Is ColdFlare reusable?
**Absolutely. ColdFlare e-flares are built for multiple and long-term use: buy it once, use it again and again. Just refill the liquid, charge the battery, and you're good to go.**
Is ColdFlare dangerous?
Nein – absolut nicht. Bei sachgemäßem Gebrauch ist ColdFlare sicher und stellt keine Gefahr dar. Bei den verwendeten Technologien gibt es keine explosive Reaktion, keine offene Flamme und keinen unkontrollierbaren Funkenflug. Es besteht bei normaler Handhabung keine Verbrennungs- oder Brandgefahr für dich oder umstehende Personen. Auch das Liquid ist gesundheitlich völlig unbedenklich.Wie bei jedem technischen Gerät mit einem leistungsstarken Lithium-Ionen-Akku sollten jedoch die üblichen Sicherheits- und Ladehinweise beachtet werden.
When will ColdFlare hit the market?
**We are doing everything we can to bring ColdFlare e-flares to market as quickly as possible. However, because we refuse to compromise on quality and must ensure all required safety certifications and regulatory approvals are fully in place, this development demands both time and precision. Our current roadmap targets late 2026 for the first production run, with full-scale mass production rolling out in the course of 2027.**
What is the runtime of the device?
The exact specifications are still being finalized, but a single battery charge and full tank are engineered to easily cover the demands of typical use at sports events, concerts, festivals, or choreographies.
Which colors can be set?
Thanks to the integrated RGB LEDs, basically any color across the entire RGB spectrum can be displayed. You can easily switch between preset colors directly on the device—and later down the line, right from our smartphone app.
How does ColdFlare create the visual effect?
nside the ColdFlare e-flare, a specialized liquid is heated and expelled as thick vapor. High-powered RGB LEDs instantly illuminate this dense cloud—producing a vibrant light and smoke effect that captures the raw visual energy of a traditional flare, completely free of any chemical combustion.
Is there a risk of burns when using it?
No, don't worry. While localized heat is generated inside the device during the vaporization process, the outer casing is designed to stay relatively cool and safe to hold. Because there is no pyrotechnic reaction or combustion, there are no flying sparks and no open flames.
How often can I use ColdFlare?
Basically, as often as you want. ColdFlare is a high-end electronic device featuring a rechargeable battery and a refillable tank. You buy it once and use it over and over again—just like your smartphone.
Are there any wear-and-tear parts on the device?
Yes, just like with any electronic device, ColdFlare includes components subject to natural wear and tear.
The atomizer head (coil): Because it continuously heats and vaporizes liquid, performance will naturally decrease over time. The coil needs to be replaced periodically to guarantee maximum vapor output. We engineered the system so you can swap it out yourself in just a few simple steps—inexpensively and hassle-free.
The battery: Just like your smartphone or power bank, the built-in lithium-ion battery has a finite lifespan and will gradually lose capacity over years of charging cycles. When the time comes, you can easily order a replacement ColdFlare battery and swap it in yourself.
What kind of liquid is used to fill ColdFlare?
The device must be operated exclusively with original ColdFlare liquid. Using water, standard vape liquids, or any other substances can cause irreversible damage to the heating unit—and potentially the device itself—and will void your warranty. But don't worry: our original ColdFlare liquid is reasonably priced, so there's zero reason to cut corners or experiment.
Is the liquid used dangerous?
No, the ColdFlare liquid is completely harmless. The vapor produced is entirely non-toxic, non-irritating to the respiratory tract, and leaves zero harmful residue behind. Unlike genuine pyro smoke, which can release toxic gases and dangerous particulates, inhaling ColdFlare vapor during normal use is completely safe for your health.**
Is the device ready to use right out of the box?
Almost! Before your first session, all you need to do is fully charge the battery and fill the tank with the included ColdFlare liquid. Simple step-by-step instructions are included with every starter pack.
What effects are possible, and is there an app control?
At launch, the device features built-in dynamic modes—such as an intense strobe effect—to unleash the full visual power of the dense vapor. Down the line, the system goes fully digital: We’re launching a free companion app that lets you dial in custom light effects, color transitions, and precise timing sequences. This allows you to choreograph entire shows down to the second and trigger them with a single tap.
