They exaplain what is "always on feature" and then they say after 20 minutes it will shut itself down. is 20 minutes = always?

Hello, Thank you for reaching out. Our apologies for the confusion - the battery does not arrive in our "Always On" function, but rather in the standard "Auto Off" function, which turns off after 20 minutes of inactivity. If you wish to put the battery in "Always On", simply hold down the power button for 5 seconds - the battery's LEDs will blink 3 times to signify it has been switched from "Auto Off" to "Always On".

Will it output the full amount of current (2.1A + 1A) while pass through charging?

We are seeing 0.95 and 2.05A with both ports activated. Note that we only recommend the 2.1A port for use in solar applications.

Would a 6v solar panel charge the battery?

Not sure, it was purchased to charge a cell phone.

has anyone hook this up to a solar charger and leave it on 24/7? will it cause a fire?

In additional to the quality of the battery itself, this battery has a variety of protections (Short Circuit, Over Charge, Over Discharge, Over Current, Over Temperature) so that it can be safely charged 24/7.
