Pioneer4You’s latest release is the IPV400, one of the smallest dual 18650 battery mods available, measuring in at 88mm x 41.5mm x 28mm, and it also features the new firmware upgradable Yihi SX330 F4 chip which packs up to 200W of output power and temperature control coil support, with a dedicated SX Pure mode for compatible Pioneer4You atomizers.

The IPV400 promises to provide a true 200W of power, and up to 120J of output power in temperature control, and there is support for Ni200, Titanium and Stainless Steel 304 wires in temperature control. There’s also a custom TCR present as well so that you can input the coefficient of certain temperature control wires and use them with the IPV400, and a smooth spring loaded sliding battery door gives quick access to the battery compartment.

Pioneer4You have consistently produced devices with solid build quality and accurate performance, is the IPV400 another one? Let’s find out…

What’s in the box?

The IPV400 comes in a smartly presented presentation box, and alongside the unit you will get a USB charging cable, a user manual and a warranty card.

Looks and build quality

Measuring in at 88mm x 41.5mm x 28mm, the IPV400 is one of the smallest dual 18650 battery devices out there, and has been designed with ergonomics in mind, right down to the curved edges and positioning of the buttons.

A spring loaded sliding battery door is located at the bottom of the device, which gives smooth and easy access to the battery compartment, and the location of the USB port has been well thought out meaning that you can charge the device whilst it is standing. The USB port is used for charging and upgrading the firmware.

When it comes to appearance, looks are very much subjective and personally I feel that the IPV400 is not the best looking mod out there, with ugly looking ridges at the side of the device and the small OLED screen placed in a rather awkward position on the IPV400. The OLED screen is one of the smaller ones out there, especially for a device of this size, and shows the power level, wattage, resistance and output voltage.

One aspect of the design in particular that I wasn’t a fan of was the central position of the 510 connector, I feel that just looks out of place and awkward, and would have looked far better placed towards the top edge of the device. It feels a little cheap in hand, with clicky rattly buttons as well, and the finish is also prone to picking up scratches easily so you may want to invest in some sort of protective case or wrap if you wish to look after the finish on your IPV400. That being said the rounded edges do give the device a comfortable feel in your hand, so although it isn’t a terribly good looker it does feel nice in hand.

Using the IPV400 and the Menu System

  • 5 clicks will turn on the IPV400. A further 5 clicks will take you into the menu system.
  • Up and down buttons will enable you to change the power setting and adjust menu options.
  • Power on/off gives you the ability to turn the device off.
  • Power and Joule mode allows you to switch between power and temperature control.
  • Temperature limit is set through the menu system.
  • You can select whether you are using an Ni200, Titanium or Stainless Steel wire, and also gain access to the custom TCR input.
  • You can switch between celsius and fahrenheit.
  • Current firmware version is displayed after celsius/fahrenheit selection.
  • Exit will take you back out of the menu.
  • To calibrate a temperature control wire, ensure both the IPV400 and the atomiser are at room temperature, then hold down up and down to lock in the baseline resistance

Performance

The IPV400 is one powerful device, with up to 200W of power at your disposal in power mode, as well as resistance read down to 0.15ohm, which means that the IPV400 is perfect for just about any type of usage, from sub ohm cloud chasing to mouth to lung vaping, and I found it to offer smooth and consistent power output with accurate resistance readings.

Temperature control is present and correct, with support for Ni200, Titanium and Stainless Steel, resistance read down to 0.05ohm and 10-120J of adjustable power output available. I got very stable and accurate performance in temperature control, with no resistance spikes and near perfect dry coil protection. Although stainless steel is listed as a compatible wire in temperature control, it’s actually 304 stainless steel compatibility rather than the more commonly used 316 stainless steel. If you intend to use 316 stainless steel wire you need to enter the coefficient through the TCR setting to enable usage, which may confuse some users. SX Pure compatibility is also present, although I do not have an SX Pure compatible atomiser to try this out with.

Reverse battery polarity protection is listed in the specifications for the IPV400, however I wouldn’t recommend inserting the batteries the wrong way. There’s actually a warning inside the box saying not to reverse polarize the batteries, as this will damage your unit, and there are a few reports online of consumers IPV400 units auto firing when the batteries have been inserted the wrong way. It’s best to take the time and check that you do insert your batteries correctly.

Battery life is great, the IPV400 takes two 18650 batteries and as long as you are vaping at pretty moderate wattage, you’ll get well over a day’s use. Even vaping at high power, you do get pretty admirable battery life, and the batteries are easily accessed through the sliding battery door cover at the base should you need to swap them out for fresh ones.

Conclusion

Although the IPV400 is a slight let down in the looks department, it makes up for it with its overall performance, albeit with a few flaws such as the apparent lack of reverse battery polarity protection and stainless steel temperature control wire compatibility with 304 grade stainless steel rather than the more widely used 316 stainless steel, although that can be remedied with the implementation of custom TCR input.

In summary, the IPV400 is a device that will offer reliable performance, however the looks and less than perfect build quality may turn some users off. It’s available at a very competitive price from many retailers, so if you aren’t fussed on looks and are looking for a device that offers consistent performance, this may well appeal to you.
