JS621N Sodium-ion Jump Starter

The sodium-ion battery inside the JS621N is designed for enhanced safety and stable performance, reducing risks associated with conventional battery systems while delivering up to 2000A peak current for fast, reliable engine starts.

Moving beyond traditional lead-acid chemistry and high-energy lithium systems, sodium-ion technology introduces a new approach to starter batteries — optimized for cold climates, engineered for safety, and built for real-world reliability.

Featuring a 12V DC/10A accessory socket, it powers external devices such as tire inflators, helping you handle roadside emergencies with ease.

Designed for harsh conditions, the built-in LED emergency light ensures visibility during cold-weather breakdowns and low-light roadside situations.
