Uwell Caliburn GPP 3 mL replacement pods come as a four-pack of refillable cartridges. Their main advantage over the 2 mL version is simple: each pod holds more e-liquid, so you can usually go longer between refills under the same conditions. The pack is intended for compatible G Pod Platform devices. It contains pods only, not a vape device or bottled e-liquid.

Confirm G Pod Platform compatibility first

GPP is Uwell's shared G Pod Platform cartridge family for supported Caliburn G5, G4 and G3 models. It includes several newer pen-style and KOKO devices. A shared platform makes replacement shopping easier when you stay within it, but the Caliburn name appears on older systems too. Check the model printed on your device and the compatibility information on the pack. Do not rely on a similar-looking mouthpiece or a broad Caliburn label.

The shows the version you can actually select. Check its resistance and fill style before buying. Uwell shows 3 mL GPP cartridges in 0.4, 0.6, 0.9 and 1.2 ohm options across the platform, though the stock and variations on a particular listing determine what you will receive.

3 mL GPP four-pack listing

Choose capacity and resistance separately

The 3 mL capacity concerns how often you may need to refill. Resistance concerns the draw. A lower-resistance cartridge can give a warmer, airier restricted direct-lung feel when the device supports it. A higher-resistance cartridge generally suits a cooler, closer mouth-to-lung pull. Airflow settings, power and e-liquid also affect the result, so use your current pod as a reference when choosing a replacement.

If you already like the way a cartridge vapes and simply want fewer refills, choose the same resistance in the 3 mL capacity if that variation is available and compatible. If you are changing resistance as well, expect the draw to change. The 2 mL GPP pod guide explains the smaller option for people who prefer shorter refill intervals or switch flavours more often.

Filling and using a 3 mL cartridge

Find the fill port on the pod in your hand. Some GPP cartridges use a top-fill opening while others fill from the side. Add suitable e-liquid, close the port securely and let a fresh wick saturate before taking the first puff. Watch the liquid level during use, especially with a lower-resistance pod at higher output. Refill before empty rather than waiting for the first dry taste.

Uwell's U² design aims to limit leakage through the pod and airflow path. Good routine care still matters: keep the opening sealed, wipe condensation when it collects and replace the cartridge if flavour becomes weak or unpleasant. A larger reservoir reduces refill frequency; it does not make a coil last indefinitely.

Is the 3 mL pack right for you?

Choose this pack if your device supports GPP and you want more liquid in each of your four spare cartridges. Verify the selected resistance, fill method and capacity on the product page before checkout. If you are unsure which device you own, identify it first; compatibility is the deciding factor, while capacity and resistance fine-tune the routine afterward.
