it looks like the quark 18650 body consists of 2 parts.
couldn´t it be more simple?
it looks like it is longer than it has to be. or am i wrong?
anyway: is the the 2xAA head brigher on 18650?
how much longer will be the runtime with an 18650 AW protectet compared to two eneloos?
how effectiv is the quark aa2 on two alkaline aas? what would be the runtime on max?
(thinking about using it while traveling through laos/kambodia/myanmar an i´m not shure if i´m going to take a charger with me. 18650 is for use at home, and on my MTB)
by the way: is it more effective using a single or a double aa light when you only are able to use alkalines?
Think 2 AAs are better than one (power and run time)
18650 will give longer run time. recharging any place in the world is cool.
Is the current 110 or 220 volts in SE Asia? Have you considered a solar charger?
A 2 AA Quark will give you much more than a single AA.
I can't say how a 18650 cell does with a 2 AA Quark head, yet I CAN say I have a 18650 with the 2 CR123 TurboForce head. I thought that would give more power and runtime than 2 AA. The 18650 with a cool white Quark RGB head is another option I enjoy.
The 18650 assembly is not as simple as it would appear because there are three parts not one. in addition to the 18650 tube, there are 2 additional separate "screw end caps".
