SHOP SWITCHED STRIPSMost listings throw numbers at you with no context. This guide decodes every spec โ then matches a strip to what you're actually plugging in.
Every legitimate power strip publishes these. If a listing hides one, that's an answer too.
How much surge energy the strip can absorb over its life before it stops protecting. Think of it as a fuel tank for spikes.
The total load the strip can carry. A standard outlet is 15A (โ1875W at 125V). Add up your devices and stay under it.
The thickness of the copper. Thicker wire carries current cooler and safer. Bargain strips quietly use thinner wire.
Not just how many outlets, but how far apart. Wide spacing fits bulky wall-warts without blocking neighbors.
Reach without tension or coiling. Measure the run to the wall before you buy โ too short strains the plug, too long clutters.
Built-in USB saves adapters. USB-C with Power Delivery (PD) fast-charges phones and tablets at its rated wattage.
What surrounds live parts. Metal dissipates heat, resists impact, and won't feed a flame the way thin plastic can.
The safety hardware: a real MOV for surges, a thermal cutoff for overheating, and a resettable breaker for overloads.
A spec only counts if it's verified. Numbers like joules and clamping voltage are meaningful when the strip is listed to UL 1363 & UL 1449 โ see how certification works โ
Tap everything you'd plug in โ and how many. The rule: total draw stays under the 15A / 1875W rating, and under 80% of it for anything running continuously.
TYPICAL DRAWS โ CHECK THE LABEL ON YOUR DEVICE FOR EXACT WATTAGE.
Past the safety basics, these are the differences you'll feel every day โ and the ones bargain strips fake or skip.

SHOP SWITCHED STRIPS
Screw bracket, 3M adhesive, or keyhole โ power off the floor and exactly where you work. Essential for benches and garages.
SHOP MOUNTABLE
Built-in USB-C PD charges phones and tablets without a wall brick โ freeing AC outlets for things that need them.
SHOP USB MODELS
Bulky adapters block neighboring sockets on cramped strips. Wide spacing means every outlet you paid for stays usable.
SHOP SURGE STRIPS
Wrap ears and keepers take up slack instead of leaving it pooled on the floor โ fewer trip hazards, less strain on the plug.
SHOP CORD REELS
An aluminum-alloy shell shrugs off knocks and heat, and a press-reset breaker turns an overload into a two-second fix.

The bottom of the market competes on price by cutting what you can't see. These tells give it away before you buy.
A UL/ETL logo in the listing photos means nothing โ the mark must be molded or printed on the strip itself, with a file number you can look up.
If the listing won't state a joule rating โ or a clamping voltage โ assume there's no real MOV inside. It's a power strip wearing a surge protector's label.
Copper, breakers, and certified MOVs have a real cost. A rock-bottom price is paid for with thin copper-clad aluminum and untested internals.
Gauge is the cheapest spec to print and the most expensive to honor. Silence on AWG almost always means 16AWG or thinner behind a 15A label.
We cut one of each open so you don't have to โ see the teardown comparison โ
For phones, lamps and chargers, 1000โ1200J is plenty. For a computer, TV or AV stack, choose 2000J or more โ higher ratings protect better and last longer, because the MOV inside depletes with every surge it absorbs.
A power strip only adds outlets. A surge protector adds a joule-rated MOV circuit that clamps voltage spikes before they reach your gear. If a listing has no joule rating, it's not a surge protector โ it's just more sockets.
AWG measures wire thickness โ lower numbers are thicker. A 15A strip should use 14AWG copper, which carries a full load without overheating. Bargain strips quietly substitute 16โ18AWG or copper-clad aluminum, which runs hot under the same load.
Avoid it. Every added link raises resistance and overload risk, and daisy-chaining can exceed the first strip's breaker rating. Plug strips directly into the wall โ if you need reach, buy a strip with a longer cord or a cord reel instead.
Until its joule budget is spent โ every surge it absorbs uses some up. That can be years on a clean circuit or months in a storm-prone area. A protected-status light shows when the MOV is exhausted and the unit should be replaced.
No. A 1500W heater alone consumes nearly the entire 1875W rating of a 15A strip, and its sustained draw overheats shared connections. Heaters, kettles, and other high-watt appliances should plug directly into a wall outlet.
Look for a UL or ETL listing mark on the unit itself โ for surge protection specifically, listing to UL 1449. An unlisted joule number is a marketing claim, not a tested rating. CRST displays every certification on the product page, with full certificates available on request.
CRST product pages list these specs in full โ measured and verified. Filter by use case and compare like-for-like.
