Description

The Uwell Caliburn G4 Classic is a refillable pod system with a built-in 1400-mAh battery and up to 35 W. The set contains two GPP V2 pods with mesh coils, 0.4 ohm for DL and 0.6 ohm for RDL. Each holds 3 ml and is filled from the side. This version has a silver housing.

Battery and power

The battery is built in and charges via USB-C at 5 V and 2 A. Maximum power is 35 W, with power automatically adjusted to the inserted pod. The pods are matched to this: the 0.4-ohm pod is optimised for 35 W and the 0.6-ohm pod for 25 W.

Pod and coils

GPP V2 pods come with 0.4, 0.6, 0.9 and 1.2 ohm. The coils are built in and are replaced with the whole pod. Filling is through a silicone plug on the side, without removing the pod. The device has no display.

You can find replacement pods with 0.4, 0.6 and 0.9 ohm among the Pods with coils.

Operation

Two draw sensors start the device; alternatively, use the button. Five clicks switch it on and off, and two clicks lock the button. An RGB LED at the bottom shows battery level, operating status and error messages. The slider adjusts airflow continuously. Draw resistance also changes when you rotate the pod by 180°.

Getting started with the Caliburn G4 Classic

  1. Charge the device via USB-C before first use. A cable is not included.
  2. Fill the pod from the side and close the silicone plug again.
  3. Leave the pod for a few minutes to let the coil soak. Otherwise, it may scorch (dry hit).
  4. Fit the pod and switch on the device with five clicks.
  5. Adjust the airflow using the slider and start with short draws.

Genug Leistung!

Leistung mit 35 W ist für mich mehr als ausreichend.

One small catch

Colour-wise the silver matches exactly what the photos promised. What sold me: no wavering in the vapour, however full the charge is. In use since Sunday evening, and I had the controls down by the first evening.
