## Overview

The CanaKit 5V 2.5A Power Supply is a UL Listed, high-quality adapter designed specifically for Raspberry Pi 2, 3, and 3 B+ models. Featuring a 5-foot noise-filtered cable and a regulated 5V DC output at 2.5 amps, it ensures stable, reliable power delivery even under heavy loads or overclocking, preventing voltage drops and unexpected reboots. Trusted by thousands for its durability and consistent performance, this power supply is the essential upgrade for any serious Raspberry Pi enthusiast.

## Description

2.5A is now a requirement for the Raspberry Pi 3. The CanaKit 2.5A Raspberry Pi power supply / adapter has been specially designed and tested for the new Raspberry Pi 3 and incorporates an inline noise filter for highest stability and reliable operation. This power supply differs from typical standard 5V USB power supplies in the market in that it can deliver a full 2.5A and still output a voltage well within the USB minimum voltage specifications. Standard 5V USB power supplies in the market have a high voltage drop when the full current is drawn from them which may cause the Raspberry Pi to reboot unexpectedly. With this power supply, you can power the Raspberry Pi 3 at full load as well as up to 1.2A across the four USB ports. The power supply still has about 0.5A of output power to spare, so even at the maximum current supported by the Raspberry Pi 3, the power supply is not at its absolute maximum. It is also ideal for use by anyone over-clocking the Raspberry Pi which causes higher power requirements that a lower power adapter may not be able to supply.

Review: Little expensive, works great - I recently purchased the Raspberry Pi 3 B+ Power Supply and I have to say that it has exceeded my expectations. While it was a bit more expensive than some other options on the market, the quality and reliability of this product make it well worth the investment. The power supply was easy to install and works flawlessly with my Raspberry Pi 3 B+. I haven't experienced any power issues or interruptions since I started using this product, which has given me peace of mind knowing that my Raspberry Pi is receiving the consistent power it needs to function properly. The build quality of the power supply is impressive, with sturdy construction and a sleek design that looks great alongside my other tech equipment. It's clear that a lot of care and attention to detail went into the manufacturing of this product. While it might be a bit more expensive than other options out there, the peace of mind and reliability it provides make it worth the extra cost. If you're looking for a high-quality power supply that you can rely on to keep your Raspberry Pi running smoothly, this is definitely a product worth considering.
Review: Powers my favorite pi - Years later still going strong. Needed a few more pis, and looked for the same original canakit power supply I've been using for years, I mean why not, they are darn reliable even if they aren't exactly the cheapest option.

### ⭐⭐⭐⭐⭐ Powers my favorite pi
*by M***S on November 17, 2025*

Years later still going strong. Needed a few more pis, and looked for the same original canakit power supply I've been using for years, I mean why not, they are darn reliable even if they aren't exactly the cheapest option.

### ⭐⭐⭐⭐⭐ It's just right for my application as a DAC/preamp power supply
*by W***M on December 16, 2025*

I wanted a power supply for a modest DAC that was a bit more power than the 10w supply I had at hand, and that [maybe] had a lower noise profile than some used in lighting applications. This appears to meet my requirements since I still can't hear any noise using this device, but I'm getting [I think] a small increase in DAC preamp volume.
