So I have a few 18650 batteries. They are the red AW IMR 18650 2000mah batteries, and also a couple 18350. I'm going on a trip where I'll be without power for long periods of time and need to keep my phone charged too. Since I have more than enough batteries to keep me vaping I was hoping to use them to charge my phone too. Has anyone tried to use their batteries to charge their phones? I've seen a few devices on Amazon and eBay, but wasn't sure if I could use my batteries.
Here's link to a couple of the chargers if anyone is interest.
