Sparks Overland 4kW Portable Mini Gasoline Heater

High-output heat. Quiet operation. Built the Sparks way.

After more than two years of development, testing, and refinement, the Sparks Overland 4kW Gasoline Heater delivers higher-output gasoline heat for larger spaces and colder conditions — while maintaining the quiet operation, low power draw, and refined control that define our heater platform.

This is a Sparks-spec heater platform, built to our requirements and paired with our hand-assembled stainless enclosure and premium components — engineered to perform where it matters most: in the field.

Designed for overlanding, camping, rooftop tents, vans, trailers, and off-grid travel, this heater provides powerful, clean-burning gasoline heat with modern electronics, Bluetooth control, and stable operation — without the complexity or cost of professional OEM systems.

This model serves as our high-output gasoline option, ideal for customers who need more heat without stepping into expedition-grade pricing.

Why Sparks Overland?

Built the Right Way — Inside & Out

Real Metal Fuel Tank

No plastic. Ever. Our sealed, pressure-vented stainless steel fuel tank is safer, stronger, and built for long-term use in harsh environments.

Gasoline-Optimized Fuel System

Designed specifically for gasoline operation with quality fuel lines and filtration to ensure clean combustion, easy starting, and long service life.

A Sparks-Developed Heater Platform

This heater platform is the result of two years of real-world testing and refinement. By developing our own core system, we maintain full control over performance, reliability, and long-term support.

Quiet, Refined Operation

A tuned metering pump and smooth fan control dramatically reduce ticking noise and vibration — making this one of the quietest high-output gasoline heaters available for camping and overland use.

Modern Electronics & Bluetooth Control

Built-in Bluetooth connectivity allows full heater control through a mobile app. Adjust temperature, monitor operation, and manage output directly from your phone — without leaving your sleeping setup.

Premium Components Only

Stainless exhaust with muffler, sealed electrical connectors, quality fuel lines, and carefully selected hardware throughout — built for durability, not cost cutting.

Fresh Air Combustion Design

All combustion air is drawn from outside the unit. No fumes, no odors, and no shared cabin air.
