I tend to go for long-runtime lights over brightness, so my stuff lasts a long time between charges. Even at that, I normally charge whatever I'm carrying with me when I'm at a hotel (someone else's power), and I travel a lot, so by default everything is charged regularly.
The only time I go out of my way to charge everything fully is before a hurricane or other expected outage.
I do recharge my USB battery packs before each flight, but that's a different story. 1x 26800mAh battery powers the iPad for Foreflight and also will power my backup PJ2+ COM radio in an emergency. 1x 26800mAh or 20000mAh battery powers my phone and whatever else people want to bring on board.
