Скачать или смотреть Running a Camping Fridge on Tool Batteries - I Tested It

G'day, I'm Cahn. Lately I've seen people running a camping fridge on 18V tool batteries and it sounds good... especially if you already own a stack of them.

But how practical is it really?

In this video I compare running a camping fridge directly from a 12.8V LiFePO4 battery versus running it from an 18V tool battery through a 12V converter.

Everything is measured properly, no guessing.

I look at:

Energy capacity (watt-hours, not just amp-hours)

Voltage conversion losses

Real-world runtime

Battery swap frequency

Charging practicality

And overall cost...

The results? It works! But there’s around a 10% efficiency loss through the converter and you’ll be changing batteries roughly every 4 to 5 hours depending on conditions.

If you already own the tools, it can absolutely get you out of trouble for day trips or light use.

If you’re building a camping power system from scratch, a dedicated 12V lithium setup may make more sense long term.

As always, this is real-world testing... not theory!

Cheers!
