Sodium-ion jump starter
The EV511 is the industry's first waterproof sodium-ion 12V car jump starter. It boasts a peak current of 2200A, a capacity of 30000mAh, supports PD60W bidirectional fast charging, and can start 8L gasoline/4L diesel vehicles. It's compatible with motorcycles, SUVs, trucks, and ships, and can also power car refrigerators, lights, and other devices via its 12V DC interface.
The product uses sodium-ion batteries, coupled with a BMS intelligent management system and 10 layers of safety protection. Puncture tests show no risk of fire or explosion. The battery has a cycle life of 4000 cycles, and the entire unit can be used for over 10 years, requiring no regular recharging maintenance. Its operating temperature range is -40℃ to 80℃, making it suitable for extreme climates. Its performance is significantly superior to conventional lithium-ion jump starters.
The device features an LED digital display screen to monitor vehicle battery voltage; integrated LED lights for lighting, camping, and SOS warning; and a handle for easy storage and carrying. It is suitable for roadside assistance, outdoor camping, night fishing, disaster emergencies, and other scenarios.
