NTONPOWER 2-Prong to 3-Prong Adapter Surge Protector

NTONPOWER's adapter-style surge protector converts old two-prong outlets into six grounded three-prong sockets plus two USB ports while protecting devices with a 2100-joule rating and a 10-foot flat extension cord.

Older homes often have ungrounded two-prong receptacles that limit modern electronics. This NTONPOWER power strip plugs into a polarized 2-prong wall outlet and expands it into multiple grounded outlets and USB chargers, adding reach with a low-profile 10-foot flat cord. Built with surge suppression, a resettable circuit breaker, and flame-retardant materials, it is designed to make retrofit power safer and more convenient without rewiring.

How does this power strip work with old two-prong outlets?

The unit accepts a polarized 2-prong input and provides six three-prong AC outlets and two USB charging ports, so you can plug grounded devices into previously non-grounded sockets. It does not create a true earth ground where none exists; it adapts the plug form and provides surge protection and spacing for multiple adapters.

• Plugs into polarized 2-prong wall outlets
• Six widely spaced three-prong AC sockets for bulky adapters
• Two USB-A ports for direct device charging
• Useful for retrofitting older properties without rewiring

What safety features protect my electronics?

This surge strip includes a 2100-joule suppression rating to absorb voltage spikes and an integrated 15A resettable circuit breaker to trip on overload. The housing uses high-temperature flame-retardant material, and the unit is ETL listed and FCC certified for safety and EMI compliance.

• 2100J surge-protection rating to reduce spike damage
• Built-in 15A circuit breaker for overload protection
• 1382°F flame-retardant material for safer operation
• ETL listed and FCC certified components

Will the 10-foot flat cord and rotating plug fit tight spaces?

The flat, low-profile main plug rotates 180° so it fits behind furniture and in narrow gaps where standard plugs won’t. The 10-foot flat extension cord uses a thick copper conductor for efficient power delivery and less heat build-up, giving you flexibility to reach distant or awkwardly placed outlets.

• Low-profile 180° rotating flat plug for slim spaces
• 10 ft flat cord reaches distant outlets and hides easily
• Thick integrated copper conductor for improved efficiency
• Concealable under baseboards or behind furniture

How many devices can I run and what fits the outlets?

The strip has six widely spaced AC outlets that accommodate larger power bricks without blocking neighboring sockets; it also offers two USB ports for phones, tablets, and other USB-powered gadgets. It’s suited for living rooms, bedrooms, home offices, and entertainment centers where multiple devices are used simultaneously.

• Six AC outlets spaced for adapters up to about 1.75 inches wide
• Two USB-A ports for direct charging without extra adapters
• Ideal for TV setups, chargers, monitors, routers, and speakers
• Mounting holes let you attach it under desks or on walls

Who is this for: This NTONPOWER surge protector is aimed at homeowners, renters, and operators of older properties who need modern charging and surge protection without replacing existing two-prong receptacles. It’s a practical solution for students in dorms, people living in older apartments, or anyone wanting extra outlets and USB ports in tight or hard-to-reach locations. If you need grounded-style outlets, organized power for multiple gadgets, and a long, flat cable that tucks away neatly, this unit offers a ready retrofit option.
