Our good buddy Joe Cloudie sent me an IPV D2 from Pioneer 4 You about a month a half ago along with a care packet for my mother in law. We’ve talked about it a few time on the podcast, and after some extensive use and testing, can finally do a full write up review.
The IPV D2 is what I refer to as rounded box mod. It’s not a tube, not a box, but a hybrid of the two. This makes it more comfortable in my opinion than a true box, but still prefer a tube. It’s made from high quality aluminum (not my words, P4Y’s. My guess it’s a 3xxx series, but can’t say for certain), with stainless steel 510 connection, and a brass spring loaded positive pin. Has a U shaped battery door that is held in place with ball bearings, and comes with a silicon cover as you can see from the pic above. I have a feeling the cover will become more important as time goes on as the door is already easier to remove now then it was when I first started using it. The D2 is powered by the SX130 chipset from YiHi, which is able to do up 75W/8V on a single 18650 high drain cell. At 3″ tall this is a very compact mod. Also features a charging port, but we’ll get into that later. Enough of the specs, let get into the real world numbers.
Accuracy- Was not surprised at how on point this chipset is. YiHi has been putting out some really great boards over the past year plus, and the SX130 is no different. The biggest issues were at low wattage. 7W was 8.1-8.5W on a build sub 0.5Ω. On higher resistance no such issue, and was accurate across the board afterwards within .03W. Even the Evolv boards can be off within .01W of their setting, it’s a very negligible amount. I have yet to meet a vapor who can tell the difference between 21.31, 21.33, and 21.3W. It’s Ohm reader is also pretty accurate. On my fluke the dual coil I’m running in the Aqua 2 from the pic above is at 0.62Ω, getting ranges from 0.6-o.64Ω. Using it on my DNA30 device see very similar numbers 0.59-0.63Ω to be exact. It can indeed hit 75W on low builds. You’re capped at 8V or 25A, which ever comes first. Keep that in mind.
Battery performance- I’m not a fan of the cell phone style battery indicator. It really means nothing to the user who tracks when they charge their cells to get maximum lifespan. As usual pulled the battery and checked it after every significant drop in battery power. At roughly 3/4 the battery is at ~3.91V off load (OF), 1/2 ~3.73V OF, 1/4 ~3.48V OF, when it auto cut off the battery read at 3.31V OF. That was at 10, 20, 30, and 40W. At 50W+ the battery stopped functioning at 3.46V. Was using a pair of Sony VCT4’s and AW 1600Mah IMR cells for the testing. The D2 features a USB charging port, would not suggest using it. Did a few tests with it, batteries would end up either being over charged (4.31V) or significantly undercharged (3.88V). It’s better to pull it, use a quality charger, and put a fresh battery in.
Temperature Control- The SX130 chipset is limited to titanium and nickle wire if you so chose to use this feature. I’m not a big fan of it, and in fact waiting on a buddy to send me 6″ of nickle was the big delay on this write up. It works as well as any other temp control device I’ve used in the past…. Which means it doesn’t. Even though I had it set to 350°F, using an infrared thermometer would see temps as high as 461°F and as low as 244°F. Until we have a device with a temperature sensor lead going to the atomizer, not just an algorithm guessing the parameters, it will just be a selling gimmick and nothing more. This doesn’t just apply to the D2, but every single temp control mod on the market.
Durability- Still can’t say the long term, but can say in the short term I’ve dropped the D2 multiple times without any real issue. The negative contact over tab over the spring got a little bent on one causing it not to make good contact anymore on smaller cells, simply pulled it back into place. No scratches or dings to speak of. The only item as I alluded to earlier is the battery door using ball bearings to hold it in place. They have already caused some wear on the door itself, and am quite sure as time goes by they will fail to hold the door in place completely. This is where the silicone cover comes quite in handy. It’s a pain in the butt to put on at first, but after 20-30 times of taking it on and off loosens up.
Final thoughts- Despite the few faults, you’ll be hard pressed to find a mod with as many features as the D2 at its price point. You can find them regularly for $40 on-line, usually around $50-60 at a B&M. 75W, small form factor, accurate chipset (in wattage mode), good build quality, and a spring loaded 510. There are mods six times the price on the market that can’t claim the same. Vapor Reporter Approved.
