## Product: Igloo 28 QT Electric Cooler
**Brand:** Igloo

The Igloo 28 QT Portable Electric Cooler uses thermoelectric cooling to keep your drinks and snacks chilled while it's plugged into a 12V DC power source, like your car's lighter. It cools about 36°F below the air temperature, which means no ice is needed—chances are you'll have more space for your stuff and it stays dry, too. 

However, this cooler doesn't do so well unplugged. Once you disconnect it from power, it starts to warm up to match the outside temperature. So, it works best if you've got it plugged in during those long road trips. 

Keep in mind that it doesn’t come with an [AC adapter](https://www.shopsavvy.com/redirect?url=https%3A%2F%2Fwww.amazon.com%2Fs%3Fk%3DAC%2Badapter%26tag%3Dssw.ans.tx-1-20) for home use, so you’d need to grab one separately if you plan on using it indoors. Our research indicated that some folks found buying an additional adapter was a bit of an inconvenience. 

From what we found, the cooler shines on the go, but without power, its cooling power takes a dive. If you're thinking of using it regularly indoors, an AC adapter could be a worthwhile investment for you. 

Overall, it's a solid choice if road trips are your jam, just remember to keep it powered for the best results.
