Using the Joyetech eVic
Most of the interesting things with the eVic (available at Panda eCigs) start with the menu system. The menu is controlled via the ring under the display. Small arrows appear indicating which way the menu (or power) will scroll when it’s turned. Turn left to move down the menu and right to go up.
To be honest, I find that counterintuitive. For some reason, the muscle memory in my brain is wired to think that turning a ring left (clockwise) should move a menu up instead of down. I have to make a concentrated effort to turn the thing the right way.
Now that I got that off my chest, let’s talk about the display and menus. First off is the main display. To access this display, just turn the wheel in either direction. A screen comes up showing the current puff count, the number of estimated puffs remaining on the battery charge. Battery life is also displayed via a graph and a percentage, so you shouldn’t have an excuse for not realizing you should plug it in for a charge.
Don’t think you can just ignore the battery life and just plug it in and still vape like a pass-through. Once the eVic is plugged into USB, you can no longer actually use it until the connector is removed.
Underneath the battery and puff displays is the current voltage or wattage setting. The power can be adjusted simply by turning the dial in the desired direction. Each turn is one increment.
Not to keep hitting on the not-quite-what-I-expected thing, but you’d think holding the wheel in one direction would allow it to scroll through the settings. Nope. Fortunately firmware version 1.1 introduced a new feature where if you move the wheel quickly 3 times in a row, it will keep scrolling until you move the wheel in the other direction. It’s not perfect, but it’s better than moving from 7 to 9 watts .1 watt at a time.
The range at which you can adjust the wattage will be limited based on what resistance cartomizer you have installed. The Joye added a feature where the eVic will calculate the minimum and maximum power it can deliver and limit your settings to that. Voltage seems to take a back seat as the eVic will make the whole voltage range available and simply deliver a lower voltage if it can’t handle the amp load.
Another nice thing is there’s no need to wait for the display to time out after changing the wattage. You can hit the fire button at any time and it will activate the power. Once you let go of the button, the display shows how long you pressed it. Kind of an unnecessary feature, but fun. I average around 4 seconds per puff.
Because the button is used to select menu items, you can’t do the same thing while in the menu system. To access the menu system, press the fire button 5 times rapidly. From there you’ll have access to the settings and information on the device. The enhanced display and wheel design means that submenus are all over the place. Sometimes finding what you’re looking for isn’t the easiest thing in the world.
For example, switching from voltage to wattage operation requires going into the “vapor set” menu then selecting “switch” from there you can pick your mode of operation. Fortunately, the only other menu with a big submenu is the “device” menu which mostly displays information about the device.
You can also adjust other settings that aren’t all that common. The length of time the main screen stays on can be adjusted. More importantly, the standby can be adjusted. This is the amount of time that passes without use before the eVic shuts off. The default is 15 minutes, and you can set it up to an hour. There’s no way to disable the feature. When it does shut off on you, click the fire button 5 times to turn it back on.
Additional settings can also be adjusted using the MVR software.
Before I wrap up this now epically long eVic review, it’s time to talk about performance. The eVic is a stable but moderate device. Power output is correct when using variable voltage, generally within .1v of the set voltage. Variable wattage, however, seems to be a little low. I found the output voltage to be low by about .5v in some cases, a fairly significant drop.
The other performance problem I ran into is pretty much standard for single battery devices these days. Amperage appears to be limited to around 2.5a. A 1.5 ohm dual coil maxes out a hair short of 4v. This is an incremental improvement over some variable voltage devices which step dual coils down to 3.5 or 3.7v.
One thing to keep in mind is that the eVic can be updated via software. That means some of the issues I talked about could be fixed in the future. I’m not sure that the amperage can be adjusted since that very well could be a limitation of the physical hardware.
What I’d really be interested in seeing in the future is for someone to crack the firmware allowing for community built firmware. Now that would be interesting.
Too Long; Didn’t Read
The Joytech eVic is a significant change in e-cigarette technology. If you’ve ever bought a device only to have version 2 come out a week later, you can see where a software upgradable vaporizer is a really good idea. There are a few shortcomings to the eVic, but they are fairly minor and some may be fixed in software at some point. Despite some of the negatives, the eVic remains a very compelling choice and a solid device. Grab one at Panda eCigs at a great price.
