Here we list details about the battery inside the JBL Xtreme 3 power bank Bluetooth speaker, including capacity, dimensions, mAh value and play time.
Furthermore, the mAh or milliamp-hour value tells us how long the battery will supply sufficient power based on amount of current drawn from it. Explicitly, the mAh figure tells us how many amps the battery will provide for one hour.
Plus, using some math (ratios), you can also gather from this number how long the battery will last for any amount of current drawn from it. E.g. If you double the amount of current, you halve the play time. E.g. If you draw two (2) amps, a one amp-hour battery will last for thirty (30) minutes or 1/2 hour. Thus, this is why playing the speaker very loud lessens the Xtreme 3 play time per charge. Also, if you cut the current by half, then you double the playing time per charge. E.g. If you draw just half (1/2) an amp, our hypothetical one amp-hour battery will last for double the time, or two (2) hours. Finally, this is why playing the speaker softly lengthens the time it can run per recharge.
