Stay Cool While Fishing: How to Build a Portable 5-Gallon Bucket Air Conditioner Powered by a Battery Brick
Fishing on a hot, windless day can be uncomfortable, but with a little ingenuity, you can create a portable air conditioner using a 5-gallon bucket, some ice, and a USB-powered fan. This DIY bucket AC can be powered by a battery brick, making it lightweight and easy to carry. It’s perfect for keeping you cool while you’re out on the water. Here’s how to build your own 5-gallon bucket air conditioner for those scorching, windless days.
Materials You’ll Need
5-Gallon Bucket with Lid: The main body of your air conditioner.
Frozen Gallon Jug or Ice Packs: A frozen gallon jug of water or several ice packs to cool the air. The water can be refrozen and reused for your next trip.
USB-Powered Fan: A small, energy-efficient fan that can be connected to a battery brick.
Battery Brick: A portable USB power bank to run the fan.
PVC Elbow Fittings: Two or three 2-inch PVC elbow fittings to direct the cool air out of the bucket.
Insulation Material (Optional): Foam or reflective insulation to help keep the ice from melting too quickly.
Drill and Hole Saw: For cutting holes in the bucket lid for the fan and PVC fittings.
Step-by-Step Instructions
Prepare the Bucket:
Place the 5-gallon bucket on a stable surface. Use a hole saw to cut two or three holes near the top of the bucket for the PVC elbow fittings. These holes will allow the cool air to escape.
Install the PVC Elbow Fittings:
Insert the PVC elbows into the holes, facing outward. This directs the air sideways, ensuring that the cool air spreads out horizontally. Secure them with adhesive if needed.
Prepare the Lid:
Drill a hole in the center of the bucket lid to fit the USB-powered fan. The fan should be positioned to blow air down into the bucket, forcing the cool air out through the PVC elbows. Attach the fan securely to the lid with screws or adhesive.
Add the Frozen Jug or Ice Packs:
Place the frozen gallon jug or ice packs at the bottom of the bucket. For better cooling efficiency, you can line the inside of the bucket with insulation material. Remember, the frozen jug can be refrozen and reused, making this an eco-friendly solution.
Connect the Fan to the Battery Brick:
Plug the USB fan into the battery brick. Make sure the battery brick is fully charged before heading out. Depending on its capacity, the battery should keep the fan running for several hours.
Assemble and Test:
Place the lid with the fan onto the bucket, ensuring it’s sealed tightly. Turn on the fan, and you should feel cool air blowing out of the PVC elbows. The air passing over the ice will cool down and be pushed out, creating a portable AC effect.
Take Your Bucket AC with You:
With its lightweight design, this DIY air conditioner is easy to carry to your fishing spot. Position it nearby, with the PVC elbows directed toward your sitting area. As long as the ice remains frozen, the bucket AC will keep you cool.
Why Use a Battery Brick?
Portability: Battery bricks are lightweight and easy to carry, making them ideal for outdoor activities like fishing. They eliminate the need for heavy batteries or complicated setups.
Rechargeability: You can easily recharge a battery brick, and many models offer multiple charges for your devices. This means you can power your fan multiple times during an extended fishing trip.
Versatility: A battery brick can be used for more than just powering your fan. It can also charge your phone, GPS, or other small electronics while you’re out on the water.
Tips for Maximizing Cooling Efficiency
Use Reflective Insulation: Lining the bucket with reflective insulation can help keep the ice from melting too quickly, extending the cooling time.
Freeze Saltwater: For longer-lasting ice, consider freezing saltwater, which stays colder longer than regular water.
Multiple Battery Bricks: If you’re fishing all day, bring an extra battery brick or a portable solar charger to ensure your fan stays powered.
Final Thoughts
Building a 5-gallon bucket air conditioner powered by a battery brick is a practical, lightweight solution for staying cool while fishing. It’s easy to make, portable, and doesn’t require a lot of space or complicated parts. Best of all, you can refreeze the water in your gallon jug and reuse it for your next trip, making this setup both cost-effective and eco-friendly.
Try out this DIY project on your next trip and enjoy a cool breeze no matter where you are!
