AI Verdict
This 45W USB-C brick delivers the exact 5V/5A profile the Raspberry Pi 5 demands to run at full power, making it a mandatory buy for Pi enthusiasts and tinkerers.
The Raspberry Pi 5 requires a highly specific 5V/5A power profile to unlock its full 1.6A USB current limit. This CanaKit supply hits that exact spec while adding up to 45W of headroom for other PD devices. It completely eliminates the under-voltage warnings that plague standard 5V/3A phone chargers.
If you need more reach, look for the CanaKit version that includes the inline PiSwitch, which adds about 6 inches of length, or buy a dedicated USB-C extension cable.

Pros
- Delivers the exact 5V/5A (27W) profile required to prevent the Pi 5 from throttling USB port power to 600mA
- Doubles as a 45W fast charger for phones and laptops with PPS and Super Fast Charging support
- Includes a built-in noise filter to ensure stable voltage during heavy CPU loads
- Runs significantly cooler than cheaper generic adapters even when overclocking the Pi 5
Cons
- The attached cable is only 4 feet long, which limits desk placement
- The power brick is physically bulkier and heavier than the official Raspberry Pi 27W charger
- The cable is permanently attached to the brick, preventing you from swapping it for a longer one
Dimension Scores
Delivers the exact 5V/5A 27W profile the Pi 5 needs to unlock full 1.6A USB current, plus 45W PD for other devices.
Includes a built-in noise filter for stable voltage, and users report zero coil whine.
Features a thick insulated cable and heavy brick, but the non-removable cable is a slight knock.
The 4-foot cable is permanently attached and too short for many desk setups.
Best For
- Powering a Raspberry Pi 5 with multiple USB peripherals like external NVMe SSDs or hard drives
- Overclocking the Pi 5 without triggering under-voltage warnings
- A single travel brick that can power a Pi 5 and fast-charge a Samsung Galaxy phone
Not Recommended For
- Setups where the wall outlet is more than 4 feet away from the Pi
- Users who just need a basic 5V/3A charger for older Pi 4 or Pi Zero models
Watch Out For
- Short 4-foot cable — you'll likely need an extension cord or the PiSwitch version to reach a desk-mounted Pi.
- Non-removable cable — if the USB-C connector frays or bends, the entire power supply becomes e-waste.
- Bulky footprint — the brick is large enough that it might block adjacent outlets on a standard power strip.

What Buyers Say
The biggest surprise with this CanaKit supply is that it actually outperforms many high-end laptop chargers when paired with a Pi 5. Because it specifically supports the rare 5V/5A power profile, it prevents the Pi 5 from artificially capping USB port power to 600mA. Users consistently report that it runs cool even during heavy overclocking sessions. The permanently attached 4-foot cable is a major pain point for desk setups. Many buyers ended up buying the version with the inline switch just to get an extra six inches of reach.
“Finally a power supply that actually gives my Pi 5 the full 5 amps it needs without throwing low voltage warnings, but I really wish the cable was 6 feet instead of 4.”
Common Praise
- Eliminates under-voltage warnings completely on the Pi 5
- Allows the Pi 5 to power external NVMe drives and SSDs without crashing
- Runs significantly cooler than the official Argon or generic power supplies
- Thick, heavily insulated cable feels durable
Common Complaints
- The 4-foot cable is too short to reach from a floor outlet to a desk
- The power brick is heavy and takes up a lot of space on a power strip
- The cable cannot be unplugged from the brick
- Costs slightly more than the official Raspberry Pi 27W charger
Ownership Tips
- The thick insulation on the cable makes it slightly stiff and hard to route tightly around case enclosures.
- It successfully triggers 'Super Fast Charging' on Samsung Galaxy phones, making it a great dual-purpose desk charger.
- The brick's weight means it can easily fall out of loose or older wall outlets if plugged in horizontally.
Frequently Asked Questions
Will this power my Raspberry Pi 5 at full speed?
Yes. It provides the exact 5V/5A (27W) profile the Pi 5 needs to run without throttling USB power.
Can I use this to charge my phone or laptop?
Yes. It supports standard USB-C Power Delivery up to 45W, including PPS and Super Fast Charging for smartphones.
Does this work with the older Raspberry Pi 4?
Yes, it is backwards compatible with the Pi 4. The Pi 4 will only draw the 15W (5V/3A) it requires.
Is the USB-C cable detachable?
No. The 4-foot insulated cable is permanently hardwired into the power brick.
Why can't I just use my 65W laptop charger for the Pi 5?
Most high-wattage laptop chargers don't support the specific 5V/5A profile. They usually max out at 5V/3A, which causes the Pi 5 to limit power to its USB ports.
Buying Guide
When buying a power supply for the Raspberry Pi 5, total wattage doesn't matter as much as the specific voltage and amperage profile. The Pi 5 strictly requires 5 Volts at 5 Amps to unlock its maximum performance and power external USB drives. Most standard phone and laptop chargers, even 100W ones, only output 3 Amps at 5 Volts. If you use one of those, your Pi will throttle its USB ports to save power. You need a supply explicitly rated for 5V/5A like this one.
5V / 5A (27W) Output
This is the exact 'language' the Pi 5 speaks. Without 5 Amps at 5 Volts, the Pi restricts power to its USB ports, meaning your external hard drives might not spin up.
45W Power Delivery (PD)
Think of this as the charger's ability to adapt. While the Pi only takes 27W, the charger can negotiate up to 45W for hungrier devices like laptops or fast-charging phones.
Built-in Noise Filter
Electronic noise can cause micro-fluctuations in power. A noise filter acts like a shock absorber, ensuring the Pi gets a perfectly smooth stream of electricity to prevent random reboots.
Alternatives
If you need a longer cable or a smaller footprint, look for the official 27W power supply designed specifically for this single-board computer, or a modular GaN charger that explicitly lists 5V/5A support.
