World’s Smallest (unofficially?) DC Power Station – 5cm × 3cm
This compact power station was born out of the need for quick, reliable 3V or 5V power without the bulk of a bench supply. Powered by a CR123 battery and built around the TPS61023 boost converter, it delivers up to 1A at 5V or runs for hours at lower current.
Designed for portability and convenience, it features onboard voltage regulation, an LED indicator, and jumper-pin outputs for easy connection. Ideal for small spaces and quick prototyping, it’s now one of my most-used tools—simple, efficient, and always within reach.
