Powering equipment.

Doing a trip driving home from Alaska (3 week trip in August) Got a Tacoma and a cap tent.

What are you guys doing to power fridges and say cell phones and a tablet at night for movies?

I'll have power a few times in Alaska but the whole trip down through Canada I plan on doing dispersed camping (where able)

I don't really want a noisy generator to recharge a battery pack? Is solar viable? I could run a selinoid off the alternator but that only works when driving.

Sorry this isn't necessary overlanding but I figured if anyone would know it would be you guys.
