I just got this in the mail. the car plug works good, but the wall plug does not work. the passthrough blinks but no vapor,
Sameeee
In that case yours does not have the battery and is 5 volts. You'll need a supply current of at least 1 Amp, preferably 2 Amps.Mine has the battery - no rectangular box - just a usb cord with a permanently attached e-cig.
The one without the battery will need enough to power the passthrough at 5 volts and most computers, light duty AC chargers/adapters, and DC adapters/chargers (for the car) won't do that. The output of the charger/adapter needs to be a least 1 amp (1000mAh) but 2A (2000mAh) is preferable.
