Review: Works Well with Raspberry Pi 4 Model B - Works great with Raspberry Pi 4 Model B. I like the included switch if I want to turn them off without having to unplug them. Review: good for RPi 4 and 5 - 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. ## Features - 【Stable & Reliable 20W Power Delivery】Outputs 5V 4A (20W max) to prevent undervoltage warnings; specially tested and optimized for Raspberry Pi 4 Model B (1GB–8GB) to ensure smooth performance even under heavy load. - 【Convenient Built-in ON/Off Switch】Easily power your Pi on or off without unplugging — extends cable and port lifespan, perfect for frequent use in projects, kiosks, or desktops. - 【Extra-Long 5ft (1.5m) Cable】Provides greater flexibility for placement; ideal for makers, hobbyists, classrooms, or home labs without restricting movement. - 【UL Listed Safety Certification】Meets strict safety standards with over-current, over-voltage, and short-circuit protection; works worldwide with 100–240V input — peace of mind for you and your devices. - 【Broad Compatibility】Perfect replacement or backup charger for Raspberry Pi 4, Orange Pi 5/5B, and other USB-C devices requiring stable 5V 4A power (not compatible with Pi 5's higher power needs). - 【Premium Build & Long Warranty】High-quality materials for durability and low heat; backed by iUniker’s customer satisfaction guarantee — contact us anytime for support. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B097P2NLVH | | Amperage | 4 Amps | | Best Sellers Rank | #107,136 in Computers ( See Top 100 in Computers ) #910 in Computer Power Supplies | | Brand | iuniker | | Built-In Media | Cable, Charger, Adapter | | Color | Purple | | Compatible Devices | Raspberry Pi 4 Model B 8GB/4GB/2GB/1GB | | Compatible Phone Models | Raspberry Pi 4 Model B | | Compatible Power Plug Type | Type C | | Compatible devices | Raspberry Pi 4 Model B 8GB/4GB/2GB/1GB | | Compatible phone models | Raspberry Pi 4 Model B | | Connectivity Technology | USB | | Connector Type | USB Type C | | Connector type | USB Type C | | Current | AC | | Current Rating | 4 Amps | | Customer Reviews | 4.6 out of 5 stars 530 Reviews | | Enclosure Material | Fireproof material | | External Testing Certification | UL Listed | | Frequency Range | 50-60Hz | | Included components | Cable, Charger, Adapter | | Input Voltage | 240 Volts | | Item Weight | 0.16 Kilograms | | Main Power Connector Type | 2 pin | | Manufacturer | iUniker | | Mfr Part Number | AUB097P2NLVH | | Model Number | XSG-0503500HUS | | Mounting Type | Wall Mount | | Number of Items | 1 | | Number of Power Levels | 1 | | Output Current | 4 Amps | | Output Voltage | 5.25 Volts | | Portable | No | | Power Plug | Type A - 2 pin (North American) | | Power Source | AC | | Special Features | Short Circuit Protection | | Special features | Short Circuit Protection | | Specification Met | UL | | Total Usb Ports | 1 | | Unit Count | 1.0 Count | | Wattage | 20 | | Wired Charging Connector Type | USB Type C | ## Product Details - **Amperage:** 4 Amps - **Brand:** iuniker - **Colour:** Purple - **Compatible devices:** Raspberry Pi 4 Model B 8GB/4GB/2GB/1GB - **Compatible phone models:** Raspberry Pi 4 Model B - **Connector type:** USB Type C - **Included components:** Cable, Charger, Adapter - **Input voltage:** 240 Volts - **Special features:** Short Circuit Protection - **Total USB ports:** 1 ## Images ![iUniker 5V 4A USB-C Power Supply for Raspberry Pi 4, 20W Charger with ON/Off Switch, 5ft Cable, UL Listed - Compatible with Pi 4 Model B (8GB/4GB/2GB/1GB) & Orange Pi 5/5B - Image 1](https://m.media-amazon.com/images/I/61VUqZukR7L.jpg) ![iUniker 5V 4A USB-C Power Supply for Raspberry Pi 4, 20W Charger with ON/Off Switch, 5ft Cable, UL Listed - Compatible with Pi 4 Model B (8GB/4GB/2GB/1GB) & Orange Pi 5/5B - Image 2](https://m.media-amazon.com/images/I/71C3pIIYXMS.jpg) ![iUniker 5V 4A USB-C Power Supply for Raspberry Pi 4, 20W Charger with ON/Off Switch, 5ft Cable, UL Listed - Compatible with Pi 4 Model B (8GB/4GB/2GB/1GB) & Orange Pi 5/5B - Image 3](https://m.media-amazon.com/images/I/61TLlkHcPNL.jpg) ![iUniker 5V 4A USB-C Power Supply for Raspberry Pi 4, 20W Charger with ON/Off Switch, 5ft Cable, UL Listed - Compatible with Pi 4 Model B (8GB/4GB/2GB/1GB) & Orange Pi 5/5B - Image 4](https://m.media-amazon.com/images/I/61zNtHzREiS.jpg) ![iUniker 5V 4A USB-C Power Supply for Raspberry Pi 4, 20W Charger with ON/Off Switch, 5ft Cable, UL Listed - Compatible with Pi 4 Model B (8GB/4GB/2GB/1GB) & Orange Pi 5/5B - Image 5](https://m.media-amazon.com/images/I/61jI8JY0NaL.jpg) ## 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. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Works Well with Raspberry Pi 4 Model B *by B***L on 9 July 2026* Works great with Raspberry Pi 4 Model B.
