## Questions & Answers

**Q: What is the distance between the usb c and the on/off switch?**
A: About 4" (10cm)

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

**Q: Does this work with the raspberry pi 3?**
A: No, it will not work with pi 3, this is type c power supply,   pi 3 need micro usb power supply.

**Q: Can i use it to quick charge my samsung phone.**
A: 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.
