Car Emergency Starter Power Bank – 20000mAh Polymer Lithium Jump Starter with SOS Light and USB Output

When your car battery dies unexpectedly, a reliable jump starter is more than a convenience – it is a practical safety tool. This car emergency starter power bank packs 20000mAh of polymer lithium battery capacity and delivers 300A starting current (600A peak) to restart most petrol and diesel vehicles. Its built-in SOS light provides visibility in breakdown situations, and the multi-U port USB output at 5V/2.1A means you can also charge phones, tablets, or other devices. Designed around a robust ABS shell and measuring 160 x 80 x 32mm, this unit is compact enough to keep in the boot without taking up excessive space. The package includes the starter itself, a colour-coded battery clip (red positive, black negative), a wall charger, a car charger, and a retail toolbox for organised storage.

Features and Construction

This jump starter combines a powerful polymer lithium battery with practical build features that make it suitable for both emergency roadside use and everyday charging. The key specifications are grounded in the source data.

Battery and Power Specifications

The unit uses a polymer lithium-ion battery with a stated capacity of 20000mAh. Starting current is rated at 300A, with a peak current of 600A for short bursts during the jump-starting process. Charging input can accept 15V at 1A or 5V at 2A, and USB output delivers 5V/2.1A via multiple ports. This combination allows the power bank to restart engines and recharge personal electronics.

Construction and Materials

The shell is made from ABS, a lightweight and impact-resistant plastic that protects the internal battery and circuitry. The unit is finished in red and measures 160mm in length, 80mm in width, and 32mm in depth, making it portable enough to store in a glovebox or boot compartment.

Safety and Emergency Features

An integrated SOS light provides a flashing or steady light source for signalling in low-visibility or emergency situations. The included battery clip uses colour-coded leads (red for positive, black for negative) to help correct connection during use.

Uses and Placement

This device is designed for vehicle owners who want a portable, self-contained jump-starting solution that also doubles as a power bank. Its use cases span emergency roadside scenarios and everyday charging needs.

Vehicle Jump-Starting

With 300A starting current and 600A peak current, the unit is suited to starting most petrol and diesel engines that fall within its power range. The colour-coded battery clip simplifies connection to the vehicle battery terminals.

Device Charging On the Go

The multi-U port USB output at 5V/2.1A allows simultaneous charging of smartphones, tablets, and other USB-powered devices. This makes the unit useful for charging gadgets during journeys, camping trips, or power outages without needing a separate power bank.

Emergency Signalling

The SOS light adds a safety layer for breakdowns at night or in low-visibility conditions. It can be used to alert other motorists or signal for assistance, increasing roadside safety when the vehicle is immobile.

Benefits and Buying Value

This product merges two common needs – jump-starting a car and charging personal electronics – into one compact unit, reducing the number of separate devices you need to carry in the vehicle.

All-in-One Practicality

Instead of carrying a separate jump starter, power bank, and emergency light, this single device covers all three functions. The 20000mAh capacity provides enough charge for multiple jump starts or extended device charging before the internal battery needs recharging.

Compact Storage

Measuring just 160 x 80 x 32mm and housed in an ABS shell, the unit is small enough to stow in a door pocket, under a seat, or in a boot toolbox. The included retail toolbox keeps all components together and organised.

Low Maintenance Readiness

The polymer lithium battery retains charge well when stored, requiring only periodic recharging – using the supplied wall charger or car charger – to remain ready for use. No specialist care or regular replacement of internal cells is needed beyond normal battery maintenance.
