The Wi AudioStream EL power source’s flexible design boasts an
internal rechargeable battery for 4~6 hours of battery operation. The
optional ON-THE-GO AA battery power adapter provides for 10~13
hours of extended battery operations and the AC power adapter
provides continuous operation, so there’s no need to power down the
Wi AudioStream EL for recharging or swapping the AA batteries on
the optional ON-THE-GO battery power booster. The Transmitter and
Receiver can also be powered by USB bus power when connected to
any USB host equipped device for continuous power operation.
