Yeah see thats what I wanted to do, I was running a lot of my stuff on a charger but it wasn't worth it. The dollar store sells packs 8 double A's for a dollar and its worth just keeping them close to your core so the cold doesn't sap them and using them as you need them in everything. Plus I have nothing essential running on a battury mostly quality of life items like a radio and mini lamp. I might keep my charger for its cell phone attachment which does make it worth it for my longer excursions in the summer.
I do need to swap my gear over to AA, I need a new mini lamp and a decent AA radio. Maybe I could look for some more light quality of life shit as well. Might just get this actually:
