My analysis of this portable power product showed that it is a must-have in every car owner's emergency kit .The alligator clips are powerful and easily attach to battery terminals ensuring a quick jump start in any situation. The compact size and lightweight design make it easy to store in the trunk or glove compartment. However, it does require an external power source to work, so be sure to have a backup battery or charger on hand. Overall, I highly recommend the XINCOL Starter Connector for all automotive emergencies..
