Some of these listings state a surge figure and some never mention one. The line below compares only the ones that do, on the single number they publish. The rest are counted, measured, and left off it.

TESSAN Surge Protector Power Strip, 5 ft.The left end of the line. The listing still publishes a figure, and that is the whole difference between this strip and the unrated group further down the page.
SUPERDANNY Flat Plug Surge Protector, 10 ft.Low on the line and long on cord: the listing states 10 ft. If the outlet is well away from the stand, this is the one strip here that states a rating and still reaches on its own.
Yintar Surge Protector, 6 ft.Middle of the line on a six-outlet body. A stated figure on a small strip is the combination the unrated six-outlet strips below do not offer.
Anker Power Strip, 5 ft.Second from the right, and the only listing in this group that names TUV. Same outlet count as the strip to its right, fewer stated joules, a shorter stated cord.
ALESTOR Surge Protector, 6 ft.The far right of the line. The listing pairs that figure with 12 outlets and 4 USB ports, which is the other reason a strip this size ends up behind a screen wall.
Not stated
These listings state outlets, ports and cord length and never mention surge energy. There is nothing to place on the line, so nothing is placed.

Core job
Turn one wall outlet into enough sockets for the whole wall, and state plainly what protection, if any, comes with them.
Subgroups
Surge rating stated
The listing publishes a joule figure. That figure is what the line compares, and it is the only thing the line compares.
Surge rating not stated
Outlets, ports and cord length are stated; surge energy is not. These are power strips on this site, and the word protector is not used for them.
Cord management, not surge protection
An outlet cover with an extension cord attached. Its listing states no surge protection of any kind, so it sits on its own.
Buying order
Count the sockets the wall needs, including the strip's own plug. The count rules out more products than any rating does.
Measure from the wall outlet to the spot the strip will sit, along the path the cord will take. Do not buy on cord length before this.
Decide whether you want a stated joule figure at all. If you do, work only inside the group that has one and ignore the rest of the page.
Look at the plugs you already own. Wide power bricks decide how many of the sockets on a strip you can actually reach.
Buy once. If the count came out larger than one strip holds, the answer is a bigger strip or another outlet, never a second strip on the end of the first.
Skip these
A strip bought to solve a reach problem. Reach is a measurement, and the fix is a longer cord or a different position.
A second strip to plug into the first one.
A strip chosen on joules alone when your plugs are wide bricks that will cover four sockets between them.
Anything sold as an outlet cover when what you wanted was protection. If the listing does not state it, it is not there.
A replacement for a strip that took a hard hit, bought later. Replace it when it happens, not when you get round to it.
Category cautions
Stop
Never plug a power strip or surge protector into another power strip, surge protector, or extension cord.
Stop
Never plug a heating appliance into any product on this page. Heaters, kettles, irons and hot plates go directly into a wall outlet.
Note
No product on this page is described here with a load figure. What may run at once is decided by your equipment and your wiring, and those numbers are printed on the equipment itself.

Surge protection not stated
Read firstThe listing describes an outlet cover with an extension cord and states no surge protection of any kind. It is a way to keep a cord flat against a wall. It is not a surge protector, and nothing on this site treats it as one.
