It does take everything that I have 18650-wise, in the light. The crappy nuon brand protected 18650 that is long and fat works fine, the tail cap is ingenious for keeping it small… Both those other lights will make you happy too. I have been on a quest for a good AA light that is below $20, but I keep coming back to the Thrunite Archer…. Give us a short review when you get yours if you have time.
Still practicing patience for These two lights HERE and HERE.
