@phendrick ooooh, feeling dumb - i thought after they sold the yard they would sell a viola and got kind of excited about that cuz I’ve always wanted one.
If they’re quick, they could claim that’s what they meant -
@RedOx When cranking, the battery puts out some wicked voltage spikes. Also, car 12V ports are notoriously noisy, but I think this is really to indicate it doesn’t explode when one naturally leaves it plugged in.
All OTR Semi’s do, as well as my electric scooter to which I’ve added a cigar lighter type charge port. I’ve seen many USB adapters state they run on 12-24V systems, and I use them. Since you’re reducing the DC voltage output, it almost doesn’t matter what your DC input voltage is as long as it’s over 5V.
Or maybe brain damage is distorting the truth into what I want to believe.
@stinks yeah seriously! Why the heck is this thing $22? I saw the item, started to read the blurb, thinking, “Nice, a cheap 7 port hub for my car.” Then, it turns out to be far more expensive than better looking units on ebay and amazon.
Actual product feedback: I think making it like a conference table setup is certainly a choice. One against the desires of those who wish to tame their cables. If the knights of the round table need to charge their phones, though, they’re covered.
Just common sense says you can get an actually useful Anker unit or other similar for not much more that doesn’t randomly spread the ports all over and has much higher current and more compact design. Unless you all plug in your phones at a round dinner table at night and leave them till morning? Id make the kids park them somewhere else
@therealjrn Sure. Don’t bother calling out China or India. I love plastic bags too. And plastic straws. I readily throw my bottles and cans in the regular garbage because why should I lug a recycling can down the driveway? It all goes to the same place anyway. And no one is gonna take my shit away from me. I do with it as I please. Good luck with your phony virtue signaling.
Here’s the pic I would use if I were stupid enough to buy one of these things. I attempted to use the template with the pic, but my photo apps are failing me so I gave up since I now have to pay bills and get to work lol.
Meh misplaced the decimal point. Should be $2.20
Let see the specs one more time:
Input Voltage: 24 VDC
Total Power: 44 Watts
Max Output Voltage: 5 VDC
Max Current per Port: 2.4 Amps
Max Total Current: 8.8 Amps
We’ll ignore the BS Efficiency note, its either from the wall supply and therefore irrelevant, or it does apply to the charger making it even weaker that it is now.
Lets help the idiots who make BS claims a bit.
BASIC EE101 V=IR and P=IV that means Voltage is equal to current times resistance and Power is equal to voltage times current.
So if I can have a MAX power of 44 Watts, then 44/5= 8.8 Amps. So far the specs line up.
BUT WAIT 2.4A max per port, say what? 7 ports * 2.4 = 16.8 Amps.
SO If you plug in all 7 devices, you will get 1.25 Amp per port (8.8A/7 ports). You can only plug in 3 PORTS to get 2.4 A per port.
So the max value of this item really is $22/7 *3 =$9.40
Flat out a ripoff, not even a meh item, just a ripoff.
Put one up that has an inductive charger, 7 ports supporting a full 2.4A each @ $22 and thats a meh deal.
Before STL won the cup that pic may have been pretty accurate. Now that they have won EVERYONE has been a life long fan and ticket prices have increased because everyone wants to go to the games. Phuf!! #firstworldproblems
@medz@tinamarie1974 i live in boston and it still throws me for a minute when we play certain away games and the seats are mostly empty. here we not only go to the regular season games but also the preseason, the practice, and the ahl games lol.
I think the confusion lies in the way the specs are listed. What it means is, yes, each port can use 5v @ 2.4 amps, but only 3 ports (3 x 2.4 amps = 7.2 amps) can draw that amperage, since 8.8 amps can’t be exceeded. If more ports are used, the amperage per port is reduced, because the system does not produce more than 8.8 amps. It’s a common mistake, one manufacturers hope you will make, because it makes the item seem capable of carrying more amperage than it actually can.
8.8 amps total is 8.8 amps maximum. I’m aware of the per port limitation of 2.4 amps, that’s why I showed the math in the original comment. I was showing why the description was incorrect. It said EACH PORT COULD USE 2.4 AMPS. They can, but not simultaneously.
I’m well aware of the relationship between volts, amps and watts. My point only addressed that 7 ports could not simultaneously use 2.4 amps, because that is a total of 16.8, which is greater than 8.8, at least in the traditional mathematics that I was taught. I’m sure quantum math can probably have it equal to any number, but I don’t have a quantum calculator, either physical or mental.
I don’t see varying degrees of rightness here. I think we can all share the right prize, except for my misreading your post… I’ll take a demerit for that. What’s wrong is the description. Or at least poorly written. We can be friends and have a virtual beer together. Even bad copy meh. I love meh, anyway.
