Sure, i wouldn't expect significant battery life from a 10440, i'd use an 18650 for battery life, but my 18650 mod is pretty big, you just can't take it everywhere and stealth vaping isn't exactly inconspicuous, especially on a flight. I have a couple of small ego like batteries, slightly bigger, they're 1400mah i think, but they have a stupid led that lights up. I find the alpha unique and intriguing, it differs from all other mods in every single way, either that be styling, switch or liquid container. The 0.5ml ultraLite RES might be just enough to keep you satisfied, but know i'm kind of thinking that the Ultra might a better choice, it's probably a medium size mod, not sure how much bigger it is that the ultralite... hmmm *thinking*
