The sodium-ion emergency jump starter is a portable vehicle jump-starting device powered by next-generation polyanion sodium-ion cells. Compared to traditional lithium-ion jump starters, it offers superior low-temperature performance (delivering a high current of 650A effortlessly at -30°C), enhanced safety (no fire risk at high temperatures of 80°C and no capacity degradation), and a longer lifespan (over 3,000 charge-discharge cycles). Compared to traditional lead-acid jump starters, it is more compact, approximately 60% lighter, and requires less frequent charging, making it ideal for carrying in the vehicle.

This is precisely the core advantage of sodium-ion cells! Traditional lithium batteries suffer a significant drop in discharge performance below 0°C and can even "freeze up" and fail to operate at -20°C. In contrast, sodium-ion cells exhibit excellent low-temperature activity, capable of delivering a 650A 3-second starting current even in extreme cold as low as -30°C.

Yes. Sodium-ion cells feature an extremely low self-discharge rate. When left fully charged inside a vehicle, they retain over 80% of their capacity after 24 months of inactivity, ensuring readiness for critical moments and completely resolving the pain point of batteries losing power and becoming unusable after just a few months of storage. Even if left to discharge to 0V over an extended period, they can be recharged and used again; sodium-ion batteries are resilient against over-discharge.

This product is designed specifically for 12V vehicles and supports all 12V gasoline and diesel vehicles. Other applications: It is also suitable for the emergency starting of equipment with 12V batteries, such as motorcycles, yachts, lawnmowers, and generators.

Yes. The product comes with smart battery clamps and features a built-in "Boost" mode. If the vehicle's battery is completely dead or damaged, pressing the Boost button on the clamps or the jump starter allows for a high-current output to force-start the engine.

Absolutely. This product features integrated fast-charging USB and Type-C ports, as well as a high-brightness LED emergency light (supporting steady-on, flashing, and SOS modes). It allows for the rapid charging of mobile phones, tablets, in-vehicle devices, and more—whether outdoors or in an emergency.

Exceptional safety with thermal stability far surpassing that of lithium-ion batteries. Inherent material safety: Sodium-ion cells feature a very high thermal runaway threshold, making them resistant to fire or explosion even when punctured or exposed to high temperatures; cell capacity remains unaffected after eight hours of storage at 80°C. Nine-layer intelligent safety protection: Paired with an intelligent protection clamp, the system incorporates multiple safeguards—including protection against reverse polarity, short circuits, overcharging, over-discharging, reverse charging, and overheating—and automatically triggers an audible alarm without sparking if the positive and negative terminals are connected incorrectly.

It will not be rendered unusable and supports recovery from zero-voltage (0V) states. While traditional lithium-ion batteries often become permanently unusable ("die") after deep over-discharge, sodium-ion cells possess exceptional resistance to over-discharge; even after being fully depleted for an extended period, they can be reactivated and restored to normal operation simply by reconnecting the charging cable.

Sodium-ion cells offer a cycle life of over 3,000 cycles (compared to the typical 500–1,000 cycles of traditional lithium-based jump starters). With typical household backup usage, the lifespan can reach 5 to 8 years.
