373-P1 Heavy Duty Jump Starter

Qingdao Donjelion International Trade Co., Ltd. is one of the most credible manufacturers and suppliers of 373-p1 heavy duty jump starter in China. If you're going to buy customized 373-p1 heavy duty jump starter, welcome to get more information from our factory. Good service and quality products are available.

373-P1 Heavy Duty Jump Starter is engineered for operators who cannot afford starting failure. It combines high discharge lithium technology with intelligent power management to deliver consistent cranking power for diesel and gasoline engines.

Unlike standard portable boosters, this model is optimized for heavy load vehicles up to 560 horsepower, making it suitable for long haul logistics, construction fleets, and agricultural equipment. Its dual voltage 12V and 24V system allows one device to support an entire mixed fleet.

1. Reliable Cold Start at -40°C

Cold weather is one of the biggest causes of battery failure. The 373-P1 uses vehicle grade 60C high rate cells that maintain stable discharge even in extreme cold. This ensures trucks start reliably in environments such as northern logistics routes or high altitude job sites.

For fleet operators, this means fewer emergency calls, reduced towing costs, and less downtime during winter operations.

2. High Power for Heavy Duty Engines

With 3000A peak current output, the unit is capable of starting diesel engines up to 560 horsepower. The 58800mAh energy reserve supports more than 80 jump starts per charge under normal conditions.

This makes it ideal for Class 8 trucks, buses, construction machinery, and agricultural equipment where consistent cranking power is critical.

3. Fast Charging and Long Lifecycle

The DC 29V 5A fast charging system fully recharges the unit in less than 1.5 hours, minimizing downtime between uses.

The built in lithium cells offer over 2000 charge cycles, ensuring long term value for commercial users who rely on daily operation. This reduces replacement frequency and lowers total ownership cost.

Donjelion 373-P1 is widely used in professional transport and industrial sectors including:

• Long haul semi trucks and logistics fleets
• Construction machinery such as excavators and loaders
• Agricultural equipment including tractors and harvesters
• Buses, RVs, and commercial vans
• Marine engines and emergency backup systems

Its dual voltage flexibility makes it suitable for mixed fleet operations where both light and heavy vehicles are used.
