The Charge 3 JBL speaker sounds awesome, and plays loud to fill outdoor parties with excellent sounding tunes. Thus, as we’ll discover in the JBL Charge 3 specs below, it features noticeably more bass response than models in the JBL Flip family. So this is a definite upgrade from Flip.
Plus, even when playing at top volume, the built-in rechargeable battery lasts up to twenty hours per recharge.

So in our view, the most intriguing feature: you can charge your cell phone, tablet, or other mobile device right from this speaker’s 6000 milliamp hour battery.
But while we only got a twenty percent raise in our iPad Air’s battery percentage before the battery in this speaker went dead, this was enough to finish what we were doing on the tablet. Indeed, it’s nice having the emergency bank of power along for the ride when you carry around the JBL Charge 3 Bluetooth speaker.
