Coolbox is a heavy duty smart toolbox loaded with features. Its removable and rechargeable Lithium Polymer battery powers built-in 40w bluetooth speakers, a digital clock, super bright LED floodlights, and 2 USB ports to charge your devices. You can also plug the Coolbox in with its 10 foot retractable power cord, and it features 3 electrical sockets so you can run corded electric tools through the box. Just under the lid is a 20 x 12” dry erase whiteboard so you can always be ready to sketch out design ideas or keep notes on your project. Coolbox is water resistant and has a generous 1797 cubic inch capacity, so it can hold plenty of tools. The side mounted wheels make rolling the box painless even when fully loaded with up to 65 pounds of gear. The magnetic lid makes it easy to keep track of screws, nails, nuts and bolts and other small parts. Coolbox also has an often critical tool, a bottle opener. With a full charge the battery can provide 5 hours of audio play time, 10 hours of USB charging, and 80 hours of illumination for the powerful built-in floodlights. Seasoned entrepreneurs Mike D’Agostini and Christopher Engelo launched Coolbox on IndieGoGo where they raised more than $350k of their $50,000 goal in March 2015.
