The original Ari set your voltage with a twist knob on the base, and you set it by feel. The Ari 2.0 replaces that with an OLED screen and plus and minus buttons, so you can see the number and move it in tenths of a volt. That is the whole story of this update, and it is a good one.

650mAh in a 14mm pen body, which is enough for most people to get through a couple of days. Five colours.

Key Features

An OLED Screen, New To The Ari Line

This is the first Ari battery with a display. It shows your voltage, battery level and a running puff count, which resets itself once it reaches 9,999. No more guessing where the knob is pointing or how much charge is left.

Precision Voltage From 1.8V To 4.2V

Adjust in 0.1V steps with the plus and minus buttons. Different oils behave very differently, and being able to set an exact number rather than a rough position is what lets you find the right setting for each one and come back to it.

650mAh In A Slim Pen Body

At 14mm across and 94mm long this is still a pen, but 650mAh is generous for the size. A full charge takes around an hour and twelve minutes over USB-C, and the port is on the side so it stands up while it charges.

Ten Second Preheat

A 1.8V preheat runs for ten seconds and loosens thicker oils before you draw. It is the standard fix for a cartridge that has been sitting somewhere cold, and it makes the first pull as good as the ones that follow.

Proper Protection Built In

Short circuit protection, low resistance protection for cartridges below 0.8Ω, a 15 second cut-off on any single draw and an automatic shut-off after an hour idle. None of it is glamorous, and all of it matters on something that lives in a pocket.

How To Use The Yocan Ari 2.0

1. Screw your 510 cartridge into the top, turning clockwise until snug. Do not overtighten.
2. Click the power button five times to switch the battery on.
3. Set your voltage with the plus and minus buttons. Around 2.8V is a sensible starting point.
4. Hold the button and draw. Double-click first to run a ten second preheat if your oil is thick.

Cleaning And Maintenance

Clean the 510 connection with a cotton bud and a little isopropyl alcohol whenever oil works its way into the thread, and let it dry completely before refitting a cartridge. Wipe the body with a dry cloth only. If the screen stops reading your cartridge correctly, a dirty connection is almost always the reason.

Who Is The Yocan Ari 2.0 For?

• You want to set an exact voltage rather than approximate it.
• You would rather have a screen than a twist knob and guesswork.
• You want more capacity than a typical slim pen offers.
• You find a puff counter genuinely useful for pacing.

Who Might Want To Look Elsewhere?

Nothing but the battery is in the box, so you will need to supply a USB-C cable. Cartridges below 0.8Ω will not fire, which rules out some low resistance carts. And if you want a top-mounted dial as well as buttons, the Yocan Lux 2.0 has both, though it carries a smaller 400mAh cell.

The Final Word

The Ari 2.0 takes a decent pen battery and gives it the one thing it was missing, which is a screen and the precision that comes with it. Good capacity for the size, sensible protections and a price that does not ask much. A straightforward recommendation for anyone who wants control without carrying a box mod.
