JUMBO 22,400 mAh Dual USB PowerPack 2 pk

Does anyone have any experience with this brand?

How does it compare to the other offer?

For the love of god, can anyone make a high capacity battery bank with external DC input other than a micro-usb cable? Seriously, 22,500mah at 1A will take (roughly) 22.5 hours to fully recharge!

I have been looking for one with a standard barrel connector to support 2-5A charging for a long time now and I’m convinced they just don’t exist. The batteries can take it so I know that isn’t the issue.
