Flat Plug 20 FT Long Extension Cord - Ultra Thin 11-in-1 Power Strip

Our review of the Flat Plug 20 FT Long Extension Cord finds it best suited for people who need to charge many devices from a single distant outlet while keeping furniture flush to the wall. The standout reason to buy is its combination of a 20 ft extra long, 0.12 in flat cord and an ultra thin 0.31 in flat plug head that hides behind sofas, beds, and nightstands without creating a bulge. In practice it turns a single wall socket into a neat, multiport charging station for home, office, or dorm rooms.

Key Features

• 11 in 1 configuration: Eight AC outlets and three USB ports (including one USB C) let a user charge up to 11 devices at once without blocking adjacent plugs.
• 20 ft extra long cord: The extended length reaches distant or hard to access outlets so a desk or entertainment center can be positioned away from the wall.
• Ultra thin flat cord and plug: The 0.12 in flat cord and 0.31 in slim plug head run along walls or under carpet without a noticeable bulge, reducing trip hazards and allowing furniture to sit flush.
• 45 right angle plug design: The angled plug creates space for another plug below it and helps the power strip fit in tight locations behind furniture.
• Dual USB types: Two USB A ports at 2.4A and one USB C port at 3A detect devices and deliver optimal charging for phones, tablets, and accessories.
• Built-in surge protection: A 900J surge protector with overload, short-circuit, and over-current protection plus a reliable switch helps protect connected electronics.

Who It's For

This power strip is ideal for students setting up dorm rooms, homeowners arranging living room or home office equipment, and workshop users who need a long reach to a central outlet; the long cord and slim plug are especially useful where furniture must sit close to the wall. It also suits anyone who needs a mixed array of AC outlets and USB chargers in one tidy unit.

Those who need outdoor power, weatherproofing, or industrial-grade surge protection should look elsewhere, since this unit is intended for indoor use. Buyers who require multiple high-amperage appliances on every outlet should verify device power needs against the strip's protections before relying on it for heavy loads.
