After looking around some, I'm not sure there are primary 18650's. I also don't really see the motivation for a primary here. You haven't said if you want to save money, weight or what. Is the goal to throw them away when you're done? Like /u/cosmic_butter_cpu said, a solar charger with some rechargeables would be the best option. Here's a smart adapter which is commonly bought with solar cells (if you look at the "commonly bought with" section).
I got this solar charger. 23000mAh. So far I've charged 3 gopro batteries, one VTC4, and my iphone and the 100% charge light on the unit hasn't even turned off. This thing is awesome so far.

Then I got this 18650 charger. Works well but it took 3 hours to charge one battery. And when I checked it, the battery was at 4.22 volts. Kinda makes me nervous but I'll keep an eye on them.

I has two other Xtar chargers and they're amazing. So I trust the company.
