NoCo builds some good stuff....I personally do not own one of these Jump Box's yet.....But NoCo is the only onboard battery charger I will use or recommend for Marine use....There is a LOT of Junk marine chargers out there and they are name brand.....Back to the jump Box.....I understand that these late model cars are having problems when using jumper cables and screwing up electronics on the vehicle used to jump with.....This makes these Jump Boxs even more valuable
