At its core, the Duplex 2 is a 510-thread battery that changes roles depending on the attachment. You can screw in either a standard oil cartridge, the included Onyx Atomizer with dab chamber or the XL Nectar Tip. The latter is located on the underside and is dipped directly into the wax jar — eliminating the need to load a chamber. All three attachments are included, so they are not accessories that need to be purchased separately.
What IntelliThread actually controls
Ooze calls its attachment detection IntelliThread. The device checks what has been screwed in — cartridge, atomizer or nectar tip — and sets the appropriate resistance. In practice, this means that a different resistance applies to the sub-ohm operation of the Onyx Atomizer than to an oil cartridge, and the user does not need to adjust anything. This is not temperature control in the true sense; the applied voltage is regulated, not a target temperature.
The four voltage levels and their colors
The levels are 2.7 V (green), 3.2 V (blue), 3.7 V (yellow) and 4.2 V (red). Three clicks on the trigger switch between them. The same indicator also shows the battery level: one illuminated segment represents 0 to 25 per cent remaining charge, two represent 25 to 50, three represent 50 to 75 and all four represent 75 to 100 per cent. To check the charge level, simply count how many segments are illuminated.
Operation via the trigger
The Duplex 2 is operated not with a push button but with a trigger that you pull. Five clicks switch it on and off, three change the voltage, and two start Sesh Mode — a 15-second heating cycle during which you can inhale without holding the trigger. Holding it continuously activates manual heating. The magnetic trigger plate can be removed, and a vibration signals changes in status.
The difference from the Duplex Pro
Both models have the same 900-mAh battery and four voltage levels, but differ in how cartridges are fitted. The Duplex Pro uses magnetic 510-thread adapters: the cartridge is screwed onto an adapter and placed in a chamber — wider cartridges do not always fit inside it. The Duplex 2 does away with this adapter; the cartridge is screwed in directly and disappears completely inside the housing. On the Duplex 2, only the removable trigger plate is magnetic.
What the manufacturer leaves unspecified
Ooze provides no information on three points: there is no temperature specification in degrees Celsius, no stated charging time and no manufacturer specification for the number of draws per charge. The four voltage values are the only reliable performance figures. When using a cartridge or atomizer, the hole into which the XL tip is screwed also serves as a Carb Cap — this too is information from the manufacturer, not a test result.
The Ooze Duplex 2 can be used with 510-thread oil cartridges and concentrates. Two attachments are included for this purpose: the Onyx Atomizer with dab chamber and the XL Nectar Tip for dipping. The device is not designed for dry herbs.
The Duplex 2 offers four voltage levels: 2.7 volts, 3.2 volts, 3.7 volts and 4.2 volts. The indicator changes color from green through blue and yellow to red, so the selected level remains identifiable without a display.
The battery level is indicated by the number of illuminated segments: one represents 0 to 25 per cent remaining charge, two represent 25 to 50, three represent 50 to 75 and four represent 75 to 100 per cent. The battery has a capacity of 900 mAh.
The main difference between the Duplex 2 and the Duplex Pro is how the cartridge is fitted: the Duplex 2 accepts cartridges directly via its thread, whereas the Duplex Pro uses magnetic adapters and an open chamber into which wider cartridges do not always fit. In the Duplex 2, the cartridge sits completely inside the housing.
Yes, the Duplex 2 supports pass-through charging and can continue to be used while connected to the cable. Ooze does not specify a charging time.
Sesh Mode is a 15-second heating cycle started by clicking the trigger twice. During the cycle, you can inhale without holding down the trigger.
No. When using a cartridge or Onyx Atomizer, the opening into which the XL Nectar Tip would otherwise be screwed performs the function of a Carb Cap. There is no need to purchase one separately.
No. Ooze specifies only voltages for the Duplex 2, not a target temperature in degrees Celsius. Anyone looking for control accurate to individual degrees will not find it on this device.
