Understanding Your Eufy Device and Battery Type

Before you begin charging, it’s important to understand what kind of Eufy device you have and the type of battery it uses. Eufy offers a wide range of products, including indoor and outdoor security cameras, video doorbells, robot vacuums, and smart locks—each with different battery configurations.

Most Eufy security cameras, such as the Eufy SoloCam S40 or EufyCam 2C, use built-in rechargeable lithium-ion batteries. These are non-removable and charge via a USB cable. On the other hand, some models like the Eufy RoboVac series use removable lithium-ion battery packs that can be charged separately.

Identifying Your Eufy Model

To ensure you’re following the correct charging procedure, start by identifying your device model. You can usually find this information:

• On the device itself (check the back or bottom label)
• In the user manual that came with the product
• Within the Eufy Security app under “Device Settings”

For example, if you have a Eufy SoloCam E40, it uses a built-in 6000mAh battery that charges via a USB-C cable. In contrast, the Eufy RoboVac 11S uses a removable 2600mAh battery that can be charged outside the vacuum.

Types of Eufy Batteries

Eufy batteries generally fall into two categories:

• Built-in (non-removable): Found in most Eufy security cameras. These batteries are sealed inside the device and charge through a USB port.
• Removable (replaceable): Common in robot vacuums and some older camera models. These batteries can be taken out and charged independently.

Knowing which type your device uses will help you choose the right charging method and avoid confusion.

How to Charge Eufy Battery: Step-by-Step Instructions

Now that you understand your device, let’s walk through the actual process of charging your Eufy battery. The steps vary slightly depending on the product, so we’ll cover the most common scenarios.

Charging a Eufy Security Camera (Built-in Battery)

Most Eufy security cameras, like the EufyCam 2 or SoloCam S220, have built-in batteries that charge via USB. Here’s how to do it safely and effectively:

Step 1: Locate the Charging Port

Turn your camera over and look for the charging port. On most models, it’s a micro-USB or USB-C port located on the bottom or side of the device. Some outdoor cameras may have a weatherproof cover that needs to be lifted before accessing the port.

Step 2: Use the Original Charging Cable and Adapter

Always use the USB cable and power adapter that came with your Eufy camera. These are designed to deliver the correct voltage and current. Using third-party chargers—especially fast chargers or low-quality cables—can damage the battery or cause overheating.

If you’ve lost the original cable, purchase a replacement from Eufy’s official website or an authorized retailer. Avoid cheap, uncertified alternatives.

Step 3: Connect the Cable and Plug Into Power

Insert the USB cable into the camera’s charging port and connect the other end to the power adapter. Plug the adapter into a wall outlet. Avoid using USB ports on computers, TVs, or power strips, as they may not provide enough power for a full charge.

Step 4: Monitor the Charging Status

Most Eufy cameras have an LED indicator that shows charging progress:

• Red light: Battery is charging
• Green or blue light: Battery is fully charged
• No light: Check connections or try a different outlet

Charging time varies by model. For example, a EufyCam 2C typically takes 4–6 hours to charge from 0% to 100%. You can also check the battery level in the Eufy Security app.

Step 5: Disconnect When Fully Charged

Once the light turns green or the app shows 100%, unplug the cable. Overcharging won’t damage modern lithium-ion batteries due to built-in protection circuits, but it’s still best practice to disconnect to avoid unnecessary heat buildup.

Charging a Eufy Robot Vacuum (Removable Battery)

If you own a Eufy RoboVac, such as the 11S, 30C, or G30, the battery is usually removable and can be charged separately. Here’s how:

Step 1: Remove the Battery Pack

Turn off the RoboVac and flip it over. Locate the battery compartment—usually secured with a latch or screws. Press the release button or unscrew the cover to remove the battery pack.

Step 2: Use the Dedicated Charger (If Available)

Some Eufy RoboVac models come with a standalone battery charger. If yours does, plug the charger into a wall outlet and insert the battery. The charger’s LED will indicate charging status (red = charging, green = full).

If your model doesn’t include a separate charger, you can recharge the battery while it’s still inside the vacuum by docking the RoboVac on its charging station.

Step 3: Reinsert the Battery

Once charged, carefully place the battery back into the RoboVac and secure the compartment. Make sure it’s properly seated to avoid connection issues.

Charging via the Eufy App

The Eufy Security app is a powerful tool for monitoring and managing your devices—including battery status.

How to Check Battery Level in the App

1. Open the Eufy Security app on your smartphone.
2. Tap on the device you want to check (e.g., your camera or vacuum).
3. Look for the battery icon—usually displayed as a percentage or bar graph.
4. The app will also notify you when the battery is low (typically below 20%).

You can enable push notifications in the app settings to receive alerts when your device needs charging.

Best Practices for Charging Eufy Batteries

Charging your Eufy battery correctly is only part of the story. To maximize battery lifespan and performance, follow these best practices:

Use the Right Charger and Cable

As mentioned earlier, always use the original or Eufy-certified charger and cable. These are designed to match your device’s power requirements. Using incompatible chargers can lead to:

• Slow charging
• Overheating
• Battery degradation
• Potential safety hazards

For example, a 5V/2A adapter is ideal for most Eufy cameras. Avoid using fast chargers (like those for smartphones) unless specified by Eufy.

Avoid Extreme Temperatures

Lithium-ion batteries perform best at room temperature (around 20–25°C or 68–77°F). Charging in very hot or cold environments can damage the battery and reduce its lifespan.

Avoid charging your Eufy device:

• In direct sunlight (e.g., on a windowsill)
• Near heaters or radiators
• In a car during summer or winter
• Outdoors in freezing conditions

If your camera was exposed to extreme cold, let it warm up to room temperature before charging.

Don’t Let the Battery Drain Completely

While modern batteries don’t suffer from the “memory effect” like older nickel-based batteries, deep discharges can still stress the cells. Try to recharge your Eufy device when the battery drops to 20–30%, rather than waiting until it’s completely dead.

This habit helps maintain battery health and ensures your device is always ready when you need it.

Charge Regularly, Even If Not in Use

If you’re not using your Eufy camera or vacuum for an extended period (e.g., during travel), don’t leave the battery fully charged or completely drained. Instead:

• Charge the battery to around 50%
• Store the device in a cool, dry place
• Recharge to 50% every 3–6 months

This prevents the battery from entering a deep discharge state, which can make it difficult to recharge later.

Keep Charging Ports Clean

Dust, dirt, and moisture can accumulate in the charging port, leading to poor connections and slow charging. To clean:

• Use a dry, soft-bristled brush (like a clean toothbrush)
• Blow out debris with compressed air
• Avoid using water or cleaning solutions

For outdoor cameras, check the port cover regularly to ensure it’s sealed properly and free of dirt.

Troubleshooting Common Charging Issues

Even with proper care, you might encounter charging problems. Here’s how to diagnose and fix the most common issues.

Battery Won’t Charge

If your Eufy device isn’t charging, try these steps:

• Check the cable and adapter: Test with another cable or plug into a different outlet.
