Curious also USB-C AA/AAA batteries as well. Has anyone found one brand better than the other. Would rather run a few power banks and less loose AA/AAA batteries.

My Dark Energy Poseidon is 10200 MAH and has served me well for the past 4 years. Nitecore's Carbo 20000 MAH bank claims to be the lightest weight 20k bank in the world at 10.42 oz.- I'm looking hard at getting one.

I also have the Ryno Tuff 21 watt solar panel which, for $35 is VERY hard to beat. Its tough as nails and just plain works. The Dark Energy Spectre 18 watt panel seems exorbitantly expensive ($230- no thanks) for what it is. Maybe I havent researched it enough to justify the cost. Dark Energy is legit though. It claims a weight of 15.34 oz., which seems proportionate in wattage and weight to the Ryno Tuff... given the companies are being honest with their wattage and weight claims.
