Description
Here we have the latest VAMO's!!! Both the V4 and V5 with OLED displays!
Very cool in its own right with its modular design. Can be used a mini with a single 18350 or a full size mod with either (2)18350's or a single 18650! Very cool indeed!
Here's the deal on these new versions. V4 is the V2 body (smooth with a flat top cap) but with the V3 chip and display (OLED). The V4's we have in stock are in colors of Blue and Purple/Pink.
The V5 is all the same as the V4 but adds the removable top cap of the V3 which is slightly slanted/beveled with pips. The V5 come in Black Chrome and Stainless.
Select your model and then your color in the drop down.
Come in soft felt storage bag.

Instructions:
1. Press the large button 5 times to turn the unit on
2. Press and hold down the "-"button more than 3 sec to display the Battery voltage
3. Press and hold down the + button more than 3sec,to display the resistance
4. The +/- buttons will change the voltage in 0.1v increments or the Power in 0.5w increments depending on the output setting.
5. Press and hold down the + and - buttons at the same time to enter the Menu. Once in the menu the top right or + button will advance thru the menu and the top left or - button will change that menu setting. There are only 3 function settings in the Menu.
Menu functions:
Menu 1: Hold down both +/- buttons and it enters at Menu 1 and says Power/Voltage. Use the left button to set to either Voltage or Power output. Power output is beneficial in that regardless of your atomizer resistance, the unit will hold constant Power setting for the same vape. You forget about voltage as the unit adjusts that behind the scenes to hold the Power constant.

vaping. You can choose Power(voltage if set from menu 1), Resistance, or Battery. If set to power it will show your setting in Watts (or Voltage if output set to voltage) during
vaping. Resistance will show the Atomizer resistance, Battery just shows the current charge of your battery.
Menu 3: Once in menu from holding +/- press top right or + until you get to Menu 3 and it will say LCD On/Off. This menu function just allows you to turn the OLED on or off during
vaping
Low Voltage/Short Circuit Protection - display shows "LO-V":
