Wotofo Flux Kit review by KingPin!

[KingPin!]

Hi Folks,

So here’s one for you...what does “Vaping American Made Products” (VapeAMP) creators of the high end Rig Mods mechanical mod series and Wotofo have in common?…Other than the obvious of making money; VapeAmp had already expanded into China with their “worldwide” badge in collaboration with HotCig for the RSQ Squonker, in my mind it should come as no surprise they will be looking to continue partnerships with other companies in Shenzhen; both to remain competitive in the vape game and increase brand presence in the mid range market.

So to answer the above; for me it makes sense, after all Wotofo is an established brand as is Rig Mods and together they could certainly come up with a decent product.

Let’s find out if they succeeded; in honorary tradition I was sent this kit directly from Wotofo for the once over. As usual with any of my kit reviews I’ll go over the tank first, then the mod. I don’t like to make recommendations in my reviews; I’ll go over my findings to help bolster your research should you be interested in the product.

So without further ado…

Build Quality and Impressions

I know this is the tank part of the review but I’m going to start with the packaging. Yeah the graphics are great, eye catching, fresh and trendy… but the box is unwieldy and from an ethical stand point I don’t get why so much plastic is needed to house this mod and tank, it’s like an ice cream tub! It must cost Wotofo a fortune shipping this around the globe filling up shipping containers with a mere 10 or so packages, ok that’s a slight exaggeration, but still I personally don’t like seeing waste on this scale. I hope to see this trend discontinued in future products; perhaps go smaller and use sustainable materials Wotofo.



Ok the flux kit has some pedigree behind and that shows in the price tag, but Wotofo is marketing this as a starter kit. With this in mind I fully expect to see extra options for users. For instance a 510 adaptor and 510 drip tip so people new to vaping can try different styles, plenty of O-rings because things will get lost or destroyed and a spare glass with a band for the bubble glass at the least. You get half of this list included which is disappointing. Don’t like the drip tip...sorry that’s hard luck, lose or destroy an O-ring...you’ll get one spare so don’t lose it, spare bubble glass you say…there’s no protection band so don’t break it.



The Flow Pro’s finish is what looks like a powder coat and it matches the mod well, but there are parts I’m unsatisfied with; bubbling on the base of the tank (I suspect this paint will come off at some point)



Underneath the base was what I can only describe as a mess.



And finally the O-ring at the bottom of the glass was stuck fast to the glass itself. I nearly had to break the glass to remove it during its initial cleaning because there is a distinct lip around the base holding everything in place. I had to ease the glass off; pushing it to one side gently so it popped away from the lip, after that I tried to gently remove the O-Ring from the glass. Sadly I failed so that’s my single spare used up already.




Not a good start there Wotofo I wonder if this particular unit should have passed quality control at all?….With these bits out of the way it’s pretty plain sailing because the tank is using a very similar template to some of the other starter tanks capable of using SMOK baby beast coils.

You have an 810 size shorty drip tip with a fairly narrow tapered bore leaving it closer to a 510 which I like. Despite the lack of height it’s comfortable to use as the tank doesn’t get too hot with the coils provided, unless you seriously chain vape at the higher end of the wattage range. If you happen to dislike the tip you’ll be able to swap it out easily enough for an aftermarket option as it’s a standard industry size, just make sure whatever you choose has a shallow base or it won’t sit flush (the Recurve RDA tip fits fine). I found the O-ring holding the tip in place was a little on the lose side which is a shame.



There is ample knurling around the airflow control ring and top cap which is good.

I would like to have seen a marker on the top cap as to where I’m supposed to push it back to reveal the refill port because I end up feeling around trying to find it every time. The strangest bit is they used a sticker only on the straight glass showing you where you need to engage it? I peeled this off out of the box and almost missed it, another poor effort in my opinion.

I also found the top cap a little stiff to engage so beware those out there with painful joints or weakness in their fingers, it does ease up over time a little though.

Once you manage to shift the top cap back you’ll find a single 10.7mm x 3.5mm juice port. It can be a little tricky to refill this tank with the wider twist top nozzles; PET dropper bottles work really well though. As with all push back top caps any juice overspill or condensation sitting on top; will get squeezed out when fastening on occasion.



The tank utilises the now standard “Smok baby beast size coils” which opens the tank up to a large range of aftermarket purchase options which is always great for the beginner out there. The chimney section screws on top of the coil but is slightly recessed leaving it with a narrower dome over the coil than some of its competitors, not that this is bad thing just an observation.



