I purchased this battery jump starter to use for my motorcycle. It’s lightweight and small size makes it easy to fit in my tool bag that’s attached to my motorcycle.It is not recommended to jump start a motorcycle with a car battery so having this with me gives me piece of mind that I’ll never be stuck with a dead battery again.I tested it on a drained motorcycle battery and hooking up the negative and positive cables to the battery was very easy and the teeth on the cable clamps gripped the terminals tightly. I was able to start the motorcycle in less than a minute after hooking the jumper to the battery. It also has a voltage meter that tells you the voltage of the battery and a flashlight which are excellent features.The whole unit fits in a zippered semi-soft carry case which keeps it snug and safe.You can also use the unit to charge your cellphone or other items in an emergency.I now carry this back and forth between my car and motorcycle so it’s always with me.
