Customer Ratings & Reviews

Since buying this Anker so ever frost two battery, I never have to worry about my cooler running out of battery. It charges up pretty quickly with my USB-C cable, and I like how it has four indicator lights so you can know approximately how much it is charged. You can also monitor the charging percentage on the Anker app. Another plus is that whenever I bring it out, people are pretty impressed by it and by the fact that I don’t need ice to keep the contents in the cooler cold. Definitely a conversation point at any function.

I can keep my drinks and food cold and also able to take ice cream with the cooler and still be able to charge my phone

The battery is actually pretty good. I felt like it could’ve been a little bit cheaper thus the four stars. I do have to say it feels pretty well-made though.

I picked up this extra battery to ensure the cooler keeps running uninterrupted during long days out. The 288Wh capacity delivers exactly as promised, maintaining a stable temperature without draining the vehicle's battery. The multiple charging inputs (AC, car, solar) make it incredibly versatile for off-grid use, whether parked at a lakefront rental or during a long drive. It functions exactly as I've come to expect from Anker products—dependable, well-engineered, and practically foolproof.

If you are using this while on the go the extra battery is a must, in Arizona with one compartment a freezer at 0 degrees and the other at 34 degrees battery lasts atleast 8 hours, havent checked exactly how long both batteries last but with the app it will tell you when battery is getting low when connected to Wi-Fi.

Great battery long lasting and charging is good, worked well on our 2 week vacation to Tennessee

Impressive battery life and the efficient cooling performance that keeps food and drinks chilled. I appreciate the fast charging speed, noting that it functions effectively without draining the vehicle's power. Overall, the product is highly regarded for its reliable performance and convenience.

Works as intended and can be used outside of the cooler its designed for.

Extended cooler life i can usually get two days with cooler

I love being able to use the battery to charge my phone. Being able to charge the battery without it being connected to the Everfrost 2 cooler is very convenient. The only negative thing i could say is it’s pricey, but worth it.

I am glad I purchased a 2nd battery, you never know when you will need to run off of battery power. It is supposed to last 4.3 days.

Can’t believe how long the power bank last almost 24 hours on a single charge sitting out side in 90 degree weather.

Works great definitely would recommend for cooler.

Very good battery, well spent money. Keep my drinks cold and a battery back for my devices as well

The battery worked as expected and I love the how long it lasts!

It works good but for me, my experience has been tuff with these batteries. Cause I cant charge it with a usb c. I forcefully have to charge it with the cooler. Not really reliable and efficient.

You need this if you plan on utilizing both sides of your fridge. Thank me later.

This item gets overheat at my first use then stop release power. i’m worried about it will burn, so i return it immediately.
