UK vape hardware, explained
Vape hardware, compared properly.
Device Watch UK reads the spec sheets so you do not have to guess. We explain what wattage range, chipset features, battery capacity and pod limits actually mean, category by category, based on published manufacturer specifications.
| Spec | Pod kit | Sub-ohm kit |
|---|---|---|
| Typical wattage | 5–25W | 40–220W |
| Battery format | Internal, fixed | often18650/21700 |
| Draw style | MTL | DTL |
| Tank/pod limit | 2ml (UK reg.) | Varies by tank |
Compare by category
Four ways UK vapers usually think about hardware. Each category covers different priorities, from airflow control to charging format.
Pod Kits
Compact, MTL-focused devices with sealed or refillable pods capped at 2ml under UK regulation. Lower wattage range, simpler controls.
Sub-ohm
Higher-wattage DTL devices, usually with removable 18650 or 21700 cells and adjustable airflow for bigger vapour production.
Battery & Chipset
mAh capacity, charge time, temperature control and puff counters. What the numbers on a spec sheet mean for daily use.
Accessories
Spare coils, drip tips, replacement pods and charging leads. Compatibility is brand and model specific, so always check before buying.

How we compare
Every comparison on Device Watch UK is built from published manufacturer specification sheets and official UK regulatory sources, not in-house lab testing. We do not run coil longevity tests, battery drain benchmarks or vapour density measurements ourselves, and we say so plainly rather than implying otherwise. Where a spec varies between markets or hardware revisions, we note that it varies instead of picking a single figure.
