    Takes forever to charge. Literally tried to charge it before a storm and it never reached 100.

    These are great for charging devices, especially during power outages - very common around here. I use them all the time and recharge on my solar generator so my power usage for rechargables is free! This 30K version has many more charges than my original 20K version. The 30K version will charge 100 ecigs, 7 to 10 iPhone charges, 2-3 Macbook Air charges. A small and easy way to be ready when the supercells hit.

    This power bank is a powerhouse. It's a little heavy, however I'd keep it in my car to back up charge, phones, Bluetooth speakers
