JOMGAND JQ3500 Jump Starter 3500 Amp 24000mAh Car Starter for up to 10.0L Gas and 8.5L Diesel Engines with 100W Two-Way Fast Charging, 12V Lithium Portable Battery Booster Pack with Smart LED Display Review

This spins over Duramax when the starter would only click, no hesitation at all.
This is a must have for every driver out there. Think of it as jumper cables but you do not need a second vehicle.

A very handy tool to have in the car in the event the battery is dead and the car won't start. Far easier then trying to bother someone for a jump start.

This also acts as a great emergency terminal and can be used to charge electronics (via USB or USB-C) if ever lost somewhere or in a storm. Has a GREAT powerful built-in flashlight as well.

Car will not start? Don't worry with this compact car jump starter you will have what you need to get going again.
