It looks like Innokin is continuing their line of iTaste VV devices with the new iTaste VV 4. This new version brings some improvements over the previous version. It can fire down to 0.8ohms, has a spring loaded 510 pin, now has a 1000mah battery, and the best of all is the much improved screen. All your information is right there on one screen. You have watts, volts, resistance, and battery level. This is much better than the V3 where you had to hold down the up and down buttons, then wait for the puff counter to go away just to see your resistance.
I had an iTaste VV 3 and used it as my primary device for quite some time. It was a great device and the iTaste VV 4 improves on most aspects of that device.
- Variable Voltage: voltage can be adjusted from 3.0 – 6.0 volts in .1 volt increments
- Variable Wattage: Wattage can be adjusted from 6.0 – 15.0 watts in .5 watt increments
- Ohms meter, battery level, puff counter
- Short circuit/atomizer protection (0.8ohm)
- 10-Second Cutoff: If the button is held down for 10 seconds or longer, the iTaste VV4 will stop firing until the button is released and pressed again
- Over-Discharge protection: The iTaste VV4-M monitors the battery voltage and will automatically turn off when the battery is discharged
- Low battery warning: The red LED and battery bar will continue blinking when the battery capacity is lower than 3.3V
- The LED lights will show green, yellow or red to indicate full battery life, half capacity or charging needed
- Superior battery life: The iTaste VV4-M e-cigarette features a built-in 1000 mAh polymer Li-Ion rechargeable battery
- ON/OFF battery switch: Quickly clicking three times will power the device on or off
- Passthrough: The iTaste VV4 is charged through a Micro USB Port. You can recharge it with any standard MicroUSB cable. It can also work as a pass-through device for simultaneous vaping and charging
- Display information: The bright display shows resistance (ohms), voltage, wattage, battery level
- Standby current: 50uA
- Maximum output current: 4.0A
- Micro-USB Charging: DC 5.0V/500mA

Here’s a review of the Innokin iTaste VV 4 by IndoorSmokers:

Your description of the iTaste VV4 states that firing down to 0.8 ohms is an improvement over the iTaste VV 3.0, but the VV 3.0 will also fire coils down to 0.8 ohms. Granted, it is pretty pointless, as the VV 3.0 will only fire it at 2.8 volts to keep it within maximum limit for current (3.5 amps). Regardless of what you set the voltage to (3.3 – 5.0 volts) it will fire your 0.8 ohm coil at 2.8 volts (verified with a multimeter). This works out to 9.8 watts.
With the slightly higher 4.0 amp limit on the VV4, it can only fire a 0.8 ohm coil at 3.2 volts or less, which works out to 12.8 watts. The means that in VV mode with a 0.8 ohm coil, if you set the voltage to anywhere from 3.2 volts up to 6.0 volts, you will only get 3.2 volts out of it. Over in VW mode with a 0.8 ohm coil, you will only get 12.8 watts even if it is set to 13.0 watts or higher.
To get the full range of available voltage from the VV4 (3.0 – 6.0 volts), you need a coil with a resistance of 1.5 ohms or higher. With a 1.5 ohm coil, this will actually give you 24.0 watts at 6.0 volts and still be within the maximum current rating of 4.0 amps, a huge boost over the VW mode’s maximum power setting of 15.0 watts. In VW mode, the lowest resistance coil that it can fire at the 15.0 watt maximum is 0.94 ohms, which it will do so at 3.75 volts when set to 15.0 watts.
Basically, if you want the full range of wattage to be usable in VW mode on the iTaste VV4, the lowest resistance you can use is 0.94 ohms. If you want the full range of voltage in VV mode (and be able to squeeze out an extra 9.0 watts at 6.0 volts), you need a 1.5 ohm coil. You can of course go higher than 1.5 ohms, although doing so will reduce the “extra” available wattage. Once you get up to a 2.4 ohm coil, firing it at 6.0 volts will match the VW mode’s maximum setting of 15.0 watts.
Correspondingly, on the iTaste VV 3.0, you can coax out an extra 1.5 watts (bringing you up to 12.5 watts instead of the 11.0 watt maximum in VW mode) if you use a 1.43 ohm coil and set it to 5.0 volts.
Another quirk, at least with the iTaste VV 3.0, is that while it can fire a coil down to 0.8 ohms, the ohmmeter will actually measure down to 0.4 ohms. Anything lower than 0.4 ohms will read as 0.0 ohms. I’m not sure if the same goes for the VV4, but a quick test should allow you to determine the limits of its ohmmeter. I suspect it will be the same as on the VV 3.0, but would be interested in knowing for sure, so if you could perform that test I’d appreciate it.
Thanks so much for pointing out bargains on vaping gear! I’m looking to buy at 50+ watt APV without spending more than $100 or so, and found several on your site that fit the bill. Ever since about 2 years ago when I switched over to mechanical mods, and using thicker wire and sub-ohm coils for high-wattage vaping, I haven’t kept up with what was available in the VV/VW arena. I’m excited to try high-wattage vaping with thinner wire and higher resistance builds, since it offers a number of advantages compared to the “old-fashioned” way of sub-ohm builds on unregulated mods. But the sheer number of models available now really surprised me, and your site has been most helpful. I’m leaning forwards an authentic iPV2S.
This will be some good info for anyone looking into this device. Thanks.
I thought my vv4 was faulty at first cause of this very same reason.
My vv3 fires up 0.8 coils with no issues, so when I used the coil with my vv4 and it didnt fire up, just kept on blinking, I thought it was a faulty product.
Its not that big of an issue for me though, cause I’m just going to use up my 0.8 coils on my vv3 and just purchase 1.5 coils from now on to use with the vv4.
I really am fond of the itaste pens, they’re my daily vapes.
I hardly use any of my other mods unless I’m showing them to friends or family.
I think the vv4 is definitley a step up from the vv3, especially the battery size and lcd display, it feels better made as well, doesnt have the rattling buttons like the vv3.
Thank you for this message, it certainly helped me and would help others make an informed choice about whether or not to purchase this product.
