The higher box price that works out cheaper per pod
This is the top-fill version of Uwell's GPP cartridge, boxed as five 4-packs for 20 pods total, £43.99, across four resistances from 0.4 to 1.2 ohm. It is the correct reorder pod for Caliburn G4 Pro, G5 Lite and G5 Lite SE alike, since all three currently ship with the same GPP generation.
The box price sits higher than the side-fill GPP cartridge, but the real comparison is per pod, not per box. This one packs four pods to a retail pack against the side-fill's three, which works out to roughly £2.20 a pod here against about £2.27 for the side-fill version. The higher headline price is actually the better deal per unit.
- Twenty pods per trade box, packed as five 4-packs
- Works out cheaper per pod than the side-fill sibling despite a higher box price
- Top-fill design avoids the low-liquid angle a side-fill pod struggles with
- The correct reorder for G4 Pro, G5 Lite and G5 Lite SE alike

Why the box price alone is the wrong number to compare
Comparing two cartridge boxes on price tag alone is an easy way to quote a customer the wrong recommendation. This top-fill box costs £43.99 against the side-fill's £33.99, which looks like a clear win for side-fill until the pack sizes come into it: this box holds 20 pods, the side-fill box holds 15. Divide it out and top-fill is the cheaper pod, not the pricier one. Always work from the per-pod figure when a customer asks which is better value.
Beyond price, top-fill genuinely changes the refill experience: filling from the top avoids the awkward low-liquid angle a side-fill pod needs once it runs low, which cuts down on spills at the point customers usually get it wrong.
Which fill style to stock, and for which kits
Stock this top-fill version as the default reorder behind any G4 Pro, G5 Lite or G5 Lite SE sold, since it is both the better per-pod value and the easier refill. Offer the side-fill version only to customers who specifically prefer that fill style; it fits the same three kits, so the choice is about handling preference, not compatibility. The Uwell brand page and wider refillable vape pods category set the fuller range context. Age-verified trade throughout.
