About this vaporizer
Focus V Carta 2 is a smart e-rig for concentrates that dissolves the boundary between home devices and portable ones. Anyone who wants to vaporize concentrates such as wax, shatter, or live resin without relying on a large glass dab rig will find the Carta 2 a device that fills exactly this gap — with app control, interchangeable atomizers, and passthrough charging for maximum flexibility.
The heating system is based on convection: hot air is drawn through the concentrate, enabling a cleaner and more efficient extraction than pure conduction coils. Interchangeable atomizers are a central feature of the Carta 2: depending on the concentrate type, personal preference, or budget, you can switch between different coil types without having to replace the entire device. Quartz atomizers, sapphire coils, and titanium options are available as needed.
The Focus V app allows precise heat profiles with single-degree control up to 335°C. Temperature precision is particularly important for concentrates: too low and the material does not vaporize completely, too high and the most delicate terpenes destroy themselves. Saved profiles help repeat the optimal settings for different material types and density variations.
With a 2000 mAh battery and passthrough charging, the Carta 2 is equipped for longer sessions. Water attachment compatibility is not a bonus option with an e-rig but an integral part of the experience: the built-in water filtration system cools and filters the vapor before it reaches the mouthpiece area. A heat-up time of 30 seconds is very fast for an e-rig.
The dosing capsule system simplifies preparation: concentrates can be pre-portioned into capsules, resulting in less mess and more precise dosing. A one-year manufacturer's warranty is standard for a device in this class. The Focus V Carta 2 is not the cheapest e-rig on the market, but it is one of the best-equipped in its price range.

The built-in OLED display shows temperature, session length, battery status, and a running dab counter.
What sets the Carta 2 apart from most e-rigs: the battery (an 18350 cell) is user-replaceable. It also supports wireless Qi charging and passthrough operation. Check current prices from multiple European shops in the price comparison. All Focus V products are listed on the Focus V brand page.

Intelli-Core: 360° Convection for Herbs and Concentrates
The core of the Carta 2 is the 360° Intelli-Core heating element. It works on the convection principle: hot air flows evenly through the material rather than heating one side. The result is more uniform extraction — fewer hot spots, better flavor.
The temperature range of 185 to 335 °C covers both use cases. Lower settings (185–220 °C) suit dry herbs, focusing on terpenes and aroma. Upper settings (250–335 °C) are designed for concentrates, where waxes and oils need to fully vaporize.
Heat-up time at the highest setting is around 30 seconds. At lower temperatures it is slightly faster. For a dual-use convection device, that is a solid number — not a record, but not a bottleneck either.
OLED Display and App: Full Session Control
The OLED display on the Carta 2 shows all key parameters at a glance: current temperature, session length, battery charge level, and a built-in dab counter that tracks every completed session. The counter is genuinely useful for tracking usage or comparing different material types and temperature combinations.
The Bluetooth app (Android and iOS) lets you set temperature and session length with precision. Session length is adjustable from 20 to 60 seconds — short dabs for quick hits, longer sessions for larger herb loads. The app also stores custom LED color presets and sends a notification when the target temperature is reached.
If you prefer not to use the app, all basic functions can be set directly on the device. The app is a bonus, not a requirement.
Borosilicate Glass Bubbler with Increased Water Capacity
Which parts are included cannot be fully confirmed with the evidence available here. More water means a longer cooling and filtration path — vapor loses temperature noticeably before it reaches your mouth. At high concentrate temperatures, this makes a clear difference in harshness.
Borosilicate glass is tempered and significantly more resistant to thermal shock than regular glass. The bubbler detaches from the main body, making cleaning straightforward. The system is compatible with standard 14mm WPA attachments, so the Carta 2 can also be used with an external water pipe.
Prefer a dry draw? You can use the Carta 2 without water in the bubbler — the vapor path stays the same, just without filtration. For herbs at low temperatures, that is a reasonable option.
Replaceable Battery (18350) and Qi Charging — a Real Advantage
The biggest practical advantage of the Carta 2 over most e-rigs: the 18350 lithium battery is user-replaceable. A spare cell costs just a few euros and swaps in seconds. In practice, that means unlimited runtime with enough spare batteries and no dependence on a wall outlet.
Capacity is 2,000 mAh. Expect around 20 to 25 sessions per charge — fewer than e-rigs with built-in 3,000+ mAh batteries, but the swap system more than compensates. The available sources do not indicate a duration for a full battery charge. The Carta 2 also supports wireless Qi charging — just set it on a Qi pad.
Passthrough operation is supported as well: the Carta 2 can be used while charging (both USB-C and Qi). At home, it acts like a desktop unit you can still grab and take with you.
Who Is the Focus V Carta 2 For?
The Carta 2 is aimed at users who want flexibility in material. If you alternate between concentrates and dry herbs, this device handles both without compromise. Buying a separate e-rig and herb vaporizer would cost more and add clutter.
The replaceable battery makes the Carta 2 especially attractive for users who want to run their device long-term. Most e-rigs are limited by battery degradation. With the Carta 2, you just swap the cell.
It is less suited for beginners with no experience of e-rigs or convection devices. Filling the bubbler, configuring the app, and cleaning the atomizer require some routine. At 422 grams and 18.4 × 6.7 cm, it is not a pocket device, but it fits comfortably in any backpack. Warranty is 1 year.

Green = better value
Open in full comparison →Yes. The Carta 2 is a dual-use e-rig for both concentrates and dry herbs. The 360° Intelli-Core convection element covers 185 to 335 °C. Low settings (185–220 °C) suit herbs; high settings (250–335 °C) suit concentrates.
Yes — that is a standout feature. The Carta 2 uses an 18350 lithium cell that swaps out in seconds. A spare cell costs a few euros. This makes the Carta 2 viable long-term without depending on battery degradation.
The 2,000 mAh battery delivers roughly 20 to 25 sessions per charge. A verified value for the charge time to 100% is not available here. Wireless Qi charging is also supported. Passthrough operation works while charging.
The OLED shows temperature, session length, battery level, and a dab counter that logs every completed session. Via the Bluetooth app you can fine-tune temperature and session length (20–60 seconds) and save LED color presets.
The app is called Focus V and is available for Android and iOS. It connects via Bluetooth for temperature and session control. The device also works without the app — all core settings are accessible directly on the Carta 2.
For dry herbs: 185–220 °C (terpenes and flavor), 220–235 °C (all-rounder). For concentrates: 250–290 °C (flavor-focused), 290–335 °C (thick clouds, fast extraction). Fine adjustments are made through the app or directly on the device.
Yes. The Focus V Carta 2 supports Qi wireless charging. Just place it on a compatible Qi pad — no cable needed. USB-C is also available. Either way. A duration for a complete charge is not documented.
Swab the still-warm atomizer with a cotton swab after each session. Rinse the glass bubbler with warm water regularly. Weekly, soak atomizer and glass in isopropyl alcohol (90%+), rinse, and let dry completely. Change the bubbler water every 1–2 days.
The Carta 2 weighs 422 grams (14.9 oz) at 18.4 × 6.7 cm. For an e-rig with a glass bubbler and replaceable battery, that is a normal figure. It fits in a backpack but not a trouser pocket.
Focus V offers a 1-year warranty from the date of purchase. Since the battery is replaceable, the most common long-term issue with e-rigs (battery degradation) is a non-issue — swap in a fresh cell and the device runs like new.
