    1 comment / Posted on by Karter Au-Yeung

       In May 2017, iJoy will bring the first vape 20700 battery and box mod to the market. 18650 batteries have been dominating the vape game as the number one e-cig battery since the dawn of the industry in early 2007. At the same time, Tesla Motors have also switched to engineering their car batteries out of 20700 batteries now instead of 18650 batteries. This marks a major turning point in lithium cell standard and is a testament to the prowess of the 20700 battery.


    iJoy 20700 Battery Specs:

    - Size: 20700

    - Type: Li-Ni

    - Typical Capacity: 3030mAh

    - Minimal Capacity: 3000mAh

    - Nominal Voltage: 3.7V

    - Peak Voltage: 4.2V

    - Cut-off Voltage: 2.5V

    - Dimensions: 20.4mm (Diameter) x 70.1mm (Length)

    - Rechargeable: Yes

    - Max Continuous Discharging Current: 40A

    - Max Pulse Discharging Current: 85A

    - Style: Flat Top

    - Color: Black and Gold

    - Rated Capacity: 3000mAh


       The real limitation is the number of devices uses 20700 batteries. The success of the 20700 is dependent on the adaptation of 20700 devices. The relationship between the battery and device is not only mutually dependent but also symbiotic in this early stage of cell standard revolution.

  • The Calculations of Sub-Ohm Vaping

    Ohm Calculation for Vaping

    Sub-Ohm vaping is the art of vaping using a device with an atomizer resistance of below 1 Ohm. This kind of vaping can be a bit complicated and therefore, it’s not for everyone to try. However, if you’re adventurous and like extremities, then Sub-Ohm vaping might be for you. But, first you need to understand the law and calculation of this kind of vaping for you to be in a capacity to handle it.

    Sub-Ohm Law

    • I =V/R
    • Electric Current = Voltage/ Resistance
    • Electric current refers to the total charge flowing through something. It’s calculated in amps per seconds.
    • Voltage in this situation is used to refer to voltage difference. This is the difference in electrical energy potential between any two points.
    • Resistance in this case means the level of obstruction for electrons in a given circuit. It’s calculated in Ohms.
    • Using this Law, it’s true to say that voltage is reduced by the resistance to produce the electric current.
    • Sub-Ohm vapers use this law to predetermine the power output of their devices. In this case, if you decrease the resistance of your atomizer (Ohms), the power output of your device will increase. This means more vapor will be generated.
    • This law is especially applied to mechanical mods with a fixed voltage. If you want to increase the quality of your vapor, the only alternative you have is to decrease the resistance of your atomizer, thereby increasing the output power.

    When applying this law of vaping, it’s important to note that more amperage is required as resistance is reduced. This means that your batteries or coils will be generating more heat. Therefore, always ensure that your batteries never exceed their amperage limit as this could lead to an explosion or fire.

  • The Differences between Digichargers and a Smart Chargers

    0 comments / Posted on by Daxin Chen

    ‘Digicharger’ and ‘smart charger’ are terms that’re used interchangeably, so you need to know what you’re getting into when you’re looking for the right kind of charger. The charger you choose should give you a digital display or give you information about how your device is charging.

    The Display

    A digicharger has a digital display that’ll show you how the battery’s performing. You can see the temperature of the battery, how fast it’s charging and how long until the battery’s charged. You can use this information to charge everything more efficiently, and you can use this information when you’re trying to charge your device fast when you have little time. You need to have this information so that you can get the best charge possible. A slow charge is no good for you, and you can try plugging into a different outlet, and you can find a different outlet when the battery’s overheating.

    Smart Chargers

    Smart chargers use the same kind of technology, but a smart charger can make changes for you without your input. The smart charger will change the rate of the charge on its own, and it’ll begin to make changes if your device’s overheating. This is the best way to charge your device when you don’t have time to watch over it.

    Which Charger’s the Best?

    You need to pick out a charger that is going to work best for you, and you need to make sure that you are going to get a charger that you can look after. Avoid a digicharger when you’re not going to have time to look after the display, or you can get a digicharger when you can watch the display.

    Get a smart charger when you need the charger to do some of the work for you, and you will be able to get your device charged in a matter of moments. This is going to change the way that you use your device, and you will be able to get better results because the charger is easy for you to use every day.

