UTRAI 4000A Car Jump Starter – 16000mAh Power Bank with 10W Wireless Charging

A Dead Battery Should Never Leave You Stranded

A flat car battery is one of the most disruptive things that can happen to your day. It happens without warning — often in the worst possible location, at the worst possible time. You left the lights on. The battery is old and finally gave up. The cold weather drained it overnight. Whatever the cause, the result is the same: you are stuck, you need help, and you are dependent on finding another driver willing to stop and jump-start your car, or waiting for a breakdown service that may take hours to arrive.

The UTRAI 4000A Car Jump Starter makes you independent of both. With 4000A of peak current — enough to start petrol engines up to 10 litres and diesel engines up to 8 litres — this compact device jump-starts your car from its own battery, without needing another vehicle. You connect the clamps, press the button, and your car starts. The entire process takes less than two minutes, and you are back on the road without waiting for anyone.

4000A Peak Current — Starts Cars, Vans, and SUVs

The 4000A peak current is the specification that determines which vehicles this jump starter can start. At 4000A, it is capable of starting petrol engines up to 10 litres and diesel engines up to 8 litres — covering the vast majority of cars, vans, SUVs, and light commercial vehicles on UK roads. This is not a device for small hatchbacks only; it is a professional-grade jump starter capable of handling the largest engines in common use.

The intelligent clamp system includes protection against reverse polarity, short circuits, and overcharge — preventing damage to the vehicle’s electrical system and to the jump starter itself during the connection process.

16000mAh Power Bank — Charge Your Devices While You Travel

The 16000mAh battery capacity that powers the jump starter also functions as a high-capacity power bank for charging phones, tablets, and other USB devices. The large capacity means it can charge a smartphone multiple times from a single charge of the jump starter itself — making it a genuinely useful everyday carry device, not just an emergency tool that sits in the boot unused.

10W Wireless Charging — Cable-Free Device Charging

The 10W wireless charging pad allows Qi-compatible devices to charge without a cable — simply place your phone on the pad and it charges. The 10W output delivers fast wireless charging for compatible devices, making the UTRAI a versatile charging solution for the car as well as an emergency jump starter.

Propulsion Booster Technology — Reliable Starting in Cold Conditions

The propulsion booster technology ensures reliable starting performance in cold weather conditions — the conditions where flat batteries are most common and where conventional jump starters can struggle to deliver sufficient current. The booster function provides the additional current surge needed to start cold engines reliably.
