Just looked it up. Bought it for 10 bucks from side deal in early february. I probably used it 10 or 15 times. It’s a nice format as it slips into a pocket easily, though it is a bit heavy at 10,000 milliamp hours. Seems to charge rapidly from both the USB A and C ports. Most of the time it gets chucked in my backpack when traveling. Gets used to top off the tablet or phone on the plane or in the rental if the usb is crappy!
