Review on Jump-Start Your Car With Ease: Portable 2000A Battery Booster For Gas And Diesel Engines, 20000MAh Power Pack, USB Quick Charge 3.0, And LED Light by Josh Nat

This jump starter has one major drawback. The manual says you have 30 seconds after connecting before it automatically disconnects itself, but I bought two of these and both only gave me between 7 and 8 seconds to attempt to start my car. Needless to say 7 to 8 seconds is not long enough to walk around to the drivers door, get in get in and attempt to start it. This is a major flaw! Nearly impossible for one person to use successfully!
