What if you're out in the wild, enjoying the great outdoors, but all you have is a can of ice beer and no portable fridge? How can you keep your brew cold without electricity or fuel? That’s where “eCool†comes in. Designed for outdoor enthusiasts, eCool is more than just a beer cooler—it's essentially a compact, eco-friendly refrigerator that doesn’t require power. It runs on the natural temperature of the earth, making it a low-carbon, environmentally friendly solution for keeping your drinks chilled.
The eCool has a vertical cylindrical design, standing 1.13 meters tall. Inside, it features a track-like mechanism that holds up to 24 cans of beer, one at a time. When in use, most of the unit is buried underground, allowing it to take advantage of the consistently cool subterranean temperature. A lid, similar to a beer bottle cap, sits on top and acts as an insulating cover to maintain the internal coldness. Inside the lid, there's a crank handle that allows you to rotate the track and retrieve a single can at a time—perfect for a slow, controlled drinking experience.
eCool can be set up at home or during camping trips. However, to install it properly, you’ll need to dig a hole about a meter deep, which means having a shovel on hand. Despite this small inconvenience, the system ensures your beer stays at a stable, cool temperature, preserving its flavor and quality. The effectiveness of eCool depends on the local climate, but it can reliably maintain a temperature around 10°C, even in moderate conditions.
Priced at $300 (approximately 1,840 RMB), eCool offers a unique blend of innovation and sustainability. While the product itself is impressive, you might also need to purchase a shovel separately—a small but practical addition for those planning to use it in the wild. Whether you're a casual camper or a dedicated outdoor lover, eCool could be the perfect companion for keeping your favorite drinks refreshingly cold, without relying on electricity or fossil fuels.
