15 Best Instant Car Battery Chargers
for March 2023

When a car battery dies, you're stuck. Electrical systems in your vehicle rely on the battery to start your engine and keep you running. So, it's crucial to have backup or "jump starters" on hand to keep a car running.

While you can easily jump-start a car with a portable, hand-operated jump starter, that's not the best option if you have a car battery that's dead and won't start. Instead, we recommend investing in an automotive car battery charger that can charge a dead battery in minutes.

Our experts in the MOOZ Reviews Lab test car battery chargers for performance and ease of use. We look at charging time, voltage output, temperature, and weight. Our top pick is the Powerwerx PW3-1. This powerful 12-volt charger can charge a dead battery in 45 minutes and holds a charge for up to 25 hours. The compact size makes it easy to store in the car, and it charges both car and motorcycle batteries.

With car battery chargers, it's all about performance. We test each model by charging a dead battery, and time how long it takes to complete the process. We then test the charger's voltage output, temperature, and weight. We also look at the charger's built-in safety features
