Very effective. Very portable.

Saved me many times, very reliable. Shopping experience was satisfactory, work was done smoothly. Powerful, compact and extremely reliable. Absolutely worth the price. Saves time and effort, has excellent effect, is durable enough, and the car immediately resumed normal operation. This is a very practical vehicle tool, small, lightweight and compact.

This is the second time I have bought one of these. I have used it to jump start my riding lawnmower. Very handy to have and easy enough for an elderly woman to use!!
