Here’s a detailed guide on what to look for.

#### 1. Peak Amperage (Cranking Power)

This is perhaps the most critical specification. Peak amperage indicates the maximum current the jump starter can deliver. It’s the raw power needed to crank a stubborn engine.

A higher peak amperage means more starting power. This is especially important for larger engines or in cold weather. Cold temperatures make batteries less efficient.

Look at your vehicle type. A compact car needs less power than a large SUV or a diesel truck. Overpowering is generally not an issue, but underpowering definitely is.

* For Small Cars (4-cylinder gasoline): Look for 400-600 peak amps.
* For Mid-Size Sedans/SUVs (6-cylinder gasoline): Aim for 600-1000 peak amps.
* For Large Trucks/SUVs (8-cylinder gasoline): Consider 1000-1500 peak amps.
* For Diesel Engines (any size): Diesel engines require significantly more power. Look for 1500-2500+ peak amps.

Some manufacturers also list “Cranking Amps” (CA) or “Cold Cranking Amps” (CCA). These are more consistent measures but are less commonly found on portable units. Peak amps are the standard for these devices.

Ensure the peak amperage rating is sufficient for your specific vehicle. Check your car’s battery specifications if unsure. More power offers more versatility and reliability.

#### 2. Battery Capacity (mAh or Wh)

Battery capacity tells you how much energy the jump starter stores. It indicates how many times you can jump-start a car on a single charge. It also affects how long it can power other devices.

Capacity is usually measured in milliamp-hours (mAh) or watt-hours (Wh). A higher number means more reserve power. This is useful if you need multiple jumps or plan to charge electronics.

For most occasional users, a moderate capacity is fine. If you have an older car or frequently travel, a higher capacity unit provides extra assurance.

Consider how often you might use it. If it’s just for emergencies, a unit with enough power for 1-3 jumps is usually sufficient. For extended use or multiple vehicles, go bigger.
