like: work as intended I am satisfied with using this device but not sure if my time was limited how handy this particular device
dislike: the plastic on the red clip feel out as I open the box will not charge a totally dead battery not sure how long will this last
note: doing repair on cars may cause some manufacturer warranty to be voided also weather condition was cold and snowing. could had been a 5 star but I had issue with this device stated in dislike. the clamps were too big to connect to the battery terminals (this is my major issue)
My battery was a duralast gold 75-DLG, I had no idea what type this is so I set this device to "standard". 1. battery was dead and this device does not acknowledge that the clamps were connected so I connected a 12v 3a power source and let it charge for a couple of hours. 2. after disconnected everything and connect this device. the "charge" did not work so I pressed the recondition, left at that point for 3 hours. 3. turn the power off and on. pressed the "charge" button. the indicator said "60%". left it overnight. 4. I came back in the morning and check the device condition, it was off. my MMV indicated a charge of almost 13v. car started with no issue.
Added note: the red clamp will not clip on positive terminal. The black will sometimes slip off the battery black terminal.
