Wall-outlet surge cover with 1680 joules, 5 AC outlets, 4 USB ports and a Protected light that shows the circuit is alive.

Check price on Amazon

Pros

• 1680 joules of surge protection with a Protected indicator light
• ETL certification stated
• 5 AC outlets with 2.1 inches of space between them
• Screw fastens the unit to a duplex outlet so it stays put

Cons

• Works on duplex outlets only; GFCI outlets cannot be fastened to the wall
• Only 5 AC outlets, the fewest in this group
• No extension cord; it must sit at the wall outlet
• USB-C port is not Quick Charge 3.0 and does not support 9 to 22V charging

Detailed Review

The listing states 5 AC outlets with 2.1 inches of space between them, 4 USB ports, 1680 joules of surge protection, a Protected indicator light, and ETL certification. The screw at the middle fastens the unit to a duplex outlet, and the listing warns that it works on duplex outlets only and cannot be fastened to a GFCI outlet. The spec table lists a depth of 0.01 inches, which does not match a plug-in extender, so treat the listed dimensions as unreliable. The warranty is 12 months as listed, with a 30-day return.

Who it's for: a desk or a bedside table where the gear sits near a duplex outlet and the unit must stay put. Who should skip it: anyone with GFCI outlets, or anyone who needs a cord.

Its Solar Score of 9.7/10 comes from performance 30/35, build 21/25, value 21/25, safety 8/10 and warranty 3/5: 83 of 100 points, placed on our 9.2 to 9.8 scale.

Numbers side by side

These specs are rated by the maker and quoted from each listing on 15 November 2026.

Where the points went

The Solar Score weighs performance, build, value, safety and warranty. For a surge protector, safety means the certifications and protections the listing actually names; a protector that states no certification scores zero on that line, whatever its joules. Only the Addtam strip states a concrete warranty term, at 12 months; the other protectors state no concrete warranty term. How we pick explains the weights.

Every total is translated into a figure between 9.2 and 9.8 with a linear formula; ranking by points and ranking by score always agree.

How to choose the best surge protector for electronics

Start from joules, then count outlets

Joule figures here run from 900 to 5000. The SUPERDANNY strip states the highest at 5000 joules, while the Addtam strip states 1080 joules. The QINLIANF extender states 1680 joules and the YISHU strip states 900 joules. Outlets run from 5 AC outlets on the Addtam strip and the QINLIANF extender to 13 AC outlets on the SUPERDANNY strip, with 8 on the YISHU strip. USB ports add 4 on each protector: the SUPERDANNY and Addtam strips state 2 USB-C ports each, while the QINLIANF and YISHU picks list 4 USB ports with no split stated. Match the outlet count to the gear on the desk, and see RV surge protector vs power strip for how a strip differs from a wall plug.

Check the cord and the plug shape

The SUPERDANNY strip has a 6.5 ft cord with a 45° flat plug, and the Addtam strip has a 6 ft cord with a 45° flat plug, while the YISHU strip has a 6 ft cord and the QINLIANF extender has no cord length stated. The SUPERDANNY strip adds screws and a drill template for wall mounting, and the Addtam strip adds 2 holes on the back for wall mounting. A flat plug matters behind a desk pushed close to the wall, and a wall-mounted strip keeps the outlets within reach without taking desk space. For the RV side of the same problem, see best surge protector for travel trailer.

USB charging: what each strip gives

The SUPERDANNY strip gives 2 USB-C and 2 USB-A ports with PD 20W charging, so phones and tablets charge from the strip with no extra adapter. The Addtam strip gives 4 USB charging ports with 5V/3.1A and 15.5W in total, and smart charging delivers up to 5V/2.4A per port as the device demands. The QINLIANF extender and the YISHU strip each list 4 USB ports with no split or charging figure stated, so a buyer who charges from USB should weigh the SUPERDANNY or Addtam strips first. All 4 protectors pair USB charging with AC outlets, so a phone, a tablet and a laptop can share the same strip.

Read the safety lines before the warranty lines

The SUPERDANNY strip states 8-fold safety protection against overloads, short-circuits, overheat, over-voltage, over-current, surges, ground faults and open flames. The Addtam strip states overload protection and 3 surge protection circuits: TVS, MOV and GDT. The QINLIANF and YISHU picks state no certification or protection feature. Warranty terms are thin: only the Addtam strip states a concrete term, at 12 months, and the SUPERDANNY strip gives a warranty description with no unit attached. A strip with no stated warranty still protects the gear plugged into it; the warranty term only sets what the maker stands behind after a surge.

Match the protector to the setup

A workbench full of gear suits the SUPERDANNY strip, with 13 outlets, 4 USB ports and 5000 joules, plus screws and a drill template for wall mounting. A home office or dorm room suits the Addtam 2-pack, with 5 outlets and 4 USB ports on each strip and a 6 ft cord. A small desk with no cord to hide suits the QINLIANF wall extender, with 5 outlets and 4 USB ports. A desk that needs 8 outlets suits the YISHU strip, with 4 USB ports and a 6 ft cord. Beyond these 4, the more options add wider choice: the Nuetsa strip gives 8 outlets with 2700 joules, the Alestor strip gives 12 outlets with 2700 joules, the POWSAV strip gives 18 outlets with 2100 joules, the Amazon Basics strip gives 12 outlets with 4000 joules and an 8 ft cord, and the Yintar strip gives 6 outlets with 1680 joules.

Sizing Notes

• Match joules to the gear: the SUPERDANNY strip states 5000 joules and the QINLIANF extender states 1680 joules.
• Match outlet count to the desk: 13 AC outlets on the SUPERDANNY strip, 8 on the YISHU strip and 5 on the Addtam strip and the QINLIANF extender.
• Match the cord to the wall: a 6.5 ft cord on the SUPERDANNY strip and a 6 ft cord on the Addtam and YISHU strips.
• Match USB charging to the devices: 2 USB-C and 2 USB-A ports on the SUPERDANNY and Addtam strips, with PD 20W on the SUPERDANNY strip.
