Simplicity is key

The essential part of any AIO vape device or vape pen is simplicity. They are usually geared towards beginners who don’t require all the bells and whistles but just need something easy and portable to get them off of smoking.

The OBS KFB AIO Kit is exactly that, no fancy gimmicks or features, just a traditional AIO vape pen. It measures in at 21 mm in diameter, and 130 mm in height. Inside this compact design are a single 18650 battery and a 2 ml tank atomizer.

However, the OBS KFB AIO Kit does lean more towards the sub ohm style of vaping and has few features that may help it stand out from the crowd. Firstly it has a 50W maximum output, which is impressive given its compact size. Secondly, it uses pre-made BVC coils, which are rated for the 25-50W output range.

All this coinciding with the fact that OBS have had extremely great success with their atomizer designs means users can expect a good vaping experience with large clouds and decent flavor production.

Additional features include side-filling e-liquid ports, a small front-facing firing button, a 12 mm resin drip tip and adjustable top-airflow control.

There’s no doubting that OBS has made a stylish looking and compact AIO device, equipped with the essential basic functionality. Nonetheless, the OBS vape pen doesn’t bring any distinct new features to party, so it’s success will likely hinge on the performance of the atomizer. Although, we are certainly interested to find out just how well it performs.
