IPV4 S by Pioneer4You Review

Welcome to my latest review. This time it’s of the IPV4-s which has been created by the wonderful folks at Pioneer4U.

Before I get into the whole review I want to make sure everyone knows that although I own the IPV4 and the 4s I will not be reviewing the IPV4 as there isn’t enough difference between the two units to warrant a separate review of both models.


So I bought the IPV4 a few months back in the silver colour and I was running it with my silver Turbo RDA manufactured by Tobecco. I was so impressed with the performance of the MK1 IPV4 that I decided to buy the black version too so I could use my Black Turbo RDA. As a lot of you who know me personally will already know, I am a sucker for my Mod/Tank/RDA having to be the same colour as their counterpart… Maybe it’s a bit of my OCD kicking in but HI-HO, least I’m not shooting up schools in America!
Back in January I purchased the IPV3 device which was capable of firing up to 150W… however this was very short lived as the IPV3 device was dangerously inaccurate when it was reading the resistance of the coils on my RDA. So much so that when I built at my typical 0.2Ohms and hoofed a lung full there were times my build would actually go on fire! The resistance that should have been 0.2Ohms suddenly was read at over 1.0Ohms which meant that the chip would send more voltage than was needed to the coils and then they would set the cotton on fire. If I’m honest, this put me off the IPV range for a while as I completely lost trust in Pioneer4U as a company for allowing such a huge fault to go into mass production.

This phobia of the IPV range was rather short lived though as I bought the IPV Mini2 (Review to come shortly) which fired up to 70W and was able to read down to 0.2Ohms.


I then heard all the hype about the IPV4 100W Box mod which I eagerly awaited to get my hands on. FINALLY my IPV4 arrived and I had my spare 18650 batteries fully charged and ready to go along with my Turbo RDA freshly built and soaked in some delicious Red Vape Strawberry Fusion (Review also to come soon). I popped my batteries in and screwed on my RDA and BOOM I was ready to chuck some serious clouds! I mentioned earlier that my typical RDA build was 0.2Ohms…. This is achieved by using 22AWG 6 wraps dual coil and the IPV4 read this as 0.28Ohms smile emoticon I set my wattage to the desired 60W and fired it up! Wow it was unbelievable! There was absolutely no ramp-up time and no annoying “clicking” sound that the shitstick 50W produces. The vapour production was exquisite with full flavour and consistent power output at the 60W. I set my 5 memory settings to 50,60,70,85 and 100 Watts and each time I selected the memory setting I wanted, The IPV4 put out that exact amount of power.

I was so impressed with the IPV4 that I decided to buy the IPV4-s model which is what I am currently vaping on as I type up this review. I’m using the Troll RDA by Wotofo with my above mentioned build at 50W. I know that the IPV4 models may not be to everyones taste for a number of reasons, but for me they are designed perfectly with stability, reliability and power in mind.


The IPV4-s has nearly the exact same body as the standard IPV4 models with one or two minor cosmetic changes. On the Mk1 IPV4 devices there was an annoying charging port near the 510 connection which served no purpose as you could not connect the IPV4 to a power supply without it going on fire… In addition to this, the “charge port” had a few rumoured issues where the internal wiring would drop down onto the internal battery contacts and cause a short within the device which again allegedly caused fires. On the new models (4-s and above) Pioneer4U have rectified these issues by plugging the charge port and creating a brand new battery cover which appears to be a little more durable than previously in production. This new battery cover also has the charging port hole completely removed so unless you are like myself and have the pleasure of owning both variants of the IPV4 you wouldn’t know there was ever a charge port there in the first place.

The IPV4-s has an updated chip set on-board too which now can fire up to 120W rather than the previous 100W on the Mk1 model. When I run the two models side by side at my usual 50-60W there is a bit of a difference in power output between the pair. I find that the IPV4-s takes a split second longer to produce vapour and the vapour at 60W feels like that of 50W on the Mk1 model. The screens on the devices are identical and they both read my builds at 0.28Ohms, one thing I have to point out but as far as I am aware Pioneer4U know of this issue and have resolved it before now; is the brightness of the screen on the Mk1 silver edition. The screen is absolutely impossible to read on the Mk1 Silver due to a mirrored screen design which is 50/50 indoors but outside its terrible. On their black models however, they have fixed this issue and the screen is crystal clear.


The IPV4-s also has the capability of reading and firing titanium wire builds. I have to be honest though, I’ve not attempted titanium builds yet so I cannot say if it works or not on the 4-s but there is a function there to select titanium builds for temperature control anyhow smile emoticon
The retail packaging of the IPV4-s is identical to that of the Mk1 IPV4 device with the addition of a sticker to say that it is the upgraded 4s version. Inside you will find your quality control approval card, your mod and underneath a Micro USB cable which is NOT FOR CHARGING. The Micro USB is for software updates and diagnostics on the P4U website directly.


So, would I buy this mod again if I lost it somewhere? It has to be said that although I already own 2 of the Mk1 IPV4 devices and the IPV4-s I would for sure buy another IPV4-s even if they brought it out in silver! I’ve never been more impressed with any mod before… The IPV devices tick all the boxes for me when it comes to stability, power and battery life. In series mode at 60W on my 0.28Ohm build using 2x Sony VTC4 batteries I would get nearly 20 hours of vaping pleasure. The only slightly irritating thing about the battery is the diagram on the screen shows the battery power to be around a quarter when it cuts off but the voltage left in the battery is 3.4V from 4.2V.
