Included in the box are the GB251 24V UltraSafe Lithium Jump Starter, 56W XGC power adapter, four interchangeable AC cords (Australia, Europe, North America, United Kingdom), XGC extension cables, and a Max Protection EVA Case. Backed by a 1-year limited warranty and engineered in the USA, the GB251 is the ultimate professional-grade solution when failure is not an option.

Review: Love it! - It's been a rough winter in North Dakota. Freezing temperatures left our truck batteries not wanting to hold a charge. This is heaven sent! No more waiting all day to jump them off of our pick up trucks battery. This works very quickly but one jump and you have to recharge it. It takes about 3 hours to fully charge. We use it for our 2015 Pete 579. It fits nicely in it's case and it's not as heavy as I expected it to be.
