Whether you're running a Raspberry Pi or charging a laptop, the quality of your power supply makes all the difference. Today, we're excited to introduce our best power supply yet, perfect for either task: the $15 Raspberry Pi 45 W USB-C Power Supply.
Efficient regulation
Every Raspberry Pi single-board computer we've ever sold needs flash storage and a power supply. And not just any flash storage or power supply: buying the cheapest SD card or USB wall wart you can find on Amazon is a guaranteed way to have a bad experience. So over time, we started to regulate the accessories offered by our Approved Resellers. We would test resellers' SD cards, to ensure that they had sufficient random-access performance and were resilient against thousands of unplanned power loss events. Last year, we took this to the next level, launching Raspberry Pi-branded A2-class SD cards and NVMe SSDs, which are now the only storage options promoted alongside our computers.
Similarly, Raspberry Pi 4 and Raspberry Pi 5 were accompanied at launch by 15.3 W and 27 W USB-C power supplies. Dominic worked with our ODM partner KTEC and capacitor vendor Panasonic to validate that the design of these products met our aggressive goals for transient response and product lifetime. In the case of the 27 W power supply, we added a custom 5.1 V, 5 A operating mode to give Raspberry Pi 5 headroom to pass an aggregate 1.6 A downstream to power-hungry peripherals.
Power for everyone, power for everything
When you build really high-quality generic products, like USB power supplies and SD cards, interesting things happen. Our colleague Oli tells a story of seeing customers at a Micro Center in North Carolina come up to the Raspberry Pi display and buy just our 27 W power supply on its own: in building the best USB-C power supply for our customers, we'd accidentally built the best USB-C power supply for everyone.
I can certainly relate to this - every USB device in my house is powered by a Raspberry Pi power supply. But 27 W is just a little bit too weedy to rapidly charge my laptop, and so the idea of an upgraded design was born: even better electronics, in (almost) the same form factor, with a longer (1.5 m versus 1.2 m) cable and a suite of new 45 W operating modes, including 20 V, 2.25 A.
All this is available for just $15, compared to $12 for the 27 W version. Raspberry Pi users won't notice a difference: you'll still get 5.1 V, 3 A on a Raspberry Pi 4, or 5.1 V, 5 A on a Raspberry Pi 5. But for everything else, perhaps you've just found your new favorite power supply. Check out our new 45 W power supply today and order from your favorite Approved Reseller.
