NHOWIN 4000A Jump Starter Power Pack 12V

This compact jump starter delivers rapid assistance when a vehicle battery fails, offering a high peak current and a portable power bank to keep devices charged on the move. Designed for roadside emergencies and outdoor trips, it starts petrol engines up to 7.5 litres or diesel engines up to 5.0 litres and includes a torch and compass for added utility, which makes it useful during winter or travel. ⚡

Key Points

The unit provides a peak current capable of starting most cars, SUVs, vans and motorcycles quickly, according to the manufacturer. It incorporates smart jumper cables with ten layers of protection such as over-current, over-charge, reverse-connection and short-circuit safeguards, and an audible alarm with automatic circuit cut-off if clamps are connected incorrectly. The device also acts as a portable power bank with a quick-charge USB output rated at 9V/2A, so you can top up phones and tablets while on the road. 🔋

This model is lightweight at about 0.84 kg, which makes it easy to stow in a glovebox or carry pouch. The integrated torch features three modes: steady light, strobe and SOS, offering visibility in low-light situations. The manufacturer states that the internal management system maintains over 95% of charge after long standby periods, reflecting the product’s intelligent charge preservation.
