Protect your portable generator—and your peace and quiet—with the Hudson Generator Quiet Box. Designed for durability, noise control, and all-weather protection, this premium aluminum enclosure helps your generator run safely and discreetly in a wide range of environments.

Constructed from heavy-duty aluminum, the quiet box offers exceptional strength while remaining lighter than many comparable storage options, making it easier to install, move, and maintain.

At the same time, louvered ventilation panels and an integrated cooling fan promote efficient airflow, preventing heat buildup and supporting safe, extended run times.

Beyond noise reduction, the Hudson Generator Quiet Box is designed to guard against the elements and the unexpected. It shields your generator from rain, snow, freezing temperatures, and high winds, while its reinforced structure helps deter wildlife such as squirrels and rodents from damaging wiring.

  1. Hudson Generator Stealth Box

    After very extensive searches to find a portable generator outdoor storage box. There simply aren’t a lot of choices on the market. The idea of retrofitting a resin storage shed or wood shed, and the work involved in doing this type of project just wasn’t a good choice.
    The Hudson Stealth Box was a perfect fit for my Champion Tri Fuel 10K Portable Generator.
    Plenty of interior space to allow for cooling air flow of the unit while it is running. The louvered side panels are real nice feature which keeps rain from entering the interior. It comes with insulated sides and top which does cut down the decibels while running.
    The unit allowed me to free up space in my garage, keep the generator where I need it in an emergency and stop hauling around a heavy generator through snow and over grass just to get it in place.
    It comes extremely well packaged to protect it from damage caused by delivery companies.
    If you’re looking for an affordable, quality built generator enclosure thIs one is by far worth your time.
    Its size and height makes it a nice landscape fit as well, so it doesn’t look like a huge box sitting out in the yard.
    I highly recommend The Hudson Stealth Box.

Customer Questions
What generators will this storage box work with?
This box is designed to fit a wide range of portable generators, including inverter models such as the Hudson R4000iep (4,750 W gas starting) and similar-sized units. The maximum size of generator that can be placed in the box is 39.4" x 32" x 31.7". Always check your generator’s dimensions before purchase.
Can I run my generator while it’s inside the box?
Yes. The storage box includes louvers and ventilation features to promote airflow and help prevent overheating during operation. Always follow safe operating practices and manufacturer guidelines to avoid heat build-up or exhaust issues.
Can I easily access my generator’s controls and fuel tank?
Most models of portable generators can be accessed for refueling and controls without fully removing them from inside the cover, assuming the generator fits comfortably inside.
Will it reduce generator noise?
Yes — the box includes fire-resistant sound-absorbing material in the front and side panels, which helps lower the noise output for a quieter operation. This can be especially valuable in residential settings or around campsites.
What are the placement requirements for the generator storage box?
The box should be placed on a solid, level surface that can support at least 440 lbs (200 kg). A stable foundation helps ensure safe operation, proper airflow, and long-term durability.
Does the storage box require an electrical connection?
Yes. The built-in heat exchange fan is powered by a standard 115V AC electrical connection. This fan helps improve airflow and temperature control when the generator is operating.
