27500mAh 2000A UltraSafe Jump Starter – 12V Sodium Battery Booster Pack, Portable Jump Box, PD60W Power Bank & Jumper Cables

GOKKCL jump starter redefines portable power with its advanced sodium-ion battery technology.

Enjoy ultra-fast charging, long-lasting reliability, and an incredibly low self-discharge rate, ensuring your vehicle is always ready to go. Built to perform in extreme conditions, the GK03 provides peace of mind and superior performance, making it the ultimate power solution for any car travel.

Why choose sodium battery？

Thanks to the superior performance of sodium-ion batteries, the GK03 can be fully discharged to 0 volts and remain at 0 volts for an extended period. Even after 48 months of standby, the self-discharge rate is less than 50%, with minimal fire risk.

This significantly reduces the safety concerns associated with traditional batteries, providing you with peace of mind.

Wide Temperature Tolerance

Unlike lithium-ion batteries that typically function only within a narrow temperature range, the sodium-ion battery in this jump starter operates efficiently in extreme temperatures, from -40°C to 80°C. This wide range ensures it remains effective in both scorching summers and freezing winters, making it a reliable tool in all climates.

Zero Voltage Discharge Capability

The sodium-ion jump starter has the unique ability to discharge down to 0 volts without causing damage to the battery. This feature is particularly valuable in scenarios where the battery has been completely drained, allowing it to be revived and used again, unlike lithium-ion batteries that may become irreversibly damaged if discharged too far.

100C High Discharge Rate

Capable of delivering up to 100 times its rated capacity instantly, ensuring your vehicle starts up smoothly even in the most demanding situations, such as extreme cold or high power requirements

Peak Current of 1350A

With a peak current of 1350A, the jump starter delivers powerful cranking force, ensuring quick and effective starts for both 6.0L gasoline and 3.0L diesel engines.

Versatile and Multi-Functional

This powerful backup power bank offers multiple discharge modes, making the most of your stored energy. Equipped with USB 5V/2.4A and USB-C PD60W output ports, it charges various devices, ensuring you're never out of power when outdoors.

Massive 27500mAh Capacity

With a high-capacity battery, this power bank ensures extended use for emergency starts and devices, providing enough power to charge phones, laptops, and even small appliances like mini fridges.

Portable Power Anytime, Anywhere（80Wh）

At just 80Wh, this device is FAA-compliant, meaning you can take it onboard flights without worry, offering ultimate convenience for travel or road trips. Whether you're stuck in the middle of a highway or stranded at a remote location, this jump starter ensures you’re never without power when you need it most.

FAQs

Q1: What makes the GK03 different from traditional jump starters?
GK03 uses advanced sodium-ion battery technology. Compared with traditional lithium batteries or lead-acid batteries, it has stronger safety performance, faster charging speed, longer service life, lower self-discharge rate, and superior performance in low temperature environments, making it suitable for extreme climate conditions.

Q2: What problems can this all-weather sodium battery starting power supply solve?
It can provide starting protection for the car in extreme weather (such as severe cold, scorching heat or heavy rain). Especially in low-temperature areas in winter, many lithium battery starting power supplies cannot work properly, but our product can stably start the car in an environment of -40°C, saying goodbye to the trouble of "not starting".

Q3: Is this sodium battery starting power supply safe? Will there be an explosion risk like lithium batteries?
Sodium batteries are safer than lithium batteries. They have a higher thermal runaway temperature and almost no explosion risk. In addition, our products have passed multiple safety tests, including overcharge, short circuit protection and anti-reverse connection protection, which makes it safer to use.

Q4: My car is a diesel car, or has a large displacement. Is this product suitable for me?
Of course it is! It supports starting gasoline cars with a displacement of up to 6.0L and diesel cars with a displacement of 3.0L, whether it is an ordinary car, SUV or light truck.

Q5: Are sodium-ion batteries heavier and easier to carry?
The energy density of sodium-ion batteries is slightly lower, but we have optimized the product design to ensure that it is lightweight and high-performance. The whole machine weighs only 1.7kg and comes with a portable storage bag, which is convenient for car owners to carry at any time.

Q6: I don’t use the starting power supply often. Will it run out of power quickly when placed in the car?Can it be used as a mobile power supply?
Yes, it supports USB interface output, can charge mobile phones, tablets and other devices, and can be used as a mobile power supply in emergency situations. In addition, its battery cycle life is longer, and it can standby for up to 5 years after a full charge.

Q7: Are sodium battery starting power supplies more expensive than lithium batteries? Are they really worth buying?
The price may be slightly higher, but the performance and safety are far superior to lithium batteries. Sodium batteries are more stable in low temperature environments, less prone to overheating or explosion, and more suitable for all-weather use. It is a one-time investment that provides years of peace of mind.
