Detailed Review
GE lists a 6-outlet surge protector with a 20 ft cord of 14-gauge SJT cable, 800 joules of protection, an integrated circuit breaker with automatic shutdown on overvoltage or overheating, twist-to-close safety covers and a space-saving flat plug. The spec table gives 13A, a rectangular body at 2.15 by 5.65 inches and a Limited-Lifetime warranty, and the title states a UL safety listing. The listing also names GE the top brand in the category, a ranking claim we do not repeat.
Who it's for: anyone whose desk sits far from the outlet and wants the longest cord with automatic shutdown. Who should skip it: buyers who want USB charging or a second strip in the box.
Its Office Score of 9.8/10 comes from performance 33/35, build 22/25, value 21/25, safety 8/10 and warranty 4/5: 88 of 100 points, placed on our 9.2 to 9.8 scale.

How we scored them
The Office Score weighs performance (surge rating and cord length), build, value, safety and warranty. For a surge protector, safety means a stated UL or ETL listing, outlet covers, circuit breakers and automatic shutdown. All five list a safety certification or protective features, and four of the five state a warranty term. How we pick explains the weights.
| Product | Office Score | Perf. /35 | Build /25 | Value /25 | Safety /10 | Warranty /5 |
|---|---|---|---|---|---|---|
| GE 20 Ft 800J Surge Protector | 9.8 | 33 | 22 | 21 | 8 | 4 |

Scores run from 9.2 to 9.8: each product’s point total is placed on that range, so more points always means a higher score.
How to choose the best surge protector with long cord
Cord length decides where it can live
Measure from your desk to the outlet before you buy, then add slack. The GE 20 ft strip reaches across a room, the GE 10 ft and IECOPOWER 10 ft cover a desk against the far wall, the Cable Matters 8 ft suits a nearby outlet, and the DEWENWILS 6 ft is for close quarters. Flat plugs on the GE strips, the IECOPOWER and the DEWENWILS let furniture sit close to the wall.
Joules and the circuit breaker
The joule rating says how much surge energy the strip can absorb: 800 on both GE strips, 700 on the IECOPOWER, 500 on the DEWENWILS and 490 on the Cable Matters. Every pick lists a circuit breaker, and the GE 20 ft adds automatic shutdown on overvoltage or overheating. Watch the amperage too: the IECOPOWER is rated 1250W/10A while the others list 15A ratings up to 1875W or 1800W, so check it against your devices.
| Protector | Cord | Joules | USB |
|---|---|---|---|
| GE 20 ft | 20 ft | 800 | None |
| GE 10 ft | 10 ft | 800 | None |
| IECOPOWER | 10 ft | 700 | 2 USB-A, 1 USB-C |
| DEWENWILS | 6 ft | 500 | None |
| Cable Matters | 8 ft | 490 | 2 USB-A |
USB ports and outlet spacing
If chargers eat your outlets, the USB picks help. The Cable Matters strip adds 2 USB-A ports at 5V/2.1A, and the IECOPOWER adds 3 USB ports including a USB-C at 5V/3A max, with 5 widely spaced AC outlets. The GE and DEWENWILS strips keep it simple with 6 AC outlets each and no USB. For a desk full of computer gear, our best surge protector for computer and printer guide compares more options.
Mounting and warranty
A strip screwed under the desk stays put. The GE strips and the DEWENWILS list keyhole slots for wall or desk mounting, and the Cable Matters includes a mounting template. On warranties, both GE strips state a limited-lifetime term, the IECOPOWER states 12-month replacement, the DEWENWILS states 1 year, and the Cable Matters states no warranty term. Pair the strip with tidy routing from our best extension cord for cable management guide.
Setup Notes
- Measure the run from the wall outlet to the desk and buy a cord longer than that distance; a taut cord pulls plugs loose.
- Plug the strip directly into the wall outlet and keep the total load under the listed rating: 1250W/10A on the IECOPOWER, 15A on the others.
- Use the keyhole slots or mounting template to fix the strip under the desk or on the wall, off the floor.
- Check the wire gauge for heavy loads: the GE 20 ft and Cable Matters list 14-gauge wire, the DEWENWILS lists 14/3C SJT, and the IECOPOWER lists 18AWG.
- Keep the strip where you can see the indicator light and reach the on/off switch.
Frequently Asked Questions
How many joules do I need in a surge protector?
Higher is better for absorbing surges. Here the GE strips list 800 joules, the IECOPOWER lists 700, the DEWENWILS lists 500 and the Cable Matters lists 490. All five also list a circuit breaker for overloads.
Can I mount these under a desk?
The GE strips and the DEWENWILS list keyhole slots for wall or desk mounting, and the Cable Matters includes a mounting template. Mounting keeps the strip off the floor and the cord out of the way.
Which of these have USB charging ports?
The Cable Matters strip has 2 USB-A ports at 5V/2.1A, and the IECOPOWER has 3 USB ports including one USB-C at 5V/3A max. The GE and DEWENWILS strips have AC outlets only.
What do the warranties cover?
Both GE strips state a limited-lifetime term. The IECOPOWER states 12-month replacement, the DEWENWILS states a 1-year warranty, and the Cable Matters states no warranty term.
Is a 10-amp strip enough for a desk?
It depends on the load. The IECOPOWER is rated 1250W/10A while the other four list 15A ratings up to 1875W or 1800W. Add up your devices before choosing the lower-rated strip.
