Engel 40L Fridge Powerbox
Looking for a simple, portable way to power your Engel 40L fridge without installing a permanent dual battery system in every vehicle? The Visor Investment Engel 40L Fridge Powerbox is designed to give you a complete, organised and portable fridge power solution for your ute, 4WD, touring rig, work vehicle or camping setup.
If you regularly change vehicles, you know how frustrating it can be to invest in a quality dual battery system only to leave the battery, charger and wiring behind when you sell or upgrade your ute. The Visor Investment Fridge Powerbox provides a practical alternative by combining the auxiliary battery, DC-DC charger, fridge connection and electrical accessories into one purpose-built aluminium enclosure.
Designed to suit an Engel 40L fridge in its transit bag, this powerbox gives you a dedicated home for your fridge while providing integrated auxiliary power. Simply move the powerbox with your fridge and take your power system with you when you change vehicles.
Built from CNC cut and folded aluminium, the Visor Investment Engel 40L Fridge Powerbox is lightweight, strong and designed for the demands of touring and outdoor use. The standard textured black powder-coated finish gives it a rugged appearance, while custom colours are available upon request for those wanting a more personalised setup.
Portable Fridge Power Solution
The biggest advantage of the Engel 40L Fridge Powerbox is its portability.
Traditional dual battery systems are generally installed directly into the vehicle. While this can be an excellent solution for a long-term vehicle build, it becomes less practical when you frequently change vehicles.
With the Visor Investment powerbox, your auxiliary battery and charging system are contained within the box itself. This means you can take your power system with you rather than leaving your expensive electrical equipment installed in your old ute.
It is an ideal solution for people who:
- Frequently change vehicles
- Want to avoid permanent dual battery installations
- Run an Engel 40L fridge while touring
- Want a portable camping power system
- Move a fridge between multiple vehicles
- Use a ute for both work and recreational purposes
- Want a cleaner and more organised fridge setup
The powerbox can be particularly useful for touring, camping, fishing, remote travel and 4WD adventures where reliable portable refrigeration is essential.
Designed for the Engel 40L Fridge
The Visor Investment Engel 40L Fridge Powerbox is designed to suit an Engel 40L fridge in its transit bag.
The enclosure provides a dedicated space for your fridge while incorporating the electrical equipment required to provide auxiliary power. This creates a more integrated solution than simply carrying a portable fridge and separate battery box.
Before ordering, please confirm that your Engel fridge and transit bag configuration is compatible with the powerbox.
Integrated Lithium Battery and DC-DC Charger
The powerbox comes with an integrated lithium auxiliary battery and DC-DC charging system.
The base model includes a 135Ah Lion Lithium battery with a 3-year warranty and a Redarc 25A DC charger.
This provides a convenient auxiliary power source for your Engel fridge while travelling. The integrated design keeps the major electrical components together inside the powerbox rather than spreading them throughout your vehicle.
The DC-DC charger allows the auxiliary battery to be charged from the vehicle’s starting battery while driving.
For customers wanting increased charging capacity, a Redarc 40A DC charger is available as an upgrade.
For information about Redarc vehicle charging and dual battery products, customers can visit the official Redarc website.
CNC Cut and Folded Aluminium Construction
The Visor Investment Engel 40L Fridge Powerbox is manufactured using CNC cut and folded aluminium.
The aluminium construction keeps the enclosure lightweight while providing the strength and durability required for regular use in touring, camping and vehicle applications.
The panels are CNC cut for accuracy and folded to create the structure of the box. This construction method provides a clean appearance while keeping weight under control.
For a touring vehicle, weight is always an important consideration. By using aluminium rather than unnecessarily heavy materials, the powerbox provides a strong enclosure without adding excessive weight to your setup.
Durable Powder-Coated Finish
The standard finish is a durable textured black powder coat.
The black finish gives the powerbox a rugged appearance that works well with modern utes, 4WDs, canopies, trailers and touring accessories.
Custom colours are also available upon request. If you want your powerbox to match your vehicle or existing accessories, contact Visor Investment to discuss available options.
