Determine how many devices you need to charge at once. Products range from three to nine ports, balancing AC and USB options.
Choose a model with enough ports to avoid frequent swapping and keep your space organized.
Cord Length and Design
Cord lengths vary from six inches to five feet. A longer cord provides more flexibility, while a short one keeps things compact.
Ensure the cord length suits your room layout to avoid tripping hazards or clutter.
Surge Protection
Surge protection is vital for sensitive electronics like computers and TVs. Models with 900J protection offer better safeguards against power spikes.
Prioritize surge protection for valuable devices to prevent potential damage from electrical surges.
Thickness and Profile
Ultra-thin profiles allow furniture to sit flush against the wall. This is crucial for maximizing space in tight rooms.
Look for models under 0.5 inches thick to ensure they do not block the outlet below.

Always choose certified products to protect your home and devices from unsafe electrical equipment.
Mounting Options
Wall-mountable strips help secure the device out of reach of pets and children. Mounting holes or adhesive kits facilitate installation.
Consider mounting options if you want to keep the extender off desks or floors permanently.

Modern devices require USB-C for fast charging. Older USB-A ports may not provide enough power for laptops.
Check port specs to ensure they meet your devices' charging speed requirements effectively.
How to Use and Care for Your Flat Outlet Extender
Insert the flat plug directly into your wall outlet without forcing it. Ensure it sits flush against the wall for safety.
Plug your devices into the AC or USB ports as needed. Avoid overloading the strip by checking total wattage limits.
