Features and Construction

The K4-E combines emergency vehicle starting capability with portable power bank functionality in one compact unit. Its construction centres around a polymer battery system specifically designed to deliver the surge current needed for jump starting while maintaining efficiency for device charging applications.

Material and Build

At the core of the K4-E is its power polymer battery cell configuration arranged in three strings. This construction provides the necessary power density for the unit's dual functions. The polymer battery technology offers a balance between capacity and physical dimensions, enabling the 6000mAh rating within the compact 139 x 79 x 25mm housing. The complete set including all components weighs 460g, making it easily portable for emergency situations or daily use as a power source.

Size and Practical Fit

With dimensions of 139mm length, 79mm width, and 25mm thickness, the K4-E maintains a slim profile that fits conveniently in most vehicle storage compartments. The 460g full set weight ensures it's lightweight enough for regular carrying without adding significant bulk. The unit comes packaged individually in a 17 x 11 x 9cm box, with master shipping cartons measuring 54 x 35 x 40cm for retail distribution. These compact dimensions make the K4-E suitable for keeping in your vehicle year-round without sacrificing valuable storage space.

Uses and Placement

The K4-E serves multiple purposes depending on your immediate needs, from emergency vehicle assistance to everyday electronic device charging. Its compatibility ranges from vehicle starting applications to powering personal electronics through standard USB charging.

Event or Professional Use

For professional drivers or those frequently travelling in remote areas, the K4-E provides essential backup power for vehicle starting emergencies. The unit is specifically designed for petrol vehicles with engines up to 2.0 litres displacement, making it suitable for most standard passenger cars, smaller SUVs, and light commercial vehicles. The touch-activated power display allows quick checking of remaining capacity before attempting a jump start, providing confidence that sufficient power is available. This feature is particularly valuable for roadside assistance professionals or fleet operators managing multiple vehicles.

Everyday Home Use

Beyond emergency starting applications, the K4-E functions as a versatile power bank for household electronics. Its 5V/2A output supports charging mobile phones, tablets, GPS navigation devices, portable media players, and other compatible USB-powered electronics. The 6000mAh capacity provides substantial charging capability for multiple devices between vehicle uses. Keeping the unit charged via its 5V/2A input ensures it's ready for both emergency vehicle starting and everyday charging needs, making it a practical addition to any household's electronic accessories.

Benefits and Buying Value

The K4-E emergency power supply offers practical advantages through its dual functionality and straightforward operation. Its design prioritizes ease of use with clear power monitoring and broad compatibility with common electronic devices.

Reuse and Low Maintenance

Unlike single-use emergency starting products, the K4-E is designed for repeated use with proper recharging between applications. The polymer battery technology supports regular charging cycles through the 5V/2A input, maintaining readiness for future needs. The touch power display provides immediate feedback on remaining capacity, helping users maintain the unit at optimal charge levels. This reuse capability makes the K4-E a cost-effective solution compared to disposable alternatives, particularly for drivers who experience occasional battery issues or frequently use portable electronics in their vehicles.
