The Basics About This Device

JOUZ is one of the newer Heat-Not-Burn manufacturers. The company is turning a mere 1 year old on the 20th of June, 2019, nevertheless since their debut last year JOUZ has impressed industry insiders. JOUZ currently has 4 devices available to purchase: JOUZ 12, JOUZ 20, JOUZ 20 Pro, and JOUZ S. In this review we will be looking at the JOUZ 20.

JOUZ 20 is an integrated device that can be used approximately 20 times consecutively and has a lifespan of approximately 1-2 years. It weighs only 56 grams, but works well and delivers a satisfying experience, due to its unique, internal air channel design. The device’s outer design is equally impressive as JOUZ 20 is sleek and modern while still sturdy and functional. JOUZ 20 is easy to use, as all of the device’s functions are controlled by the start button.

We’ve enjoyed the JOUZ experience and feel that this company has real potential for growth within the HnB community!

Difference Between JOUZ 20 and JOUZ 20 Pro

JOUZ 20 Pro is an updated version of JOUZ 20. JOUZ 20 Pro offers temperature adjustment, Bluetooth connectivity, and has a premium leather exterior. Other than these differences, both devices share the same functions.

Product Unboxing and First Use

When you purchase JOUZ 20 it will arrive in a kit which includes: the device, 2 dust covers, a cleaning device equipped with a hook, 4 cleaning sticks, a Mirco-B USB cable, a manual, and a card detailing how to clean your device. The packaging for JOUZ is quite unique. We tend to find that most HnB manufacturers design their packaging to be similar to what if offered by bigger, brand name companies’. This tends to be sleek and modern looking, opaque white boxes with a picture of the device on the outside. JOUZ has done something different, as, despite the color scheme still resembling IQOS’, the packing is something we have not seen before. It is a clear plastic, rounded box which allows you to look at the device held within. It’s eye catching and also gives you a good opportunity to evaluate the device design, if you are able to visit a JOUZ retail location.

When you first open your kit, it is recommended that you first check the device charge. To do so press and hold the start button and take note of how many LED indicator lights lit up. If one lights up then the device has a charge level of 0-35%. If two light up it’s 36-70%. If three light up 71-100% charge is remaining. The manufacturer recommends using his device only when fully charged and therefore, if all 3 LED indicator light do not turn on, you must first charge the device by pushing down on the USB charging port cover on the bottom of the device and attaching it to the USB cable. JOUZ 20 takes approximately 2 hours, 32 minutes to charge fully.

Once charged, you can begin to use your device. The first step is to insert a HeatStick into the HeatStick heating chamber. Be careful when doing so as JOUZ heating chambers contain heating blades and so should be handled gently. Once inserted, press and hold the start button until the device vibrates and one of the LED lights begins flashing. The device will take approximately 20 seconds to fully heat, at which time the device will vibrate again and all 3 LED lights will turn solid.

JOUZ 20 lasts approximately 5 minutes and 30 seconds, or 14 puffs. This is the main heating period. There is an added bonus to JOUZ, however as after this time has run out, heating will last for another 30 seconds or 2 puffs as indicated by a device vibration and the LED lights flashing white. After this added time the device will power off and you can remove the HeatStick.

If you want to enjoy another cycle, wait for the device to fully power off then press and hold the start button once again until the device vibrates. Officially, JOUZ allows for 20 consecutive cycles, but we found that we got 22 before needing to be charged.

If you ever need to turn off the device in the middle of the cycle, just press and hold until the device vibrates and the LED indicator lights turn off.

Much like the last device we reviewed, AYI TT7, to remove a HeatStick, slide the cap up and then gently pull the HeatStick out. If you do not push the cap up, larger amounts of fallout and other debris could be left within the heating chamber, which, if not cleaned, would then affect the health of your device. And of course, when removing the HeatStick from the heating chamber, try not to wiggle or rotate it.

Testing & Day to Day Use

Our tester users really liked this device. Most reported that they liked the high number of HeatSticks which could be smoked. They found it convenient and easy to use. The design was a big draw for people, most of whom noted that it was sleek and modern looking, lightweight, resistant to scratches and stains, and is discreet.

Our testers always ensure that they clean their HnB devices regularly so that the devices perform well. The JOUZ manual also recommends that. To clean JOUZ 20 first check to ensure that the device is powered off and has had enough time necessary to cool down. Then remove the cap. If using the cleaning device, carefully lower into the HeatStick heating chamber and rotate. When it appears that any remnants of tobacco has loosened, turn the device upside town and gently tap on the side until the debris falls out. You can also use the hook tool, which is attached to the cleaning device, to remove any debris from the cap itself. Insert it into the cap and twist. If using the cleaning sticks, very gently insert it into the HeatSticks heating chamber and wipe away any residue.

JOUZ 20 also has a built-in self-cleaning function for extra convenience. It is recommended that you use this after every 20 cigarettes. One of our test users said that he got into a habit of cleaning the device any time he had to charge it, since that was after approximately 20 cigarettes. To use this feature, press and hold the start button for 6 seconds. When it’s been activated, all 3 LED indicator lights will begin flashing at the same time. Cleaning will take about 30 seconds, at which time the device will automatically power off and the lights will turn off. Much like the cycle itself, you can stop the self-cleaning function by pressing and holding the start button.

Investing in a JOUZ Device

As we said above, JOUZ is one of the newer HnB manufacturers but that doesn’t hinder it’s status within the industry. Within the span of a year the brand has successfully launched 4 devices in Japan, South Korea, Russia, and China and now has plans to expand to the UK, US, Italy, Ukraine, and Colombia. It’s obvious JOUZ representatives are thinking global. We feel that this a great indicator of a potentially strong brand.

Moreover, JOUZ seems comfortable investing in promotion of and support for their products. The manufacturer is very responsive and appears to be in this for the long haul.

If you want high quality devices at an affordable price, JOUZ may be a brand you’d want to consider.
