I have had my Noco for over a year and finally had to use it today. My model of car is notorious for being a battery-drainer and I knew there would come a day I needed it. It is Christmas Eve and today was the day that I found a dead battery (of course, on a day I am not about to go get a new battery) but it was exactly zero problem because this Noco had me up and running in mere seconds with an instant start!
It holds a charge a long, LONG time and I have only freshened up the charge every 4 months or so, whether it needed it or not since I hadn't used it. Even before I needed it I was impressed enough to give one to each of my adult daughters this Christmas and now I have 100% confidence that if they are ever stuck they can get going immediately! No more stringing jumper cables between stranger's cars on a dark night, no trying to remember the order of connection between cars, no fear of just getting out there and doing it themselves. Everyone should have one of these in their emergency roadside kit!
