The Best Mini Model – KR808 vs 510

Today there are dozens of electronic or vapor cigarette models to choose from, but mini size devices that mimic tobacco cigarettes are by far the most popular between mainstream vapers and manufacturers. Up until a few years ago the 510 model reigned supreme in the mini e-cigarette category, but these days KR808 is gaining more popularity.


Which is the best ‘mini’ model?

The truth is both models have pros and cons therefore it comes down to what a vaper appreciates most about an electronic cigarette. Do they want a flexible device that works with most of the available battery styles and vaping accessories, or are they looking for long battery life and great overall performance? It might seem like the only thing separating these two models is the threading, but they are much more different than most people assume.

The 510 Model

The 510 electronic cigarette has been around for a long time and it’s still a favorite with both developers and most members of the vaping community. Virtually everything that gets invented in the world of e-cigarettes starts out with a 510 connection, and eventually drips down to the KR808. Although an adapter can be used to make 510 accessories compatible with KR808 batteries it’s much more of a hassle, plus it sometimes makes the device look awkward. The vast majority of mods are built with a 510 connection, including the popular eGo. Bottom line – the 510 electronic cigarette is much more versatile; it can be used with atomizers and e-liquid cartridges, cartomizers, drip tips, clearomizers or tanks. The possibilities are endless and this is probably the main reason so many hard-core vapers prefer the 510. It gives them the opportunity to experiment with different equipment and find out what they like most.

The KR808 Model

The KR808 was designed to be used exclusively with a cartomizer. There are no commercially available atomizers and cartridges for the KR808. So as far as versatility goes, the 510 is clearly the superior device, but if one prefers a two piece device, there’s no beating the KR808. Popular brands offer re-usable cartomizers that don’t burn, even when the e-liquid gets depleted.

The Battery Life

Another aspect one needs to keep in mind when choosing an electronic cigarette, is the battery life. Just because these two models are about the same size doesn’t mean they last just as long. In the beginning, the average 510 had a mAh rating much inferior to the newer KR808. It was regulated at around 3.2 volts and held a charge of 180 mAh. That meant you would get about 100 puffs before you had to recharge it. The superior 808 was a true 3.7-volt battery, with a mAh capacity of 280 (the latest 78 mm devices have an improved rating of 320 mAh). Depending on one’s vaping style, one would get over 200 puffs on a single charge. But things are changing rapidly in the vaping world, and one can find 510 mini e-cigarettes with ratings that go all the way up to 350 mAh. So while the KR808 used to have a noticeably superior battery life, the two models are pretty evenly matched, at the moment. Having said that, KR808 fans can also enjoy larger batteries that go all the way up to 1,300 mAh, thanks to the rapidly-evolving technology.

Quality of Vaping

There aren’t any statistics that could be quoted to separate the two models in the quality of vaping department, but according to some experts the KR808 has the edge. It has a newer, more responsive switch, the draw is noticeably easier, probably due to the fact that the air holes are placed in a better location that on the 510. Vapor production also seems to be a little better on the KR808, but only when the battery is used in conjunction with those new-generation cartomizers and clearomizers as mentioned above.

The Bottom Line

The 510′s versatility can’t be challenged at the moment, but the popularity of cartomizers makes KR808′s simple two-piece design a popular choice with beginners and vapers looking for an alternative to cigarettes that doesn’t require getting their hands dirty.
