The long-awaited Prime Day is finally here. If you're looking to upgrade your current Bluetooth speakers, now is the time to buy.

For a limited time, Amazon has reduced the price of the JBL Boombox to $279, $120 off the regular asking price. That's a great speaker for the price.

The JBL Boombox delivers premium sound with two bass radiators and four active transducers, promising "the strongest bass" and "monstrous sound." But power and audio are only part of the equation, because portability makes or breaks a Bluetooth speaker.

Thankfully, the JBL Boombox has a rugged design, is IPX7 waterproof, and weighs only 2.4 pounds. Most importantly, however, it is powered by a 20,000 mAh battery that promises 24 hours of battery life. That means it provides enough power to last all day, and by the time you're done using it, the phone will still be charged.
