Project Square 50w Box Mod Review | Vape Mod Review

A subdivision of venerable vapemakers Project Sub-Ohm, Project Square has the stated goal of turning out highly functional and stylish devices at an affordable price, and the latest product of this belief is the Project Square 50w Box Mod.

Some might look at the $50 MSRP of this value vape and assume it’s the most attractive part of the package, but the Project Square 50w also features an advanced internal chipset and ergonomically designed body for comfortable all day use, features we usually see on mods costing nearly double.

Is this ambitious offering an irresistible deal or an example of only getting what you pay for? Find out in today’s Project Square 50w Box Mod Review.

What’s New- Project Square 50w Box Mod

The 50w Box Mod from Project Square is built as a premium value vape, made from high grade aluminum and featuring top quality finishing such as 24K gold plating at the posts and connector pin for optimal conductivity.

Its custom-spec YiHi SX330 internal chip regulates its 50 watts of power with precision, and enables firing of custom builds down to 0.2 ohm.

Throw in an eye-catching design and comfort-friendly form factor, and you have a seriously compelling entry level piece that doesn’t feel basic.


The Project Square 50w Box Mod takes two High Amp 18650-type batteries, and they work in concert to extend the active life of the unit.

Variable Wattage

Wattage levels can be adjusted from a base of 7 watts to a maximum output of 50 watts to allow easy customization of vapor temperature and flavor.


From a performance aspect, the Project Square 50w Box Mod is more than adequate. Vapor production and flavor were both above average with this unit, and we experienced the best results at power levels ranging from 30 to 40 watts with the majority of juices.

This unit fires reliably, although with a slight delay, and as promised, it fires builds down to 0.2 ohm with no problem. Sure, there are better performing devices on the market…but they’ll usually cost you about two or three of these, and for that factor alone the Project Square 50w merits a level of praise.

Build Quality

As for build quality, the Project Square 50w also acquits itself fairly well. To its credit, it’s an overall solid feeling device with a wider than usual feel in the hand if you’ve been using Box Mod X for quite some time.

The OLED screen is rather large and brilliantly lit, providing a reliable display even in natural light and recessed to minimize scratches. The black exterior finish is sharp, and the red anodized accents add welcome flair.

We will, however, say that the buttons could be a bit better.


The 510 threaded contact pin of the Project Square 50w Box Mod is adjustable and plated in 24K gold for maximum conductivity.

This not only looks great and gives us something to talk about here, but helps to extend the unit’s already healthy battery life by increasing the efficiency of its operation.

Aspire Triton

The Aspire Triton is one of the hottest tanks of the year, and for good reason. A top filling design and crazy airflow not enough for you?

Then how do a 5mL capacity and organic cotton coils for unbeatable flavor strike you? We did an extended feature on the Aspire Nautilus Triton here on BC recently, so have a look if you’re interested in one of 2015’s top tanks.

Kanger Subtank Mega

Speaking of tank royalty, very few discussions of the best of the market take place without a mention of the Kanger Subtank line.

Oversized capacity is the special feature of this iteration, but like the original Kanger Subtank, it features the outstanding airflow and flavor-packed draws that have made it into the first family of hybrid tanks.

Check out our full Kanger Subtank Mega Review for more information on this class-leading tank.


Compare With…

Innokin Disruptor

Innokin has cranked out hit after hit since it introduced the original iTaste, and the Disruptor might be the manufacturer’s most innovative design yet.

The core of the Disruptor is the proprietary InnoCell battery, which is designed to be more powerful and reliable than conventional battery types as well as enabling the easy-access Slide and Lock system to make hot-swapping of batteries a breeze.

We took a long look at the Disruptor here on BC, so head past the link to see what we think of the latest generation of Innokin’s work.

Eleaf iStick 50w

The Eleaf iStick 50w is another sequel in a popular series, offering 50 watts of vaping power through a high capacity 4400 mAh battery.

The iStick 50w also features USB charging as well as passthrough technology to enable use during vaping.

The Eleaf iStick 50w was yet another of the devices to earn its way onto these pages, so check it out to learn more about this capable little mod.

We Would Have Liked to See…

The Project Square 50w Box Mod offers plenty in the way of value, but that also means making some sacrifices in many cases.

With this mod, that means a slightly lower overall build quality than some of the top mods on the market even though the fact that they even compare from a performance standpoint is a profound compliment.

The battery bay door is also secured by screws, and we’ve really developed an affinity for magnetic doors around these parts. Another minor issue is the machining of the 510 threading, which can be a bit wobbly but is otherwise okay.


All things considered, it’s hard to beat a fully featured 50 watt box mod for $50 or less, and that’s exactly what we have here with the Project Square 50w.

While it’s not really a top of the line model, we’ve seen units costing far more do a lot less while looking and feeling significantly worse than the Project Square unit.

Advanced vapers, power freaks and competition cloud chasers may find that they need a bit more power, but the Project Square 50w Box Mod is perfectly suited as an everyday device for most users.