To keep the overall height profile of the tank down Wotofo provides you with an optional bubble glass tank. Whilst it increases the capacity to 5ml be aware it increases the diameter significantly from the tanks base (25mm) out to 28mm leaving it sitting flush with the edge of the Flux box mod, so I re-iterate buying a vape band is advisable as the mod wobbles easily.

The tank breaks down into 5 pieces, you get three 10mm x 2.4mm airflow slots with an adjustable Airflow Control, the positive pin sits proud once you screw the coil in. Personally I would like to have seen this stainless steel pin gold plated to improve contact slightly.



I’ve experienced no leaking, nor condensation seeping from the Flow Pro tank throughout the life of both coils. It was good to see the black gaskets sitting flat on the coils with no wires poking out, the cotton also looked to be packed well once primed, very good in comparison to some company’s attempts at these sort of coils.

How’s it Vape?

The Flow Pro comes with two of the same coils (0.18 ohm mesh coil). They are rated between 40-60 watts. I found the stated resistance to be accurate (+/- 0.02 ohm Variance); the coil break in time (to get rid of that horrible cotton taste) to be quick at just 4ml.




As with other mesh coils I had to put a good 20ml of juice through the coil before I was able to push the wattage past 45W otherwise I was getting a burnt taste. After this initial break in period I was able to push the coil to around 55W which is slightly under their stated range, but ample for a warm vape.

The airflow is fairly lose through the coil which makes airflow adjustment necessary especially at the lower wattages in order to get the most from it. You will notice it’s loud on the draw wherever you set this so don’t expect to stealth vape anywhere, in fact next door will likely hear you vaping as you do need to pull on it quite hard to keep the coil from cooking.

I’ve settled on vaping this tank with the airflow control ring (AFC) set at roughly two thirds open. In my opinion the mesh coils provided are more suited to those who prefer clouds and a decent lung full over flavour. I noted that the vape is quite dry on the tongue but juice does seem to last for a good while so depends what you are after here.

I ended vaping at 55W which is where I felt it had best balance of cloud and flavour. The coil lasted about a week with my own DIY liquids which are not high in sweetner which is disappointing.

Tank Pro’s

• Decent vapour production
• Fast coil break in time
• Spot on match for the mod
• Decent capacity 4 and 5 ml
• Compatible with all the baby beast coil size options
• No Leaking (coil dependant)
• Doesn’t get hot at 45W chain vaping
• Shorty drip tip is comfortable to use
• Takes an 810 (although it needs a short base - the recurve drip tip works)
• Accurate coil wattage range and stated resistance was within tolerance (+/- 0.2 ohms)

Tank Cons

• Huge unnecessary packaging (ill list it here so it won’t be listed again)
• Lack of adequate spares in the box (ill list it here so won’t be listed again)
• Would like to have seen an indicator on the top cap as to where to push it
• Top cap was a little stiff to push back
• Refilling requires wiping away excess juice after a refill
• Flavour on the Mesh Coil was average (but this is personal as I don’t like mesh)
• Coil life was disappointing
• Could benefit from a 510 drip tip adaptor
• Poor quality control across parts of the atomiser
• O-ring holding the drip tip was too lose
• Big rubber O-ring had stuck to my glass making 1st disassembly difficult
• Noisy draw

Flow Pro Tank - Final Conclusion



Ok this tank has some issues, I don’t particularly like mesh coils anyway due to the lack of flavour fade with them, so I’m doing my level best to put that to one side and remain impartial with my closing.

I find this tank offers average flavour performance but a decent lung hit and vapour production, it’s not awful by any stretch and gets the job done but it’s not enough to get me excited.

Unfortunately there were quality control issues I’m not particularly impressed with. Now you could argue; “but it’s a starter kit” KingPin!…what’s the big deal?, well I’ve seen other companies release similarly priced products and make a concerted effort with quality control so that’s no excuse.

Overall the Flow Pro just feels like an afterthought rather than a bottom up design. In fact I swear if I vaped this blindfolded with the same drip tip next to the Eleaf Ello Vape tank I wouldn’t be able to tell them apart (I wasn’t fond of that one either). This tank uses a template I’ve seen over and over again since if been reviewing and to be honest I expect more from these two big names especially with their product line ups and experience to draw upon.

Build Quality and Impressions

Let’s start off with form factor, ergonomically the mod has the ingredients to be one of the more comfortable to hold out there: rounded edges, slim line, smooth yet grippy paintwork and a fire bar that’s responsive almost its entire length leaving it with the ability to use either way around in both hands, except I don’t find as comfortable to hold as I should because the screen sticks out exactly where your palm rests in addition the plastic buttons used for up and down (and the replicas on the back) extend up in crevices all the way to the top plate which leaves it feeling a little jagged on your fingertips. I think the team placed too much emphasis with the colour and eye pleasing aesthetics.





