@MonoBY 

Thanks for putting up with my off-topic banter and for posting the links.

The Waveshare HAT looks interesting to me. Have you actually used it? My only experience with pogo pins is in NDTE (non-destructive test equipment) where they are very reliable but used only for brief moments   in a static, lab testbed. I wonder about the long-term reliability of their connections in a mobile/portable system out in the field, so to speak.

Hi Kent,

I've been using the Pi Zero with the Waveshare UPS Hat quite often for the last ca. 2 years (almost every day i drive to work) and I had never any problem with the pogo pins. But I never used it on rocky/bumpy roads

The 1000 mAh battery is not very large of course, but it's ok for me. Surely not a solution for long distances. A large powerbank might help out (or a 5V USB port in the car).

But the battery is a standard model with a plug that can be replaced easily (on the PiSugar the battery wires are soldered), an it is held in a safe position.

On the downside, the power drains if you forget to switch the Hat off with the physical power swtch. And there is no easy way to monitor the power of the battery. There's Python code available, but I can't use it on my access device (smartphone browser).
