What car charger should i get for all my android devices?

I may be charging a range of different devices. Not all at once of course but probably two at a time.

I wanted to know if i should get this 39w charger https://www.amazon.com/gp/product/B01K9MQ8WW/

Or this one. https://www.amazon.com/gp/product/B07H4LH6P7/

The first is 39w and has PowerIQ.

The new model is only 30 watt and advertises PowerIQ 2.0. Is it better to go with the old higher wattage version?

Devices i will be charging including samsung tablets, galaxy s9, moto g4, whatever devices from anyone with me. I am planning on getting two of these as i know i will probably be getting some kind of new device and with all the charger standards out there it is hard to find one that can fast charge each device at the devices fastest possible rate.

I am not sure if this should fall under support or tips?

Specs below, copy / paste from ankers website.

39w version specs
Input:12V/24V Output:3.6-6.5V=3A, 6.5-9V=2A, 9-12V=1.5A

30w version specs

Input: 12V / 24V ⎓ 4A Output: 5V==2.4A/9V==1.67A/12V==1.25A Dimensions: 65 × 35 × 35 mm

Just by the charger with highest output and wireless compatible.

By the way, wired quick charge is not universal, phones like Oppo require VOOC charger, they don't fast-charge with QC2, QC3 chargers.
 
What is the goal and what is the average length of time devices will be on the charger? If it's just to keep the devices going while in the car, then either will be adequate. If you want as quick a charge as possible, I think @lvt is correct in that with multiple brands of devices there will be no universal quick charge, so you'll have to pick your primary device and settle for normal charging on the others.

FWIW plugging multiple devices in at the same time might defeat fast charging. It's been my experience with most of these devices that current is shared across ports. And the higher the voltage, the lower the amperage output. If the charger can't meet the requirements of rapid charging, it steps back to normal mode.
