Voltage and Watts

The voltage of the Vapor Flask V3 40W is 1 – 9.9V with a variable wattage that can be adjustable from 1.0W to 40.0W. It has an atomizer resistance of 0.16 – 2.0ohm.

Threading

The threading on the Vapor Flask V3 40W is no surprise. It’s a 510 threaded connection with a copper plated brass center pin and adjustable with temperature control function.

Battery Power

The Vapor Flask V3 is powered by two 18650 batteries, which are not included but it can also work with a single 18650, which is convenient.

The Vapor Flask V3 40 Watt Mod does not have a USB port for charging but it is much faster to swap out your batteries than it is to spend hours charging the two 18650 batteries.

How to use the Vapor Flask V3 40W APV

• Fire Lock: Click the fire button five times
• Stealth Mode: From the locked position, hold the fire button and wattage down button simultaneously
• Left/Right Mod: From the locked position, hold the fire button and wattage up button simultaneously
• To adjust temperature settings: From the locked position, hold the wattage up and down buttons simultaneously to access the temperature setting. Then use the up and down buttons to adjust to the desired setting.

Temperature control can also be turned off from by scrolling up past 600F to OFF.

The chip in the Vapor Flask V3 mod will fire both Ni200 and Kanthal builds and the KX-40D will ask you, “new coil up/same down” when you change or install a new atomizer.

You simply press the up button if it is a new coil or the down for the same one.

Safety Features

There are quite a few features on this APV which make it more safe to use. It has short circuit protection, overheating protection, and protection of battery opposite connection.

Like any mod of this type, you should know what you’re doing before attempting to use it.

This is not a device for those new to vaping or beginners and a working knowledge of electronics is helpful.

The temperature control starts working to keep the firing coil below the setting that is best, usually around 450 degrees depending on your build.

You will see the display screen flash the words, “temperature protected” and the chip will throttle back on the wattage and voltage output.

This works quite often when your coil is dry and even when vaping often or chain vaping.

This simply protects the device and doesn’t meant that there is anything wrong with it.

This works great at protecting you from the scorched or dry wick taste.

The Look and Feel of the Vapor Flask V3 40W Mod

The Vapor Flask 40 watt mod comes in a few different colors: black, red, silver, and light blue.

It has a very slick look and feel, but the only drawback is that the grip is a tad slippery.

This isn’t a deal-breaker by a long shot but it does mean that you might want to be more careful when handling it.

Since it is made out of aluminum, it should be quite sturdy though.

The anodized finish does give it a little bit of texture so that helps.

It has a nice, hefty weight to it so that it feels sturdy in your hands but it’s not too heavy to be uncomfortable.

The threaded area looks cleanly built and the buttons have a tactile feel to them rather then being more of a clicker style.

There is one issue with the air flow channels. This does not affect the functionality of the device but it does look just a little “off.”

Between the 510 connection and the top plate, the air flow channels are out of alignment.

However, you will find spacious battery slots that are very well built and do not have an ounce of anodized coating.

Like with the air flow channels, the battery slots do have a difference in depth with the coin slots not lining up evenly by about 1.5mm.

Again, not a big issue but a minor flaw in construction.

Builds to Use

There are a couple of builds you may like to use with the Vapor Flask.
