    900W/4A

    Beyond 4 Amps being the most insanely low rating I’ve ever seen on a power strip, 900 Watts would actually be 8 Amps at the 110 Volts dictated by the North American plug on the cord.

      Correct me if I’m wrong, this came from a jaded blue collar emergency worker, but isn’t 8A enough to essentially vaporize a human being in a short time frame?

      That old adage, volts hurt, amps kill, yada yada.

        volts hurt, amps kill

        True, in a sense, but misses some nuance. Current is pulled, not pushed. Volts provide the electromotive force that allows the current to flow in the first place. Considering Ohm’s Law (V=IR), for 8 Amps to be pulled by a human body at 110V, the body would have to provide a resistance of only 14 Ohms.

        A quick search shows humans can range from 1000 Ohms when really wet up to 100,000 Ohms dry. I’m assuming this is just in regards to skin, because another result specified 300 Ohms inside the body. Let’s just look at the 300 Ohms, and we’ll say 8 Amps * 300 Ohms = 2400 Volts. 2400 Volts to pull less current through the body than your average hair dryer pulls at 110 Volts.

        Another way to look at it is a car battery is 12 Volts and has the capacity to provide around 500 Amps. Touching one terminal with each hand won’t kill you. We don’t come close to drawing the 500 Amps the battery is capable of providing, as we’re only pulling 12 V / 300 Ohms = 40 mA at worst (but remember that skin provides extra resistance beyond the 300 Ohms, so really we’d be pulling much less). It only takes a couple milliamps across the heart to kill you, but what little current flows through you is taking many split paths through your body, so only a portion of that goes through the heart.

        Yes it would kill you if it were to flow through you, but it is very low for a power strip, especially one with so many sockets.

    It could have only three outlets and still be shitty.

      They’re not guessing, they’re keeping their picking options open. Sometimes it’ll be vendor A, which makes it either 12 ports. Sometimes vendor B, which makes it either 13 ports. Sometimes vendor C, which makes it with 14 ports. Lol

    It’s like that game where you add elastics around a water melon, but more high stake. Just one more appliance!

    In case this is not obvious: they are great for Internet cafes to plug in many low power devices. E.g. a bunch of laptops, USB-C outlets and devices that will not run simultaneously. Also it’s got a current protector just in case.

      No, it would be horrible for that because it is in one location and would become risky any time it was busy. Plus most of the outlets would be blocked by nearby power plugs.

      If it was intended for a large number of low draw stuff through USB then having a ton of USB plugs would make sense.

      There is a reason that businesses of that type add lots of permanent outlets to plug power strips into.

        The real one (warning, Amazon link) has 10 wall-wart outlets, 12 “regular” outlets, and 6 USB ports. It’s also rated for 1875W/15A like most household circuits in the US.

        Still pretty sketch for under thirty bucks, TBH.
