Superior quality and excellent workmanship. This cooler is perfect for storing small amounts of drinks, food, or other vegetables/snacks, suitable for short or long day trips. We first used it on a trip, alternating between the car's 12V power supply (3-4 hours at a time) and household AC power (using the optional adapter), and also when visiting relatives and friends along the way. All items remained cool from morning to night.

I bought this product on a friend's recommendation. It's a compact and stylish personal cooler/insulated box, perfect for a family day trip. It's very lightweight and portable. I recently took it to the beach. Its cooling function might not be enough to chill room-temperature drinks to ice-cold (unless you're driving long distances), but it's great for keeping drinks chilled in the car or even longer. As other reviewers have mentioned, this cooler only comes with a car power adapter. While a standard power outlet would be better, I don't think a car power adapter is necessary considering that most destinations (beach, outdoor parties, parks, etc.) may not have power outlets.

I bought this in case of a power outage. This way I can keep medicine, a few bottles of drinks, or coffee creamer chilled. It's really useful; you just plug it into the car and it works.

I chose this cooler because it's compact and affordable. It also comes with two cup holders. Its performance perfectly matches the advertising.

I tested the heating function before setting off, and it worked well, but I didn't use it because I have a 12-volt heating cup that can even make frozen soup.

This cooler can also hold some larger bottles if you lay them flat and stack them. It keeps things warm for a while after the heat is off. My tip is to cover it with a lid to insulate it from direct sunlight. Be careful not to block the exhaust fan.

I really love this cooler.

I bought this to visit my son at university; it was an 11-hour drive. I needed to take some medications that required refrigeration, and this refrigerator solved that problem perfectly. It's very quiet and plugs directly into the charger in the back of the car. Throughout the trip, it not only kept the medications cold but also kept several bottles of drinks fresh. It's affordable and doesn't create a mess like ice cubes. I'll definitely buy another one.
