Reviewer comments on business characteristics
The Chinese manufacturer Pioneer for You has already made some grinds of its box IPV, for the vape say, classic. With the 4S-2, we move to the upper template. The first version offered 100 W since June 2015, it was switched to 120 W with the 4 temperature control months later thanks to the upgrade of the Yihi SX330-V4S chipset to the SN version, more in phase with the news of the evolution of the box electros. The fans of power vaping with good grip (the model in question is not a mini) will be able to indulge in their passions fogged without restraint and safely.
Its price remains correct, given the performance announced, the good overall quality of the object, and the reputation of serious that has acquired the brand over time. Let's take a look at this latest version of IPV 4S.

Reviewer's comments on physical characteristics and perceived quality
This box has a thickness at the connector of 23 mm, while its maximum thickness is 26 mm, at the non-slip coating of the hood housing the battery housing. The latter is rigid PMMA and is not in my opinion the best option for solidity. 4 balls positioned on the box, ensure the maintenance of the hood once closed (in the right direction).
The top cap is oddly grooved, because to look at it, they can not ensure the air supply of an ato of 22mm from below, and the possible leakage of juice will also have trouble to find their way in their direction. Fortunately, the positive brass pin is adjustable (no screws) and the connector is stainless steel, it compensates a little strangeness mentioned above.
The battery compartment is equipped with a ribbon for extraction and brass contacts mounted on spring, it allows (with difficulty) the use of button top battery (positive pole protruding).
Below you will find the micro-USB charging connector and two rows of five vents allowing the possible degassing of the batteries.
The functional part consists of a rather small Oled screen, 0,96 '' (the proportions of the box would have supported a larger screen), and three buttons: a 10mm diameter switch and 2 settings (+ and -) of 5mm of metal (aluminum) diameter barely protruding in the width of the box, it is appreciable because less subject to maladjustments or involuntary firing.
With no less than 275 g once equipped with its 2 batteries, the IPV 4S-2, without being the heaviest box of this type, still weighs its weight and will not suit everyone. Her measurements are also quite impressive, comparable to those of her colleague the IPV 3 LI. I doubt that women are seduced by these characteristics. For us men, the object is ergonomic and well studied and our paws will have no trouble understanding it, the specific function of such a powerful material being to indulge in the joys of cloud chasing, we will consider its dimensions as a secondary aspect of no real importance.

Reviewer's comments on functional features
The functional characteristics are those of the IPV series boxes, equipped with the SX chipset, with a new option for the latter: the conversion of power into joules for the TC (temperature control) function which operates in the presence of nickel or nickel resistors. Titanium.
Here are the specifics of IPV 4S-2:
- chipset: YiHi SX330-V4SN (YIHICIGAR) Site page for firmware upgrade: here
- Output powers: 10W - 120W in 0,1W increments
- Output voltages: 1V mini - 7V maxi
- Resistances tolerated: 0,1 to 3,0 ohms in VW mode
- Resistances tolerated: 0,05 to 3,0 ohms in TC mode
- Variable Temperature: 5 to 50 Joules (Nickel Ni 200 Resistor) or 5 to 100 Joules (Titanium Resistors), 100 ° C (212 ° F) to 300 ° C (572 ° F)
- 2 batteries mounted in series (not supplied) with high peak and continuous discharge capacity (25A mini, IMR "High Drain", flat top highly recommended)
Safety and functionalities:
- Protections against over-discharges, short circuit and excessive temperature of the on-board electronics. Reverse polarity is also taken into account and protected.
The IPV4-S can be recharged via the micro-USB cord (supplied) and an AC adapter (not supplied) but it is preferable to opt for a good dedicated charger and to reserve the pair of batteries used for the box only , to buy them for it and to recharge them together.
To put the IPV4-S into operation, access the power or temperature control mode and the various settings, all you have to do is press the switch 5 times. The navigation in the different menus is very intuitive and quite simple (always with the switch). You have 5 storable settings: M1 to M5. Adjustments and settings of any function are made with the + and - buttons.

Reviewer's comments on conditioning
Your material will arrive in a cardboard box (141 x 90 x 52 mm); the box appears on the surface in a semi-rigid foam, well protected from shocks. Once removed, on the floor below is a cardboard partition which, once out, gives access to a manual (in English), a USB / micro USB cable for recharging on a PC, as well as a quality control label and finally, a warning card on the quality of the batteries you will need to use.
A clean package, adapted to the material, quite correct in this price range.

Reviewer's comments on the use of the product
In use, this box is very responsive, and not only regarding the response of the settings buttons. I mean what she's supposed to send to your ato. Whatever the power requested, the IPV4 responds to the quarter turn, we immediately understand the interest it will arouse in lovers of the vape in ULR (ultra low resistance). For powers below 50W, in addition to these efficiency characteristics, the presence of a pair of batteries will help to prolong the pleasure of a stable vape, without peaks or failure. The regulation provided by this chipset is precise, linear and it is itself energy efficient.
I have not found a command to lock the settings, at this stage of the test I do not know if there is one. Anyway, here is a box that provides exactly the vape that we ask for in complete safety. Its handling is pleasant, but it is desirable not to keep it in your pockets during breaks. A bag will allow you to store a 2nd pair of batteries, one or 2 vials of juice and the essential material to remake a coil, you will be ready to vape on the go and you will preserve this fragile object, if we compare it to a good old one mech in stainless steel.

The mood ticket of the reviewer
Pioneer 4 You is in a good position in the race to the controlled power, this IPV4S-2 is at the level of its competitors. It is, moreover, financially affordable which improves its attractiveness.
Intended for an informed public, it will probably be adopted by a large panel of vapers as its regulation is constant regardless of the power required. If, in addition, it turns out that it is as reliable in time, we can think that its future is assured. The designers of the chipset that the team will probably offer a temperature control all materials as already done Joyetech, monitor the site of the manufacturer. If such an upgrade is proposed, you will have in your hands a little gem to vaper safely with the range of atomizers and resistors available on the market.
In the meantime, you have a lot of fun with this latest version of the 4 LPI series.
See you soon
