@haydesigner And they might work, and they might have more circuitry than two resistors and a potted-on-board chip. Temu is OK for some things, and better than Wish ever was, but…
@G1 The 24V was a typo, the operating range is 12-24V. (Fixed now) One port adheres to an old “quick charge” standard of 5V/2.4A (12W) while the other has a much higher output rate in conformance with the QC 3.0 standard, IF your device supports that.
I realize that the mediocre writer is just copying specs, but they don’t really make sense, if you get picky.
“Simultaneous output: 3A per port
Total Rated Power/Output: 30W/5.4A”
So it can output 3A per port at the same time, but it’s Rated Output is 3A and 2.4A, split between the 2 outputs, maybe.
It’s all just manufacturer specmanship, but I bet if you measured the max outputs, the QC 3.0 would behave as it’s rated/spec’ed, and the quick charge would drop to 1A max if a QC device was plugged into the other port.
Also, I am not super familiar with the QC 3.0 spec, but battery protection is built into the battery, not the charger. With “quick charge”, if the battery overheats, it shuts off charging (the battery circuitry does this). If it’s close to full charge (~85-90%), it pulls MUCH less current than 2.4A, more like 0.5A or less.
Maybe with QC 3.0 the battery tells the charger to drop from 9V to 5V, for example, but I thought that all the brains were in the battery itself. I am not aware of any feedback loop from battery to charger with the QC 3.0 spec, but I could be wrong.
Yada, yada, yada, guessing and probably bs. Now I probably need to go look up the industry standards for QC 3.0…
@G1 Much of such inconsistency derives from layers of Telephone. The people who wrote the design specs likely were not fluent in English, and technical terminology translates only slightly more cleanly than consumer-assembly directions. The manufacturer who actually produced the item likely just copied the specs forward without attempting to test or verify any of it, and may not have had an engineering staff to vet it anyway. They just assemble to order. The marketing company that contracted for the batch most likely had no one on staff who understood the specs either, so another layer of translational inexactitude got added. End result: mis/dis/non/anti/information.

I beg to differ with “you can’t have enough of this stuff”. I have a case.
@sammydog01 I think in the last irk they gave me the old style and they are not working in my car
@ironcheftoni So I should buy some of these?
@sammydog01 or wait to see if they are in your irk
These are useful and cheap, filling the need for “a purchase” to knock the $10 off the IRK.
Interesting how with the exorbitant and weird irk pricing of previous offers, $29 has been made to look reasonable. We see what you did there …
You can buy these for less than $2 on Temu.com

I don’t have 24V in my car. I’ve only got 12V, which is really about 14.1V when running.
And how do you get 3A out of a 2.4A max port? Slower?
