GeeekPi USB-C Power Supply UK Plug for Raspberry Pi 4 With On/Off Switch,5V 3.6A Type C PSU with Micro USB Adapter for Raspberry Pi 4B/3B+/3B/Orange Pi 5 /5B /5 Plus

Setup: Raspberry Pi 4 running Home Assistant If you’re using an old phone charger or standard USB adapter to power a Raspberry Pi 4, this power supply is an essential upgrade. What Solved My Issue: Eliminated Underpower Crashing: I had been using an old iPhone charger for about a year with no obvious issues. However, as I expanded my Home Assistant setup with more integrations and plugged in additional USB accessories, the Pi started randomly crashing—especially during system updates. Switching to this dedicated 3.6A supply instantly resolved every stability issue. Ample Current Headroom: The Raspberry Pi 4 is notoriously power-hungry, particularly under heavy load or with attached USB peripherals. The 3.6A output delivers clean, stable power that prevents low-voltage throttles and crashes. Convenient Inline Switch: The built-in physical power switch is a great touch. It saves you from constantly plugging and unplugging the cable from the wall or the Pi’s delicate USB-C port whenever you need a hard reboot. Bottom Line: Don't make the mistake of assuming a standard phone wall charger is enough for a Raspberry Pi 4 once you start putting it through its paces. This GeeekPi power supply is rock-solid, well-priced, and eliminates power instability completely. Highly recommended!

This power supply works perfectly with my Raspberry Pi 4 and feels very solidly built. The 5V 3.6A output keeps the Pi running smoothly even when I’ve got extra peripherals connected. It’s nice not having to worry about voltage drops or random reboots anymore. The on/off switch is a brilliant touch — no more unplugging the cable every time I want to power down the board. The cable length is just right, and the included USB-C to Micro USB adapter is really useful for my older Pi 3 as well. I also appreciate that it’s properly certified and has built-in protection features for safety. It runs cool and stable, and the build quality feels much better than cheaper alternatives I’ve tried. Overall, this is a great, well-made power supply for any Raspberry Pi setup. Works exactly as described and makes powering the Pi much more convenient. Highly recommended!

I recently bought this for my raspberry pi 3b+ as the supply I had was giving a low voltage error causing the system to run slow and caused multiple errors. This supply has fixed that and now it runs better than ever. It's a USB-c connection for Rpi 4 and onwards but also comes with a Usb-C to micro USB adaptor making it perfect for my raspberry pi 3b+. Definitely recommend this product if you are in need of a new power supply.

Works as expected but the plug sometimes is too easily disconnected (e.g., when cleaning around the cable). Also, maybe a bit too bulky considering more modern alternatives.

I bought this power supply for a Raspberry Pi 4 board. The packaging contains the power cord, with a really useful switch embedded, and a USB C terminal. A micro-USB adapter is provided, increasing compatibility with previous models. It appears small and compact, all made with black plastic. The plug has no grounding. The output current is clean and stable, even for prolonged use, providing the correct power source for a Raspverry Pi board, making it suitable for a stable and consistent use of the board. Good value for money, given the low price.

I don't really know why Raspberry Pi don't make it clear just how hard it is to find a good power supply. They say any 2.4A 5V charger will do for the Pi 3, but let's be honest, it's not true, most of the plugs that say they're 2.4A on them and even the ones I've tried that say 3A on them only seem to peak around that but aren't able to provide it full time and it's just impossible to figure out which cables are actually going to make the cut either. You can get a good sturdy looking cable but it's impossible to know how thick the actual wires, terminals and solder points are inside without cutting it open. This supply is listed as a peak of 3.6A and appears to be doing the trick. I've plugged this into my Pi3 (using the included adapter to convert from USB-C to Micro-USB and immediately the low voltage warnings stopped and my Home Assistant instance's random intermittent failures of various automation etc seem to have vanished. I think I'd be happy to try this with a Pi4 also (though I'm already set on that front). However, the new (at time of writing) Pi5 I might have to check again as I recall they've said its requirements for peak usage may be more greedy than the 4 so do check first if that's what you're going for.

This GeeekPi Raspberry Pi 4 power supply is exactly what I needed. It delivers reliable power to my Pi 4 without any issues. The standout feature for me is the inline switch – such a simple but incredibly useful addition. Being able to turn the Pi off without unplugging it is a real time-saver and makes things much more convenient, especially when testing or tinkering with projects. Overall, it’s a solid, well-made power supply, and I’d highly recommend it to anyone using a Raspberry Pi 4.

Exactly as needed and described. Worked straight out of the box for a Raspberry Pi 4B, where the previous power supply had blown. Love the on/off switch on the cable - means you don't need to completely unplug to do a full reboot or power down. Quality is good, a little expensive but worth it for the additional features.
