Is it worth considering?
The Quasar OS25000 hits a sweet spot for me. It’s simple, strong, and way more advanced than it looks. You get legit flavor density, a reliable draw, and that signature Lost Mary throat kick thanks to the triple mesh coil setup. It’s also one of the more compact high-capacity vapes I’ve tested. Perfect for vapers who want no-fuss performance that still feels premium.

How it performed
What stood out in testing
Pros
- What I Loved Triple Mesh Coil =
- Big Flavor Each puff is dense and full-bodied. It honestly feels closer to a pod system than a traditional disposable — the vapor is thick, and flavors hit hard.
- Power Modes for the Win You can toggle between three output levels, maxing out at 25W. I ran it on mid most of the time for balance, but Boost Mode was great for more intense sessions.
- LED Animated Display It’s subtle but helpful; you can see battery status, power level, and general puff status without needing to guess.
- Strong Nicotine Hit At 5% nic salt, this thing kicks. Definitely one for the nicotine lovers out there — you’ll feel it.
- Good for On-the-Go Despite its power and puff count, it’s pocket-sized, light, and draw-activated. Zero setup. Just hit and go.
- Things to Keep In Mind Flavor May Fade Slightly Late-Game A couple flavors started strong and softened up after a week — not bad, but noticeable.
- Battery Life Varies Heavy users may need more frequent top-ups, especially in Boost Mode.
