The Kangetech Nebox is an all in one device. It takes a single 18650 Battery, has a 10ml tank, and can use Nickle, Titanium and Kanthal coils. The coils can be disposable or you can use the supplied mini RBA. It has Temperature Control or adjustable wattage modes. It can save up to 6 pre sets for differing vaping preferences. For a newbie or someone seeking convenience the internal tank is great. No separate tanks to mess with. The internal tank performs well and has a large 10ml capacity. I see this as a big advantage in cost and ease of use, others may miss playing with their tanks. It is a discreet device being small enough to fit in the hand with only the drip tip showing. The clouds are gonna give you away though! The build quality is surprisingly good for the low price point ($51.00 on FasTech) but it could be better. The buttons feel insubstantial and the thread on the battery cover had paint in it. It is a solid unit and everything functions but SS buttons and better machining on the threads would make a big improvement. It is heavier than I thought it would be and with battery and a full tank it feels substantial in the hand. 10 ml capacity is awesome. The hassle of dragging juice and fiddling about refilling in the field is no longer necessary. Fillup in the morning and I am right till might time. For a beginner (like me) the mini RBA is a great addition. I can play with this technology without the expense of a separate tank etc. TBH I prefer the Ni200 coil but I can experiment with build and coils whenever I wish. The Temperature Control (TC) in the Nebox works very well for me. I tried a blast at maximum settings (300c and 60 watts) just to see what it was like. The flavour was good and the vapour was big but I found it a bit warm for my liking. I’m pretty sure battery life would be a problem if you used this setting all the time as well. I find it best set to 265c @40watts. TC is very easy to use. You set it how you like and every time you vape it is exactly as you like it. TC is like the auto function in a car. Sure a manual can be more fun but auto is heaps easier when you just want to get to work, pick up the kids, pop to the shops etc. In TC mode the wattage only has the effect of controlling how quickly the coil comes to temperature. I found that below 35 I can detect the delay and that at 40 and above I cannot detect a delay. The delay can be measured in nano seconds so it can be operated at much lower wattages with no ill effect on the vaping experience, it’s just how I like it. Using the 0.15 Ohm NI 200 coil that comes pre installed is a pleasure. Clean, crisp flavour and big fluffy clouds with a 60/40 vg/pg mix. The coil seems to be lasting very well. I have put more than 80mls through and it is still going great. I don’t think you would win a cloud throwing contest with this device but it is more than satisfactory for the home enthusiast. Airflow is not adjustable but is strangely good as it is. I immediately liked the draw as it is and would not seek to adjust it even if I could. You could use an airflow controlled drip tip or stick your finger over the inflow to restrict if you desired. This seems to be a straight hit device only. I can’t see a way that it could be used for mouth to lung effectively. This may be a limitation for some but it is not for me as mouth to lung causes me to cough so I don’t do it. This device would be an excellent choice for someone who is seeking to step up from ego type devices or who want to safely try sub-ohming. It may be a good choice for a beginner but they need to have decided whether they are a lunger (like me) or a mouth to lunger. UPDATE The air intake requires regular cleaning. The black crud that forms on the coil can fall into the air intake. The crud may make you think the coil is done for and may cause seepage. It requires a thorough cleanout with warm water and cotton buds.
