VapeExperts Review of the Focus V Carta 2
The Focus V Carta 2 heats to dabbing temperature in 8 seconds and lets you dial in concentrate sessions to the exact degree. This mid-range eRig pairs conduction heating with glass water filtration for smooth, flavorful draws.
We purchased the Carta 2 and tested it over several weeks of daily use. Its Intelli-Core atomizer and Bluetooth app deliver thick clouds with real temperature precision, and 11 sessions per charge keeps it running longer than most competitors at this price point. As of May 2026, it sits below the Puffco Peak Pro8.5 in both price and performance.
Focus V discontinued the Carta 2 in mid-2025 following a patent settlement with Puffco. The Carta Sport7.2 is now the current-production successor. Existing Carta 2 owners retain full warranty, app support, and access to replacement atomizers.
Build quality and ongoing atomizer costs prevent a top-tier recommendation. The Carta 2 earns its place for cloud chasers who want app control without flagship pricing, but buyers should factor in replacement parts before committing.
What's in the box
The Carta 2 ships in a compact nylon backpack-style carry bag. Inside:
Carta 2 base unit with OLED display
Intelli-Core atomizer with carb cap and silicone sleeve
Borosilicate glass bubbler
Silicone travel stopper for sealing the bubbler during transport
Dab tool
USB-C charging cable
Alcohol cleaning swabs and Q-tips
The bag is padded enough for transport but too small to fit extra accessories. No dry herb atomizer is included. That's a separate purchase.
Whether you own the Focus V Carta 2 or are still deciding — your thoughts and questions are welcome here.

Every vaporizer we cover is bought, lived with, and tested by the same small team. We log temperatures with an external thermocouple, run battery cycles to depletion, and spend at least two weeks on a device before we score it. No manufacturer has ever paid for, previewed, or influenced a review on this site.
The Carta 2 breaks down into three main components: the base, the atomizer, and the glass bubbler. Drop the atomizer into the base, seat the water-filled bubbler on top, align the airholes, and you're ready.
At 390 g and 165 mm tall, the Carta 2 fits in a cup holder and sits comfortably in one hand. The base combines aluminum with a rubberized silicone coating that absorbs impact and prevents slipping.
Glass bubbler cools vapor but demands careful handling
The borosilicate glass bubbler sits on top of the base and serves as both the water filtration chamber and mouthpiece. Fill it roughly two-thirds with water for effective cooling.
The glass is thicker than what you'll find on budget eRigs, but it remains the most fragile component. The included silicone stopper seals the water for transport. Drop protection extends to the rubberized base only, not the glass.
Atomizer durability varies with maintenance
The Intelli-Core atomizer uses ceramic heating elements and a quartz chamber surface. Community users report the stock atomizer lasting 3-6 months under regular use.
Some dedicated users have logged over 8,000 sessions on a single atomizer with consistent post-session swabbing. Skipping that maintenance shortens lifespan considerably.
Conduction atomizer heats in 8 seconds with 1°C precision
The Intelli-Core atomizer uses conduction heating with what Focus V calls 360° heat distribution. It reaches the set temperature in 8 seconds, one of the fastest heat-ups in the mid-range eRig class.
Temperature control spans 232°C to 371°C in 1°C increments. That range covers terpy low-temp flavor pulls through high-temp cloud production without restriction. The 0.12 g quartz chamber holds a comfortable dab size for single sessions.
Water filtration and carb cap control the draw
The glass bubbler is the Carta 2's biggest vapor quality advantage. Vapor passes through water before reaching your lips, producing smoother, cooler draws than pen-style concentrate vapes with no filtration.
Draw resistance sits in the moderate range. The built-in carb cap insert features a small choke hole that lets you regulate airflow mid-draw. Sipping slowly produces better flavor and prevents concentrate overflow.
Adding terp pearls (not included) to the chamber distributes heat more evenly and noticeably improves vapor density. Multiple users confirmed that terp pearls paired with a bubble carb cap transformed the experience. For live resin and terpene-heavy concentrates, start in the 250-315°C range to preserve flavor while still producing visible clouds.
Battery lasts 11 sessions on a single charge
The Carta 2 packs a 2000 mAh built-in battery that delivers roughly 11 sessions per charge. That outpaces most eRigs at this price point and covers a full day of moderate use.
Pass-through charging via USB-C means you never have to pause. Plug it in and keep going while it charges. A full recharge takes about 90 minutes from empty.