Lockable Lid
The Engel 40L Fridge Powerbox features a lockable lid to help protect your fridge and electrical equipment.
Your fridge, lithium battery and charging equipment can represent a significant investment, particularly when you’re travelling remotely or leaving your vehicle unattended.
The lockable lid provides an additional layer of security by helping restrict access to the contents of the enclosure.
The lock is intended as an additional security feature and should not be considered theft-proof. Appropriate vehicle security should still be used whenever valuable equipment is left unattended.
Gas Struts for Easy Opening
Accessing your fridge should be quick and convenient.
The powerbox is fitted with gas struts to assist with opening the lid. The struts help support the lid when open, making it easier to access your Engel 40L fridge during everyday use.
Whether you’re grabbing a cold drink at camp, loading food before a trip or checking your supplies, the gas-assisted lid makes accessing the fridge simple.
Drop-Down Front Panel
A drop-down front panel provides convenient access to the electrical components and fuses.
This feature also makes installing and removing the fridge easier, giving you better access to the area around the fridge without having to completely dismantle the powerbox.
Easy access to the fuses is also useful when checking or servicing the electrical system.

The Visor Investment Engel 40L Fridge Powerbox base model includes:
- 135Ah Lion Lithium battery

Available Upgrade Options
The Visor Investment Engel 40L Fridge Powerbox can also be upgraded to suit your individual requirements.
Wiring Kit for DIY Installation
A wiring kit is available for customers who want to complete their own installation and connect the powerbox to the vehicle’s main starting battery.
Enerdrive Btec 100Ah Battery
The standard Lion Lithium battery can be upgraded to an Enerdrive Btec 100Ah battery, which comes with a 5-year warranty.
Redarc 40A DC Charger
For increased charging capability, the standard Redarc 25A DC charger can be upgraded to a Redarc 40A DC charger.
Additional 12V Outlet
An additional 12V accessory outlet can be added to the powerbox.
You can choose between a USB outlet or cigarette-style 12V socket. Please specify your preferred option when ordering.
Rear Solar Input
A red solar input plug can be mounted to the rear of the powerbox. This provides an additional option for connecting compatible solar charging equipment to your auxiliary battery system.
Internal Door Light
An internal door light is also available as an upgrade. This makes accessing the fridge and electrical components easier when camping or working around the vehicle at night.
Ideal for Utes, 4WDs and Touring
The Engel 40L Fridge Powerbox is designed for customers who want a practical and portable power solution.
It is suitable for:
- Ute touring setups
- 4WD touring
- Camping
- Fishing
- Overlanding
- Remote travel
- Work vehicles
- Service vehicles
- Canopy builds
- Camper setups
- Trailer setups
- Weekend adventures
- Long-distance touring
Because the power system is contained within the box, it can be moved between vehicles rather than permanently installed into one particular vehicle.
A Cleaner Fridge Setup
The Visor Investment Engel 40L Fridge Powerbox helps keep your fridge and electrical equipment together in one organised package.
Instead of having a fridge, battery, charger and wiring spread throughout the rear of your ute, the powerbox provides a dedicated enclosure for the system.
This can help create a cleaner and more professional-looking touring setup while making your equipment easier to transport.
Built for Customers Who Change Vehicles
If you have ever sold a ute with a quality dual battery system installed, you’ll understand the advantage of having a portable power solution.
The Engel 40L Fridge Powerbox is designed to move with you.
When you change vehicles, your fridge, auxiliary battery and charging system can move with the powerbox. This makes it a particularly useful option for people who regularly upgrade their vehicles or don’t want to permanently modify their new vehicle.
Customise Your Powerbox
Every touring setup is different, which is why Visor Investment offers several upgrade options.
From battery and charger upgrades to additional outlets, solar input and an internal light, you can configure the powerbox around your requirements.
Custom powder-coated colours are also available upon request.
If you have a specific electrical requirement or customisation in mind, please contact us before ordering so we can discuss the available options.