Actually these crevices housing the up and down button s bother me in another way as well …look at the front there and how they have been designed starting at the top of the plate running nicely angled down into a single channel. Imagine now a juice leak here (happens to all of us at some point) the juice will nicely follow the crevice all the way down over the buttons and if there’s enough it will end up being fed to the USB port guided by its very own landing light strip just to finish the job.



Speaking of the light strip and finishing up my thoughts on the aesthetics; it’s not overly obnoxious like I’ve seen on some mods and suits the namesake well especially set to flash on fire only, it’s a bit like the flux capacitor in “Back to the Future. Do I use it however? No not really it’s for looks and like all mods with flashy lights I switch them off immediately to save the tiny amount of battery juice they drain.

Now focusing on the top of the mod and the high gloss plastic plate; it’s a strange choice especially for a box mod sitting in the upper end of the medium price range. I was going to go nuts on this point because tanks sit flush on top and mark it (like mine did below), however Wotofo do provide a protector which sadly I found afterwards, so be sure to use it and definitely try not to lose this if you want to keep it neat and tidy because you get just the one (it fits 25mm tanks flush).




The mod does feel solid and well-built despite the plastic areas, it’s hefty at 308g (with the tank and batteries loaded). In addition I also like that it has a centre mount and that it can house 28mm atomisers without overhang.

The 510 positive pin is gold plated but has very little throw to it. I measured 4.08mm before pushing and was only able to push it down approx. 1mm more, so do watch out for long threads or perhaps consider using a thermal disc under such atomisers.



The screen is ridiculously dark, if there is any sort of daylight or even a spotlight like my picture below you will struggle to see it, much like the Smoant Ranker they used a dark plastic casing which dulls the screens brightness sitting behind it.



The buttons work fine there’s no rattle on mine except for the fire bar. Whilst mine doesn’t audibly rattle per se (unless you flick it), it does have a little sideward movement. It feels like its sitting over a spring that doesn’t offer enough resistance. Unfortunately unless I’m being thick I’m unable to strip the mod down to take a peek underneath to confirm for you (another reason a major leaking event bothers me).

I found I had to be careful whilst holding the mod and typing on my phone because there is no way to lock the wattage currently set. Whilst this isn’t a normal feature on mods; as with the screen the “up” button sticks out enough to catch it; and with the screen being so dark outside I’ve taken more than a few hits unexpectedly at 200W!...I assure you on a 55W mesh coil that’s not a pleasant experience.

The battery door is a hinge and slot jobby, it’s really quite tight to get in place and I sometimes struggle to pull it out and put it into position because the hinge is unnecessarily wobbly. I also find the holding slots a little short meaning accidental knocks could cause the door to open when you don’t want it to. I haven’t had it happen to me yet, but the catch lip is very small and will wear over time.




The paintwork is the same powder coat as the tank and will chip easily over time so watch for keys in the pocket.

Modes and Usage

General Comments and Observations

• The Flux adjusts by 1 watt increments, there is no round robin when you reach the end, it doesn’t start skipping when you hold it so it can take a while to up to, or down from max wattage.
• At the time of writing this review I don’t believe the mod is firmware upgradable.
• On screen information include, wattage, Battery level, resistance and output voltage
• The mod is not instant on, you do need to wait a few second for the Wotofo load screen

Navigation:

• 5 clicks of the fire bar for on or off
• Press Fire Bar and down button together to access “Colour Menu Options”
• Press Fire Bar and Up button together to cycle through Normal, Powerful and Powerful + mode
• Hold Up and Down button together to lock/unlock the mod

Colour Menu Options:

• Two Colour menu options include Working light and Standby light.
• Working Light – choose from 7 available colours, press fire bar to select how they will display when firing the mod, or set to off.
• Standby Light – you get to choose how the light bar displays after firing until a timeout period expires. You cannot select a colour here it will go through all of them like a rainbow.

Wattage (Power & RTC mode)

I haven’t had any issues with resistance readings on this particular mod. I allow pre made coils to have a tolerance of +/-0.02 ohms and mine was consistently reading bang on 0.18 (target resistance) or 0.19 with the other one. It was also reading my other atomisers I tried accurately as well.

The Flux fires quickly, almost as soon as you press the fire button you’re off, at least that is with Flo Pro sub tank. Combine this with the Powerful + and it’s great, the output feels really tight in line with my YiHi Q Mini up to 80W (which is my favourite wattage chipset). I vaped using both mods side by side switching the RTA over between vapes and I have to say even in standard mode (vs the novice mode on the Yihi) I was getting a slightly faster ramp up on a 0.13 ohm build on the Flux and the power doesn’t feel spongy in the least I’m impressed..



