Default Stoker DC power from USB cable?

I need to be able to power a Stoker and 5cfm fan from a battery for a max of 12-14 hours. The battery must be portable to go to a campsite where a car can't be parked.

The Stoker runs off 5v DC. The power supply is a wall wart that converts 120v AC to 5v DC. It appears that the 12v DC adapter that Rocks sells for the Stoker is actually a 12v DC to 120v AC inverter and you just plug the wall wart into. That seems like an inefficient way to provide 5v of DC.

I would like to use a 12v battery like you would get at Tractor Supply to power a deer feeder.



I've got a 12v cigarette lighter jack soldered into spade plugs that slip onto the + and - terminals of the battery.



Soooo... it seems to me that a USB cable plugged into a cigarette lighter adapter would convert the 12v battery to 5v like what the Stoker needs.

I was thinking I could cut one end off of the USB cable and solder on a plug that would go into the back of the Stoker.

Has anyone tried this? Anyone have another solution for providing a power cable to a Stoker that can be used with a 12v battery? Or, has anyone used the 12v to 120v AC inverter with a battery like I described? I just need the ability to run a Stoker and 5cfm fan from a battery for 12-14 hours.

what is the amp rating on both?

I dont think the usb adapter would supply the amps that the stoker fan needs to run

but I could be wrong

The wall wart for my non-wifi stoker is 2.5 amps and the belkin charger is only rated at 1 amp. I would think this would work like a champ.

I ordered one. Is it an issue that it outputs at 5 amps and the Stoker input says 2 amps? Or will the Stoker only pull the amperage it needs?

This is what I used in the past before getting a power station for my birthday.
