URB 3g Empty Device | Your Cart, Your Rules

This is the URB 3g empty. Think of it as a reliable, no-nonsense piece of hardware. It’s a solid, refillable cart built for folks who know what they want and don’t want any surprises. You pick the oil, you control the hit. It’s that simple.

Capacity & Compatibility: Holds a full 3 grams. It’s threaded to work perfectly with URB’s own Gasline and Sticki Rosin syringes—a matched set. You can load it with your preferred thick oil or distillate. The top pops off for a clean fill, no messing with tiny ports.

Specs & Performance

This isn’t a one-setting wonder. It’s got three voltage levels, clearly marked. Treat it like a trigger:

• 3.0V (Low): For flavor. Preserves the terpenes, gives you a smooth, tasteful pull.
• 3.3V (Medium): Balanced. Good vapor, decent flavor. The all-around setting.
• 3.5V (High): For clouds. A stronger, more substantial hit when you need it.

It also has a 1.8V preheat function. Hit the button twice to warm up thicker concentrates. Prevents clogs, ensures a smooth first draw every time. No waiting.

Build & Reliability

The body is compact and pocket-friendly. No sharp edges, just a discreet cylinder that gets the job done. It charges via USB-C—plug it in with your phone, and it’s ready fast. The battery life is substantial for a device this size.

Controls are straightforward: five clicks on/off, three clicks to cycle heat settings. No confusing menus. If you’ve used a vape battery before, you already know how to run this.

Price: $16.49

This is a workhorse device. If you’re tired of disposables and want a durable cart you can fill with your chosen extract, this is it. Grab it, fill it, and go.
