Each year I install thousands of outdoor holiday lights, including lighting the tree on our neighborhood entryway. But holiday lights can be a challenge. From which lights are best to where and how to arrange them for the most festive look. Worse yet, what if you want to install in an area that doesn’t have access to power? That’s where this holiday hack comes in to help you install lights outside in an area with no power.

Put up Holiday Lights & Plug into Battery Power Source

  • Plug lights into inverter via an extension cord.
    Note: You can directly plug lights into inverter if you don't mind the bin next to your lights, but I'd recommend using extension cord.

Charge Battery as needed

  • Depending on how many lights you use, you'll need to charge your battery.
    I charge mine nightly since my display runs 3000+ lights.

How can I run Christmas lights without an outlet? Use this Holiday Hack!

I recommend using an inverter as outlined in this blog post. For other ways to power lights without a battery, check out Michael Bluejay’s blog post on Battery Christmas Lights, I learned a lot about electricity best practices.

Which Christmas lights are the best?

Use LEDs when using a batter because they dray FAR LESS power than incandescent. They’re a little pricier up front, but are more cost-effective in the long run saving you money on your electric bill.

      Hi Blake – I can run 3000 LED’s for anywhere from 2-5 hours depending on how cold it gets and how how charged the battery is. Good luck and send me a pic if you do this!
