If you use 18650 batteries, you could also just grab a Nitecore F1 charger/powerbank and then throw a few more batteries in your pack.
It can be used as a charger(ideal in the car to top batteries...

I have both an Anker and a Samsung unit here, both 10K, both last well, bulky but one unit will run LED camp lights for two to three nights and one charge on my phone.
