Sigelei 150W Intro

Sigelei has done it again! Replacing the Sigelei 150W, a hugely popular box mod, the Sigelei 150W TC is a relatively affordable dual 18650 mod with 150 W and up to 100 joules of TC power—what more could we ask for, especially considering it works as advertised?

We can’t ask for much more at this price range, but there are a few things I would like to see changed in the next version, but all in all, it’s a fantastic-performing device that is hard to knock and easy to recommend.

Let’s take a look…

Notable Remarks

Ease of use

The vape industry as a whole is making it so the ease of use, with what could be considered APVs (advanced personal vaporizers), is getting incredibly easy—it’s almost hard to call this mod “advanced”. But let me tell ya’, the chip in the Sigelei 150W TC puts out! At a max of 150W in regular power and 100 joules in TC, most will have ample headroom to tune into exactly what they want, and its ease of use makes it a device that virtually anyone could use regardless of their vaping experience.

A simple rundown of the how to use it: 5 clicks to run and you’re in regular power mode. Once the mod is on, to switch over to access the TC functions (or to turn off the mod), click the fire button 5 times and then scroll through the menu using the fire button and use the +/- buttons to do the selecting. To set the atomizer resistance in TC, just press the +/- buttons simultaneously for a second or two.

I’ve seen one review–a really good review–that states that the mod is too easy to accidentally get into the menu system when turning it on because to access both functions it requires a 5-click feature, but I have not had any issue with accidentally getting into the menu when I didn’t want to (as that would require 10 clicks). That said, it is a bit of an odd choice to use the same feature to access both functions.

Build Quality of the Sigelei 150W TC

It seems to be built well, but I will not be dropping it any time soon to test out how well it’s put together. But for other high-wattage mods in this price range, I’d say this mod is built better than most of what you’d be able to find, if for no other reason than its all metal construction. I wouldn’t say it’s built like a tank (though it might look like one), but it’s far from feeling cheap.

Ergonomics

While some may find the Sigelei a little big, it’s essentially the same size as all the other high-wattage dual 18650 box mods (the Sigelei 100 W and 150W, the IPV 3 and 4, etc.). But, I think that the actual economics of this devices makes it much easier to hold vs. some of its more boxy counterparts.

The Sigelei 150W TC is basically built on a c-frame (though I am not sure if it is considered a c-frame). The side underneath the 510 is rounded, which is perfect for the fingers’ natural gripping position and this is further enhanced by a recessed grip pattern built into the surface. The rubberized finish puts the final touches on the this mod’s ergonomics that allows the user to feel confident in having a firm handle of the mod.

Aesthetics

It’s hard for me to imagine how others will feel about the look of the device, but from reading various reports, it’s as simple as some love it and other don’t. One of the major points of contention is the atomizer platform that breaks up the top surface of the mod. I don’t see a point to it being there, but it does add to the device’s signature looks and it gives it a semi-smaller profile. Judging by how popular this mod so quickly became, I guess most have no qualms with its looks.

Overall, I think the Sigelei 150w TC looks tough, but I am not all that much a fan of its looks—especially with an atomizer on top. However, for me, this isn’t a mod to buy for the looks, it’s a mod to buy for its functions and power, its feel, the ease of use and its relatively inexpensive price tag.

Sigelei has recently released various colors—white, red and tiffany blue—for those that do want to jazz it up a little, so the newly released colors should allow for a bit more pizzazz. I think the red and the white look SUPER slick, but the various colors do take away a bit from its rugged, industrial quality.

A few quirks with the design/construction

Sigelei 150W TC Seam
Sigelei 150W TC Seam
  • There are little seams that run around the atomizer connection, all the way down the back and the sides to underneath the mod. I don’t know how well sealed off these are from the electronics of the mod, but I can tell you that if you get liquid down in these seams, which is more than likely, liquid will travel down in there and it’ll be hard to fully clean out. I just hope that my electronics are sealed off from this.
  • The rubbery finish on the mod looks and feels great, but if you get liquid on it, which is more than likely, it is hard to clean off with a simple paper towel. It’s difficult to explain, but when you wipe the mod, it’s like you’re only smearing the liquid. It’s best just to take a wet wipe or something and then dry it with a napkin (or similar).
  • The magnetic battery door. The door is meant to be easy to take off and change out the batteries, which it is, but it comes off far too easily and has so much give that it can be flicked off with my thumb while holding the mod. This should be held on by much stronger magnets!
  • The battery compartment and copper connections are tight as hell! Seriously, I feel like a damned Tokyo Subway Pusher trying to get my batteries in! If you are not strategic with how you put your batteries in, you’ll damage the wrapper on your batteries. That is not a good thing and I’ve got three batteries now that have to be re-wrapped before I’ll feel confident in continuing to use them. I’ve since learned to be careful when putting my batteries in.
  • When adjusting the power or even after firing the mod, the screen buzzes until it goes black. It’s not all that loud, but I can hear it. Then again, I have the hearing of a paranoid k-9, so I doubt anyone else will notice it unless putting the mod up to their ears. Wait…what was that? Ruh-roh!
  • When I got the mod, putting the batteries in caused sparks inside of the battery compartment. It stopped happening after a few days of use, but while it was happening it made me feel uneasy.

