[CPAP] Off-grid power supply for camping/hiking?
#1
Question 
love camping, but I have sleep apnea, and use a CPAP.
I do take it camping, but in doing so, away from any AC power supply I have to bring a huge deep cycle battery, which isn't all that portable friendly.

The battery is heavy and hard to lug around, and well, not all that backpack or hiking friendly.

So with that said I am looking for a smaller, lighter fix or replacement for the heavy deep cycle battery.

I know I could go out and buy a travel cpap and a couple of the smaller batteries that goes with them, but I am on a budget and CPAP's are not cheap, much less the small traveling ones and batteries.

So my questions is, how do I figure out how much power my current CPAP uses, and how small of a battery I can get away with using.
Ideally the battery should be good for 2 nights of sleep without recharging.

My CPAP is the Phillips Resperonics Remstar system 1, and the air pressure is nearly maxed out on it at 18cm.

I was looking at the Suaoki 220Wh Portable Generator Power Supply on [commercial web address to Amazon site removed], and was sort of wondering if it would work to power the CPAP for a couple of nights without recharging.

Any help in figuring this out would be great, Thanks.

Look on Amazon for the Poweradd Pilot Pro 32000 mAh li-ion power bank. It has an output capacity of 12-volt 5.4 amps and has been demonstrated on running CPAP units up to 2-1/2 + days. Due to limits in peak capacity, it is best to start the Remstar CPAP in ramp and you cannot use the humidifier. It even includes a power tip that works with your machine.
