It transforms a standard outlet into a convenient 3-outlet station without adding bulk.

Its standout quality is the detachable outlet cover. When not in use, the cover hides the outlets completely, maintaining a seamless look with your wall decor. The 3-foot cord provides enough slack to move the strip to a usable location while keeping the plug hidden.

Choose this if you prioritize aesthetics and basic power expansion in tight spots. It works well for lamps or small electronics where USB is unnecessary. The affordable price makes it a low risk addition to any room setup.
Aesthetic Concealment
The removable cover ensures outlets stay hidden when inactive, preserving wall visual continuity.

Buying Guide – How to Choose the Best Flat Outlet Extender
Selecting the right flat outlet extender depends on your specific spatial constraints and power needs. Consider the following factors to find the perfect match for your home setup.
Cord Length
Cord length determines how far you can place your devices from the wall. Longer cords offer more flexibility but may create cable clutter if not managed. Shorter cords are neater but limit movement.
Choose a length that reaches your desired spot without leaving excess slack on the floor.
Outlet Count
More outlets mean more devices can be powered simultaneously. However, higher counts often increase physical bulk. Ensure the outlets are spaced to fit large plugs.
Balance the number of ports with the available space in your room.
USB Charging
USB ports allow direct charging without extra bricks. Look for USB-C options for faster speeds on modern devices. Total wattage per port affects charging speed.
Prioritize USB-C if you need fast charging for phones and laptops.
Surge Protection
Surge protection shields electronics from voltage spikes. It is vital for sensitive devices like computers. Not all flat extenders include this feature.
Check for a Joule rating to ensure adequate protection levels.
Mounting Options
Wall mounting keeps the strip secure and off surfaces. Look for pre-drilled holes or adhesive options. Fixed mounts reduce tripping hazards.
Select a model with holes if you plan to mount it permanently.
Plug Thickness
Thickness defines how close furniture can sit to the wall. Ultra thin plugs are essential for tight gaps. Standard plugs may block the outlet.
Verify the plug depth to ensure it fits your wall constraints.
Safety Certifications
Certifications like ETL or UL ensure electrical safety standards. They indicate the product has been tested for fire risks. Always look for valid marks.
Confirm that the product carries recognized safety certifications before buying.
Aesthetic Design
Color and shape impact how well the device blends with decor. Some offer covers or specific finishes like white or grey. Consider the room style.
Pick a design that matches your wall color for a discreet look.
How to Use and Care for Your Flat Outlet Extender
When installing, ensure the flat plug aligns with the outlet to avoid bending wires. This maintains the thin profile. If using adhesive clips, clean the wall surface for a secure hold.
For mounting, use the included hardware on drywall or wood. Do not place heavy items on the strip to prevent damage. Ensure plugs are inserted fully to avoid sparks.
Clean the unit with a dry cloth to remove dust. Avoid liquid cleaners that could damage electronics. Check periodically for wear on the cord or plug.
Frequently Asked Questions
Can flat outlet extenders block the outlet?
Standard bulky plugs often block the lower outlet. Flat outlet extenders are designed to be ultra thin so both outlets remain accessible. Look for models specifically marketed as flat or low profile.
Do flat outlet extenders work with surge protectors?
Some flat outlet extenders include built-in surge protection. Others do not. If you need surge protection, choose a model with a Joule rating rather than a simple adapter.
How do I hide the cord for these units?
Use cord clips or adhesive channels along the baseboards. Many kits include clips. Alternatively, run the cord under rugs or furniture legs to keep it out of sight.
Are flat outlet extenders safe for children?
Many models include covers or safety designs that reduce exposure. However, active supervision is still recommended. Select models with outlet covers to minimize access to live pins.
Can I use flat outlet extenders on cruise ships?
Cruise lines often prohibit surge protection. Look for travel models explicitly stated to have no surge protection. These are legal for onboard use and safe for standard electronics.
What is the best thickness for these units?
The best thickness allows furniture to sit flush. Look for plugs under 0.3 inches. Ultra thin designs ensure no gap remains between the furniture and the wall.
