Is the 9V plug center-positive or center-negative?

Dear Sir,Thanks for your question.9V plug is center positive.Best Regards,

Can the unit be charged and used at the same time?

Dear Rand,Thanks for your question.Yes this battery can be charged and used at the same time.Best Regards,Rome JiaTalentCell Technology.

can the 9v supply and the 12 v supply be used at the same time to power one device that needs 9v and one that uses 12v?

Absolutely 100% confirmed. I have mine powering a 15" monitor from the 12V port and Intel Compute Stick on the 9V port (with step down converter to 5V) simultaneously with no problem. Works like a champ, I love this thing! It comes with a splitter cable so you can plug it into the wall charger and use it at the same time from the 12V port. Get yourself some 2.1mm X 5.5mm adapters and you'll be able to power anything you want simultaneously from the 12V & 9V ports.

thanks. one more question- can you power a 9v device and a 12 v device at the same time??

Dear Steve,yes our battery can power a 9v device and a 12v device at the same time.
