Low Power Consump�on
24 hours Playback
Extremely Low Power Consump�on
The JAB series could offer playback �me up to 24 hours con�nuously, which
was tested with Bluetooth connected and Jazz style songs playing back
con�nuously. The maximum output voltage on the speaker is 4V RMS and the
duty is no less than 5%.
Sure Electronics also offers a solu�on with the con�nuous playback �me up to
60 hours, which is more than 2 days with only 2 hours quick charge. This
version can only provide a 7.5Wa�s maximum output at 4ohm loads, but that
is already enough for most applica�ons.
Thanks to engineers’ delicate design of power management circuit and reliable
components employed in JAB1/2, its power consump�on is extreme low,
ensuring the high efficiency and long standby �me. When powered by ba�ery
board, the quiescent current is only 2mA, meanwhile, the standby current is
only 2.9mA with SD short to GND and only low power module available when
connected with 19V power adapter. (The specific value of power consump�on
changes to different model. For more specifica�ons on power consump�on,
please refer to the manual of JAB1/2.)
