VapeExperts Review of the Focus V Carta Sport
The Focus V Carta Sport is the most affordable eRig with Bluetooth app control and firmware updates we've tested, as of May 2026. It carries over the Intelli-Core atomizer platform from Focus V's Carta 2, meaning existing Focus V users can swap their chambers directly onto this lower-priced unit.
You get 15-second heat-up, water filtration through borosilicate glass, and a companion app for temperature customization at a price that undercuts most app-enabled competitors. The trade-offs are real: build quality and on-device controls lag behind what you'll find from rivals without smart features at similar pricing.
The Carta Sport is a solid budget entry into concentrate dabbing with water filtration. Not a stripped-down compromise, but not without weaknesses either.
What you get in the box
The kit includes the Carta Sport base, a borosilicate glass top, one Intelli-Core atomizer, the CARTA CONNECT removable airpath, a USB-C cable, spare silicone gaskets, and a water-resistant carrying case. That carrying case is sturdy enough to protect the glass top inside a backpack, a welcome inclusion at this price point.
320 g aluminum and silicone body feels grippy, not refined
The Carta Sport weighs 320 g and measures 140 × 64 × 64 mm, making it compact for a water-filtered eRig. The body pairs an aluminum core with a silicone outer shell that provides real grip, even with damp hands.
Focus V replaced traditional buttons with a "Control Stick," a small joystick-style input for navigating presets and powering on. It takes a session or two to build muscle memory, but the tactile feedback feels more deliberate than cycling through button presses.
The borosilicate glass top locks on securely and provides water filtration. No metal or plastic contacts the vapor path between the atomizer and your lips, keeping the flavor path clean.
Build quality is the Carta Sport's weakest aspect in our testing. The silicone-over-aluminum body feels functional rather than polished, and the glass demands careful handling during transport. IPX4 water resistance protects against splashes and light rain, a useful addition for a device that lives near water sources.
Quartz chamber heats in 15 seconds with water-filtered vapor
The Carta Sport uses conduction heating through Focus V's Intelli-Core atomizer, which houses a quartz chamber holding roughly 0.08 g of concentrate. Heat-up takes 15 seconds from cold.
Whether you own the Focus V Carta Sport 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.
Without the companion app, you cycle through 5 temperature presets via the Control Stick. The app unlocks finer adjustments, which makes a noticeable difference when dialing in low-temp flavor runs versus high-temp cloud production.
Water filtration through the glass top smooths each draw considerably. Draw resistance is moderate, rewarding a slow, steady pull rather than a deep lung inhale. The glass vapor path keeps flavor clean at lower settings where terpenes come through most clearly. For more on how temperature affects flavor and effects, check our temperature guide.
Adding terp pearls and an aftermarket carb cap transforms the experience. Multiple users confirm these two accessories improve vapor density and concentrate vaporization efficiency. If you pick up a Carta Sport, budget for both.
Vapor density at higher presets satisfies cloud chasers, though it doesn't match the thicker output from Focus V's pricier models with larger chambers. The 0.08 g capacity keeps individual dabs modest, so heavy users will reload more often than they'd like.
2700 mAh battery powers up to 50 dabs per charge
The Carta Sport runs a non-replaceable 2700 mAh battery, a 35% capacity increase over the Carta 2's cell.
Focus V rates the Sport at up to 50 dabs per charge, and user reports range from 29 to 50 depending on temperature and session length. Your results will shift based on which preset you favor and how long each heat cycle runs. For tips on maximizing runtime, see our battery guide.
Full charge takes about 90 minutes from empty via USB-C. Pass-through charging means you can dab while plugged in, so the Carta Sport never forces you to wait.
Removable airpath makes cleaning genuinely easy
Loading follows standard eRig workflow: lift the glass top and carb cap, drop concentrate into the quartz chamber, replace the cap, and fire. Our complete dabbing guide covers technique for beginners.
Cleaning is where the Carta Sport earns real points. The CARTA CONNECT removable airpath pulls out for separate cleaning or swapping with a fresh one. No other eRig at this price bracket offers this feature.
After each dab, a quick Q-tip swab of the chamber while still warm keeps flavor fresh. For deeper maintenance, disassemble the glass, atomizer, and airpath, then soak in isopropyl alcohol. Our eRig cleaning guide covers the full routine.
