Hello,

 

 I am having a hard time figuring out what to do when I want to take my equipment out into the field (All is fine when I can simply plug in my mount at home). Currently I have a Celestron Power Tank Lithium LiFePO4 that I had planned on powering my AVX mount and Asiair/ZWO 120 mini guide camera. However I realized that the usb ports are only 2.1 amps and the Asiair requires 2.5 amps. I am kind of at loss of what to do? Should I go and get the Pegasus power box, a second Celestron Power Tank, or some other solution? 

 

              Thanks

The most effective solution is to buy a tractor battery which is half the size of a regular car battery. You will have at least 30ah which will get you over 10 hours of use. Recharge the battery while you drive home by using your cigarette plug in. You can buy a cigarette female plug with clips to connect to the battery and use the cable that came with your AVX to power the mount. Get a male cigarette plug with clips to recharge on the way home. This can be done for under $75.

The ASIair comes with a 12v-to-5v DC converter for this exact scenario.  Just use a 5.5.x2.1 splitter and cable (and/or extension if you need).

 

The PowerTank is plenty.  The links above are provided as examples, search on Amazon for specific lengths to customize the perfect cable system for your gear.

The Asiair only requires 2.5a if you are drawing 500ma from all four of its ports. I'd expect that the device itself reqiures only around 500ma and the rest of the power is for the usb ports. With one device plugged in that is drawing power from a port, i'd expect it to draw only 1a.
