Eufy S330 Camera Not Charging? (Easy Fixes You Can Try!)

If you face the “Eufy S330 camera not charging” issue, this means that the device will soon run out of juice and completely turn off, compromising your security.

The culprits for this problem often include poor sunlight exposure, outdated firmware, extreme temperatures, loose mount connections, or a dirty panel.

Don’t worry–whatever it is, this quick guide will walk you through the entire solution process!

How to Know When the Eufy S330 Camera is Charging?

The easiest way to know whether the camera is charging is by looking at the LED indicator:

If you can’t tell whether the camera is charging by looking at the indicator, open the eufy Security app and go to the sidebar → Settings → Power Management.

Eufy S330 Camera Not Charging – Most Effective Ways to Fix!

Note: Have you checked if the solar panel and USB-C cable are connected to the camera?

1. Clean the Solar Panel & Tilt the Camera

An obstructed solar panel might be the underlying reason why your eufy camera is not charging. 

Over time, dust, debris, leaves, snow, or even bird droppings pile up and often completely block sunlight from reaching the panel, reducing the exposure, which prevents the charging process.

A simple cleaning of the solar panel makes a huge difference!

Here’s how to clean the S330 solar panel:

1. First, acquire a clean and dry microfiber cloth.
2. Gently wipe and clean the solar panel surface. 
3. Ensure you don’t push or scratch the surface. 
4. Avoid using harsh chemicals, liquids, or water.
5. Finally, let the camera charge for ~30 minutes.

⚠️Important: If you’re solely relying on the solar panel to charge your eufy S330 camera, you need to ensure at least 2 hours of direct sunlight per day to keep the camera up and running 24/7.

2. Relocate the Panel for Better Exposure

If the S330 solar panel can’t receive direct and consistent sunlight during the day for a minimum of ~2 hours (preferably more), it won’t charge the camera sufficiently.

So, relocating the panel to a different place might be the perfect opportunity to catch even more sun rays and increase the charging efficiency of your eufy camera.

What is the Best Place for a Solar Panel?

The first step is to evaluate the current placement of the panel. Is it installed under a roof overhang, near trees, or somewhere that gets shaded?

If yes, then the spot isn’t ideal, and you’ll need to find a better place for better sun exposure during the day.

Here are some ideas to consider:

Tip: If you live in the Northern Hemisphere, face the panel to the south and vice versa!

Alternative Option!

Well, if you don’t want to relocate your current mounting spot, you can still improve charging by adjusting the angle of the solar panel.

The idea is to get direct sunlight for as long as possible. To achieve that, tilt the panel upward at a 30–45° angle so the entire solar panel captures more sunlight.

Also, occasionally test new angles where the panel gets direct sunlight during the day.

3. Charge Through the HomeBase USB Port

Perhaps, the integrated solar panel or cable connector might not be as effective as it should be, especially during the rainy and cloudy season.

So, there are two other options to consider:

3.1 Charge through HomeBase

One of the best ways to charge the eufy S330 camera would be through HomeBase’s 5V/2A USB-C port.

This is very easy, but of course, requires dismounting your camera and bringing it inside until the battery is full, and then mounting it again.

Here’s how to charge the S330 using the HomeBase USB-C port:

1. Grab the original USB-C charging cable that came with the camera.
2. Connect the eufy camera and HomeBase USB port using the cable.
3. Leave the camera plugged in until it reaches at least ~90% charge.

3.2 Charge through AV Adapter

Another way of charging the camera would be via a power adapter, 9V/2A, 5V/2A, or a 5V/1A, which plugs directly into an electrical outlet. 

Here’s how much you would need to wait, using different charging methods:

Reminder: Please refer to the steps at the start of the guide to check whether your eufy S330 camera is charging through the eufy Security application.

4. Test Panel USB-C Cable with a Multimeter

As mentioned in solution #3, the fault might be with the solar panel, commonly found within the wiring (USB-C cable) or cable connectors. 

To verify if that’s the case, ZontSound suggests testing the USB-C cable and camera power port connectors using a Multimeter.

Here’s how to test the S330 solar panel wiring:

1. Power OFF the camera through your eufy Security app.
2. Remove the solar panel USB-C cable from the camera.
3. Examine the USB-C connector for rust or frayed wiring.

Now test the USB-C cable using a multimeter via these steps:

If it’s 0 or fluctuating heavily, the S330 solar panel might be faulty.

If the voltage is 5V DC, which is a compatible voltage, but the eufy S330 camera isn’t charging, the USB-C wire may be faulty.

5. Charge the Camera with Another Cable

If you’ve tried different charging methods but your eufy S330 camera won’t charge, the problem could be with the USB-C charging cable.

This mainly happens due to overexposure to outdoor conditions, and to rule out this possibility, try charging your eufy via a replacement USB-C cable.

If the application is showing the lighting icon and the battery increases, it confirms your original USB-C cable is likely defective or there’s a fault with the solar panel.

6. Change the Environmental Temperature

The eufy cameras are sensitive to extreme temperatures.

If the temperature outside where the camera is mounted is above 50°C/ below -20°C, your camera is programmed to stop charging to preserve the battery.

So, you need to return the camera to its normal operating temperature. So, the idea here is to avoid the extremes, so a room’s temperature will do the job.

This means moving your camera inside for about ~20–30 minutes.

This will acclimate the battery, and while the camera is indoors, you can try charging it via a power adapter or HomeBase USB-C cable.

7. Lower your Camera’s Motion Sensitivity

• The motion sensitivity is the greatest battery drainer! 

Hence, if you wake up every morning to a dead eufy S330 battery, this generally means that the solar panel can’t catch up with the battery drainage.

Well, during the winter months, when the sun is hidden behind clouds, the reports of eufy battery-lasting problems increase significantly. 

Well, many people have managed to solve this problem by lowering the sensitivity, which will, of course, decrease the number of events and preserve the longevity of your eufy S330 battery.

Here’s how to lower eufy S330 motion sensitivity:

1. Open the eufy Security app on your phone.
2. Then, from the S330 card, hit the “…” button.
3. Next, head to Settings → Motion Detection.
4. Adjust the Sensitivity slider to a lower level.
5. Ideally, around 3 or 4 is usually recommended.
6. Save the settings and monitor the performance.

Tip: You can also set Activity Zones to limit detection to specific areas in the camera view, which will further decrease battery drainage.

8. Upgrade Your eufy Camera Firmware

Sometimes, even if rarely, when the Eufy S330 camera is not charging, the problem comes because of an outdated firmware.

Some old software builds can either affect the actual charging process or simply impact the eufy Security application to show the wrong battery charging percentage.

eufy often releases firmware updates to resolve such charging-related glitches, so updating the camera firmware fixes the issue.

Here’s how to update the eufy S330 camera firmware:

While the camera firmware is upgrading, you must confirm that the camera stays connected and powered on.

Also, your phone is connected to a strong Wi-Fi network. Otherwise, your firmware won’t install correctly and will cause even more issues.

If the issue persists after trying all the steps explained in this guide, we strongly advise you to contact eufy Customer Support for more help.
