I've noticed the leaking as well....filled a Vortex and set it on my desk last night and this morning between a quarter and a half of the liquid had leaked out from the battery end onto my table.
I tried this Vortex on my 5V passthru for only a few puffs so I am wondering if the 5V is just too much for the adhesive they use to seal the bottom.
