Yllvape YLL 3.0

A coil inside generates a high-frequency magnetic field. When you hold a ferromagnetic tip inside it, the field induces eddy currents directly in the metal. The metal heats itself from within — not from the outside via a flame. The heat is therefore generated all around, rather than unevenly as with a lighter.

This has two practical consequences: no combustion gases reach the herb, and the result is repeatable. With the same tip and the same wattage and seconds settings, the YLL 3.0 heats very consistently. With a flame you sometimes hit the spot and sometimes you don't — with induction you set it once and get the same result every time. How quickly a tip heats up depends, according to YLLVape, on the material and wall thickness of the cap as well.

The YLL 3.0 can be adjusted from 30 to 100 watts, along with the heating duration in seconds. Both values are shown on the display. Lower wattage heats more slowly and gently — ideal for flavor-focused draws. Higher wattage brings the tip up to temperature more quickly, suited to dense vapor in a single draw.

The maximum of 100 watts is the main reason to choose the YLL 3.0 over the smaller YLL 2.0 (30 to 60 watts): larger tips and thicker caps require more energy to heat through quickly. Those using standard DynaVap tips will typically operate in the mid-range; the headroom above is there for larger tips and faster sessions.

The heating chamber of the YLL 3.0 is depth-adjustable. Using the ceramic insert, you can set how deep the tip sits within the coil; two ceramic inserts are included, with additional ones available as spare parts. The ideal position is one where the hot section of the tip sits in the center of the magnetic field. If it sits too deep or too shallow, it will heat unevenly.

To allow a DynaVap to sit straight and stable in the chamber, YLLVape also offers a silicone adapter. This adjustability sets the YLL 3.0 apart from simpler heaters with a fixed chamber depth; according to the manufacturer, its larger coil makes it compatible with more devices. For the TEMPEST 2, MAD Heaters includes a 3 mm spacer that sits beneath the ceramic insert (details below).

The YLL 3.0 runs on two 21700 batteries, which are not included. Compared to the YLL 2.0, which uses two 18650 cells, YLLVape cites a larger battery capacity and longer sessions with less frequent battery changes.

Charging is via USB-C, with a cable included. Alternatively, you can charge the cells externally in a separate charger. Those with two sets of batteries can simply swap them out on the go and be ready to use immediately — an advantage of the replaceable design over built-in batteries.

The YLL 3.0 requires high-drain 21700 cells, as up to 100 watts draws briefly high currents. YLLVape recommends:

• Molicel P42A (INR-21700-P42A, 4,200 mAh, 45 A, Flat Top).

Important: use cells with a flat positive terminal (Flat Top), as per the manufacturer's recommendation. Both cells should be the same model, same state of charge, and same age — mixed batteries place greater strain on one cell and shorten its lifespan. Cheap no-name cells without a stated current rating have no place in a high-performance device.

The YLL 3.0 is designed for devices with a ferromagnetic tip:

• DynaVap devices
• MAD Heaters TEMPEST 2 – MAD Heaters lists the YLL 3.0 in its shop as a heater for the TEMPEST 2
• Hyperdyn by DynaVap – according to YLLVape, it fits in the chamber with an 18 mm internal diameter, unlike the YLL 2.0
• other devices of a similar size

Not suitable are devices without a metal tip, such as purely electronic vaporizers — induction only heats conductive metal. For other devices, check in advance whether the tip and diameter are compatible.

YLLVape gives no temperature figures in degrees – you work with watts and seconds, using the DynaVap click as your indicator. A few reference points:

• Flavour/low: moderate watts, slightly longer heating time – the vapor stays mild.
• Dense clouds: higher watts, shorter time to the click.
• Larger tips/Hyperdyn: higher watts or more time, because more metal mass needs to be heated.

The practical approach: start with a mid-range setting, check after the first click, then adjust watts or seconds by one step. After two or three attempts you will have found your preferred values and can call them up again and again.

The YLL 3.0 is the more powerful evolution of the YLL 2.0. The differences:

• Power: 30–100 W (3.0) versus 30–60 W (2.0) – faster heat-up, more headroom.
• Batteries: dual 21700 (3.0) instead of dual 18650 (2.0) – longer sessions with less frequent changes.
• Chamber: removable glass tube with an 18 mm internal diameter, larger coil and chamber lighting on the 3.0, making it suitable for Hyperdyn and similarly sized devices.
• Display: rotatable 180° on the 3.0, fixed on the 2.0.

Anyone who only heats standard DynaVap tips and wants a smaller, lighter device will get by with the 2.0. Anyone who uses large tips, wants dense draws in a single session, or needs longer battery life is better served by the 3.0. The upgrade is worthwhile primarily because of the 21700 batteries, the larger chamber, and the higher maximum power.

