the battery faster. For example, if you live on a busy street or have pets that trigger motion alerts often, you may need to charge your doorbell more frequently.

Hardwired Models

Some Eufy doorbells, such as the Eufy Video Doorbell Dual (Wired), are designed to be connected directly to your home’s existing doorbell wiring. These models draw power from your electrical system, so they don’t rely solely on a battery. However, many hardwired Eufy doorbells still include a backup battery to keep the device running during power outages.

Even if your doorbell is hardwired, it’s a good idea to check the battery periodically. Over time, the backup battery may degrade and need replacement. Plus, if your home experiences frequent power fluctuations, a healthy battery ensures your doorbell stays online when you need it most.

Hybrid Models: Best of Both Worlds

A few Eufy models, like the Eufy Video Doorbell Dual, offer hybrid power options—meaning they can be installed with wiring but also include a rechargeable battery. This gives you the reliability of wired power with the safety net of battery backup. In these cases, the battery charges automatically when wired power is available, but you may still need to manually charge it if the battery is old or damaged.

What You’ll Need to Charge Your Eufy Video Doorbell

Charging your Eufy doorbell is simple, but having the right tools makes the process smoother and safer. Here’s what you’ll need:

Official Eufy USB charging cable: This usually comes in the box. It’s a USB-A to Micro-USB or USB-C cable, depending on your model.
Compatible USB power adapter: Use the one that came with your doorbell or a trusted brand like Anker, Belkin, or Apple. Avoid cheap, no-name chargers.
A stable power source: Plug into a wall outlet, not a computer USB port, for faster charging.
Soft cloth or microfiber towel: For cleaning the battery and doorbell contacts.
Optional: Spare battery: If you have one, you can swap it in while charging the old one to avoid downtime.

⚠️ Important: Never use a fast charger (like a 30W or 65W USB-C PD charger) unless specified by Eufy. High-voltage chargers can overheat the battery and reduce its lifespan.

Step-by-Step: How to Charge a Battery-Powered Eufy Video Doorbell

Now that you’re prepared, let’s walk through the process of charging your Eufy doorbell battery. Follow these steps carefully to ensure a safe and effective charge.

Step 1: Check the Battery Level

Before removing the battery, check how much charge is left. Open the Eufy Security app on your smartphone and go to your doorbell device. Look for the battery icon—usually in the top-right corner of the live view screen. The app will show a percentage or a visual indicator (like a battery bar).

If the battery is below 20%, it’s time to charge. You’ll also receive a push notification from the app when the battery is low. Don’t wait until it’s completely dead—lithium-ion batteries last longer when you avoid full discharges.

Step 2: Remove the Doorbell from the Mount

To access the battery, you’ll need to detach the doorbell from its mounting bracket. Here’s how:

Locate the release button on the bottom or side of the doorbell (varies by model).
Press and hold the button while gently pulling the doorbell away from the wall.
Some models may require a small screwdriver to loosen a security screw—check your user manual if unsure.

💡 Pro Tip: Do this during the day when visibility is good. If your doorbell is high up, use a sturdy step ladder and have someone assist you if needed.

Step 3: Remove the Battery

Once the doorbell is off the wall, flip it over to access the battery compartment.

Look for a small latch or sliding cover on the back or bottom.
Slide or press the latch to open the compartment.
Gently lift the battery out by the handle or edge—don’t force it.

The battery is usually a flat, rectangular lithium-ion pack labeled with “Eufy” and a model number (e.g., B07XK5Z5Z5). Handle it carefully—avoid puncturing or bending it.

Step 4: Connect the Charging Cable

Now it’s time to charge the battery.

Take the official Eufy USB cable and plug the small end (Micro-USB or USB-C) into the port on the battery.
Plug the USB-A end into a wall adapter, then connect the adapter to a power outlet.
You should see a small LED light on the battery turn red or orange, indicating it’s charging.

🔋 Charging Time: Most Eufy batteries take 4 to 6 hours to fully charge. Avoid unplugging it early—partial charges can reduce long-term battery health.

Step 5: Monitor the Charging Progress

While the battery charges, you can check its status:

The LED light will typically turn green or blue when fully charged.
Some batteries have a small display showing the charge percentage.
If you’re using a smart plug or timer, set it to turn off after 6 hours to prevent overcharging (though modern batteries have built-in protection).

🚫 Don’t Leave It Plugged In Forever: While overcharging isn’t usually a risk due to built-in safeguards, it’s still best to unplug the battery once it’s full to save energy and reduce wear.

Step 6: Reinstall the Battery and Doorbell

Once charged, it’s time to put everything back.

Slide the battery back into the compartment until it clicks into place.
Close the latch securely.
Align the doorbell with the mounting bracket and press it firmly until it snaps in.
Test the doorbell by pressing the button or checking the live view in the app.

✅ Success! Your Eufy doorbell is now charged and ready to protect your home.

How to Charge a Hardwired Eufy Doorbell with Backup Battery

If your Eufy doorbell is hardwired, you might think you don’t need to worry about charging. But remember—many models include a backup battery that still needs maintenance.

Step 1: Check the Backup Battery Status

Open the Eufy Security app and go to your doorbell settings. Look for “Battery Health” or “Power Status.” If the backup battery is low or failing, you’ll see a warning.

Step 2: Access the Battery (If Removable)

Some hardwired models allow you to remove the backup battery for charging, similar to battery-only models. Follow the same steps as above: remove the doorbell, open the compartment, and charge the battery.

Step 3: Let It Charge Automatically (If Non-Removable)

On some models, the backup battery charges automatically when wired power is connected. In this case, ensure your doorbell is properly wired and receiving power. If the battery isn’t charging, check your home’s circuit breaker or consult an electrician.

Step 4: Replace the Battery If Needed

Backup batteries typically last 2–3 years. If your doorbell frequently loses power during outages or shows “Battery Error” in the app, it may be time for a replacement. Contact Eufy support or check their website for compatible batteries.

Tips to Extend Your Eufy Doorbell Battery Life

Charging your doorbell is one thing—keeping it charged longer is another. Here are practical tips to maximize battery life:

Adjust Motion Detection Settings

Frequent motion alerts drain the battery fast. In the Eufy app:

Reduce motion sensitivity.
Set activity zones to ignore areas like busy streets or trees.
Use “Person Only” detection to filter out animals or vehicles.

Limit Live View Usage

Streaming video uses a lot of power. Only use live view when necessary, and avoid leaving it open for long periods.

Enable Power-Saving Mode

Some Eufy models offer a “Power Saving” or “Eco Mode” that reduces video quality or frame rate to save battery. Turn this on during low-risk times (e.g., overnight).

Keep the Doorbell Clean

Dirt, snow, or ice on the lens or sensors can cause false alerts. Wipe the doorbell with a soft cloth weekly to maintain accuracy.

Install in a Shaded Area

Extreme heat can degrade battery performance. If possible, mount your doorbell in a spot that’s not in direct sunlight all day.
