Compact and easy to install, does a great job
Smaller than I expected but much easier to install because of its size. The mounting strap has two holes to install the plastic snap-on back to the metal of the vehicle inside the engine compartment using two self-tapping screws (provided). There are two lugs on the snap-on back that accommodate a velcro strap (also provided) which ties down the charger in addition to the snap-on back that is latched to the charger. A well thought out system to ensure that the charger cannot shake loose when the vehicle is moving. In my case I have attached the charger to the wall above the front passenger tire well of my Silverado truck. That way, the charging leads can easily reach the battery although the power lead is too short to go anywhere near the front grill (Maybe 2-3 ft long). My GFI socket is on the side of my garage, about 45ft away from the engine compartment but it's easy to run a 50ft outside-rated cable (SJTW 12/3) to the charger power cable under the hood. With the temperatures around 31 to 42 degrees F right now and a new battery I am able to keep the battery fully charged in a truck that sometimes sits on an outside concrete pad for 2-3 weeks at a time. I am very pleased with this product. It gives me piece of mind that I will always be able to crank my engine whatever the weather. It will also help me to prolong the battery life. I now own two NOCO chargers, both are able to condition a battery as well as charge it. My other NOCO charger is a NOCO GENIUS 10A waterproof marine charger which can be used for several different battery types and does a great job for my lawn tractor and 12v shed battery for LED lights. It can handle lithium batteries also which works for my kayak. My neighbors call me when they need help with charging because they now understand the problems caused by sulphates which NOCO battery chargers can deal with. NOCO make great products. I have no hesitation recommending them. (NOTE: I gave this 5 stars but only four lit up. The first one stayed empty).

Great buy. Works as outlined in add. Easy to install.
Saved me $400.00. Reconditioned my car battery that dealership told me, I needed to have my 14 month old replaced.
