The first time I cranked this Mighty Max MM-H5, I was surprised at how quickly it fired up my car on a chilly morning. I barely had to turn the key twice before the engine roared to life, even after sitting overnight in the cold.

It feels sturdy in your hand, with a solid weight that promises durability.
