Car Emergency Starter Power Bank 20000mAh with 300A Starting Current and SOS Light

This car emergency starter power bank is a practical solution for drivers who want a reliable backup when the battery dies. With a 20000mAh polymer lithium-ion battery, it delivers a starting current of 300A and a peak of 600A, enough to restart most petrol and diesel engines. The built-in SOS light adds an extra layer of safety during roadside emergencies, while the multi-U port output lets you charge smartphones, tablets, and other USB devices without needing a separate power bank. The unit is housed in a tough ABS shell and measures a compact 160*80*32mm, making it easy to store in a glovebox or boot.

Features and Construction

Designed for both emergency jump-starts and everyday device charging, this power bank combines a high-capacity battery with practical connectivity options.

Material and Build

The outer casing is made from ABS (Acrylonitrile Butadiene Styrene), a material known for its impact resistance and ability to withstand moderate heat. Inside, the polymer lithium-ion battery provides a stable 20000mAh capacity with minimal self-discharge. The unit comes in red and includes clearly marked battery clips (red for positive, black for negative).

Size and Practical Fit

Measuring 160*80*32mm, the power bank is slim enough to slide into a glovebox or under a car seat. Its lightweight build allows for easy handling during roadside use, and the textured ABS surface provides a secure grip.

Uses and Placement

Whether you are on a long journey or just commuting, this starter power bank offers peace of mind without taking up much space.

Event or Professional Use

For fleet drivers, recovery services, or event logistics staff who need to restart vehicles quickly, the 300A starting current and peak 600A output can handle repeated jump-starts. The SOS light also serves as a warning beacon at night or in low-visibility conditions.

Everyday Home Use

In a domestic setting, the power bank doubles as a portable USB charger for phones, tablets, or other devices during power cuts or outdoor activities. Its multi-U port output allows simultaneous charging of up to two devices at 5V/2.1A.

Benefits and Buying Value

This product replaces the need for separate jump leads and a standalone power bank, offering two functions in one compact device.

Reuse and Low Maintenance

The polymer lithium battery holds its charge well when stored, requiring only periodic top-ups via the included wall or car charger. There are no disposable parts, so the unit can be reused many times without replacement.

Why Choose This Product

With its combination of high peak current, USB charging, and a built-in SOS light, this starter power bank provides a comprehensive emergency kit in a single unit. The 20000mAh capacity ensures enough power for multiple jumps or extended device charging before a recharge is needed.
