After the Aromamizer Titan had gone to #1 with a bullet among my atomizers, I was made aware that Steam Crave were also offering a matching mod. The Titan PWM.
I had been considering a fifth mode for the "just reach left and grab one" array next to my keyboard, yet no appealing mode had materialized.
My Fat Boy is sitting on a variable-wattage mod, the SMOK GX350, simply because nobody had been offering a four-battery, 300+ W machine, and I do often run it at it beyond 300.
Variable wattage mods, in my experience, are just unnecessarily complicated, and while they may have many neat features, often don't handle quite as nice as a simple, straight-forward VV mod.
Mech mods, meanwhile, be they "real", with nothing more than a battery cradle and crude switch, or hybrids with a mosfets, require more thought to be put into building coils, lacking any adjustability.
However, my beloved Dovpo M VV, would get fairly warm with the Titan atomizer, even far below 300. Even with the heatsinks, I'd be pouring about 130 W through there, in addition to which Li-Ion batteries heat up under heavy discharge.
So when I found I could get a good deal on that Titan PWM mod, I thought "Yeah, that looks kind of okay."
And it does, doesn't it.
Four batteries, two parallel pairs in series. But a lot of features that other VV mods lack. For one, instead of requiring a screwdriver to adjust power, the knurled firing-button is also the power-knob. It is stepped, both tactile and functionally, allowing adjustment in steps of 0.1 Volt. Which is good enough.
The display, meanwhile, shows the charge of each battery pair, set voltage, detected resistance, and the resulting wattage. I'd prefer amperage to wattage, but that is good enough.
"PWM", btw, is short for "pulse width modulation", which is the simple and straight forward technique by which as many as 8.4 V on a full charge is turned into a lesser voltage. It does it just the way the name implies. The full voltage comes out in discrete pulses, at a fixed frequency. Depending on the width of said pulses, this works out at a lesser effective voltage.
It cannot produce higher voltage, like some VW mods can do with fancy step-up circuits, I don't need more.
It can run as much as 300W, according to the specs, with a max output of 60 Amps. While the box also specifies 45 Amp input ... I think they mean it'll draw no more than 45 Amps from either battery pair.
Critically for the home gamer, it has all the safety features that most advanced-class VV devices lack. It will consider anything below 0.06 Ω a short circuit, which is pretty good (most mods with such protection won't handle less than 0.1 Ω), it will prevent deep-discharge by rejecting battery voltage below 5.6 V. That is very low, though, working out at 2.8 V per parallel pair. All my other mods complain about low voltage at something like ~3.2 V.
Having twice as many batteries to share the discharge current, and all that thermal mass, should make operation even without heatsinks entirely comfotable, while having twice the ampere-hours will obviously interrupt my vaping less often, for battery charges.
The firing button looks a bit cheap, but feels fine. The fit and finish of all other parts is entirely up to snuff. And with all the safety features and convenient display information, it is definitely suitable for people who never used a VV mod before, yet don't have/want the equipment to measure their atomizer resistance and figure out whether it'll be fine for the mod.
If you order from China, you can get one of these for about $50. I paid a little, but not much, more, ordering from Britain.
Caveat: As I learned from reviews. The serial number stenciled on the back of the machine is important. Early production had some difficulties, apparently, and probably shouldn't be operated. There was, apparently, a bit of a recall. Dunno exactly what the issue was, but once they had fixed it, they added the prefix "A" to the serial number. I have that, so I feel safe and fuzzy. Anyone finding themselves with a unit that lacks said prefix should apparently get in touch with Steam Crave directly, and they'll sort it out.

If there were absolutely anything to be afraid of, don't you think I would have worn pants?
I said I have a big stick.
