Clamping power is 800/800/800 - not great for sensitive electronics.
This is let through voltage. Also quite high for this spec. I tried chatting with the company to get the clamping voltage but the rep says it's not listed for this particular model which probably means it's quite high as well.
For about $10 more you can get this one from the same company that lists clamping voltage at 150v

For anyone concerned about clamping voltage, unless you're willing to spend 2-3x more on a great Tripp Lite ISOBAR[amazon.com] where it's 150V rated, all these consumer ones all protect against incredible large surges only. And to be honest, is anyone really buying these to protect against surges or simply to get more outlets - see below for the best mix I think of specs and price.
These I found rebadged units to be the best price/low-clamping voltage (330V) with high Joules. Curious if anyone knows any units that's even better. btw, Monoprice sells the same rebadge unit too:

Also questions answered on the Amazon listing page say clamping is 150
You're right, tho, that my main use for surge protectors is as a power strip for more outlets.
Interesting website! Love that I can sort and filter to find the best one. I think some manufacturers are using their soft clamping rating as the UL's 'hard' (aka true) clamping rate.
Clamping voltage is the maximum voltage allowed to pass through the circuitry to the connected equipment when tested with the UL VPR (Underwriters Laboratories Voltage Protection Rating) test surge. 330 volts is the lowest rating allowed by the UL and the rating must be stated on the unit if anyone is curious what their existing surge protectors are. The lower the number, the better. Other allowed ratings are 400, 600, 800, and 1000. Some manufacturers use a rating called "let through voltage" to present appearances of superior performance or I believe to say what "clamping" is in words the average person could understand without a google search, but UL does not validate this terminology.

I've had trouble figuring out the real definitions of these two terms as well. Some websites say they're the same thing, some say otherwise.
It doesn't seem to be standard and different manufacturers don't always use the terms in the same manner.
At least what makes sense to me from a quick search (I'm definitely no expert) is that clamping voltage is the voltage that the surge protector starts working or when the MOV transitions to form a short from power to ground, bypassing your electronics. Let through could be either the max voltage the surge protector lets through once clamped, or the average voltage in this event. Again, I've found conflicting definitions.
One thing that is the same everywhere I've looked is that lower voltages in these two specs is better
This surge protector is amazing. I have the same one and it saved my computer from getting fried back in September when a lighting strike blew the nearby transformer tower. I honestly can't recommend Tripp Lite any higher because of that.

I think your links are the same for the two 12-outlet models? I want one with USB ports but it looks like both are just the same Amazon Basics model.
Thanks for the very helpful write-ups guys. I had no idea about clamping voltage. I looked up the one used for my TV (Belkin 12-Outlet Pivot-Plug Power Strip[amazon.com]) and it looks like it has good clamping ratings but the one being used for my gaming laptop is not (Belkin 12-outlet[amazon.com]).

I ended up ordering 3 of the other one you linked. Definitely worth the extra money to protect kids computers
Thanks

Anyone know if the Wirecutter's version of the Trip lite is a good option for home theater protection?

Thanks for the catch, I'll correct the post too, but the one with the USB ports is the above from APC.
