Sigelei 100w v2 Review | Vape Mod

Sigelei has built its reputation in the vape game with far more hits than misses.

Although the original version of their 100w Box Mod was a fairly well-received model, over time a few quirks and outright flaws ended up limiting the lasting impact of what is overall a very capable device.

Enter the Sigelei 100w v2, which endeavors to improve upon the total package offered by the unit.

Featuring an updated look and profile to go along with a host of internal upgrades meant to make the Sigelei 100w the device it promised to be on release day.

For this reason, today’s Sigelei 100w v2 review will take a special focus on what, if anything, makes it a better long-term prospect than its predecessor.

What’s New- Sigelei 100w v2

Along with a redesigned zinc exterior, the Sigelei 100w v2 has a new button input system as well as a spring-loaded copper contact pin.

Another change to this version of the Sigelei 100w is the back plate, which can now be secured fully magnetically as well as with the older screw


The Sigelei 100w v2 features a spring loaded copper 510 contact point. This allows it to be used with the majority of new items that your local vape shop associate will insist that you try.


The Sigelei 100w v2 is powered by not one, but two 18650 batteries rated for 30 amps or higher. These batteries must be charged externally, as USB charging is not supported by the unit.

 Sigelei 100w v2 Charger

Nitecore Intellicharger i4

When you’re dealing with the type of powerful (and potentially expensive!) batteries required by the Sigelei 100w v2, tossing them on any old cheap charger just isn’t the answer.

If you’re going to shell out for a premium vape and the premium batteries that go in it, you need a premium power station to keep everything juiced up, and the Nitecore Interllicharger i4 more than fills the bill.

The Intellicharger may be the last external battery charger you’ll ever need, featuring universal support and a long list of stability and safety features that ensure you can charge with confidence.

As soon as you pop your batteries onto the Nitecore Intellicharger, it automatically identifies the battery’s type and charging method using its four independently controlled microcomputer-regulated charging slots, delivering the ideal level and volume of charge the specific battery needs.

Best of all, when your batteries are done charging, the power is cut off to the individual slots and you get a nice indicator light so you don’t have to walk several feet to check a guage or anything.

Throw in reverse polarity protection and an optimized heat management system, and you have one of the finest and safest chargers on the market.

Best Clearomizer

Kanger Aerotank Mega

As if Kanger wasn’t moving enough units of its popular Aerotank family, it recently introduced a super-sized version for vapers whose number one priority is capacity.

The Aerotank Mega takes the line’s most popular features such as adjustable airflow and flavor-enhancing organic cotton coils and marries them with an absolute beast of a tank, measuring up at 3.8ml.

We’re already excited about just getting the Aerotank Mega in our hands, so stay tuned for more on this premium clearo as we continue to put it through its paces.

Aspire Nautilus Mini

Not really looking to take an entire sample bottle of eJuice with you? Maybe the Aspire Nautilus Mini is more your speed.

The Nautilus Mini shows off an adjustable airflow control system with four settings as well as a spring-loaded 510 contact pin for near-universal compatibility.

Iits bottom vertical coil design is engineered for the most efficient vaporization possible in the profile. We took a look at the Aspire Nautilus Mini here on BC, so check it out if this seems like your kind of tank.

Variable Wattage

The Sigelei 100w v2 offers adjustable voltage from 10 to 100w.

Wattage is cranked up in increments of 0.1 from 10-50w watts of its full power capacity, but from 50w onward the increments step up to a full watt because nobody vapes at 70.8 watts, you know?


The actual vaping performance of the original Sigelei 100w Box Mod was one of its strong suits, and this quality thankfully makes a return in version 2.

Vapor production and quality was good at a variety of settings configurations, although we were able to find a sweet spot with most juices and tanks around 40w.

We were also able to fire builds down to a resistance of 0.15, so tinkerers and cloud chasers are sure to have a ball with this one.

Build Quality

The build quality improvements were the most welcome upgrade of the Sigelei 100w v2. Most notable to the buttons, which have been redesigned not to stick when pressed at a slight angle.

Ever had a button stick on your Genesis controller during a round of Killer Instinct Gold? Minus the sadistic glee of your “friend” as he pummeled you on screen as your complaints fell on deaf ears.

That’s what it’s like to have your buttons stick on you in the middle of a vape session and we’re glad we don’t have to worry about that any more.

The magnetic battery door cover is a definite improvement, as most people do not carry tiny screwdrivers on a regular basis.

We also liked the addition of a spring-loading system to the contact pin, and copper plating is an excellent choice for conductivity.

Another minor improvement is to the battery contacts, which have been redesigned so as not to peel your battery wrapping when inserted even the least bit carelessly.


The Sigelei 100w v2 also packs plenty of safety features into the unit. With both high and low voltage protection as well as a temperature regulation system for added operational stability.

It also features reverse polarity protection to prevent the irreversible damage that can result from incorrectly inserted batteries in many units.

Superb Screen

One of the most visible features of the Sigelei 100w v2 is the upgraded screen, which now measures a hair under a full inch and features bright blue lighting.

This is an exceptionally informative display when compared with most other units, as it shows current resistance, voltage, and wattage levels as well as remaining battery life simultaneously.

Sigelei definitely gets extra points for making a comprehensive status report available at a glance even for someone picking up the unit for the very first time.

We Would Have Liked to See

The second coming of the Sigelei 100w is bound to attract a following, deservedly so as it is a well-considered update to an already popular model.

However, we would like to see USB charging support added to future models, as it’s just so darn convenient.


Overall, the Sigelei 100w v2 is the original version, except up-tweaked in every way.

Retaining the approximate size of the v1 was a pretty bold step in a time where everything on the market is shrinking, but it is nice to see that vape manufacturers aren’t making all their equipment for those with toddler hands and corresponding pockets on their clothing.

Sure, USB charging would have been nice, but we don’t think that’ll be a deal-breaker, especially for those who are already living without it. All told, the Sigelei 100w v2 improves significantly on what was already a very decent device, and we feel confident recommending it.
