Why Portable Power Units Are Useful
Sometimes, when installing outdoor LED lights, you might find that:
The only available power source is on a timer or not working
You’re at a residential site and the owners are away
You need to test lights before repairs are done
Lights have been damaged or corroded during storage
Having a portable power unit means you can test and install your lights, no matter the situation.
Option 1: Prebuilt Portable Power Inverter
What it is: A plug-and-play portable power station, often found at hardware stores (like Canadian Tire) or online.
How to use: Plug your lights or extension cord directly into the unit, turn it on, and your lights should work.
Pros: Compact and light, easy to use.
Cons: May not be waterproof
Option 2: DIY Car Battery + Inverter Setup
What you need:
A 12-volt car battery
An inverter (at least 450W with a resettable circuit breaker)
A rolling toolbox with a lid (for easy transport and rain protection)
Extension cord
How to set up:
Place both the battery and inverter in the toolbox.
Cut small holes in the side of the box for the extension cord and ventilation.
Attach the inverter’s red (positive) cable to the battery’s red terminal, and the black (negative) cable to the black terminal.
Plug your lights or extension cord into the inverter.
Turn the inverter on—your lights should work!
Why this is great:
Durable and safe for outdoor use when protected in the toolbox
Flexible power for both small and large installations
Stays protected from rain and is easy to move
Tips for Best Performance
Always charge your portable power units fully before each job—ideally overnight.
Test your lights using the portable unit before installing, to catch any issues early.
Both of the above solutions work for residential and commercial jobs.
