Uwell Caliburn G4
The Caliburn G4 has a 1300mAh battery and an output of up to 35W, with 0.4Ω, 0.6Ω and 0.9Ω pods. Use the 0.9Ω pod with 20mg nic salts for a tight, cigarette-style draw, or the lower-resistance pods for a looser draw with lower-strength liquids. If you want more battery, the Caliburn G4 Pro has an 1800mAh battery. Shop Uwell and Caliburn pods.
Vaporesso XROS 4 Mini
The XROS 4 Mini is the smallest of the three, with a 1000mAh battery and a 2ml top-fill pod. A big plus is that XROS pods fit across the XROS range, so spare pods are easy to find. Shop Vaporesso and XROS pods.
OXVA Xlim Pro 3
The Xlim Pro 3 has the biggest battery here at 1500mAh, with fast charging, and works with both XLIM V3 and XLIM EZ pods. It suits vapers who want long battery life from a slim kit. Shop OXVA and Xlim pods.
