20W 5V 4.0A Power Supply for Raspberry Pi 4/ Orange Pi 5&5B, Type C Power Supply with ON/Off Switch for Raspberry Pi 4 Model B 8GB/4GB/2GB/1GB

Great power supply for raspbery pi 4 upwards. Has USB C type connection and a switch for easily turning off your pi. Suitable current rating for the Rasperry pi to avoid any on screen power warnings.Not to users the switch just turns off the DC side, unplug from the wall to fully isolate the power supply.

as the headline says - this just works great. Raspberry Pis are notorious for being picky about the PSUs they'll work with, mostly due to the Pis current draw. This unit is fine - it just works.I'm running a Home Assistant Pi off one, I plugged it in maybe 2 months ago, and haven't given it a second thought- which tells you all you need to know!

Like any one with a full size Raspberry Pi, you'll know the need for a decent power supply to avoid issue under heavy loads.This handy supply provides a beefy 20W output which is ideal for this, the addition of the power switch allows a convenient way to power on/off the system without yanking away at the board all the time.I imagine it would also be suitable for other duties where you need plenty of power delivered over a USB-C connector.

iUniker 20W 5V 4.0A Power Supply for Raspberry Pi 4The iUniker power supply comes in a small colour printed box. Inside the box, you will find the PSU in a plastic bag and the output lead is wound and held with a twist wrap.The iUniker power supply case is moulded in hard plastic the two parts are securely fixed together. The three pin plug is moulded into the rear of the unit and the output cable exits from the top through a short rubber strain relief. The unit seems to be well made and nicely finished.The iUniker power supply that I received has a UK standard three pin plug, the earth pin is solid plastic so I have to assume the unit is properly insulated. The body of the unit has the UKCA mark, which is an appropriate type approval here in the UK. There is a generous length of lead coming out of the PSU with an on/off switch close to the end which is fitted with a USB-C plug. Output of the unit is rated at 5 volts 4 amps.I have the iUniker power supply connected to a Raspberry Pi 4 using the Linux operating system and running Octoprint which, in turn, controls a 3D printer.I have had the iUniker power supply / Raspberry Pi 4 setup running for a few days and so far it has run like a dream. The iUniker power supply gets warm to the touch after running for a while and the on/off switch is a handy extra when it comes time to start it all running.I am pleased with the iUniker power supply and I am very happy to recommend it.

The iUniker 20W 5V 4.0A Power Supply is a perfect replacement for my Raspberry Pi 4 setup. Its Type-C connector and 4.0A output ensure stable and reliable power delivery to my device. The addition of an ON/OFF switch adds convenience, allowing me to easily control the power supply. Whether I'm using a Raspberry Pi 4 Model B 8GB, 4GB, 2GB, or 1GB, this power supply meets all my requirements. With its compact design and efficient performance, it's an essential accessory for any Raspberry Pi enthusiast.

I am unable to fully test this item, but first impressions are favourable. 5V @ 20W (4A) is more than adequate for most microprocessors. It says on the packaging that it is for the Raspberry Pi, but I'm using it with an Arduino Nano ESP32, one of the new generation of Arduinos that have moved from the old micro USB to a USB-C connector, and it works fine.There is a useful in line switch in the cable so you don't have to pull the plug out if you need to power down the micro.I have some slight reservations, none of which are giving problems at the moment.The device is welded shut, so, without destroying it, I cannot examine the build quality and design.There is a CE mark on the packaging, but not on the device as far as I can see.Stress relief in the cable could be better, There is only a short, stiff relief where the cable exits the main body of the device and there is none either side of the switch. This may cause problems in the future.Very minor detail, the image on the packaging shows a device with what appears to be an American 2 pin plug which might cause some initial confusion as it is fitted with the correct UK 3 pin one. I hope that it's marking as double insulated is correct as the earth pin is solid plastic.

Works just as well as the official charger in my opinion.I don't get undervolting messages, nor do I have any other issues.Considering the asking amount versus the original, I can certainly recommend.

USB C power supply so Pi 4 or later.I recently picked up a Pi 4 for my cinema and running Pgenerator for calibration purposes as it was faster, more powerful and allowed extra functionality over my Pi3.I'd missed the USB C update (obvious really) and couldn't use my previous power supplies. Finding a USB C brick from my collection of phones and gadgets was a bit hit and miss and the Pi's are notorious for working, but throttling back if under powered.This worked nicely and adds the sorely missed power supply switch function as well.Appears far eastern but to German specs.
