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. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Excellent Power Supply *by S***M on October 17, 2025* Works as expected. Nice having a switch to turn off the Pi. ### ⭐⭐⭐⭐⭐ The power supply works well nice location of the switch *by G***Y on September 11, 2025* So far out of the box the power supply works flawlessly there is no AC leakage into the DC circuit and the power supply on for a couple of hours and it still works fine. NO HUM TRANSMITTED FROM POWER SUPPLY ### ⭐⭐⭐⭐⭐ good for RPi 4 and 5 *by G***G on January 9, 2026* I purchased this to build a mobile power supply for my mobile RPi-powered media server. This is fed from a 12v battery backup with pass-thru power. The idea is to have enough reserve power to power the server overnight without using vehicle battery power. So far, all is well. I did decide to use CasaOS to support docker images for the various media servers and this has worked out well. I have two 2TB solid state drives for media and they draw very little idle power. ## Frequently Bought Together - iUniker 20W 5V 4.0A Power Supply for Raspberry Pi 4/ Orange Pi 5&5B, UL Listed Type C Power Supply with ON/Off Switch for Raspberry Pi 4 Model B 8GB/4GB/2GB/1GB[UL Listed] - Raspberry Pi 4 Model B 2019 Quad Core 64 Bit WiFi Bluetooth (4GB) - Geekworm for Raspberry Pi 4 Aluminum Case, Heavy Duty Passive Cooling Metal Case/Housing with Heatsink Pillar Compatible with Raspberry Pi 4 Model B Only-Black (P173) --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.lk/products/338633987-iuniker-5v-4a-usb-c-power-supply-for-raspberry-pi](https://www.desertcart.lk/products/338633987-iuniker-5v-4a-usb-c-power-supply-for-raspberry-pi) --- *Product available on Desertcart Sri Lanka* *Store origin: LK* *Last updated: 2026-05-13*
