Cannot recommend these. I like Anker products but there's a problem with this particular one. I bought 8 of these during a sale last year and have had half of them RMA'd because I could only get 5 volts out of the USB-C ports, and the USB-A ports would intermittently just turn off. At least two of the replacements are doing the same thing and I haven't had time to test the others.

300joule is bare minimum to be labeled as a surge protector but offers practically zero protection. Small electronics require 1,000 to 2,000 joules surge protection. TV and other large electronics require 3,000 to 4,000 joules protection.

Kind of a common misconception. The Joule rating is more a rating of how long this thing will last/how many surges it can mitigate before dying. A 300 will lose protection significantly faster than 3000. There are a few benefits to having a larger number (can better help mitigate a particularly nasty spike) but for the most part a 300 and 3000 will protect the same against most spikes. The 300 will just die quickly. The clamp voltage is a better measure of how well a protector will protect against any single strike -- often not advertised on these pages.

I have to agree. There is something about their "power strip with USB charging" products. Almost like they're just buying from another company.

LOL, why bigger ones need more protection? Or the other way around?

As far as I remember, they never were UL listed.

This is accurate but clamping voltage also doesn't really matter that much.

The real thing that matters is if it's UL listed (or equivalent) so the thing doesn't burn down your house. The second most important thing is if it is the shape and configuration you want because that's really why you're buying this thing.

The reality is that electronics don't start malfunctioning until surges of 1200v+ and don't start failing in some cases until 1500v+. Surge protectors, even the shitty one slime this l, will have 1200v surge ratings.

And surges just aren't that common that high anyway. One paper suggested once a year at best.

I agree as a fellow anker fan. There is something wrong with this model. For some reason, when we plug this into a particular outlet on an older house, it shorts a part of the house. No other surge protector, no matter how cheap, has done this over the years. Works fine in the office though.

Anker is now self-certifying. For instance it recently de-certified all iPhones informing owners that iPhone internal battery charge controller has been deactivated and the only way to protect their phone from overcharging overheating and burning up is to buy the new Anker Nano charger with screen animation.
