Thank you for confirming that 18w PD shows as "fast charging", I was asking how many watts S10+ can suck in over PD.
I think the phone detects how much power it needs. Most phone won't take more than 18w. Even if you use a 30w. It will only take 18w max

Two (possibly) dumb questions:

1) How do I find the max wattage at which my device can charge? Like, where would I be looking on a spec sheet, what would this be called?

2) What's the difference between a charger like this that has the small USB-C port vs a regular USB-A port and using a USB-A to USB-C cord?

I have a qc 3.0 wall charger for my s8 and it work fine. But when I use it on my s10e it doesn't say fat charge. It seems like not all qc charger are made the same. Since the wall charger that came with the phone is qc 3.0. I try it with a pd 18 wall charger it works as good as the charger that came with the phone. Pd works for s8. S10e. Pixel 3. How ever it doesn't fast charge the OnePlus 6t.
The 6t has OP's proprietary fast charging.

And Samsung has been using PD charging on its phones for a few years now. 18w seems to be the max most phones use. Everyone should adopt PD and say screw Qualcomm on QC. But the only rub is you need Usb-c to usb-c. So to lose quick charge you would then lose any sort of fast charging beyond the standard 5v/2.1a via USB-A.

Is it worth the $5 premium over this 24w Anker unit?

https://www.amazon.com/dp/B01MY9Z...B07H4M4N5V

If all you're charging are smartphones, how much of a benefit is the 42w over the 24w unit?

I think most phones top out at 18w via PD unless someone knows different. So no benefit to you to get greater than that unless you want to future proof for a future tablet or laptop that supports higher standards.

Correct me if I'm wrong, but for this charger you need a USB-c male- to male cable to use the PD slot on the unit? It's got 1 USB and 1 USB-c input, correct?

Also, do high watt chargers like this cause any problems to car wiring? As in, will it fry the wires or cook the electronics?

The one you linked doesnt have USB-C Power Delivery. PD allows for the device to communicate what it's maximum charge can be. For iphones as an example, you can charge at a maximum of 18w (w/ an apple lightning to USB-C cable).

Yep all PD chargers need usb-c to c connector cable. As long the charger and cable is properly certified should minimize the bad scenario. We dealing with electronics, should have number of percentage that it would fail.

Do you know what PD is and how it is different from QC?
Yeah. I just don't have any devices on PD. QC3 is what I'm on...QC4 is basically the same as PD if I remember, but hasn't been adopted much yet. Just think....PD/QC4 is USBC to USBC. I think the biggest issue people will see will come from cheaply made batteries. QC4 is supposed to read whatever data is available and I'm not sure if it can sense heat, but that is an issue with even QC3 on most thin packs. The thinner the pack, the hotter it will get when quickly juicing up or discharging.

I can already tell that my HTC battery life has significantly degraded over the past 6 months and it's likely because the charging cycles are so short with QC. You can assume devices without replaceable batteries are going to fast-track how disposable they are. I'm hoping these technologies keep moving forward, but wonder if we're going to see any advancements in battery tech. Li-ion still has so many shortcomings, despite its ability to quick charge.

What about this one? Only 2$ more with USB c and 2 sockets. Looks pretty good. I want this for the dash cam and wireless charger
In theory sounds good.

If you occupy all four ports with devices that draw the maximum current, you will be blowing both fuses non-stop; the fuse in the 12V USB charger and the fuse in the factory harness.

Remember, your current 12V outlet outlet will be tied to other stuff in the car, that will draw current. Remeber to replace the car fuses with QUALITY auto fuses. Don't cheap out w/ el cheapo Amazon/eBay/Harbor Freight fuses. You will regent such a purchase b/c these fake fuses will NOT blow when it should, protecting your factory wire harness and attached components.

Only a direct line to the vehicle 12V battery, will you be able to see the maximum output for this 12V USB charger. I am NOT aware of ANY auto maker who does this. It really wouldn't cost them much at all, but they save pennies to maximize profit.

My car has a 120v receptacle (plug) rated for 300w built right into the center console, so I seriously doubt a 12v plug-in 42w car charger is going to be an issue for any modern vehicle.

Not sure why all vehicles don't have 120v plugs in them seeing as how it makes it possible to just use any 120v plug-in home charger as a car charger. No need for dedicated 12v car chargers... just use the same 120v chargers in the car or at home.... saying that, my vehicle also has no less than (4) 12v sockets so I also have several nice seldom-used dedicated 12v car chargers all thanks to SD!
