The media could not be loaded. Just wow! I was spring cleaning and got to my car. It had been sitting over winter and the battery fully died so I would have needed help. This thing is AMAZING!!! Sadly, I couldn’t capture it correctly since I had started it already, but I wanted to show how quick it works. I showed in the video that my car lights weren’t even turning on (shows just how dead the battery was). How the device is supposed to work is how it did in the video. Originally I was a special case. When I hooked up the cables, the lights didn’t cycle. If you are connected properly, hold the (!) button to override the safety and try starting now. That is what I had to originally do. If in the other case like in the video, the battery is dead but not entirely drained so it works as intended. I used it a few times getting the video properly and it still has 4bars (full battery). I appreciate how small and portable the device is. You could almost mistake it for a regular power brick if it weren’t for the text on the device. Overall, I would purchase it again, but I doubt I will ever need to. It will probably outlive me!My unit didn’t come with instructions so I had to look them up… Here is what to do in detail:1) Check if car will start without help2) If car won’t start, open hood of vehicle3) Take NOCO jumper and attach jumper adapter to device4) Connect clamps to car battery terminals, black-to-black and red-to-red (order doesn’t matter since the clamps are not powered yet)5) Turn the NOCO device on6) The white light below the power indication bar should turn solid and the power indicator lights should start to cycle6.5.1) If the clamps are connected properly and the previous step didn’t happen (power lights stayed solid and no white light), then either you didn’t connect properly or the battery is below 2v (completely dead). In this case you need to override the unit to force to start the process. Hold the (!) button for a few seconds6.5.2) The white light previously mentioned will flash instead of stay solid and the power indicator lights will cycle7) Attempt to start vehicle7.5.1) Vehicle should start without delay. If it doesn’t, your battery’s terminals might have corrosion on them interfering with the connection of the device. Power off the device and remove the clamps, in that order7.5.2) Clean the corrosion off the battery’s terminals7.5.3) Start again from step 48) Let the vehicle stay on to charge battery.9) Turn off the NOCO and remove the clamps, in that order10) Store NOCO device as desired, preferably in its included drawstring pouch and in a cool, dry location11) Either drive the vehicle for a while or turn the vehicle off after some time to save up some battery charge for later
