One thing that I did find somewhat awkward using the Air is it's ..Human interface language ...
Based on colored light ...
Both the SMD LEDs used inside the Air are of the RGB type..
They can output red or green or blue light or their combined color*...
*Red+Green=Amber
Red+Blue=Violet
Blue+Green=Cyan
Red+Green+Blue= Varying shades of "white" (from blueish ,to greenish ,to pinkish )
So ,the Air is indicating quite a few things ,
by utilising these two RGB LEDs ...
Most of these colored light signals are already known ..
But are few that are not listed or mentioned at the manual ...
Some are just "operational combos" ,
for example when the unit preheats whille the wall adaptor is plugged .
At start,the lower "state" LED blinks "CYAN " ( GREEN from charging + BLUE from pre-heating ).
When the selected temperature is reached ,then the state LED alternates between CYAN (heating +Charging) and BLUE (heating ,not charging ).Thus the wall battery charger -most probably- is not used
for heating at all ( ..with a mere 1.2 A output ? No way !!! ) .
Others are more weird ...
Did some of you Air users got a top ("temperature set " ) LED blinking AMBER ,
while the unit was plugged in for charging immediately after a vaping session ?
If the answer is "yes" then do not worry ...
That's the unit's "battery thermal protection " kickin' in ...
It won't allow a warm unit to charge it's battery.
And is not self-resetting .
You will 've to reset the protection manually ,
by unplugging from the wall charger,
wait few minutes for the unit to cool down and then plug in again .
.....That and the low capacity of the bowls-stems ...
Just 0.95 ml of volume for the one with the plastic mouthpiece
and 1 ml of volume for the "all glass" one ...
That's about 250mg of ground herb ...
It could have been ,say 50% larger ...
1,5 ml or ~375 mg of herb ...
But ,hey ...
Maybe I'm asking for too much ,from an already GREAT vape ...
..............................
As also ,there are few other aspects of the unit that remain to be explored ...
For example the varying ratios of conduction/convection vaporizing that can be achieved with the Air ,by simple pushing in or pulling out the stem into/from the stainless steel heating chamber ...
(
From personal experience on the subject :
stem all way in = More of conduction vaporising .
Better suited with finely ground &tightly packed herb and low temps.
Stem out until "glass screen" is at same level with the top plasti cover of the unit =
More of convection vaporising (more room for hot air ) .
Better suited with medium to coarse grounded & loosely packed herb and higher temps .
Must allow for at least 20" between inhalations,for the fresh - and trapped inside the chamber - air to heat up .)
