I have sticking mine in my Trustfire TR001 with a penny on the plus end, but only when I am to lazy to pull out my hobby charger.
Erik, has that been giving you pretty decent and consistent charges? If that will work, I’ll just pass on getting another charger and just use my TR001 as well.
Alright - Just got my TF Flame 26650, and it doesn’t seem to fit well enough to charge in my TF TR-001. Is it because my TF 26650 is protected? I’m assuming so. Boo.
