The Basics About This Device

Just by the look of it Kamry’s KeCig 4.0 is a bit different than most Heat-Not-Burn devices. It’s small in size at 18mm x 57 mm x 42mm and one of the most lightweight items on the market at only 39 grams; it’s one of the few square products on the market; and it’s wrapped in a soft exterior coating that is easy to grip. It’s obvious that Kamry wanted to develop a product that stood out in a market crowded with knock-offs that mimic popular HnB device designs.

Despite the KeCig 4.0’s original physical design, it’s functions are common amongst HnB devices. It is an integrated device, meaning that there is only one element which contains both the battery and the heating chamber; it can be used consecutively 8-10 times; and it has a blade located within the heating chamber to heat the HeatSticks. Because functions are similar to those of other HnB devices, the KeCig 4.0 is easy to operate.

KeCig 4.0 does have some unique features, such as the ability to choose what temperature you want to heat at by switching the temperature control between ‘Low,’ ‘Medium,’ and ‘High.’ The device heats up to 243° C.

The KeCig 4.0 is offered in the colors; black, blue, or gold.

Kamry KeCig 4.0 is one of the best priced devices on the market as it sells for anywhere between $25.00USD and $30.00USD.

Product Unboxing and First Use

The Kamry KeCig 4.0 will arrive in a sleek white box that contains the device, a product manual, a warranty, cotton swabs for cleaning, and a Micro USB charging cord. Unfortunately, the kit does not include a USB wall adaptor.

Once you’ve unboxed your device, the first thing you want to do is check it’s charge. To do so, click the power button once and check the LED indicator lights. The more lights are lit, the more charge the device has. If no lights light up, then you have to first charge the device before using. One drawback to this device is the charging time. Officially it takes between 2 to 3 hours for the device to charge fully, however, our team found that it only took approximately 1 hour and 35 minutes to charge it. Don’t worry though as we, and most other users, found that the device was already charged upon arrival.

When you’re ready to use the device, gently insert a compatible HeatStick into the heating chamber and choose your temperature setting (Low – ‘L,’ Medium -‘M,’ or High – ‘H’). We recommend using ‘High.’ To turn on the device simply click and hold that same power button until the device vibrates once to indicate that it is heating. Once its heated to the desired temperature, it will vibrate again, letting you know that it is ready to use.

Kamry states that the device offers between 8 and 10 consecutive cycles, however we found that, on average, our test users got 11. After that the device needs to be charged again.

One cycle with KeCig 4.0 lasts approximately 3 to 4 minutes. When the cycle has ended, the device will vibrate one final time to notify you. KeCig is a multi-use device which means that if you do need another cycle, you can press and hold the power button once the device has fully powered off from the first cycle, and restart to the heating process. If you’re done after one cycle, slide the HeatStick out of the heating chamber with the HeatStick Eject Button, then push the removable cap back down, unless you are planning on cleaning also.

Testing – Day To Day Use

This little device packs a big punch! Despite it’s size, KeCig 4.0 offers one of the best throat hits out there. Our test users all agreed that it was incredibly satisfying due to the degree of heat that the device is capable of reaching.

Moreover, everyone loved the various features KeCig 4.0 is equipped with, such as the temperature adjustment, compact size, and self-cleaning button.

As we stated above, the Kamry brand promotes the KeCig 4.0 as being able to heat 8-10 HeatSticks consecutively. Some users found this works while others have not. Some users have even reported their devices only working for 6 or 7 consecutive cycles. Our test users found that they usually got around 11 HeatSticks. For optimal performance we recommend using the self-cleaning function daily or every other day. We found that this slightly improved the number of cycles we get out of the device. This sounds tedious, but remember all you have to do is press a button! See below for demonstration.

Once a week or so, fully remove the removable cap and clean it with the cleaning sticks.

First Time Switching to Kamry

This was our first time using a Kamry device and we were not disappointed. On AliExpress more than 200 people have reviewed the KeCig 4.0 and given it an impressive rating of over 4 stars. We now see why. Kamry KeCig 4.0 is a solid device. We would confidently recommend KeCig 4.0 to;

  1. individuals who want a secondary/ backup device
  2. anyone who has limited pocket/purse/backpack space when going out or going to work/school
  3. cost conscious users who are looking for a primary device

Investing in Kamry

The device is made by Shenzhen Kamry Technology Co. Ltd., a company founded in 2007, at that time under the name Fly Smoker Technology (HK) Co. Ltd. The company specializes not only in Heat-Not-Burn, but also electronic cigarettes.

While Kamry KeCig 4.0 is a solid device in terms of quality, there are other HnB devices on the market that outperform it. Nevertheless, if does not deserve to be written off. For it’s price, Kamry KeCig 4.0 a good value device. It’s sturdy, works well, and, most importantly, is satisfying.

Kamry HeatSticks Overview

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

Kamry KeCig 4.0 Manual


One thing we love about the KeCig 4.0 is that even though it isn’t produced by big tobacco, the device still comes with a warranty! This indicates that the Kamry team really wants their customers to have the best possible experience with their devices. Moreover, the 7-day money back guarantee shows that Kamry is confident in their product. That makes us feel confident too!

In your kit you will find a warranty card which explains a 7-day money back guarantee from the date you received the device and a 3 month replacement for the kit, battery, and/or mod.

To take advantage of the 7-day money back guarantee you must return the device in its original packaging to the manufacturer. The warranty does not answer whether the seller will incur the cost of return shipping or whether that’s left to the customer. There was no return postage included in our Kamry parcel or kit, so we here at Heat180 would bet that the cost of return shipping is probably not covered.

For the 3 month replacement warranty, you can keep the device so long as you send the: 1. Order Number, 2. Product Description (e.g. name and model), and 3. photo or video evidence of the damage or technical difficulty.
