The Basics About This Device

A few weeks ago we reviewed the X7 device. In that review we talked about how some HnB devices are not branded by the original manufacturer (OEM) so that they can be resold by other companies (VARs). Today we are reviewing another device like that.


Langqin is an integrated, multi-use device that offers an astounding 47 continuous cycles! Langqin offers both temperature adjustment and self-cleaning. It is a solid device that we thoroughly enjoyed testing. Although Langqin does have a brand name, the product itself is rarely ever marketed as a branded product. There is no name included either on the packaging or on the instruction material included in the kit, if requested. This makes Langqin a bit more difficult to find online for purchase.

If you make an effort to find it though it is definitely worthwhile. The high number of cycles alone is a bit draw for most of us here at Heat180.

Langqin is available in numerous colors and finishes, including blue, gold, and gray. However, if you purchase from the official retailer, you may be able to snag an exclusive color such as the one we have blue and black ombre.

Product Unboxing & First Use


In your Langqin kit you will find the device, the manual, a USB cable, and a cleaning brush.

When our device arrived it was fully charged but if yours is not, just plug it into a power source. The LED indicator light will flash as the device charges but will turn off once full charge has been reached. Charging will take approximately 1 hour and 57 minutes.

We’d like to note that this is a fantastic charging time for a device that gets 47 cycles! Most devices that are near the 40s take around 3 hours! We are blown away!


Once your device is charged, you can begin the heating process. To do so, press and hold the control button until the device vibrates and the LED indicator light begins flashing.This indicates that the device is heating. Heating will take approximately 10 seconds total. When fully heated, the device will vibrate again and the LED indicator light will turn solid.

Now this device is a bit different than most as temperature adjustment is done after the heating process has begun. So to change the temperature start the device by pressing and holding the control button, let go once you’ve felt the first vibration, then click the control button once more to change the temp. This should change the color of the LED indicator light. Blue indicates low heat, yellow is medium heat, and red is high heat. Now you can continue with your cycle.

The Langqin cycle lasts approximately 4 minutes, 3 seconds. Of you ever need to stop the cycle, just press and hold the control button until the device powers down. Since this is a multi-use device, you can begin another cycle directly after finishing one, if you want. If not, just lift the cap up and pull your HeatStick out.


Day to Day Use

Luckily, Langqin has a self-cleaning function, to make it easier for you. To use the self-clean, click the control button in rapid succession until the LED indicator light begins flashing blue, red, and yellow. Self-cleaning should take around 39 seconds total.

We recommend self-cleaning daily since it’s so easy, but you also need to manually clean the device. To do so, lift the cap off of the body of the device and gently insert the cleaning brush. Use the brush to sweep away any built up grime.


One more feature that is important to know about with Langqin is a locking feature. If you click the control button 5 times in rapid succession, the LED indicator light will flash yellow. This locks the device, thus ensuring that it would not accidentally start on you and drain your battery. Fantastic!

Investing in Langqin

Our team here at Heat180 loved testing Langqin! We like all the features Langqin comes equipped with, such as temperature adjustment, self-clean, and locking. And of course, we were amazed by the high number of uses you get out of this device!

Langqin, although not manufactured by a big tobacco companies, or ever a well-known smaller brands, is a good reminder that sometimes you can find great HnB products from unexpected sources! Langqin is by far one of the best devices out there, especially for the price!

HeatSticks Overview

The Langqin brand does not product their own HeatSticks. Instead, their devices are designed to work with other branded HeatSticks, such as HEETS and Marlboro for IQOS HeatSticks.

    You can’t get much better than this for number of uses. Hopefully the brand will become bigger in the industry because 47 cycles is a great amount.
