Cheap, efficient, USB-C Power Supply?

[Zer0_C00L]

So I'm looking at getting a few '12v' power supplies, USB-C is my preference, and I'll adapt to 4mm Lenovo, Dell, 12v Barrel Jack etc.

Wondering if anyone has any suggestions for something that will be power efficient for things like a NAS & Router. They're all pretty low power draw should be under 45w, but if there is something efficient in a higher power range I'm all ears.

Since I'm in Australia, I'd prefer stuff on like AliExpress over say Amazon. Or specific bands etc.

Please and thank you.

Have a look for USB-C PD decoy triggers on aliexpress. you can set them to request 12v from usb-c fast charger. you'll also then need to find a usb-c PD fast charger/module and these will need 24v+ input rather than 12v.

Look for PD-capable adapters that uses GaN transistors.

Check the used market for USB-C GaN laptop chargers... Dell, HP, Lenovo, etc.

AE is not my first go-to place for a lot of reasons, but your mileage will vary.

USB-C GaN laptop chargers... Dell, HP, Lenovo, etc.

This is exactly the type of information I was hopping for. Any specific suggestions, like Dell 65w systems that look like this... Etc?

My alternative if AliExpress was/is unreliable was to pick up a bunch of used Dell/HP/Lenovo Power bricks and keep whatever are low power and flog off the rest.

You can buy USB-C adapters from I guess 45W to charge smartphones to 60-165W to charge laptops.

Do you want one with multiple PD outputs? Just one? Check out offerings from this site: GaN Charger Deals, Coupon Codes, Prices, Reviews - OzBargain

I buy used stuff on FB Marketplace mostly.... choose a seller that is local to you.