    The vaping world knows that the battery is the most important part of the MOD. The introduction of MODs in the vaping world brought with it additional power requirements. Sorry to quote the well-known cliché ‘with great power comes great responsibility’ for this purpose but if the shoe fits. MODs are designed to give out more vapor faster so that you can get the throat hit desired. But this advancement requires more power to work effectively and hence the battery is considered the most important part.

    It goes without saying that care is needed when handling all forms of batteries. Using the wrong battery could literally end up blowing up in your face. Imagine hooking up your flashlight to your wall socket, you will just end up picking up glass particles all over the floor. Picking a wrong battery for your MOD could end up in almost the same way, only now you might be nursing a scar on your face as well. Selecting the right battery guarantees you safe usage of your MOD for all your vaping needs, for the lifetime of the battery and it ensures proper functioning of the mode. Using the wrong battery could either result in over vaporization or under vaporization.

    You also don’t need to be a physicist to know that if you skimp on your power source your MOD may not work as needed. Ohms law should guide you in the selection of your battery. MODs come with a guide of the recommended amp of the battery. Should you skimp out and use a battery of a lower level ampere you might push the battery beyond its limits and the result is either the battery will start leaking dangerous chemicals and don’t forget the battery might just go ‘boom’ all over your face. 

    The safe bet for you is to select either one of two batteries, a protected ICR or an IMR chemistry batteries. The ICR last longer attributable to its increased storage capacity while the IMR is useful in lower resistance coils Depending on the MOD specifications we have the battery that guarantees safety and battery life worth the money you lay out. For instance there’s the rechargeable ICR 18650 from Aspire with an amp backing of 40A and high discharge useful for MODs that drain you fast. There’s also the CF MAXX variable wattage battery; compatible with coils ranging from 0.3 Ohms to 5.0 Ohms also don’t forget the overheat protection inside the cell as an extra safety measure. Lastly there is the rechargeable IMR 18650 from IMREN; it has a 2500 mAh storage capacity and delivers a 40A current useful for power draining MODs.

    Vapers out there love to show off their passion for vaping. It isn't like smoking regular tobacco; it’s about savoring the different flavors. The way you inhale or exhale the thick vapor effects your experience while vaping. That’s why vapers have invented different vaping tricks for fun.

    Become the life of the party by entertaining others with these cool vaping tricks:


    A Vapor bubble is one of the funniest tricks. You’ll need a few supplies; Take an empty toilet paper roll, soapy water, and your electronic cigarette of course.
    Once you have these things, here are the 3 steps to pulling off this trick:

    • Dip the end of the toilet paper roll in soapy water.
    • Take a long, hard pull from you device and blow vapor into the toilet paper roll.
    • The vapor will cause a bubble to form. 


    The cloud dragon technique is a little more challenging. Take a very long pull from your device without inhaling any smoke. When you’ve a mouthful of vapor, exhale through your nostrils using a little bit of force while also exhaling some vapor through the corners of your mouth. This will create a cool effect that emulates a dragon breathing out fire.


    One of the most common yet popular vaping tricks is cheerios. The trick takes a bit of practice but once you get the hang of it, then it’s fairly simple to do. Here are the following steps for this trick:

    • First, take a long pull from your vaporizer or MOD and hold the vapor in your mouth
    • Next, form an O shape with your mouth and push you lips out.
    • Then slowly blow out vapor and small o's will start to form. 

    Make sure to leave your tongue flat at the bottom of your mouth; otherwise the trick will not work.


    Last but not least the tornado trick. This is one of the hardest tricks to learn and will take the most practice. Like the vape bubble trick, you’ll need a toilet paper roll. You’ll also need a flat tornado surface for which you’ll be blowing the vapor on to. A piece of paper on the ground will do the job. 

    • Take a long pull from your device and exhale the vapor through the toilet paper roll onto the tornado surface. 
    • Form a karate chop motion using your hand through the vapor lingering on the surface; then flick your wrist. This will cause the vapor to swirl upward forming a small tornado for a few seconds. 

    Try to do it all in one swift motion. 

    Once you learn these awesome tricks, all of your friends will be asking you to show them how to do it themselves. This can be a great way to share your hobby and show-off your mad skills at the same time.
