Hana Modz DNA 40 Review

The DNA 40 is a temperature protected, power regulated, advanced vape controller from Hana Modz.

It gives 500 mA of charge current through its built in DNA charger, which is micro USB powered.

Of course you’ll get the same features you’re used to such as standard safety features, 40 watts of power, and temperature control.

Along with a floating 510 connection pin and it houses an 18650 battery.

In this DNA 40 review, we’ll look at what sets this apart from similar mods.

What’s New?

Hana Modz DNA 40 (1)The DNA 40 is the first chip for electronic cigarettes to directly measure and limit the temperature of the heating coil during usage.

By preventing the coil from becoming too hot regardless of fluid, wicking or airflow.

This makes it safer to use and prevents a myriad of issues from happening.

You won’t experience dry hits or burnt cotton when choosing to use nickel 200 wire instead of kanthal.

Instead of voltage, the device will display your temperature limit and you can adjust it accordingly to get the best flavor, and of course no burnt cotton or hits that taste dry and scorched.

When the DNA 40 is used with a temperature sensing atomizer, an additional feature called Preheat is activated.

No vapor is produced when the temperature is below the boiling point of the liquid.

Preheat applies extra power until the heating coil is up to operating temperature to shorten the delay between pressing the fire button and generating vapor.

Because the preheat is temperature relatively low, it will not overheat or burn the vapor.

You’ll also find this device has passthrough capabilities, allowing you to vape it while you charge it.

How to Use the DNA 40

Waking up the DNA 40

  1. Simply tap the fire button.
  2. The create vapor, use the same fire button, and to change the wattage, use the up or down buttons which you can click or hold down.

How to change atomizers

  • The DNA 40 used the resistance of the atomizer to calculate the temperature of the heating coil.
  • It continually looks to see whether a new or changed atomizer has been connected.
  • If you are using temperature protection, be careful to only attach new atomizers that have cooled to room temperature to the device.
  • If a new atomizer is attached to the DNA 40 before it has cooled down, the temperature may read and protect incorrectly until the new atomizer cools.

When connecting a new atomizer or disconnecting and reconnecting an existing atomizer, the DNA 40 will prompt to confirm this change.

When you fire the first time, before activating the DNA 40 will prompt “New Coil? UP YES/DOWN NO“.

When you see this prompt, if you have attached a new atomizer, press the UP button. If you have disconnected and reconnected the same atomizer, press the DOWN button.

Safety Features

The Hana Modz DNA 40 has quite a few safety features such as:

  • Overcharge protection
  • Temperature protection

There are also quite a few error messages that will display if you have an error with the device:

  • Check Atomizer: The DNA does not detect an atomizer, the atomizer has shorted out, or the atomizer resistance is incorrect for the power setting.
  • Shorted: The atomizer or wiring are short circuited.
  • Weak Battery: The battery needs to be changed, or a higher rate battery is needed to be used. (If this happens, the DNA 40 will continue to fire the atomizer, but will not be able to provide the desired wattage) The Weak Battery message will continue to flash for a few seconds after the end of puff.
  • Temperature Protection: The heating coil reached the maximum allowed temperature during the puff. If this happens, the DNA 40 will continue to fire, but will not be able to provide the desired wattage.
  • Ohms Too High: The resistance of the atomizer coil is too high for the current wattage setting. If this happens, the DNA 40 will continue to fire, but will not be able to provide the desired wattage. The Ohms Too High message will continue to flash for a few seconds after the end of puff.
  • Ohms Too Low: The resistance of the atomizer coil is too low for the current wattage setting. If this happens, the DNA 40 will continue to fire, but will not be able to provide the desired wattage. The Ohms Too Low will continue to flash for a few seconds after the end of a puff.
  • Too hot: The DNA 40 has on-board temperature sensing. It will shut down and display this message if the internal board temperature becomes excessive.
  • Auto Power Down: The screen will be at full brightness while firing. After 10 seconds with no button pressed, the screen will dim. 30 seconds after the last button press, the screen will fade out and the device will go into sleep mode. To wake the device, press the fire button.
