iRasptek Raspberry Pi 5 Power Supply UK Plug, 27W 5.1V/5A USB-C PD Power Adapter for Raspberry Pi 5 （White）
Packs a punch with 5A charging at 5.1v which is great for powering my raspberry pi with a high power load, is built with high quality materials and provides a stable power source.
This 27W power supply can provide enough power for the Pi5, but also for any peripherals connected to it as well.
It can put out 5Amps at 5.1V allowing it to very comfortably support the Pi. The cables are soldered in, so if it is damanged to affects the whole adaptor. But it seems secure enough to last a long time.
Listed Price when I reviewed it: 13.99

This power supply for the Raspberry Pi 5 is robust and reliable, delivering stable power without triggering low voltage warnings, even under heavy loads. It offers good voltage regulation across a range of devices, and its integrated USB-C cable is durable and well-constructed. While slightly bulky, it remains manageable and doesn’t obstruct other outlets. The unit gets warm during extended high-power use but maintains performance. Although it lacks some convenient features like an on/off switch or a removable lead, it proves to be an excellent power supply for the Raspberry Pi and other USB-C devices.
This power supply for Raspberry Pi 5 does the job well. It’s rated at the correct rating and I didn’t get the low power warning that you can get on poorer quality supplies (or when you try to use a phone charger).
It’s bulky without being too large and should fit more sockets without obscuring other sockets or switches.
The cable is a good convenient length too.
I ordered this to see whether it would work with a Pi4b and I was not disappointed. Works perfectly fine. No stability issues that I can tell. (Note: Using Pi as RetroPi for PSX, etc. and with 256GB SSD attached via USB).
Considering this works just fine with a 4b, I will certainly be on the lookout for more.
This Raspberry Pi power supply comes in retail packaging, and you’ll find the power supply inside the box in its own resealable plastic pouch.
The power supply has a good quality feel to it, and it has a good amount of weight to it so it doesn’t feel cheap. The plastic casing has a smooth texture to it and is easy to grip when removing it from a socket. The is a tensioner as the cable comes out of the main supply which stops the cable from kinking when pulled tight so you shouldn’t have any problem with broken cables inside.
I used this to power my RaspberryPi 5 as I mainly use it for emulation, so it does need a good power supply. I ran some high-end emulators with no crashing or freezing so it definitely supplies enough power that the Pi needs when under heavy loads. There were no warnings on the screen telling me that it wasn’t receiving enough power. This can power any USB-C device and I’ve also used it on my Egret mini arcade machine which is also set up for emulation. These are known to restart or freeze without a decent power supply that can provide enough power. The machine ran flawlessly when powered by this power supply so it’s highly recommended.
PI 5 PSU
This looks like a good quality phone UBC Charger, but it is kicking out 5amps!! So is powerful to run the Pi5 with accessories and under heavy load. A lower/cheaper PSU will not be as reliable and could burn out. I have had some Pi’s crash because the psu is just not powerful enough. They boot up, but then struggle.
The USB C connection is good quality and a snug fit. The cable is 1.5m so plenty of room from a socket to desk/bench.
As it is for a Pi, I would have liked an inline power switch for convenience.
When it comes to PSUs, I do like them to feel reassuringly heavy, this is certainly heavier than a phone charger, but not too bad, if you are trying to be portable.
Would recommend.
I have no complaints about this PSU, it seems to provide the required 5A as needed by the Pi5, and it doesnt have any issues running a pi5, emulation and an SSD over USB at the same time with no low voltage warnings.
Doesnt get hot and runs nice and quiet.
The only issue really is.. It is currently priced MORE than the official PSU, which makes this a hard sell. If its on a deal, or the price is right at the time you look, Id have no complaints using this, but at a higher price I’d struggle to see why you’d pick this over the official PSU.
I have a Raspberry Pi 4 used as a web server 24 hours a day. I have been using it with a Pi 4 power supply, but have noticed that the supply gets quite hot in use. I wanted something with a little more power that could run cooler and give me capacity to run more peripherals in future.
This supply came in a ziplock plastic bag in a cardboard box along with a warranty registration card. Using the card I was able to get an extended 2 year warranty which was confirmed to me by email.
The power supply itself feels to be premium quality with a strong plastic casing and a thick power supply lead. I have used it to power my Pi 4 and as hoped the power supply only gets very slightly warm to the touch. Needless to say, there have been no low power warnings or issues.
There are a couple of features which my original supply had that are missing on this one.
1) An on/off switch in the supply lead. This is useful if you need to fully remove power from the Pi. Without it, the only way is to unplug the supply lead from the Pi (wear and tear) or unplug the adapter from the mains supply.
2) A removable supply lead connected via a USB plug/socket. This is handy if you want to use the supply with something else, or if the lead gets damaged and needs replacing. That said, 5V/5A USB leads are hard to come by.
Overall an excellent power supply that could be improved further with a couple of modifications.

This power supply, unlike normal USB power supplies has an integrated cable with a USB-C plug on the end. The power supply comes in a retail box indicating that it is specific for the Raspberry Pi 5, however it is not specific at all and will work with any ‘PD’ enabled device.
It will deliver a range of voltages, 5V, 9V, 12V and 15V and various currents up to an output power of about 30W. The cable is quite thick at 3.5mm diameter and has good current handling capabilities, with very little voltage drop if any over its 1.5m length.
I tested the various voltages and currents and found this power supply to be very good and exceeded its specifications with just 0.1 to 0.2 volts drop at all maximum currents. Even at a 5.5A draw, there was only 0.2V drop and that was probably from my test leads as these were starting to get slightly warm whereas the power supply cable didn’t show any increase in temperature at all.
Load testing at 5.0A for over an hour only showed a voltage drop of 0.2volts and as mentioned this is most likely due to my test leads. The power supply did get quite hot though, but at 5amps, I’m not surprised, from an ambient temperature of around 33C, after 30 minutes the case was at 55C, but at 1 hour had only increased a little higher to just over 61C, (this would be an extreme use case though).
Overall, this is a very good power supply, very stable and good current handling, it does get a little warm at high currents but that would be at an extreme use. It runs my Pi perfectly without any voltage drop alerts at all and that is with several USB peripherals connected too. Of course, it’s not just for a Raspberry Pi 5, it can be used with most if not all USB-C PD appliances.
