We used the battery for 3 days with our Setpower 34 quart. We used it during the day on the road driving and it kept everything frozen. We charged each night.

The design is the best I've seen for this size. Would buy again.

I have tried coolers like this in the past and have been severely disappointed. This product has exceeded my expectations. The build quality, cooling efficiency, light weight, and the capacity of this product have been more than impressive. I am ordering another one. Well done Set Power!

Been with me on over 15k miles of trips over the last 3 years and still works like a charm!

I love my cooler I'm living in a homeless shelter on ssi fixed income and I'm disabled and homeless

Finally got out for a 5 day camping trip and the Setpower 27 qt fridge worked flawlessly. It maintained a steady temp of 37 degree inspite of ambient temp of 97-100 degrees. I run it off a Yeti 300 in conjunction with a 200 W solar panel which was albe to keep up as long as we had sunshine.

The best protective equipment for for your cooler!

Both the Fridge and the Battery are excellent products.

This is absolutely the best "cooler" I have ever had. When you pair it with the battery and cover it becomes the brand you will ever buy!

Runs quiet, keeps very cool. Nice unit. Using it inside the home for a family member to keep certain items cold.

It's good

So far only been a couple weeks but running good so far

We love our DT55 cooler. It’s so nice to not be having to go buy ice every few days. And we can have to separate temperature zones if we want. It’s no heavier than a good quality cooler so it’s very portable.

So far my DT55 is functioning well. Just like my older unit which has performed flawlessly for 5 years.
