YLL Induction Heater 3.0

The YLL 3.0 replaces the butane torch for any battery-free vaporizer that has a metal cap: it heats a Tempest 2 or a DynaVap indoors, silently, with no flame and no technique to master. Reviewers single out the control: you set the exact power and time, and the device repeats those settings every session.

A torch heats a cap from outside, one spot at a time, and no two heat-ups are identical. Induction generates the heat inside the metal itself, evenly and all around. That is why owners consistently describe a more even roast of the herb and more sessions from the same load.

There is no trigger to hold. The chamber senses the device the moment you insert it and starts the cycle. Lift it out and heating stops. A copper coil under the glass creates a fast-switching magnetic field. The metal cap develops currents inside itself, and those currents are the heat, made in the cap rather than around it.

The glass tube only picks up warmth from the device itself, so the chamber never gets too hot to handle. The electromagnetic field is designed to stay contained within the unit. A magnetic stand on the housing holds your device upright between draws and gives a hot cap a safe place to cool.

The display shows power and time, from 30 to 100 watts in 5-watt steps, and the timer runs from 10 to 60 seconds, with a hard cutoff at 60 seconds for safety. Your last settings are remembered between sessions, and the screen flips 180° so it reads correctly from either side of the table. Each battery has its own level indicator.

Lower power settings give the best flavour: around 30 to 40 watts roasts gently and gets the most out of a load. The upper half of the range heats fast for a denser draw. The heater also regulates itself and delivers only what the metal in the chamber can absorb. Even at a high setting, a small cap never takes more power than it can handle.

The YLL 3.0 is a popular choice for heating the Tempest 2. Few heaters have both the coil size and the full 100 watts to drive the Tempest 2 properly. Set the ceramic insert so the top of the vertical slits on the Tempest head stays just visible. Drop the device in and wait for the click that says the cap is ready.

With the stock ball fill, 65 watts with a 35 to 40 second timer is the optimal setting. Go to 80 watts and 30 to 35 seconds when you want it quicker. Heavier ball materials such as stainless steel take longer to saturate, but they hold their heat for longer; silicon carbide and glass reach the click fastest, so adjust the timer slightly to match your fill.

For DynaVap use, add the DynaVap silicone adapter (sold separately). It centres a standard DynaVap tip in the wide chamber so the device stands straight instead of leaning against the glass, which is what keeps the roast even from one side of the tip to the other. Without the adapter, only oversized caps sit correctly.

Settings are simple: around 65 to 75 watts suits the stainless caps of the M series for a balanced draw. Drop the power for a lighter taste, raise it for a denser finish. Titanium caps conduct heat faster and need less power. Lift the device at the click; push far past the click and roasting turns into burning.

The glass tube lifts out for cleaning, and a spare glass tube and a spare ceramic insert come in the box, so you have the wear parts covered from the start. The depth-adjustable insert is more than a spacer: seat your device higher and the heat concentrates near the tip for flavour. Seat it deeper and the heat drives further down for maximum extraction.

The chamber lights up while it works, and you can switch the light off to save battery. The housing is a flat-bottomed block measuring 136 × 67 × 41 mm. It stays put on a desk, so you can operate it with one hand.

The YLL 3.0 runs on two 21700 batteries, which are not included. We recommend a pair of Reliance RS50 cells: 5000 mAh each is enough for a full day of sessions. Owners of earlier induction heaters know that replaceable cells buy years of life: fresh batteries slot in the moment old ones fade.

Charging is onboard through USB-C, and it is quick for cells this large. Only a cable ships in the box. If you need a wall charger, the USB-C Fast Charger (45W) pairs well and will also charge your USB-C vaporizers. Start a heating cycle while the unit is plugged in and charging pauses, then resumes on its own. The magnetic door pops open with a fingernail, and the polarity is moulded into the bay. A swap takes seconds. An Xtar X2 external charger keeps a second pair ready so you never have to wait.

1. Batteries: Pop the magnetic door, insert two 21700 cells matching the moulded polarity marks, and charge fully over USB-C.
2. Power on: Press the power button. The display shows your saved watts and seconds.
3. Setting power: Double-click, then use + and − to choose 30 to 100 watts. The timer works the same way, from 10 to 60 seconds.
4. Insert depth: Adjust the ceramic insert so your device sits at the right height. Keep the top of the slits visible on a Tempest 2, and seat a DynaVap in its adapter.
5. Heating: Drop the device in. The cycle starts on its own and stops at the click, when the timer ends, or the moment you lift the device out.
6. Between draws: Park the device on the magnetic stand and let the cap cool before reloading.

The Ispire Wand is the other induction heater we carry. It is a wand-shaped unit with a built-in battery, comfortable to hold and designed around DynaVap-sized caps.

The YLL 3.0 gives you adjustable power and time while the Wand keeps things simple. The larger coil and maximum output of 100 watts on the YLL 3.0 make it the right heater for the Tempest 2 and other devices with large caps. Replaceable batteries are the advantage that pays off over the years: induction heaters drain cells hard, and swapping a worn pair costs far less than buying a new unit.

Choose the Wand for a DynaVap-only setup with no settings to think about. Choose the YLL 3.0 for the Tempest 2, mixed devices, or full control.
