TESSAN Flat Plug Extension Cord 5 FT, Surge Protector Power Strip with 4 AC Outlets 1 USB C and 2 USB A Ports

Key features that matter for daily use

Flat, right-angle plug for cramped layouts

The low-profile 0.31-inch flat head plug and 45-degree right-angle design are the centerpiece of this model. If your wall outlet is partly blocked by a couch, bed, desk, or entertainment center, this style of plug is built to help you use that outlet without pulling furniture away as much. Larger adapter plugs also tend to be easier to accommodate thanks to wider outlet spacing and a 3-sided layout.

Power and outlet count for mixed setups

You get 4 AC outlets rated up to 1250W max, plus three USB ports: 1 USB-C and 2 USB-A. This is meant to cover typical desk, bedside, and dorm device clusters, such as phone/tablet charging, laptop power bricks, and small electronics. The stated electrical rating includes 125 volts and up to 10 amps.

Surge protection rated at 900 joules

For electronics you want to protect from unstable power conditions, this strip includes a 900 joules surge protector. It also has short-circuit protection and over-current protection. The product guidance notes that the surge indicator light should remain on when surge protection is working properly, and that if the indicator light goes off, surge protection may have failed.

USB-C plus USB-A charging, with one important caveat

Total USB output is listed as 15W for the USB-C port and guidance indicates USB charging speed can slow significantly (or may cease) when all three USB ports are used simultaneously. If you typically charge one device at a time, this is less likely to be an issue, but it matters for shared workspaces where multiple people plug in at once.

Stability and placement options

Four anti-slip rubber feet help keep the strip steady on a desk or nightstand. There are also mounting holes for a more permanent setup, such as in an office workspace or workshop area.

Pros and cons (realistic buyer-fit)

Who this is best for

• Buyers with tight furniture clearances who need a flat plug that fits behind or near the wall
• Desk, dorm, and bedside setups that need both AC outlets and phone/tablet charging
• People who value surge protection alongside standard outlet distribution

Who should consider alternatives

• Anyone expecting fast USB charging for multiple devices at once, since guidance indicates slowed performance when all USB ports are in use
• Households plugging in multiple high-power appliances (space heaters, large fans, etc.), since overload protection can trigger if you exceed the 1250W ceiling
• Travelers who need cruise ship compatibility, because this model is specifically not intended for that use

Specs at a glance

• Cord length: 5 ft
• AC outlets: 4 (1250W max, 10A)
• USB ports: 1 USB-C, 2 USB-A (USB output guidance notes slowed charging when multiple ports are used)
• Surge protection: 900 joules (with short-circuit and over-current protection)
• Plug type: Type B 3-pin (North American)
• Design: ultra-slim flat head with right-angle orientation, anti-slip rubber feet, and wall-mount holes

Verdict: is the TESSAN flat plug extension cord worth it?

The TESSAN flat plug extension cord is a solid pick if your main problem is outlet access in tight spaces. The flat, right-angle plug plus four AC outlets and mixed USB charging make it well suited to desks, dorms, and bedside areas where standard power adapters would block furniture or create messy cable gaps. The key limitation is USB behavior under load, so if you routinely charge multiple USB devices simultaneously, double-check your typical usage pattern against the stated USB charging guidance and your total AC power needs.

If you want one compact strip that balances space-saving design, surge protection, and everyday charging, this model’s feature set aligns well. If your priority is maximum simultaneous USB throughput, or you expect to run higher-power appliances through the same strip, you may want to look for a different configuration with more headroom or different charging capacity.

FAQ

Can I charge multiple USB devices at the same time?

USB charging guidance notes that using all three USB ports simultaneously can slow charging significantly, or may stop charging for some devices. For best results, charge fewer USB devices at once.

What is the surge protection rating?

This strip is rated for 900 joules of surge protection and includes short-circuit and over-current protection.

How many AC devices can I plug in?

You can use all four AC outlets, but the total output must stay within the rated capacity (1250W max, 10A). Plugging in multiple high-power devices can trigger overload protection.

Is it wall-mountable?

Yes. It has mounting holes for installing on a wall or similar surface, and it also uses anti-slip rubber feet for stable desktop placement.

Is this power strip suitable for cruise ships?

No. It is not suitable for cruise ship use.
