Is the Uwell Caliburn G3 worth buying?

Yes, the Uwell Caliburn G3 is absolutely worth buying if you're looking for a high-quality MTL (mouth-to-lung) pod system. It's one of the best MTL pods available in 2026, with exceptional flavor quality, a smooth and satisfying draw, a long-lasting 1000mAh battery, and premium build quality. The Caliburn series has been a fan favorite for years, and the G3 continues that tradition with improvements in every area. If you prefer a tight, cigarette-like draw and want the best possible flavor from a pod system, the G3 is an excellent choice.

Which is better: Caliburn G3 or Vaporesso XROS 4?

It depends on what you're looking for. The Caliburn G3 has slightly better flavor quality and a more natural MTL draw, making it ideal for former smokers and MTL purists. The Vaporesso XROS 4 has more features — adjustable airflow on the pod, a wider range of coil options including restricted DTL, and a larger 3ml pod capacity. The XROS 4 is also slightly more versatile if you want both MTL and some DTL capability. Both are excellent pod systems. If you want the absolute best MTL flavor and draw, go with the G3. If you want more versatility and features, go with the XROS 4.

How long does the Caliburn G3 battery last?

The Uwell Caliburn G3 has a 1000mAh internal battery, which is above average for a pod system. With regular use (about 3-4ml of e-liquid per day), you can expect the battery to last a full day — typically 8-12 hours between charges. Light vapers can get 1.5-2 days of use on a single charge. The device charges via USB-C at about 0.6A, so a full charge takes roughly 60-75 minutes. The battery indicator lights on the front show you how much charge is left, and the device has a 10-second cut-off and multiple safety protections.

How long do Caliburn G3 coils last?

On average, Caliburn G3 coils last 7-14 days with regular use. The 1.0Ω mesh coil (our favorite for MTL) typically lasts 10-14 days for most vapers, while the 0.8Ω coil lasts slightly less at 7-10 days. Coil life depends on several factors: how often you vape, the sweetness of your e-liquid (sweeter e-liquids gunk up coils faster), your wattage setting, and whether you properly prime new coils. Uwell's Pro-FOCS coil technology helps extend coil life compared to older Caliburn models.

Can you use salt nicotine in the Caliburn G3?

Yes, the Caliburn G3 works great with salt nicotine e-liquids. In fact, it's ideal for salt nic — the MTL draw and lower wattage range (12-20W) are perfect for higher-nicotine salt e-liquids. Most MTL vapers use 20-50mg salt nicotine, and the G3 handles all of them well. The smooth draw and excellent flavor make salt nic taste great without being harsh. If you're coming from smoking and using high-nicotine salt e-liquids to quit, the G3 is an excellent choice.

Is the Caliburn G3 good for quitting smoking?

Yes, the Caliburn G3 is one of the best pod systems for quitting smoking. The tight, natural MTL draw closely mimics the feel of smoking a cigarette, which makes the transition easier for many people. The excellent flavor means you won't feel like you're missing out, and the device is simple and intuitive to use — no complicated settings to figure out. Pair it with a good salt nicotine e-liquid at an appropriate strength, and you've got a solid smoking cessation tool. Just make sure to follow the recommended nicotine strength guidelines and work with a healthcare professional if needed.
