Review on Rechargeable 12V 11000MAh 9V 14500MAh 5V 26400MAh DC Output Lithium-Ion Battery Pack For LED Strip, CCTV Camera, Portable Li-Ion Power Bank With AC/DC Charger - Black by Chad Jeffries

I was looking for a way to make my Blackmagic ATEM Mini Pro portable. This works great. I bought the 1100Mah version and it came with both the 2.1x5.5mm cable and the 2.5x5.5mm 9v cable. I used the second cable (in reverse) in the 12v socket to power the ATEM Mini Pro. Works like a champ so far but I haven’t had time to test the run time or reliability. So far, I’m very happy and I’ll update my review if I get less than 3 hours of runtime or have ANY issues with it. This is a tiny investment to make this a truly portable 4-way 4K switcher/recorder!
