Uwell is bringing a more affordable device within its Caliburn G series. The Caliburn G4 Mini features up to 35W of power with an 1100 mAh battery. Also new to the G Series is the control of the coating stiffness, which is now full slider control, following the example of the competition.

The manufacturer has chosen a minimalist look for the device. The dimensions are 112.75 × 24.1 × 14 mm. The weight then reaches, admirably small, 46 g. The front side contains only a notification LED. On the right side, there is a USB-C connector. On the left side you will find a slider to adjust the stiffness of the cover. The back side contains a window in the body through which the liquid level can be monitored without removing the cartridge.

The device now has a power output of up to 35W. The power is selected automatically according to the cartridge inserted. The device does not have an ignition button. It has an automatic coating.

CaliburnG4 Mini got new GPP cartridges. However, it is alsocompatible with those of the G3 version. The cartridges again offer the popular 0.4, 0.6 and 0.9 ohm resistances. They have a 3 ml capacity and top fill.Users running both MTL and RDL will find this to their liking . The pain of the predecessor's cartridges, leaking through the bottom weld, is a thing of the past thanks to the U2 technology that creates a well for the cartridge, which is then directly fed by the glow head. The entire bottom section is then further sealed by ultrasonic welding.The cartridges once again feature the Pro-FOCS kanthal mesh technology for that great flavor we've come to expect from Uwell.

The battery capacity has been increased to 1100mAh. It can be recharged with a 2A fast charge if needed.
