Let’s dive in.

What Is the Eufy Card?

Before we get into charging, let’s quickly cover what the Eufy Card actually is. The Eufy Card is a compact, rechargeable smart card designed for contactless payments and access control. It’s part of the Eufy Security ecosystem, which includes smart home devices like cameras, doorbells, and locks.

The card is slim, credit-card-sized, and built with a rechargeable lithium-polymer (Li-Po) battery. It connects to your smartphone via Bluetooth and syncs with the Eufy Security app for setup, monitoring, and firmware updates. Because it’s used frequently for daily tasks—like unlocking doors or making payments—keeping it charged is essential.

Unlike traditional cards, the Eufy Card doesn’t rely on disposable batteries. Instead, it’s designed to be recharged hundreds of times, making it both eco-friendly and cost-effective over time.

What You’ll Need to Charge Your Eufy Card

Charging your Eufy Card doesn’t require fancy equipment. Here’s what you’ll need:

• A USB-C cable: The Eufy Card uses a USB-C port for charging. While it may come with a cable, any high-quality USB-C cable will work.
• A USB power adapter: You can use the one that came with your phone, a laptop USB port, or a wall charger. Aim for 5V/1A output for safe charging.
• A clean, dry surface: Avoid charging near water or in humid areas like bathrooms.
• The Eufy Security app (optional but recommended): Use it to check battery level and receive charging notifications.

Avoid using damaged cables or cheap, uncertified chargers. These can cause slow charging, overheating, or even damage the card’s internal components.

Step-by-Step: How to Charge Your Eufy Card

Now, let’s go through the actual charging process. Follow these steps carefully to ensure a safe and effective charge.

Step 1: Locate the Charging Port

The Eufy Card has a small USB-C charging port, usually located on the side or edge of the card. It’s a tiny rectangular slot—similar to what you’d find on modern smartphones or earbuds.

Gently inspect the card to find the port. It may be covered by a small rubber flap to protect against dust and moisture. If your model has a flap, gently lift it to expose the port.

Step 2: Connect the USB-C Cable

Take your USB-C cable and insert the smaller end into the charging port on the Eufy Card. Make sure it’s inserted the right way—USB-C is reversible, so it should fit no matter which side is up.

Push the cable in gently until it’s fully seated. You shouldn’t need to force it. If it doesn’t go in easily, double-check the orientation or inspect the port for debris.

Step 3: Plug Into a Power Source

Now, connect the other end of the USB-C cable to a power source. This could be:

• A wall charger plugged into an outlet
• A USB port on your laptop or desktop computer
• A powered USB hub

For fastest and safest charging, we recommend using a wall charger with a 5V/1A output. Avoid fast chargers (like those used for phones with high wattage), as they can generate excess heat and stress the battery.

Step 4: Monitor the LED Indicator

Once connected, the Eufy Card will show a small LED light near the charging port. This light tells you the current charging status:

• Red light: The card is charging.
• Green light: The card is fully charged.
• Blinking red light: There may be a charging issue (we’ll cover troubleshooting later).

The red light will stay on while charging and turn green once the battery reaches 100%. This usually takes about 1 to 2 hours, depending on the current battery level and power source.

Step 5: Wait for Full Charge

Leave the card connected until the LED turns green. Avoid unplugging it too early—partial charges are fine occasionally, but regular full charges help maintain battery health.

While charging, keep the card on a flat, stable surface. Don’t stack items on top of it or place it in a pocket or bag, as this can trap heat and reduce efficiency.

Step 6: Disconnect and Store Safely

Once the light turns green, unplug the cable from the card. Close the rubber flap (if applicable) to protect the port.

Store your Eufy Card in a cool, dry place. Avoid extreme temperatures—don’t leave it in a hot car or near a heater.

How Long Does It Take to Charge a Eufy Card?

Charging time depends on a few factors:

• Battery level: A nearly dead card will take longer than one that’s half-full.
• Power source: Wall chargers are faster than laptop USB ports.
• Cable quality: Damaged or low-quality cables can slow charging.

On average, a full charge takes **1 to 2 hours**. If it’s taking significantly longer, there may be an issue with the cable, charger, or card itself.

How Often Should You Charge Your Eufy Card?

The Eufy Card is designed for daily use, and its battery life typically lasts **5 to 7 days** on a full charge, depending on usage.

If you use the card frequently—for example, unlocking your front door multiple times a day or making contactless payments—you may need to charge it every 3 to 4 days. Light users might go a full week without recharging.

To keep track, check the battery level in the Eufy Security app. The app shows a percentage and sends low-battery alerts when it drops below 20%.

We recommend charging your Eufy Card **once a week** as a routine, even if it’s not fully drained. This helps maintain battery health and ensures it’s always ready when you need it.

Best Practices for Charging Your Eufy Card

To get the most out of your Eufy Card’s battery, follow these best practices:
