It’s a situation that we’ve all found ourselves in, you’re out and about happily vaping away on your 18650 powered mod and the dreaded low power message flashes up. That’s it, game over; everyone go home.
Maybe a tad dramatic but you get the point. Vaping, like most battery powered technology, has been held back to a degree by battery capacity, luckily for us – necessity is the mother of invention. With the recent surge of 20700 and 21700 batteries, vapers are being given access to a power source that matches their needs.
All of the 18650, 20700, and 21700 vape batteries get their name from their size dimensions. An 18650 battery has an 18mm diameter and a 65mm length, with a 20700 battery having 20mm diameter and 70mm, and the slightly larger 21700 battery being almost the same size as the 20700, but 21mm in diameter. On the face of it these dimensions are quite similar. The difference in performance however, is very noticeable.
There are a number of advantages to the 20700 and 21700 vape batteries. They generally have an increased mAh output compared to 18650 batteries as well as a longer lifespan, sometimes up to 13 months depending on how heavily they’re used. Perhaps most importantly, they can help increase the battery life of your favourite mod. Most mods that take a 21700 will also fit a 20700, so it seems these two batteries almost go hand in hand together.
With this in mind, we’re going to give you a rundown of some of the best 20700 and 21700 vape devices currently available on the market.
Eleaf iStick Pico 21700 Kit
A reimagining of the classic Eleaf design, the iStick Pico 21700 is an easy to use starter kit, that benefits from an increased battery life and a maximum output of 100w. Included with the kit is the Ello vape tank, which features a wide flow and uses low resistance atomisers. Overall this is the perfect mod for someone looking to get into sub ohm vaping, and who will benefit from using a 21700. If this seems a bit daunting, don’t panic, the kit is also compatible with an 18650 0r 20700 battery!
Wismec RX2 21700 Box
Well, Wismec have done it again, the latest in the incredibly popular series of RX vape mods, the RX2 21700 mod features the chunky design and smooth curves that made the original such a hit. The new version has 2A charging, which means you’ll be up and running faster than usual, when those dual 21700 batteries eventually do run flat. With the included battery adaptor, the RX2 can also support dual 18650s.
Geekvape Blade 235W Box
The Geekvape Blade 235W TC is a vape device that has much of the functionality usually confined to high end vape mods, including: variable power control – five programmable wattage presets the user can select, for the Blade to fire at sequentially and Bypass Mode – allowing the device to draw power directly from the battery, like a mechanical mod. This combined with a colourful design, makes for an eye-catching dual 21700 battery mod. The Blade also comes with a battery adaptor, meaning it can use dual 20700 batteries or 18650 batteries as an alternative.
Lost Vape Mirage DNA75C Box
The Mirage DNA75C Box is powered by a single 21700 battery and utilises the powerful Evolv DNA75 Chipset, allowing for consistent firing rate and balanced output features with a maximum output of 75W. Furthermore, it has a strong aesthetic, thanks to the resin inlay, providing each with a unique colour swirl pattern. What’s more, by fitting the battery adaptor the Mirage can be powered by an single 18650 or 20700 rather than a 21700 battery. If you’re looking for a mod that holds it charge and looks good while doing it, you’re in safe hands with the Mirage.
Ijoy Capo 100w Squonk Kit
Even squonk enthusiasts aren’t being left out in the 21700 battery movement. The Ijoy Capo 100w Squonk Box is powered by a single 21700 battery, with the option of using an 18650 or 20700 when used with the correct adaptor included. The Capo has a generously sized 9ml squonk bottle – fill that up and you’re good to go. The kit also includes the Ijoy Combo RDA, with it’s angled build deck that will fit a range of coils. Those looking to take the plunge into squonking with a big battery reserve need look no further than the Ijoy Capo 100w Squonk Kit.
As can be seen, both the 20700 and the 21700 battery are both becoming a staple power source for vapers, for both vape starter kits and high-performance box mods, giving vapers of all levels access to better-performing vape devices.
