Does this require a certain minimum draw to prevent itself from turning off like other packs? When using the usb port?

I bought and used mine a whole week on a backcountry Hiking trip in Colorado, and it DOES turn off all the time no matter what device it is charging… iPhone, iPad, other. I want to like this unit but it is VERY annoying because it shuts itself off long before charging the device, and it has plenty of life left in the battery pack. I’ve found that the only way to “reset” this unit to continue charging is to briefly plug it into its AC charging cord and then It’s good to go. If this is how it works, my review is going to be 2 stars. I was actually logging in to Amazon to ask the seller about this issue, when I saw your question and wanted you to know from a Buyer and not from the seller.

Size of WHAT? The small capacity battery or the large capacity battery? Jerry answered for the large battery, Talentcell answered for the small battery.

How clean is the 12v power? Is it suitable for running headphone amps that are sensitive to noise on their DC input?

Please use our YB1203000 without Usb output,I think that model is more clean

The 12 volt output is not regulated; is the 5 V usb output regulated, to power arduino?

The voltage was regulated down to 5 volts so yes it is regulated
