Key item features

  • 4000A POWER FOR ROADSIDE STARTS - Be ready when a weak battery interrupts your day. The 4000A jump starter is designed for 12V vehicles with engines up to 10.0L gas or 8.0L diesel, giving you dependable backup power for cars, SUVs, pickups and other everyday vehicles.

  • CHECK STATUS AT A GLANCE - The clear digital display makes remaining battery level and operating status easy to check before a jump start. A quick glance helps you know when the unit is ready to use and when it is time to recharge.

About this item

Product details

A dead battery can turn a normal drive into an unexpected stop. The NEXPOW 4000A jump starter gives you a practical way to get moving again without waiting for another vehicle. Designed for 12V vehicles with engines up to 10.0L gas or 8.0L diesel, it is a useful backup for daily driving, family vehicles and long road trips. The clear digital display, smart jumper cables and Force Start function are designed to make stressful low-battery situations easier to handle. Keep it charged in your vehicle so you can respond at home, in a parking lot or on the roadside without relying on another vehicle for a jump. Once the engine is running, the same compact power source stays useful on the road. The built-in 16800mAh battery provides backup power for everyday USB devices, while the built-in LED light helps provide visibility around the vehicle after dark. One portable tool gives you starting power, backup charging and roadside lighting for the situations drivers are most likely to face away from home.

Great Charger! Well worth the price!

This charger is amazing! Starts my SUV on the first try, every time. Once, the charger was very low, under 10% charge, and it still worked beautifully! It recharges quickly, keeps a charge for a long time, is compact and efficient. Well worth the price, for the peice of mind alone.
