How long does the battery charge in a Celestron PowerTank Lithium PRO last

I am not a professional, I am an amateur astronomer, so this is a real world account of the Celestron PowerTank Lithium PRO (18768-CGL), this is my second, I started with its little brother, but I needed a longer lasting telescope power pack due to me doing solar day time and astronomy at night at a dark site where I can't charge anything as there is no mains supply, it is twice the size of its little brother, but it's still a lot lighter than a lead acid battery and will out-power it. It's a major upgrade on its little brother (Celestron PowerTank Lithium) as it has 2 USB's and a 1x 2.5 mm centre live plug for your telescope, so it's the same plug for the Celestron and Skywatcher mounts and a cigarette plug socket which can all be used at the same time, it's little brother you can only use one socket at a time.
The power level is 4 red lights, so you can see what is going on, on its little brother you have to turn it off to see battery level but not with this lithium pro. The instructions say the light flash in sequence they do on its little brother but not on the lithium pro press The battery button once to see power level when once press again, and it now powered up battery lights on USB lights on, press and hold the button, and it will turn it off.
So to sum up if you need power for your telescope this is a must-have item it can be used for more than astronomy, fishing at night, camping, run a cool box.
