I think every vaper should have a pass-through. God forbid you dont have any batteries handy, you can always plug this into a USB port and get a descent vape. These are also great for the car. Just get a USB to Car Charger adapter (get them at the dollar store) and your good to go. This unit vapes from 3-5 volts depending on which power source you use. Obviously if your plugging it into the wall your going to get the full 5v. The standard 3.7v pass-throughs are usually higher then 9.99 - so having this 5v version is a good deal.
For 9.99 w/ a warranty, can you go wrong?
