The description says 4A, the picture says output 3.5A ... Which is it?

Unlike the model in the picture of the advert (XSG-0503500HUS) rated at 5V 4A, I was delivered model XSG-0504000HUS rated 5V 4A. Seems to work just fine with my RasPi 4... and if I plug too much "stuff" into the USB ports (multiple USB web cams, etc.) with the brownout lightning bolt flickering on the screen, I have a separate powered USB port to help with the load.

Does this work with the raspberry pi 3?

No, it will not work with pi 3, this is type c power supply, pi 3 need micro usb power supply.

Can i use it to quick charge my samsung phone.

The Raspberry Pi itself doesn't have negotiation chipsets/protocols for higher power delivery, and this being paired with such devices would be inappropriate for phones or other electronics that aren't designed for higher power delivery without a negotiation chipset/protocol. For modern phones, you should consider a USB-C Power Deliver (PD) charging device. There are other, older, "quick charge" chipsets/protocols in many of USB chargers, but PD is really what you're looking for moving forward. PD charging is what most/many current laptops support as well, you can use a higher rated PD for both, reducing the number of chargers you have to carry around with you. Similarly, it will give you more flexibility for a car charger as well.

NOTE! Will not power Pi 5 -- OK power adapter for lesser models

NOTE that this adapter does not work for the Pi 5 --- It works for the Orange Pi 5. I misread the info, which is on me.Outside of that, the adapter works quite well and I do appreciate the little power switch on the cord. Nice touch!

4A - Worth 4 Stars at the Gate

Pironman 4B 8GB Owner, several in fact. First 5V, 4A offering seen, + On/Off switch, = solid **** rating. All I can hope for is long lasting in Nos Mo King environment. [ - $1.89, = ***** rating ]

Works well for MisterPi!

Works with MisterPi to add an off switch. 100 percent worth the price for the added feature. Basically does 5v 4a power with an on off switch if that's what you're looking for.
