XROS 4 Pod Vape Kit

The Vaporesso XROS 4 pod vape kit pairs an approximately 1000mAh battery with a 0.96-inch colour screen, the Smart AXON chip and three manual power modes covering 5-30W. It runs on COREX 2.0 mesh in the box and accepts the newer COREX 3.0 pods on the same magnetic connector, which keeps the kit relevant well after the launch of newer XROS models. The XROS 4 sits in the wider Vaporesso XROS pod kit range as the entry-price flagship for 2026, made by SMOORE.

Compared with the slightly newer XROS 5 the XROS 4 keeps the manual fire button, dual activation and the same broad MTL-to-RDL airflow ladder, just with the older AXON chipset and a smaller 0.96-inch screen rather than the 0.88-inch HD interactive display. For shoppers who want the proven XROS form factor without the flagship price, the XROS 4 sits between the screenless XROS 4 Mini and the current generation, and remains a genuine product backed by Vaporesso's UK authorised distribution.

Three Power Modes and the Smart AXON Chip

The XROS 4 runs three manual power modes on the fire button - eco, normal and boost - giving you finer control than the fixed-output XROS 4 Mini. Eco stretches the battery further on tighter MTL pods, normal is the everyday setting most vapers settle on, and boost pushes more power through the coil for warmer hits or higher-VG e-liquid.

The Smart AXON chip also reads the resistance of whichever pod is fitted and matches a sensible wattage automatically, so a freshly inserted 0.4-ohm RDL pod and a 1.2-ohm MTL pod each get their correct output without you touching the menu. Three quick clicks of the fire button cycles through the manual modes, with the 0.96-inch colour screen confirming the change.

Battery Life and USB-C Charging

The approximately 1000mAh internal battery is the same capacity as the XROS 4 Mini, but the three-mode output ladder gives you control over how quickly you draw it down. Sitting in eco mode on a 0.8-ohm or 1.0-ohm MTL pod will comfortably see a moderate vaper through a full day; boost mode on the 0.4-ohm RDL pod will drain noticeably faster, which is normal for higher-wattage sub-ohm-style vaping.

Charging is handled by USB-C at 2A, with a flat-to-full top-up coming in at approximately 30 minutes. The colour screen shows live battery percentage rather than the LED dot-pattern used on older XROS models, so you can plan a top-up before the kit cuts out mid-session.

MTL and RDL Airflow Control

The side airflow slider runs from fully closed for tight cigarette-style MTL through to wide open for restricted direct lung. Pair the slider with the correct pod resistance and the XROS 4 covers most adult vaping styles on a single device: a 1.0-ohm or 1.2-ohm pod with the slider almost closed for a true MTL cigarette draw, an 0.8-ohm pod with the slider mid-open for a 50/50 nic salt MTL, or the 0.4-ohm RDL pod with the slider fully open for higher-VG freebase.

Dual activation means the auto-draw sensor and the fire button both fire the coil at the same time. Most vapers stay on auto-draw for everyday use and only reach for the button when they want a longer, more controlled inhale or to fire the kit before a draw to pre-heat the coil on cold mornings.

Pod Compatibility

The XROS 4 accepts the full XROS pod ladder from 0.4 ohm through to 1.2 ohm. In the box are two original XROS COREX 2.0 replacement pods - a 0.4-ohm for RDL and an 0.8-ohm for MTL - and the same magnetic connector also accepts the newer XROS COREX 3.0 replacement pods across the 0.4-ohm to 1.0-ohm resistance range. The 2.0 pods give a warmer, broader resistance ladder that some long-term XROS vapers prefer; the 3.0 pods use Vaporesso's Hive Mesh for a richer flavour profile and longer coil life.

That dual-generation compatibility is the main reason the XROS 4 still sells in 2026 - new pod releases on the COREX 3.0 platform continue to drop straight into the kit without any adaptor or firmware update, so a kit bought today is not tied to a single coil generation.

How to Use the XROS 4

Out of the box the kit comes with the 0.4-ohm COREX 2.0 pod pre-installed. Five rapid clicks of the fire button turn the device on or off, and the same five-click sequence also locks and unlocks the kit so it will not fire in a pocket or bag.

1. Pull the pod out, lift the silicone side plug, drip your nic salt e-liquid or 50/50 freebase in to the fill line, then push the plug firmly back into place.
2. Drop the pod back into the kit and stand it upright for approximately three to five minutes so the wick can saturate - skipping this is the most common cause of a burnt first puff.
3. Click the fire button three times to step through eco, normal and boost power modes; the 0.96-inch screen confirms the active mode.
4. Slide the side airflow to taste, then either inhale on auto-draw or hold the fire button for a longer, more controlled draw.

Available Colourways

The XROS 4 is available in ten UK colourways split across three finish families. Classic finishes cover black, blue, silver and green for shoppers who want a discreet pocket kit. The Specialty range pulls in Bloody Mary, Sunset Neon and Pastel Palette for something more distinctive, and the Metallic finishes - Champagne Gold, Lilac Purple and Pink Mint - sit between the two.

The XROS 4 is a genuine Vaporesso product distributed through authorised UK channels and meets UK TPD standards on the 2ml refillable pod capacity. For the wider Vaporesso line of pod kits, sub-ohm devices and accessories, the full Vaporesso brand collection sits alongside this kit.
