IPV4S 120W Box Mod

Ease of Use

The IPV4 from Pioneer4 You was a great mod but, according to some, had some issues. Well, the company has improved on the previous version, fixed the bugs, and released the new and improved IPV4S with more firmware upgrades and features that vapers who prefer temperature control mods will flip for. Read on to find out more about it.

IPV4S Testing and Performance

The IPV4S is quite an impressive piece of vaping hardware. It comes with upgradeable firmware, a host of built-in user protections, and the ability to vape in wattage, voltage, or temperature control mode. One improvement is the Yihi SX330 V4SN chipset which enables the wattage to max out at 120W instead of the previous 100W. The increased safety settings, as well as the ability to choose TC memory modes, makes this a great mod for the money. Here is some information about the mod and a look at how it operates.

  • Yihi SX330-V4SN chipset
  • Spring-loaded 510 connection
  • Dimensions: 108 X 58 X 26 (mm)
  • Power in Joules: Ni wire: 5J – 50J
  • Power in Joules: Ti wire: 5J – 100J

Build quality and Design

The mod is constructed from an aluminum alloy and feels very sturdy. It looks almost identical to the IPV4 except for a few small changes. The battery door cover is textured and held in place with ball bearings instead of magnets, and the OLED screen is not tinted like the previous version making it clear and easy to read. The battery cover is easy to remove to change out the batteries and the edges of the device are rounded off for a smooth easy grip.


The device is very durable and would survive a few drops to the floor. I accidentally dropped mine getting out of the car because I had set it in my lap and forgot to grab it before stepping out. It landed in the dirt but didn’t get so much as a scratch on it.

Ease of Use

With all of the built-in protections offered by the device, it is very safe to use, but I would not recommend it to new vapers because of the temperature control restrictions. This is more for advanced users who understand Ohm’s Law and wire resistances. That being said, it is fairly easy to use once you adjust the settings to your liking.

I tested this device in wattage mode only since I didn’t have any nickel or titanium coils on hand for TC mode. I don’t really use it all that much so all of my tanks and RDAs take Kanthal wire.

I do like the fact that it has different temperature control modes for those who use it. You can choose to use it in wattage mode, voltage mode, or TC mode in Celsius, Fahrenheit or Jules. Plus the ability to set up to 5 memory modes.


The IPV4S feels good in the hand with the material grip and power button on the front of the device. It feels very natural and very comfortable to hold.

Features and functions

It has a USB port for firmware upgrades (not for pass-through charging). There are a number of built-in safety features that I think are fantastic. A few of these are:

Low Voltage Protection
Low Resistance Protection
Reverse Battery Protection
Short Circuit Protection
Temperature Overheat Protection

Wattage and Power

The maximum wattage for this device is 120W with a minimum resistance of 0.1ohm – 3.0ohm for Kanthal, and 0.05ohm – 0.30ohm for nickel and titanium coils. It has plenty of power for any of your atomizers. I used a 0.5-ohm atomizer at 65W and got a really nice, cool vape with plenty of cloud production. I took it up to 80W and it started getting a little to warm for my tastes, I think 65 is my “sweet spot” with this device. If you like warmer vapes with a lot of vapor then you’ll love this mod.

Battery Life

The battery life of this mod is good. I vape a lot throughout the day and only have to charge the batteries at night, so it is really good in my opinion. For someone who vapes less frequently, you could probably last a couple of days between charges. It takes 2 flat top 18650 batteries with an amp rating of 25. I recommend Samsum 25R, LG HG2, or Sony VCT4 purchased from a reputable vape shop or online supplier.

What We Liked

+ Safety features
+ More TC modes
+ OLED display is brighter
+ Comes in black and silver

What We Didn’t

The battery cover is a little flimsy


The selling price for this new and improved IPV4S is less than $60, and with all the improvements and safety features, it is worth every penny. Similar devices with some of the same features are priced between $80 – $100 so this is definitely a good value for the money.

Final Verdict

The IPV4S comes with safety features and all the bells and whistles of higher-priced box mods. And with all of these improvements, it also comes at an affordable price. It is a good value at under $60 for a well-made device that works on the level of a high-end mod. I would recommend it to advanced vapers who like to use temperature control and want more customization with their settings.
