I carry a Brunton battery+PV panel combo, but they seem to have stopped selling them. Have two: one is a rectangle with PV on one side and the other is cylindrical with a flexible PV that rolls out into a large panel. The second one recharges more quickly.

My kit is migrating to rechargeable devices, including headlamp, InReach and phone (for connecting to InReach). The camera doesn't field-recharge, although such cameras do exist.

For a night or two it's hard to make a case for field recharging but for longer trips it justifies itself pretty quickly, because it's essentially unlimited on the back end with no spare batteries needed.

Cheers,
