Introduction

We built this USB electric heater for engineers who are squeezed for space but still need serious, focused heat. It’s a quartz halogen heater, designed to give you direct, pinpoint warmth. Think of it as a tiny powerhouse that delivers steady heat without taking up much room.

What Makes It Tick

Let’s get into the guts of it. The core is a 300mm quartz tube, and it packs a serious punch at 2500W. It runs on 400V, not your standard wall outlet voltage. Here’s the why: higher voltage means more power without needing to crank up the current. That keeps the wiring thinner and stops voltage from dropping off over distance. And that 300mm length? It gives you a predictable, even spread of heat across a specific zone.
