The eVic VTC Mini is one of the easiest mini mods I’ve used. Many of the functions are pretty conventional. For instance, five clicks of the fire button turns it on and off; three clicks takes you to the menu to change change modes. You have a choice to use the bypass mode, which basically turns it into a mech mod, but we don’t recommend using this mode unless you know exactly what you’re doing. You’ve also got variable wattage, TCR or three temperature control modes – nickel, titanium or SS316 stainless steel. You use the up button to scroll through the modes, then hit fire once to select the one you want. Not overly complicated at all. TCR is a new mode that JoyeTech have come up with, and it’s a useful bit of future proofing. It stands for Temperature Coefficient of Resistance, which is a characteristic of the different metals used to make TC coils. TC works by the mod sensing changes in coil resistance, which that lets it work out the temperature.You can read more about how temperature control works here. The first TC mods used nickel coils; when titanium, then steel, ones appeared those devices couldn’t use them because the metals have a different TCR. If a new coil material comes out you can use it on the VTC Mini even though it doesn’t have a mode set up for it. All you need to do is find out the TCR, which you can get from here, and programme it into the device. You can store three different values; after that’s set up you can adjust the temperature as normal. There are a couple of other button functions. Holding the fire and down buttons together puts the VTC Mini in stealth mode, turning off the screen. And you can hold the up and down together to lock the mod, so you won’t accidentally knock your settings off. In TC mode you can set the maximum initial wattage; press fire three times, then the down button. The displayed wattage will start to flash, and can be adjusted with the up button. As usual, press fire to confirm the setting. I’m not sure why you’d need to do this, but you can if you want to. All the usual protections are there – reverse polarity, short circuit, excess temperature and low voltage. On top of all of this you can even update the firmware. It basically has all the features you’d expect in a high end mod, without costing all that much, which is why it’s one of my favourite mini mods.
I have no complaints with the VTC Mini’s screen. It’s very large, clear and bright – one of the best I’ve seen on a mod. It also isn’t too deeply recessed inside the case, so it’s easy to see from a slight angle as well. On some devices you have to look pretty much straight on or bits of the screen are hidden by the casing; that’s not a problem here. How the screen is laid out depends on what firmware version you have (it can be updated from the JoyeTech website), and some versions are easier to read than others. There’s certainly plenty of information available. The text appears horizontally, so the screen doesn’t need to be flipped. It has enough space to show the mode the device is in, puff count and duration as well as the usual resistance, voltage, power and temperature. I’d be really happy if all my mods had a display this good.
The VTC Mini is powered by a single removable 18650 battery, which you’ll need to buy separately; you’ll need to get one that can deliver at least 25 amps of continuous current. Fitting the battery is easy; just pull off the magnetic cover to open the compartment, then pop it in. There are large, clear markings to show which way up it goes (and reverse polarity protection to avoid frying anything if you still get it wrong). You can charge it through the micro USB port on the front of the mod, and it has pass-through charging so you can keep using it while charging. However, I would recommend getting an external charger, which will charge your 18650’s faster and safer. It’s also worth having a spare battery so you always have a charged battery to use.
This is a great little device that fully deserves its popularity. It looks good, only let down slightly by the plastic buttons. It feels very well made, and people who’ve dropped them report that they survive pretty well. It has all the features you’d want and the TCR mode means it should be able to use practically any new TC coil material that comes out. JoyeTech have come up with a real winner here, and it doesn’t cost a fortune either. Unless you’re looking for a 250W mega cloud machine this is one of the best options out there.
