Coolest gadgets to kick off summer

Some coolers just keep your beers from getting warm. The Coolest Cooler has loftier aspirations. The $400 summer accessory has a Bluetooth speaker, USB phone charger, a cutting board and built-in blender. Powered by a rechargeable 20 volt battery, the Coolest Cooler will make you popular at any beach or campground, especially if bring enough ice for the margaritas.

Update: Coolest Cooler has received criticism for not shipping products to around 20,000 of its Kickstarter backers. The company raised $13 million on the crowdfunding platform in 2014 but says the product cost more to make than it expected. It says it is currently working to fund more Kickstarter orders through new sales.
