The z2 Mini, despite what some videos claim, runs on 15 volts. Most 12 volt batteries (I often use a Rockpals unit but Goal Zero and others are similar) produce a little over 12 volts and will power it for a bit but soon run out of power. I ordered a $15 12-15 volt converter (in no electrical engineer, it’s a little box that makes 12 volt into 15 volt) from Amazon and soldered it between a 12 volt cigarette lighter plug and the machine. Now my 280 Amp hour pack will run it for 5 or 6 nights. I have no idea how long a regular deep cycle battery would last but I’d think a couple of weeks..
I just ordered a 160 amp hour battery from Amazon for $35 which should last several days and weighs 4 lbs.
My very basic calculations seem to say that batteries shouldn’t last that long but I think that it only draws maximum wattage when you are breathing out (against it) and so it actually only draws about 1/2 the amperage.
Long story short for a Z2 Mini converter a 12V battery to 15V and it last a long long time.
