I bought this for home use but decided to take it to work to really test it, up in the oilsands of fort mcmurray alberta, i had a peterbilt 367 with a cummins X15 thats a 15litre diesel, the batteries where so dead the starter solenoid just clicked, I hooked up the GBX155 waited 30 seconds and it started like nothing and was still showing about half charge, I have been in the diesel trade over 20 years and have boosted hundreds of trucks and have never seen anything this compact and powerful, i highly recommend it
