Purchased to use as a 5v + 9v power supply but it's not suited for that purpose. Testing device draws 180mA so expected run-time is 53 hrs @ 80% power conversion efficiency. Battery supplied power for only 32hrs meaning this battery is only 5760mAh. Battery turns off unless connected device is drawing +100mA, so not suited for low-power devices.
It was not tested as a JumpStarter so it may work fine for that use (adding a star for this).
