It can start 6.0 L gas/3.0 L diesel engines and other 12 V vehicles like motorcycles, cars, SUVs, pickups, or lawnmowers.

How often does it need to recharged?
This product has a maximum standby time of 18 months, but it's best to charge it within 3 months to maintain battery health and extend its lifespan.
What is the battery capacity?
The battery capacity is 37WH.
Why did the jump starter fail to jumpstart my truck in winter?
The battery may not perform optimally in extreme cold weather. Please ensure that the jump starter is kept in a warmer place before use.
