eufy Baby Monitor Won't Turn On — How to Fix It

What Does This Error Mean?

For the camera unit: check the USB power adapter is firmly seated in both the camera and the wall outlet. For the parent unit (handheld monitor): ensure it is charged — hold the power button for 3 seconds. Unplug the camera for 30 seconds and reconnect to clear a firmware hang.

USB power adapter not fully inserted or faulty
Parent unit battery depleted needing charge
Firmware hang leaving the camera in an unresponsive state
Power outlet or USB port not supplying voltage
Physical damage to the camera's power port

How to Fix It

Check the power adapter connection

Firmly push the USB cable into both the camera's port and the adapter. Try a different wall outlet. eufy cameras use a 5V USB power supply — also try a different USB-A adapter.
Try a different USB cable and adapter

Use a different USB cable (standard USB-A to micro-USB or USB-C depending on your eufy model). A faulty cable is the most common cause of a camera that appears completely dead.
Charge the parent unit (handheld monitor)

If your eufy monitor has a standalone parent unit, connect it to its charger for 2 hours before pressing power. Hold the power button for 3 seconds to turn it on — a brief press may not register.
Perform a hard reset

Hold the camera's reset button (small pinhole, usually on the back or bottom) for 10 seconds using a pin or paperclip. The camera will restart and attempt to reconnect.
Test the power outlet

Plug a phone charger or lamp into the same outlet to confirm it has power. Wall outlets controlled by a light switch are a surprisingly common cause of a monitor that 'stops working' overnight.

When to Call a Professional

If the camera does not respond after a power cycle with a verified working adapter and outlet, the internal power circuit has failed. Contact eufy support for a replacement under warranty.
