I’ve got an old Motorola AMPS phone around somewhere that has a charging cradle that will fit either the whole phone or the battery on its own. Most commercial two way radios still work like that, I wish they would still make phones like that too.
The dual laptop batteries are handy too. I’ve got a Thinkpad T480 and it can hot swap the external battery. The high capacity battery lasts so long that you rarely need to swap it, but if you use the slim batteries, you will need a couple to get through a whole day. Unfortunately, that’s the last Thinkpad model that can hot swap batteries.
I prefer to use FOSS software. There is a risk of getting malware from pirated software. Even if there is no malware, commercial software usually has lots of tracking and telemetry anyways.
