About
Most of my products focus on power management and giving makers tools to quickly move their prototypes to production. Power management is often forgotten, but a vital part of creating reliable, trouble free systems. So my products use long life batteries, most can be powered from sources other than USB, and often are compatible with solar power.
Contact me for all your electronics needs from system and circuit design to layout to custom firmware and software development. Partial outsourcing or turnkey. Simple or hard. Standard stuff or something that never has been done before. Let's discuss your project. If it's something I can't do, I may know someone who can.

Excellent product
For LiFePO4wered/Pi+
I use it on a pi4, which is not really supported due to the greater power draw. I haven’t scientifically stress tested it to see just how long it would last, but I once noticed it lasted at least 20 mins. That said, it works great for switching between my anker battery and wall wart.
Only critique I have is that I wish the input power was USB-C instead of micro USB so that I could use only one type of plug.