The Intelli-Core atomizer is cross-compatible with the Focus V Carta 27.8. One user logged over 1,500 dabs on a single atomizer without replacement, a strong showing compared to eRigs that need new coils every few months.
Bluetooth app unlocks the temperature control this device lacks on its own
Without the app, the Carta Sport operates on 5 presets identified only by LED color. Functional, but you rely on memory to know which preset is active. Connect over Bluetooth and you gain precise temperature adjustment, LED customization, and firmware updates that can improve the device after purchase.
This is the Carta Sport's defining advantage over both the Puffco New Peak7.5 and Bomb eRig Aerix7.5, neither of which offers app connectivity. Firmware updates mean the Sport can gain features over time, and the temperature granularity lets you fine-tune for specific live resin or rosin profiles.
The downside is tangible: no built-in temperature display anywhere on the device. Without your phone, you're guessing which preset you're on. That's a real usability gap during quick sessions where your phone isn't within arm's reach.
How it compares to other budget eRigs
Carta Sport vs. Focus V Carta 2
The Carta 2 was the Carta Sport's direct upgrade within Focus V's lineup before its discontinuation in July 2025 (pulled per a Puffco patent settlement). It heats in 8 seconds (vs. the Sport's 15), includes a built-in OLED display for real-time temperature readout, and delivers 1°C precision across 232-371°C. Its larger chamber handles bigger loads, and the overall build feels more refined.
The Sport counters with a larger 2700 mAh battery (vs. the Carta 2's 2000 mAh), budget-friendly pricing, and the same Intelli-Core cross-compatibility. If you already own Carta 2 atomizers, the Sport accepts them directly. For anyone considering a Carta 2 from remaining third-party stock, the Sport offers better battery life and easier maintenance at a lower price, while the Carta 2 wins on display and temperature precision. Our full Carta 2 vs. Carta Sport breakdown covers every spec difference.
Focus V has announced the Carta 3 as the Carta 2's true flagship successor. Until it ships, the Sport is the only current-production Focus V eRig.
Carta Sport vs. Puffco New Peak
The Puffco New Peak costs less and heats faster (10 seconds vs. the Sport's 15). Build quality feels more polished, and Puffco's 3D chamber heats evenly without aftermarket accessories. It runs 4 fixed presets with no app, prioritizing simplicity over customization.
The Sport fires back with Bluetooth app control, firmware updates, temperature customization, and a larger battery (2700 mAh vs. 1300 mAh, roughly 50 dabs vs. 35). For users who want to dial in specific temperatures for different concentrates, that's a meaningful advantage. The New Peak wins on simplicity, heat-up speed, and build polish; the Sport wins on customization and endurance.
Carta Sport vs. Bomb eRig Aerix
The Bomb eRig Aerix undercuts the Carta Sport on price while offering faster heat-up (5 seconds) and 1-degree temperature precision with a physical display. Its 22 mm ceramic 3D chamber distributes heat more evenly, and the detachable airpath matches the Sport's cleaning convenience.
The Carta Sport's edge is Bluetooth connectivity and firmware updates. If app control and future-proofing matter, the Sport is the only pick under mid-range pricing. If faster heat-up, precise on-device control, and a lower cost matter more, the Aerix outperforms on raw specs per dollar.
Who should buy the Focus V Carta Sport
App-first concentrate users who want Bluetooth temperature control and firmware updates without mid-range spending. No other eRig at this price delivers connected features.
Existing Focus V owners who need a travel or backup rig. Intelli-Core cross-compatibility means sharing atomizers between the Sport and other Focus V eRigs.
First-time eRig buyers stepping up from dab pens or traditional rigs. The 15-second heat-up, Control Stick, and removable airpath keep the learning curve manageable.
VapeExperts verdict: solid value if app control is your priority
The Focus V Carta Sport earns its place as a capable entry-level eRig with smart features that punch above its price bracket. App connectivity, firmware updates, and Intelli-Core cross-compatibility create a functional edge over budget competitors that lack any connected features.
Build quality and the lack of an on-device display prevent a stronger recommendation. VapeExperts recommends it for concentrate users who rank app control and battery endurance above build refinement. Check our best concentrate vaporizers ranking for alternatives if your priorities differ.
