How We Tested the Best Jump Starters for Car
Our testing process for identifying the best jump starter for car was rigorous and comprehensive. We included models ranging from 1000 to 2000 peak amps, representing a broad spectrum of capabilities. Each jump starter underwent a series of tests designed to push its performance limits. We tested them on vehicles ranging from a small motorcycle to a large V8 diesel truck and even a powerful boat engine.
We meticulously monitored voltage and current during jump starts and assessed how many consecutive cold starts each unit could provide, even bypassing the vehicle battery entirely in some tests. Our evaluation included both lithium-ion and sealed lead-acid battery types, ensuring a comprehensive comparison across different technologies.
Our testing criteria were divided into five key metrics:
- Power Performance (30% weighting): Evaluating the amperage and voltage output during jump starts, crucial for starting different engine sizes.
- Battery Storage (30% weighting): Assessing battery capacity, longevity, and the number of jump starts and device charges provided.
- Craftsmanship & Durability (20% weighting): Examining build quality, water resistance, cable robustness, and overall durability for long-term use.
- Ease of Use (15% weighting): Evaluating the intuitiveness of operation, display clarity, and convenience of features like built-in flashlights.
- Versatility (15% weighting): Assessing additional features such as USB charging ports, air compressors, and 12V outlets, enhancing overall utility.
Many models also feature integrated flashlights, a practical addition for roadside emergencies.

How to Pick the Best Jump Starter for Your Car
Choosing the best jump starter for car depends on your individual needs and vehicle. While many options appear similar, our testing has highlighted critical differences that can significantly impact performance. Before making a purchase, consider these key factors:
Sealed Lead Acid vs. Lithium-Ion Batteries
The most fundamental difference lies in battery type. Sealed lead-acid (SLA) jump starters are heavier and bulkier but are generally more affordable. Lithium-ion (LI) jump starters are significantly lighter and more compact, offering more power per pound and better energy density. LI batteries also tend to hold a charge longer and can provide multiple jump starts without needing immediate recharging, whereas SLA batteries typically require recharging after each use. Visually, LI jump starters are slim and modern, while SLA models are larger and boxier. Weight is a key differentiator, with LI packs usually under 5 pounds and SLA packs often exceeding 15 pounds.
How Often Will You Use Your Jump Starter?
Consider how frequently you anticipate needing a jump starter. If it’s primarily for occasional emergencies, battery storage capacity becomes crucial. While manufacturers may list milliamp-hours (mAh) or amp-hours (Ah), watt-hours (Wh) provide a more accurate measure of battery storage potential across different voltages. Models with higher watt-hour ratings offer more jump starts per charge. Our Battery Storage metric in the comparison chart helps evaluate this aspect.
What Size Engine Do You Need to Jump?
Engine size is a critical factor in jump starter selection. Peak amps, the maximum current output, indicates a jump starter’s capability. Higher peak amp ratings generally mean better performance for larger engines. However, real-world performance can vary under load. Our Power Performance metric ranks models based on their actual output capability, guiding you towards the best jump starter for car based on your engine size.
Where Will You Store Your Jump Starter?
Storage space and portability are important considerations. Lithium-ion jump starters are the clear choice for those needing a compact and lightweight option. However, durability is also a factor, especially if the jump starter will be stored in a work truck or harsh environment. Our Craftsmanship & Durability metric helps identify models built to withstand rough use, including water resistance and robust construction.
