Just used this battery to jump start my car, worked as it should but the battery was dead instantly after. Charged it up completely and used it to charge my phone to not even half full and now the battery is already at 50% charge only (from 4 to 2 lights in an hour or so)... impossible if it actually had 21800mah, as my phone is only 4000mah... Don't know if it's an error in this specific battery or common issue.
