The Coolest blender is powered by an 20 volt rechargeable battery and currently chews through a pitcher of margaritas in about 15 seconds. The pitcher is a very hard BPA-free plastic (not glass!) that should be close to unbreakable, so no worries at the pool or beaches. You should get about 16 pitchers of cocktails from a single charge of the main battery.
To give you an idea of the testing we do on the blender motor, we blend pitcher after pitcher of our Abuse Recipe with very little time to rest in between. Only if every single motor can successfully blend 384 pitchers without failure or fuss, AND THEN DO THAT AGAIN, will we deem this motor Coolest-worthy.
