Focus V Carta 2 Guides & Niches
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 full charge via USB-C takes about 90 minutes. 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 full charge takes around 90 minutes.
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.
