@hamchallenge I operate entirely from battery most days, and never have "range anxiety" — but then I usually operate near or at QRP out in a park. But also, even when I bring the 100W radio out into the park I have more than enough power for a day of operation without stress.

I have internal batteries in one rig, several sizes of LiFePO4, a USB-C PD power bank with "trigger boards" for 12V and 15V, mains chargers, and a 100W portable folding solar panel with charge controller. The diversity here is driven not by functional requirements; it's about playing with toys.

I'm designing a complete overkill power distribution box just for the fun of it, which will allow me to distribute power from solar and multiple batteries to multiple devices, including USB power for phone or tablet for logging, or a fan for keeping cool during the summer. It's ridiculous and unnecessary, but I've been having fun designing it.

@hamchallenge My usual setup involves a suitcase with 2 pcs 18Ah LFP4s in parallel, along with some 3D printed bulkhead connectors. The suitcase acts as a makeshift desk #HC36S. I don't operate much from home, so these 6 hours were my whole day of operating.

I was surprised only 3 DXpeds were active, but a fourth DX, the ITU HQ was lurking on 18MHz. #HC07S. Working 10+ DXCCs is rather easy in FT8 from Europe, when you're being chased in #pota #HC37S