Both are induction heaters, but with different philosophies. The Ispire The Wand offers temperature selection in degrees (approximately 120–425 °C, in 5-degree steps), runs on 2× 18650, and is designed primarily for concentrates. The YLL 3.0, by contrast, relies on watt and second control, 2× 21700, and the heating of dry herb devices such as DynaVap.

In short: the Wand is more versatile (degree display, concentrate use), while the YLL 3.0 offers up to 100 watts and an adjustable chamber depth as well as larger battery cells. Anyone who values a temperature readout in degrees and a dab function should go for the Wand; anyone looking for power and adjustability for DynaVap tips should go for the YLL 3.0.

The MAD Heaters TEMPEST 2 is a device with a ferromagnetic tip that can be heated by induction. MAD Heaters, the manufacturer of the TEMPEST 2, sells the YLL 3.0 in its UK and US shops as a heater for the TEMPEST 2. According to MAD Heaters, this version has its own firmware with a desktop mode: the device runs continuously on cable power, and the batteries are only charged to 70% to slow their aging. A 3 mm spacer for the TEMPEST 2 is also included.

Setup according to the manual: Remove the battery cover, place the C-shaped 3 mm spacer on the silicone pad at the bottom of the heating chamber, and replace the cover. Then, with the heater switched off, press the TEMPEST cap – along with the silicone pad and ceramic disc – down onto the spacer. This sets the correct insertion depth.

Settings: MAD Heaters publishes a table of watts and seconds for each ball material and cap. Two examples for starting from room temperature:

• Stainless steel cap with quartz glass balls (factory state): 60 W → 50–54 s, 80 W → 39–43 s, 100 W → 29–32 s
• Titanium cap with zirconia balls (factory state): 60 W → 45–50 s, 80 W → 35–40 s, 100 W → 27–30 s

Lowering the power means heating for longer; raising it means shortening the timer so nothing burns. If the cap is still warm from the previous session, the manual advises subtracting 8–12 seconds from the timer while leaving the wattage unchanged.

"The best" depends on what you need. The YLL 3.0 stands out with up to 100 W, large 21700 batteries, and an adjustable chamber – making it a strong choice for heavy users and larger tips such as Hyperdyn. Anyone who wants a degree readout and a dab function should look at the Ispire The Wand. Anyone after something more compact and affordable will find leaner alternatives in heaters like the DynaTec Orion V2 or the Cuboo Pro V2.

The YLL 3.0 is not a budget entry-level device – it is a performance unit, and the batteries are an additional cost. For someone who uses their DynaVap daily, runs several tips, and values repeatability, it is one of the obvious options.

According to YLLVape, the box contains the device, two glass tubes, two ceramic inserts, and a USB-C charging cable. The two 21700 batteries are not included – you need to purchase them separately (see battery recommendation above). Factor in these additional costs when comparing prices.

Useful accessories: an external 21700 charger (allows a spare set to charge simultaneously), a second set of batteries for uninterrupted use, and optionally the silicone adapter from YLLVape that keeps a DynaVap upright in the chamber. Glass tubes and ceramic inserts are available individually as spare parts. If you buy the YLL 3.0 from MAD Heaters, a 3 mm spacer for the TEMPEST 2 is also included; it is available there individually as well.

Two names circulate for the same device, so here is a clarification: the YLL 3.0 (YLL IH 3.0) is manufactured by YLLVape, a developer and manufacturer of portable vaporizers and accessories founded in 2019. MAD Heaters, the manufacturer of the TEMPEST, sells the device through its shops for the UK and the USA – which is why it sometimes appears as "MAD Heaters YLL 3.0". It is also sold directly through YLLVape and via other specialist retailers.

For you as a buyer this means: the technical specifications are identical everywhere (30–100 W, two 21700 cells, glass chamber). According to the shop, the MAD Heaters version includes its own firmware with a desktop mode and a 3 mm spacer for the TEMPEST 2 in the box. Otherwise the shops differ in price, shipping, and warranty handling – which is exactly what you can compare in the price table above.

• Tip does not heat up properly: Check the chamber depth – is the hot part of the tip centered within the coil? Adjust the ceramic insert if necessary. For large or thick-walled tips, increase the watts or seconds.
• Heating cycle ends too soon: The set heating time has elapsed – increase the seconds. If the device switches off immediately, check the battery charge and the correct seating of the cells.
• Weak performance: often caused by empty or unevenly charged batteries. Use both cells fully charged and of the same type.
• Uneven heating: tip inserted too deep or too shallow – adjust the depth.

The YLLVape YLL 3.0 is the right choice if you want to use your DynaVap (or a TEMPEST/Hyperdyn device) regularly and without a flame and value adjustable power, larger batteries, and repeatable results. The adjustable chamber and up to 100 watts make it, according to the manufacturer, one of the most versatile induction heaters on the market.

It is less suited to purely occasional users for whom a simple lighter suffices, or to anyone who needs a degree-precise temperature display and a dab function – in that case the Ispire Wand is the better choice. Also factor in the cost of batteries, as these are sold separately.
