YLL Induction Heater 3.0 Review

Background

Hi everyone, today I’m reviewing the all-new YLL 3.0 induction heater. I’ve been using it for around three months now with all my battery-free devices like the Tempest 2 and Tornado, which I have separate reviews of. It basically retired my previous induction heater—the Wand.

The YLL 3.0 is available from VGEAR.COM for $120, and coupon code YLL20 will save you 20% for a final price of $95. Amazing value imo. 

Why Induction? 

Battery-free thermal extraction devices (like the Tempest or the Dynavap), by their design, do not contain an internal heat source. Heat must be applied externally to the metal cap to reach the necessary vaporization temperature. The two main ways to achieve this are using a butane torch or an induction heater.

While torches certainly have their place, I'm personally not a fan of the open flame, the need to constantly refill with butane, or the variability in heating technique. For consistency, precision, and ease of use, I opt for induction heating basically 100% of the time.

Design

The YLL 3.0 has a boxy shape, with the interface on top, the chamber (which I’ll talk about in a minute), and a small magnet to help keep devices upright.

The back has a magnetic cover, with space for two 21700 batteries, which are not included in the kit, by the way. I got mine on Amazon; I’ll link them below.

The chamber

Then, the chamber has a removable glass cylinder. This little piece at the bottom is adjustable, so you can move it up or down to work with your specific device.

This is a huge feature for dialing in your specific device and preference, whether you want to heat closer to the tip for better flavor or deeper for maximum extraction. I’ve found that for both the Tempest 2 and Tornado, keeping the piece at the bottom provides the perfect heat profile.

Before I place the cylinder back, we can see the induction coil here. This is the copper coil that performs the magic. When a high-frequency alternating current passes through this coil, it generates a powerful, rapidly oscillating magnetic field.

How does it work?

When you place a compatible ferromagnetic material (like the stainless steel or titanium cap of your device) into the center of this changing field, the field induces swirling eddy currents directly in the metal cap itself. These currents encounter electrical resistance in the metal, which rapidly generates heat via Joule heating.

This is why induction heating is so incredibly efficient and precise: the heat is generated in the cap, not by the induction heater's coil or the surrounding air. The glass cylinder remains relatively cool, only getting warm from the hot metal inserted inside. There is virtually no wasted heat, making for faster, more consistent heating.

Interface

Three clicks to toggle on and off, and once turned on, it’s ready to go. All I need to do is insert the cap. The heater detects that and starts applying heat, plus there is a countdown to let me know when the heating process is finished.

The big temperature lie

Now, there is something you should know about induction heaters. Many of them, including The Wand, display a “temperature setting.” This number is nothing but a pre-set timer; a higher displayed temperature simply corresponds to more seconds of heating time. There is no temperature probe inside the chamber measuring the heat of your cap. It's a marketing gimmick, and frankly, I can’t stand it.

The YLL 3.0, thankfully, avoids this fake temperature display. Instead, it shows the proper, accurate information: Watts and Seconds.

The seconds can be adjusted with the up and down buttons, and the watts can be adjusted by double-clicking the center button.

Best settings 

For both the Tempest 2 and the Tornado, I keep mine at 95 watts and 30 seconds. Once you dial it in perfectly for your specific device, there is very little messing around with settings. Just pop it in, and that’s about it.

Bottom line

Bottom line, the YLL 3.0 is two levels above the Wand. It looks better, it doesn’t wobble around when placed on the desk, the settings show the correct info and not a made-up temperature, plus it has the magnet, which is super helpful. It easily wins in all categories and is the best induction heater to use with any battery free vaporizer.