Note: I have not seen any reports about other having damaged the wrapper on their batteries or having seen the sparks while putting the batteries in, so maybe, just maybe, it is just my unit—or others haven’t spoken on it or noticed it. I can only honestly speak on my experiences.

The Manual of the Sigelei 150W TC

It’s well written (and has several sections for other languages). It’s short, descriptive and to the point. It doesn’t leave anything left uncovered! All you’ll need to know is covered in 9 small pages. You can find the manual here.

Temp Control/Power

​I am not a techie; I am just a vaper that tries to write about my experiences with a given device. As a vaper, what I can say that you may find of value is that this mod puts out some serious power you can feel, and in TC mode, it has had no glitches and does exactly what it is supposed to do.
Note: the chip (used in this mod) only supports nickel while in TC. It would be nice to see it support Titanium wire, but that would be up to the makers of the chip (which I believe is Yihi).

Screen

The screen is not as bright as I would like (like the SXmini M-Class), but the layout is spectacularly easy to understand. I love the layout of the screen! It’s just very easy to get the overview of it all…and at a glance! It’s set up in quadrants that, in regular power mode, show the percentage of the battery’s charge, watts, volts and atomizer resistance; in joules/TC mode, you see the joules, temperature, volts and resistance of your coil. In both power and TC mode, there is also a battery icon, indicating how much juice is left, which is easier to read at a distance.

The 510 Pin

Spring-loaded copper 510 pin. Every atomizer have screws down flush.

Buttons

Hmmm…The buttons are okay, but as imposing as this device looks, the firing button is a bit flimsy and a little to flush to the mod for my taste—though the firing button does have a relatively nice click to it. I feel the fire button could’ve had a more dominant presence and more of a petal-to-the-metal feel when firing at such high wattage. I’ve seen worse, I’ve seen better.

Likes

  • Priced inexpensively
  • Loads of power
  • Easy to use
  • Works as described
  • Feels wonderful in the hand
  • Rubberized finish
  • Substantial battery life
  • Rugged looks
  • Screen layout is easy to understand
  • Comes with a silicone sleeve to protect the mod’s surface

Dislikes

  • Battery door comes off too easily
  • Plane-jane firing button that is a little too little
  • Super tight space for batteries
  • Screen could be better lit

Verdict

If you are in the market for a high-wattage/TC box mod and you got $100 to spend, this mod should be given a strong consideration. It provides a helluva lot at a good price point.

    Very good review. I got this for christmas and it seems more powerful than my very carefully taken care of sigelei 150w. The chip is spot on….i too wish this did more than Ni tc but still an amazing mod. Oh, i also rick mine….naked.

  • Kerry Maxwell

    I would nitpick the settings interface a bit, as it seems a little fussy when trying to edit resistance, joules, etc. I’ve seen videos, but my unit seems a little less responsive to button pushes. OTH the magnets on the battery door seem plenty strong and have resisted any casual thumb movement with my medium-large thumbs. My concerns are reliability of the electronics, but time will tell…

    No silicone here either.

    • Jeremy

      How much is this mod going for these days? It seems almost crazy to think of this as a $100 now. LOL

      • Kerry Maxwell

        I think I paid just under $70.

      • Josh Ogle

        I must’ve gotten lucky bc I only gave $20 for mine and it even came with 2 new batteries, 5 new coils , and a sleeve.

  • Josh Ogle

    I have this mod and I absolutely love it. Although I totally agree the battery door is super loose and one of the magnets came off so I had to reglue it back in its slot. But other then tht I’m really pleased with it.
