The Geek Bar CLR 50K is the first Geek Bar you can actually see through. That sounds like a gimmick until you realize every other 50K-puff device forces you to guess how much liquid is left. The CLR puts a transparent tank front and center, pairs it with an LED status display, and wraps the whole thing in a familiar all-in-one disposable format. No detachable parts, no pod swapping — just a straightforward high-capacity device with the one feature every vaper has been asking for: visibility.
The CLR 50K nails the transparency concept better than any competitor. Real-time liquid monitoring eliminates guesswork, the dual-mode system works exactly as advertised, and the 14-flavor lineup covers every major profile. Where it falls short: the flavor count is modest compared to Pulse X's 46+, and there's no third power mode like the Clio's Super Pulse. But if you want a no-fuss, all-in-one 50K device where you always know exactly where you stand — this is it.
What Makes the CLR Different
CLR stands for Constant Liquid Regulation — Geek Bar's system for maintaining consistent vapor output even as the tank empties. In practice, this means you don't get that weak, burnt-tasting final 10% that plagues most high-puff devices. The flavor stays stable until the tank is genuinely empty.
But the real differentiator is the transparent tank. This is the first Geek Bar where you can physically see the e-liquid level without relying solely on a screen estimate. Combined with the LED display showing battery percentage and current mode, you have full situational awareness at all times.
The adjustable airflow is another upgrade over earlier Geek Bar models. You can tighten the draw for a mouth-to-lung feel or open it up for a looser, direct-lung style. Most disposables lock you into one airflow setting — the CLR gives you a dial.

Dual Mode Breakdown
Like every modern Geek Bar, the CLR runs two power modes:
Lower wattage, smoother draw. Optimized for maximum efficiency — this is where the 50K number lives. Flavor is clean but muted compared to Pulse. Best for all-day, low-intensity use.
Higher wattage, warmer vapor, more pronounced flavor. Burns through liquid roughly 2× faster, but the flavor payoff is significant. Best for shorter sessions when you want maximum taste.
The numbers tell the story: Normal Mode stretches the device to its maximum lifespan, while Pulse Mode cuts that in half but delivers noticeably richer flavor. Most users will switch between the two depending on the situation — Normal during work hours, Pulse when they want to actually taste what they're vaping.
All 14 CLR 50K Flavors

Who Should Buy the CLR 50K
Want maximum puff count without the complexity of a modular system. Hate guessing when your device will die. Prefer a traditional all-in-one form factor. Like customizing your draw with adjustable airflow. Are happy choosing from a focused flavor menu.
Want to swap flavors without replacing the device. Need a third power mode (Super Pulse) for maximum vapor. Prefer a larger battery (1,400mAh vs 900mAh). Want dual 360° screens. Don't mind a higher upfront cost for a reusable base.
