Worth noting that if you use all 3 USB ports at once, that the USB-C caps at 20W and the two USB-A ports caps at a *combined* 10W.

Edit: Thanks for updating the title!
Yes. This is what I do. My MacBooks are good for all day use and I simply charge them with 30 watt at night to full. Even power hungry ones because they are napping
Even when I am using the Pro14 that usually has the 90watt charger, 30w will keep some juice flowing and if I keep the screen less than full brightness, it will maintain battery level just fine too.
I DO WISH these damn chargers just come with all USB-C instead of usb-A mixed with usc-c cuz now I have to use a adapter as I've pretty much switched all to usb-c other then stupid logitech camera or dongles that are still just USB-A. like wtf Logitech
I'm going to be pairing this with my INIU 45W adapter, which can also handle 2x20W.

(I paid around $16 for it if you want to wait for a deal. It works well and supports PPS).
My laptop can draw about 96W, but as long as i'm not playing AAA games, 45W is more than enough.

USB 1 and 2: 500 mA @ 5V = 2.5 Watts (amps * volts = watts)
USB 3: 900 mA @ 5V = 4.5 W
That's why high-wattage devices like CD burners needed to plug into two USB ports.
10 W for two USB-A ports combined is the max you can get. The phone/tablet chargers which delivered higher wattages weren't standard USB-A. They typically used an extra-long plug which would mate with higher voltage contacts, to deliver higher power if you used that charger, that cable, and that device.
USB-PD (often used on USB-C) delivers higher power by negotiating with the device to deliver power at a higher voltage. (The amperage is limited by the diameter and length of the wire.)
Seems like a good unit.

The reason cd burners used two was because they had to assume the output was the minimum since most people won't know what their ports are capable of.
