Ok. I checked out the pocket juice. It's perfect for size but it plugs into the wall to charge. Big downer for what I need it for.bobsalmon wrote: ↑Fri Apr 06, 2018 4:00 pmI use my RPI 3 daily and is fully portable.
I use a "PocketJuice", dual USB port with an off/on switch, 8000maH. Available from Amazon for $8 on sale. It comes with a 3" USB cable.
It will run the Pi all day and better than any laptop that I am aware.
My screen is powered separately by a 11.1V Li-Po battery.
That's just speculation until I do my tests. You may be right or wrong but one thing is for sure, less with age is correct.Imperf3kt wrote: ↑Tue May 15, 2018 9:39 pmNote that 8000mAh will take between 4 and 16 hours to charge, depending on the power supply charging it and the circuitry inside the powerbank.
8000mAh will most certainly not run a Pi and a screen for two days.
I expect around 7 hours when brand new, less with age.
That powerbank does not sound capable of your needs.
