How to Pick the Best Jump Starter
Choosing the best jump starter involves considering several key factors to match your specific needs and vehicle. While numerous options appear similar at first glance, our testing highlights critical distinctions that separate top performers from mediocre models.
Sealed Lead Acid vs. Lithium-Ion Batteries
The battery type is a fundamental consideration. Sealed lead-acid (SLA) and lithium-ion (LI) batteries each offer distinct advantages and disadvantages. SLA batteries are heavier and bulkier but are generally more affordable and reliable, provided they are properly maintained with regular charging. They require recharging after each jump start and tend to self-discharge over time. LI batteries are significantly lighter and more compact, offering greater power-to-weight ratio and longer charge retention. They can also deliver multiple jump starts on a single charge. Visually, LI jump starters are typically slim and modern, while SLA models are larger and resemble traditional battery chargers. Weight is a clear differentiator, with LI units often under five pounds and SLA units exceeding 15 pounds.
How Often Do You Need to Jump-start Your Battery?
Consider your anticipated frequency of jump starter use. Battery capacity varies significantly among models, impacting the number of jump starts and accessory charges available. While manufacturers may list amp-hours (Ah) or milliamp-hours (mAh), watt-hours (Wh) provide a more accurate measure of battery storage potential across different voltages. Models with higher watt-hour ratings offer greater capacity and are preferable if you anticipate frequent jump starts or extended use as a power bank. Our Battery Storage metric directly assesses this capacity.
What Size Battery Do You Need to Boost?
Engine size and battery requirements are crucial factors. Jump starter capability is often indicated by ‘peak amps’, representing the maximum current output. However, real-world performance under load can vary. Our Power Performance metric ranks models based on their ability to deliver sufficient power for different engine sizes. For larger engines, choose models with higher peak amp ratings and robust power delivery, like the HULKMAN Alpha85S or Dewalt DXAEJ14.
Where Will You Store Your Jump Starter?
Storage considerations are important, especially for vehicle owners with limited space. Lithium-ion jump starters are the more compact and lightweight option, ideal for glove compartments or under seats. Sealed lead-acid models are bulkier and heavier, better suited for trunk storage or garage use. Durability is also relevant, particularly if the jump starter will be stored in demanding environments like work trucks. Our Craftsmanship & Durability metric evaluates build quality and resilience to help you choose a model that matches your storage and usage conditions.
