Alternate power for my bass guitar pedal board to avoid the 60 Hz hum of wall warts.

Got tired of hearing the 60 Hz hum from my pedals when using wall warts for power. Has a 9v DC output as well as 12v DC output. Also has a 5v USB out for charging cell phones, etc. NOTICE: the output cable is +9v on the center pin, and as most guitar pedals use -9v on the center pin, I also purchased a polarity reversing cable to get the -9v output. (Mr.Power Reverse Polarity Converter Cable 5.5 X 2.1 For Keyboard Guitar Effect Pedal) -- Works great and NO hum ! :)

Bought this to lighten my pack from current 3lb battery to the 1lb talentcell. Using a DC cord for my Phillips dreamstation with no heated tubing or heated humidification I got the following times over 4 nights at home: 6.4hrs, 5.7hrs, 6.7hrs and 3.3hrs in the 4th night before it shut off with the cpap reading low voltage. My average pressure was 8.5 over this period. This well surpassed my expectations of hoping for 2 nights on the trail. Outdoor temperatures may affect the performance but I''m confident I can get 2 nights of cpap use while backpacking.
