Product Description
This is the official Raspberry Pi power adapter for the Raspberry Pi 4 Model B, not a generic USB charger. It matters because the Pi 4 needs a specific voltage and current to run reliably — using an underpowered phone charger is a common cause of random reboots or "under-voltage" warnings.
What it does
The adapter outputs 5.1V DC at up to 3A through a USB-C connector that plugs straight into the Pi 4's power port. That headroom above the board's baseline draw is what keeps things stable once you add USB drives, HATs or network adapters — accessories that pull extra current from the same supply.
What's in the box
- Integrated USB-C cable (no separate lead needed)
- UK 3-pin mains plug, ready for a standard UK socket
- Black casing, regulated output for continuous, always-on use
Where it's used
Fine for everyday Pi 4 projects — home automation hubs, NAS boxes, IoT devices, development boards, or classroom computing setups — anywhere the Pi needs to run continuously without power-related instability.
Before you buy
Check your Pi model first: this supply is built for the Raspberry Pi 4 Model B specifically. If you're already seeing crashes or a lightning-bolt icon on screen, a genuine 5.1V/3A supply like this is usually the first thing worth ruling out before suspecting the board itself.

Frequently Asked Questions
Will this work with a Raspberry Pi 3 or older model?
It's designed specifically for the Raspberry Pi 4 Model B; the source doesn't confirm compatibility with earlier Pi models, so check your board's power requirements first.
Why does the Pi 4 need 3A rather than a standard phone charger?
The Pi 4 and any connected USB devices or storage draw more current than most phone chargers supply, and a weak supply can cause instability or under-voltage warnings.
Does it come with a UK plug fitted?
Yes, it has an integrated USB-C cable and a UK 3-pin mains plug, so it connects directly to a standard UK socket.
Is this suitable for a Pi running 24/7?
Yes, it's built with a regulated output suitable for continuous operation.
