Innokin JEM Pen Package Content


Innokin JEM is a stunning refillable vape pen available in several color options. It is a slim vape pen with a 16mm diameter that easily fits in your fist. Besides, it has a stainless steel body and is lightweight. Carry it in your pocket or purse and have a good time with the vapors. It has a simplistic design that consists of a battery unit, a tank, a coil, and a drip tip. It is an affordable item costing less than $20 on different online platforms.

JEM features a stylish plastic fire switch. The windows on each side of the tank allow you to see how much e-juice you have left. In case you need to refill, there are two side openings on top of the tank. Twist the top and replenish the reservoir. There is also a tiny air hole above the firing button, but the airflow is not adjustable, thus restricts the kind of puffs you get.

The stainless steel construction around the glass tank protects it against damage, for example, when you drop your vape pen. There is no spare tank, so you have to be a little more careful with the product. Enjoy the 2ml capacity, which is a TPD compliant, thus perfect for users in European countries as well.

You do not need multiple buttons to use this pen. It only has one button for firing, which serves other functions as well, such as turning the device on and off. There are no modes or settings to select. Pick up Innokin JEM, install the coil, fill the tank, use the fire button to turn it on, and start vaping.


Innokin JEM Pen comes with two types of coils a kanthal wire with 1.6ohms resistance and a ceramic coil with a rating of 2.0ohms. However, the resistance range for the pen is 0.6-3.5ohms. Note that the pen does not come with a coil pre-installed. You have to screw it in place through, fill the tank, and give the gadget five minutes before you start inhaling nicotine fumes.

With the Kanthal, it can work with e-liquids of 70VG/30PG while the ceramic option performs well with 60VG/40VG e-juices. However, both function correctly with a 50PG/50VG e-liquid and provide delicious flavor and thrilling vapor.

The product provides a constant output for smooth vaping and flavorful clouds. It is a mouth to lung (MTL) vape pen, which makes it perfect for cigarette smokers shifting to vaping. The throat hits are great for beginners to ease the transition from smoking to vaping.

Innokin JEM Pen Coil


Innokin JEM is a powerful brand that runs on an internal 1000mAh battery. Such a capacity is much more than what some pens are offering. Charge the cell through the USB port using the provided cable. When charged fully, JEM can last a day before requiring a recharge. However, how fast you deplete the battery power depends on your vaping habits. If you are a chain vaper, a full cell can last for six hours.

Remember, you cannot vape while charging this product. Unfortunately, it takes over an hour to recharge; you have to be patient. Besides, it does not use removable batteries, which is an inconvenience when on the go and without a power source.

On the upside, Innokin JEM Pen has a tricolor LED battery indicator. You do not have to worry about the cell depleting without you knowing. When it lights up green, it means the cell power is 60-100%, yellow means it is 20-60%, while red shows that the battery is 0-20% full. When the pen is fully charged, the LED light does not go off.

Innokin JEM Pen Battery


A great vape device has safety features incorporated in its design. Innokin fosters your security through including several protections in its JEM pens. It safeguards the devices against overcharging, over-discharging, overheating, short circuits, and high resistance.

It also features a 15-second cutoff. These measures exist to ensure the durability of your vape pen and to keep you safe while vaping. You can vape using an overheated pen, for example.
