Query: good shop booster pack

This is a great booster pack. I own an auto repair shop and these packs get put to the test. This is a no frills pack. that is better for what we use them for. It does not have an air pump or fancy light. It has good CCA power to start even the toughest trucks. we have jumped several dual battery diesel trucks with these packs. (I have two) I like the charger on these packs too if using an extension cord it does not seem to over charge the pack. The cables are nice and long and have nice clamps. the only thing that i would change on this pack would be to lengthen the cables a little bit so they are not as tight storing the clamps on the top. when putting the clamps back to store it often marks up the cables and i have a small cut in the ground cable now. But i also use my packs sometimes up to 4 and 5 times a day in the winter. this is a great pack you will not be disappointed.