Focus V sells a wireless Qi charging dock (separately) with a 10,000 mAh internal battery that recharges the Carta 2 roughly 5 times. For heavy users, the dock eliminates battery anxiety. The battery is non-removable, so USB-C or the dock are your only options.
Drop your concentrate into the atomizer chamber, insert the atomizer into the base, and seat the filled bubbler on top. Five clicks of the power button turns the unit on.
The OLED display shows temperature, session timer, and battery level. Use the plus and minus buttons to adjust settings, then double-click to start heating. The Carta 2 vibrates when it reaches your set temperature.
Cleaning keeps performance consistent
After each session, swab the chamber with a dry Q-tip while still warm. This single step prevents buildup from hardening into flavor-killing residue.
For deeper cleaning, disassemble all three components and soak the glass and atomizer in isopropyl alcohol. Our eRig cleaning guide covers the full process. The glazed ceramic surface cleans more easily than coil-based systems, and users who swab after every session report much longer atomizer life.
App unlocks full control over temperature and presets
Bluetooth app adds depth without adding complexity
The Focus V Carta app (iOS and Android) connects via Bluetooth and opens up the full feature set. Adjust temperature, session timer duration, vibration intensity, and RGB LED presets from your phone.
The app stores session presets, enables remote start, tracks your total session count, and pushes firmware updates. That firmware capability is a real advantage. Focus V can improve performance after purchase without requiring new hardware.
OLED handles daily use without the app
You don't need the app for everyday sessions. The three-button interface covers temperature, timer, LED presets, and device lock. The OLED display reads clearly indoors but washes out in direct sunlight.
Navigating menu options with three buttons takes some practice. Most users find the app more intuitive for initial setup, then rely on the physical controls day to day.
How the Carta 2 compares to the competition
Three head-to-head matchups cover the eRigs Carta 2 buyers cross-shop most as of May 2026.
Carta 2 vs. Puffco Peak Pro
The Puffco Peak Pro is the Carta 2's most direct competitor and the benchmark for app-controlled eRigs. Its 3DXL ceramic chamber delivers more accurate real-time temperature regulation and more consistent flavor across a full session.
The Carta 2 counters with faster heat-up (8 seconds vs. the Peak Pro's 20-second ramp) and a lower asking price. The Peak Pro's 30 sessions per charge outpaces the Carta 2's 11, but the Carta 2 gets you dabbing faster. For the detailed breakdown, compare the Carta 2 and Puffco Peak Pro side by side.
Carta 2 vs. Ispire Daab
The Ispire Daab7.5 takes a completely different approach with induction heating and an all-glass air path. It eliminates atomizer replacement costs entirely, lowering long-term ownership cost. Flavor purity edges ahead thanks to the glass-only vapor path with zero ceramic contact. Ispire has discontinued the Daab, but remaining third-party stock is available at reduced pricing.
The Carta 2 wins on speed (8 seconds vs. 38 seconds to heat), ease of use, and session flexibility. The Daab's 30-second auto session timer and multi-piece glass assembly create a steeper learning curve. Choose the Carta 2 for convenience, the Daab for terpene clarity.
Carta 2 vs. Focus V Carta Sport
The Carta Sport is now the current production model in Focus V's lineup following the Carta 2's discontinuation. It shares Intelli-Core atomizer compatibility and app connectivity, and costs less than the Carta 2 did at retail.
The Carta 2 had an edge with its built-in OLED temperature display (the Sport requires the app for readout) and on-device precision control. The Sport counters with a larger 2700 mAh battery (up to 50 sessions per charge vs. 11), IPX4 water resistance, and the removable CARTA CONNECT airpath that makes daily cleaning far easier. For anyone shopping the Focus V ecosystem today, the Carta Sport is the device to buy.
Who should buy the Focus V Carta 2
Cloud chasers on a mid-range budget who want thick, water-filtered vapor from an eRig that heats in 8 seconds and costs less than flagship alternatives.
App-savvy dabbers who want to fine-tune temperature profiles, save session presets, and receive firmware updates over Bluetooth.
Daily users who value battery endurance, since 11 sessions per charge with pass-through charging keeps sessions going without downtime.
VapeExperts verdict on the Focus V Carta 2
The Focus V Carta 2 earns its place as a capable mid-range eRig with fast heat-up, genuine temperature precision, and smooth water-filtered vapor. VapeExperts recommends it for concentrate users who want app control and thick clouds without flagship pricing.
Atomizer longevity and build quality inconsistency prevent a stronger recommendation. Budget for replacement atomizers every 3-6 months, and handle the glass with care.
