Since 2020 · surge protector power strips
Twelve outlets, four USB ports and 2,700 joules of surge protection on one strip, with a cord of 6, 10, 15 or 20 feet. Pick the length that reaches your wall outlet, so you never need a second cord to get there.
01Rating plate
The same figures are printed on every one of the nine strips we sell. Only the cord length and the color change.
The same six numbers apply to every length and color in the Alestor range, so the only choice left to you is the reach and the finish.
02Cord length
The cord is the one thing you choose. Every Alestor length has the same twelve outlets and four USB ports, so measure first and let the number pick the strip.
6 ft A desk or a TV stand pushed against the wall, with the outlet right behind it.
10 ft A bed or a sofa a few steps from the wall, or a desk that faces into the room.
15 ft A wall of shelves or a long desk where the only outlet is at the far end.
20 ft A workbench, a garage wall or a craft table across the room from the nearest outlet.
The shortest cord suits furniture that stands against the wall, with the outlet behind it. It is also the one most people put next to the bed, and at 6 feet there is little spare cord to tidy away behind the nightstand.
See the 6 ft stripTen feet covers a sofa with chargers at the far arm or a desk that faces into the room. It is the length for furniture a few steps out from the wall, with enough cord to run around the corner instead of across the floor.
See the 10 ft stripFifteen feet runs the length of a bookcase wall or an entertainment wall when the only outlet sits at one end. The cord follows the baseboard behind the furniture, and the strip lands in the middle where the plugs are.
See the 15 ft stripTwenty feet reaches a garage bench, a craft table or a gaming desk on the far side of the room from the only outlet. With that much cord, the strip can hang on the wall above the bench instead of lying on the floor.
See the 20 ft stripEach of the 4 lengths belongs to the Alestor lineup, with the same twelve outlets on the same 11 inch housing.
03Outlet map
Most outlets on a strip sit close together, so one wide charger brick can cover the outlet next to it. On the Alestor strip the top pair is set 2 inches apart. Put the bulky adapters there, and the ten outlets below stay free for ordinary plugs.
You get this layout on every cord length of the Alestor catalog, from the 6 ft strip to the 20 ft one.
04Surge protection
The 2,700-joule figure is an energy rating for the protection circuit inside the strip. Makers measure it in different ways, so two joule numbers from two brands are hard to compare. What we can show you is what is inside and how the strip tells you it is working.
Protected light. Lit while the surge circuit is working. If it goes out while the strip is switched on, replace the strip.
No surge protector can handle a direct lightning strike, and the circuit protects only what is plugged into this strip. Our guide to joules explains the other figures on a surge protector label and how to read them.
05Three finishes
The finish is the only thing that changes besides the cord. Pick the one that matches the desk, the baseboard or the wall behind the TV.
All 9 versions are part of the Alestor power range, and the page for each cord length lists its finishes with prices.
06Before you plug in
A power strip is built for many small loads at once, and the whole strip shares one 15 A rating, the same circuit it plugs into. Twelve outlets do not mean twelve heaters.
07Questions
Measure the route from your wall outlet to where the strip will sit, along the baseboard and around furniture, then add a foot or two of slack. If you land between two lengths, take the longer one. Six feet suits a desk against the wall, 20 feet a bench across the room. The cord length guide walks through it.
No. CPSC says to plug an electric space heater directly into a wall outlet, never into an extension cord or a power strip, and the same goes for refrigerators and microwaves. The strip is built for computers, TVs, chargers and lamps. Our guide on what not to plug into a power strip has the full list.
The USB-C port gives up to 3 A at 5 volts, which is 15 watts. That charges phones, earbuds, watches and most tablets, but a laptop that wants USB-C power delivery charges slowly or not at all. Plug the laptop's own charger into one of the AC outlets, ideally one of the two wide-spaced ones at the top.
The top two outlets are set 2 inches apart for exactly that: laptop bricks, router supplies, smart speaker plugs. Put the wide plugs there first. The ten outlets below are at standard spacing, so two bulky adapters side by side in those rows can still cover a neighbor.
As long as it stays lit, the protection circuit is doing its job. If the strip is switched on and the light has gone out, the surge protection is not working and the strip should be replaced. ESFI advises using protectors with exactly this kind of light, one that tells you when it needs replacing.
Every length and finish has its own buy button on this site. It opens the strip you picked at our retail partner, where the price is confirmed and you check out. Payment, delivery and returns are handled there too.
08Alestor since 2020
We picked one design, twelve outlets and four USB ports on a 2,700-joule circuit, and made it in the cord lengths people actually measure for. That is why the catalog is short. You choose the reach and the color, and the rest stays the same.
Surge protection
The joule figure is an energy rating, and the surge industry warns that it is hard to compare between brands. Here is how to read the rest of the label.

Measure the route the cord will take, not the straight line, then keep it out from under rugs, doors and furniture. The agencies agree on where it may go.
