Yocan Flat 2.0 Plus Dab Pen Battery

Buy the Yocan Flat 2.0 Plus Dab Pen Battery UK

The Flat 2.0 Plus is the largest of the three Flat 2.0 batteries, and the two things it changes are the two that matter. A 900mAh cell gives you roughly forty per cent more capacity than the standard Flat 2.0, and a wider 17mm body seats larger cartridges flush against the frame rather than leaving them perched on top.

Everything else that made the Flat series popular stays exactly as it was: the slim, angular profile, the OLED display and voltage adjustable to a tenth of a volt. Available in six colours.

Key Features

900mAh, The Longest-Lasting Flat 2.0

Where the standard Flat 2.0 carries 650mAh and the Mini 400mAh, the Plus runs to 900mAh. That is the difference between charging every other day and charging most days, and it comes at the cost of three millimetres in width. A full charge takes around an hour and twenty minutes over USB-C.

A Wider Body For Wider Cartridges

At 17 x 17mm the Plus is three millimetres broader than the standard Flat 2.0, which is enough for larger cartridges to sit flush rather than overhanging the edges. If you have ever found a cart looked awkward on a slim battery, this is the fix.

Precision Voltage From 1.8V To 4.2V

Adjust in 0.1V steps using the plus and minus buttons. Lower voltages give a cooler, more flavour-led draw and are kinder to your cartridge; higher voltages produce thicker, warmer vapour. It is proper control rather than three crude settings, and it makes a real difference across different oils.

OLED Display With Puff Counter

The screen shows voltage, battery level and a running puff count. There is a ten-second preheat at 1.8V on a double click, which is the easy fix for a thick oil or a cold cartridge that will not draw properly.

Aluminium Alloy Build

The flat, angular aluminium body slides into a pocket like a card rather than rolling around like a tube. It takes a knock well and feels considerably more solid than the plastic-shelled batteries it competes with. USB-C charges from the side, so it will stand up while it charges.

How To Use The Yocan Flat 2.0 Plus

1. Screw your 510 cartridge into the top of the battery, turning clockwise until snug. Do not overtighten.
2. Click the power button five times to switch the device 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 to run a ten-second preheat if your oil is thick or cold.

Cleaning And Maintenance

Wipe the 510 connection with a cotton bud and a little isopropyl alcohol whenever oil finds its way down there, and let it dry fully before refitting a cartridge. A clean connection is the most common fix for a battery that has stopped reading a cartridge properly.

Who Is The Yocan Flat 2.0 Plus For?

• You want the longest-running battery in the Flat 2.0 series.
• You use larger cartridges and want them to sit flush with the body.
• You value precision voltage control and a clear display.
• You want something genuinely pocketable that does not roll off a table.

Who Might Want To Look Elsewhere?

If maximum discretion matters more than runtime, the narrower standard Flat 2.0 or the Flat 2.0 Mini will disappear more completely into a pocket. This is a 510 thread battery for oil cartridges, so if you are looking for a dry herb device you want the Xmax or Arizer ranges instead.