The same was true at the lower wattages around 40-60W with my single coils (both fused clapton and framed staple) around the 0.23ohm mark. I was really happy with the responsiveness from this mod in this respect.

Once you start to expand out and use more exotic coils (helix, staple staggered fused claptons etc) and push it above 120W in a dual coil configuration it starts to wane a little and I did notice it took a little more time to get the coil started, Yeah I know more coil mass and all that, but still it took more time than it should. This isn’t to say its “off”, it still hits well, certainly up to 115W once it gets going, but that initial fire ramp up responsiveness I observed with the flow pro and lesser dual coils wasn’t there even in powerful + mode.

Does it get to 200W…no I don’t think so not compared with my YiHi (that is seriously bloody hot at 200W) this one I was able to take it albeit briefly but I lack bench testing equipment to verify right now. I do know 200W didn’t fry my Flo Pro coil when I took a big hit by mistake on four separate occasions if that helps.

So it depends what range and what coils you want to use to vape with on this one.

Finally I also noticed I had to firmly press the fire bar, whilst it isn’t difficult to engage or even that it has a deep travel, I found the power comes in and out during the inhale if I didn’t.

Charging

I recorded the low cut off at 3.2V and the good news is I was recording that exact figure across both cells so mine is discharging evenly.

Wotofo states that it has a charge rate of 1.5A so in my book the Flux should charge to full in about 2 hours 30 minutes, however it only charges to approx. 4V in that time at which point the screen starts flashing as full. If you continue to wait it will continue to charge until the screen turns off completely. With this second process taken into account; it takes the total charge time to approximately 4 hours from cut off using my Sony VCT5A cells (2500 mAh). I imagine there’s temperature sensing on the board slowing the charge rate at points as the mod stays relatively cool throughout.

I did record the full charge cut out at 4.22V again dead even across both cells. Most companies (even well-known charger companies) aim for +/-0.03V detection so it’s within its range. I’d like to see it cut out just below 4.2V (around 4.18V if anything) but it’s nothing to write home about, therefore I shall pass on board charging as good for the flux although as always I prefer charging externally outside of reviews.

On a final note the mod does not support pass through (ability to use it whilst charging), in today’s line up of mods this is unusual so ill record this as a con.

Mod Pros

• Atomisers sit flush
• Centre mounted 510
• Can accommodate up to 28mm atomisers
• Power mode works well up to 120w (I don’t really vape above that wattage sorry)
• Very responsive
• Accurately read resistances
• Firing bar works well in either hand
• Very simple menu system
• Handles charging/discharging accurately
• Doesn’t feel cheap, feels solid
• Grippy paintwork on the sides
• The light bar isn’t obnoxious

Mod Cons

• I imagine paintwork will chip easily over time
• Top plate is a strange choice scratches easily (same as all plastic areas on the mod)
• Cannot be stripped down easily
• Questionable whether ill stand up to leaking well
• Screen cover is just too dark
• Short throw on the 510 pin (it’s pretty stiff)
• Edges of the fire bar, crevices, buttons could have been more rounded
• Does it reach full 200W …I’m not so sure it does
• Finger print magnet screen and back panel
• Does not support passthrough (charge and vape)
• Had to make sure I held the fire bar tight to engage (too much wobble in it)
• Battery door hinge was a bit lose made it harder to lock door in place
• Latches on the battery door are too short
• Wobbles easily watch for knocking it over with the Flow Pro’s bubble glass in use

Final Conclusion part 2 – Flux Box Mod

I’m torn on this mod; I think mine performed really well within the wattage range I mentioned in my review, in particular I was impressed with the responsiveness and non-spongy hits I got from the power mode, paired with the Flow Pro tank it’s a bit of an animal.

Now would I say the same if I was a high wattage vaper using complex coils on Rebuildable atomisers most of the time… hmm no I don’t think I would. In addition despite the mod feeling well built, there are design choices and areas that could have been executed differently and more mindful of the end user.

So I think it’s best to end this one with do plenty of research, as always take my findings, those of others in the forum or comments below, other reviewers out there and pick out the bits that are important to you and go from there as Imagine this one will be divisive.



Thanks for taking the time to read my review, I hope the information serves you well…. until next time KingPin!

I love my Flux mod, but I'm very disappointed that the bottom door latch has broken. I'm not sure what happened, I popped it open like I always do to change the batteries out and a small piece (tiny even) of the metal fell in to the palm of my hand and now the door is loose from the device and can't be latched.

Does anyone know if you can buy parts?

Unfortunately it’s highly unlikely is it still in warranty?
