Redefines "basic" & has some idiosycrasies. Not a strong recommendation, but does work and has several good points.
Both single and dual-cell versions of the Rigel are available. This review concerns the single-cell Rigel (Mini) which is only available in kit form, so includes a non-rebuildable "TFV-9 Mini" tank & a few nick-nacks. This isn't a tank I'd use myself nor recommend, so for me limits purchasing incentive.
But is the kit worth buying just for the mod? In my opinion, not really - unless you can buy at a knockdown price and tolerate the mod's inherent imperfections. For me the Rigel Mini's best point its unusually light weight, plus the non-metal external case which will feel much more comfortable to the touch in winter ambient temperatures.
The single 18650 Li-ion cell is accessed via magnetically-retained side panel similar to the Thelema Solo. Mine's rattle free & works surprisingly well.
The user interface features only a single mode (Power) which can be set from 1W->80W. There's no VPC, temp control, display brightness control, nor any others described in the Mod Box guide. So while it's totally devoid of gimmicky bloatware, if you're an experimenter then this mod is unlikely to suit you.
Unfortuntately, the Rigel Mini is affected by a similar (but slightly different) Power-related firmware problem that afflicts the Thelema Solo, Geekvape Z50, and likely others. This means that Wattage accuracy can deteriorate when using coils which have a non-zero TCR (e.g. SS316L).
For more details on the Z50/Thelema Solo issue, see Mod Box Guide, & scroll down to Wattage Calculated For Cold Coil Resistance.
The Rigel Mini kit minus the manual and other paper bits. A pretty little TFV-9 tank is included - but for me its's useless.
Pros/Cons
☹️ Doesn't work optimally with SS316L coils (As mentioned above). The simple work-around is stick to Ni80 or Kanthal A1, although this limits the mod's suitability for emesh, which generally makes use of SS316L. For anyone interested, a detailed description of how this issue specifically affects the Smok Rigel is included at the end of this page
☹️ Very limited Functionality No problem for me, but don't buy this mod if you wish to play with VPC, Boost, temp control, bypass mode, display colours,etc.
☹️ Wattage Lock Function Is Easy To Activate Inadvertently Simultaneously pressing the small up/down buttons locks the Wattage adjustment, although the mod can still fire. I've accidentally activated this several times. Worthy of mention but IMO not a serious issue
🙂 Single Watt Increment Has a 1W short-click Wattage step throughout its range, which for me is ideal
🙂 1W Minimum setting Can be set as low as 1W (many mods have a lowest of 5W) which can be useful for driving carts in some situations
🙂 Lightweight Plastic Case The Rigel Mini weight just ~63g (according to my scales) without battery & tank, only a third of the 182g metal-framed Grus 100). It also has a pleasant rubbery feel to it, which again I do like a lot. It'll be much less cold to the touch in winter ambient temperatures when metal-bodied mods can feel like ice.
🙄 Eight Second Fire Cycle Timeout Unlike many mods which have a 10 second fire cycle limit, the Rigel cuts out after 8 secs
👀 Reports of problems on the non-mini dual 18650 version of the Rigel I have no idea of how genuine/common these problems are, or even if they affect the Mini version. Issues seem to centre around USB charge port fragility, soldering of wires between battery case & circuit board, and also firmware errors resulting from overflow puff counter values.
Magnets top and bottom retain the battery door
No visible screws in the 510 connector - doesn't do much for my confidence in its security
The dual cell version of the Rigel, settable to 230W, but only powered by 2x18650s? Hmmm!
Basically, on this mod, the firmware only measures coil resistance when either ...
- the display activates following an idle timeout)
- the Fire button pressed for the first time after attachment of an atomiser
but at no other time (i.e. not continuously during a fire cycle, or even at the start of every fire cycle. Therefore it calculates and applies Voltage to the coil based upon the most recent of the above two events. For Ni80 and Ka1 coils, this is acceptable because their resistances don't increase significantly with increasing temperatures,
However for SS316L coils, this means that ...
The Wattage applied to the coil is calculated on either a cold coil resistance, or a partially warm (i.e. after reactivation after a timeout, which occurs after 15 seconds of no-button presses)
If using wires with non-zero TCR, there will be a Wattage shortfall approximating or closely following the "Single Cold Coil Resistance Measurement" graph as shown on the mod guide page

Arguably a pretty tank, but mine is dustbin-fodder
Power mode display, the only option on this mod
