Focus V Carta Sport vs Puffco Proxy: Powerhouse Meets Design Rig
What is this matchup about?
Away from Puffco’s Peak class, the real portable race happens here: compact e-rigs under 250 euros that you actually carry around. Focus V enters the ring with the Carta Sport (2025), the athletic edition of its Carta line — trimmed on frills, upgraded on battery and heating speed. Puffco answers with the Proxy, a modular rig shaped like a pipe whose core module drops into different glass attachments.
Both heat conductively, both come with an app and water filtration. The decision is made elsewhere — and the data shows pretty clearly where.

Three rows decide this duel: heat-up time, battery and warranty. The rest is a matter of taste — and that is exactly what we look at next.
Heat-up and battery: the Carta Sport pulls ahead
10 seconds versus 30 — when it comes to heating, the Carta Sport plays in a different league. For a conductive portable rig that is a remarkable figure, making spontaneous sessions possible without the wait. The Proxy takes three times as long, which is bearable in daily use but hard to ignore in a direct comparison.
The battery makes it even clearer: the Carta Sport packs 2700 mAh, exactly double the Proxy’s 1350 mAh. On top of that, the Focus V supports passthrough charging — you can keep your session going with the cable plugged in, so battery level loses its sting. With the Proxy, an empty battery means: break time. Anyone planning long evenings or several rounds has found their winner here.

Design and ecosystem: the Proxy’s case
So why pick the Proxy at all? Because it is built around a different idea. The actual tech unit is a compact module sitting inside the included glass pipe — and it drops just as easily into other attachments from the Puffco range. One device becomes several: pipe, bubbler or elaborate glass art, depending on the attachment.
The Proxy also weighs just 280 grams, while the Carta Sport brings a noticeably heftier 400 grams to the table. In the hand, the Proxy feels more like a fine pipe than a piece of tech — and for many, that is precisely its appeal.
Temperature and warranty: points for Puffco
On temperature, the Proxy reaches up to 315 °C while the Carta Sport tops out at 296 °C. Both cover the usual dabbing ranges; if you like running very hot, the Proxy gives you a bit more headroom.
The warranty gap is more pronounced: Puffco offers 2 years, Focus V only 1. For devices around 200 euros with a hard-working heating chamber, that is no side note — the second year of coverage is a tangible plus.

The verdict: which one should you buy?
Take the Carta Sport if performance per euro matters to you: 10-second heat-up, double the battery and passthrough charging make it the more practical everyday device — especially for long sessions and spur-of-the-moment rounds.
Take the Proxy if form, feel and expandability are your priorities: the modular pipe concept with its glass ecosystem, 120 grams less weight and the second year of warranty are its currency.

Daily Use and Practicality
In everyday use, heat-up time shapes your routine more than any spec sheet suggests. The Focus V Carta Sport reaches operating temperature in 10 seconds, while the Puffco Proxy needs 30 seconds. That difference adds up over weeks of daily sessions. Quick morning sessions before work favor the faster device; relaxed evening sessions make the gap irrelevant.
Consider your typical usage pattern. If you vaporize 3-5 times daily, a few seconds per session compound into meaningful time savings. If you have one session per evening, both devices serve equally well. The Focus V Carta Sport rewards impulsive, grab-and-go use. The Puffco Proxy rewards users who plan their sessions.
Build Quality and Materials
The Focus V Carta Sport: Well-built device with solid materials.
The Puffco Proxy: Well-built device with solid materials.
Water Pipe Compatibility
Both devices support water pipe use. Water filtration cools the vapor and makes higher temperatures more comfortable. WPA adapters (14mm and 18mm joints) are available for both the Focus V Carta Sport and Puffco Proxy. Combining a vaporizer with glass elevates the experience significantly.
Cleaning and Maintenance
Regular cleaning directly affects vapor flavor and device longevity. Both the Focus V Carta Sport and Puffco Proxy benefit from weekly isopropyl alcohol soaks of removable parts. Screens and seals are consumable items that should be replaced every few months for optimal performance. A basic cleaning kit consisting of isopropyl alcohol (90 percent or higher), cotton swabs, and pipe cleaners covers most devices.
A clean device delivers noticeably better flavor than a neglected one. Most flavor complaints in online forums trace back to insufficient cleaning rather than device limitations. Residue buildup narrows the vapor path, increases draw resistance, and adds a stale taste. Budget 10 minutes per week for maintenance and both devices will perform at their best for years. Deep cleaning every 2-4 weeks prevents hard-to-remove buildup and keeps the airflow unrestricted.
Long-Term Value and Durability
A vaporizer is a long-term investment. Beyond the purchase price, consider replacement parts, cleaning supplies, and eventual battery degradation. The Puffco Proxy has the longer warranty at 2 years versus 1 years for the Focus V Carta Sport.
The resale market for vaporizers is active. Well-maintained devices from reputable brands retain 50-70 percent of their original value after a year. Both the Focus V Carta Sport and Puffco Proxy hold their value well due to brand reputation and build quality. Buying a quality device upfront typically costs less than cycling through cheaper alternatives.
Community support also factors into long-term value. Devices with large user bases have better troubleshooting resources, aftermarket accessories, and replacement part availability. Both brands covered here have established communities that make ownership easier over the years.
