Quick Buying Guide (Key Takeaways)
- Most Powerful: The S8 Ultra Max dominates with 6000A Peak Current and 88.8Wh capacity, capable of starting ANY 12V Gas/Diesel engine (including trucks).
- Best Portability: The S8 Mini is the lightest option at just 0.77 lbs, perfect for glove boxes while still delivering 1200A power.
- Fast Charging Powerhouse: The S8 Ultra Max features 100W PD Input/Output, making it powerful enough to charge laptops and recharge itself incredibly fast.
- Best 2-in-1 Solution: The MF159 combines a 2000A jump starter with a high-speed inflator (22L/min) and can even inflate air beds with its separate 220L/Min high-volume pump.
Frequently Asked Questions
Which jump starter can handle diesel engines?
For smaller diesels (up to 3L), the standard S8 or S8 Mini is sufficient. For larger diesel trucks (up to 10L or All Diesel), we recommend the S8 Ultra+ or S8 Ultra Max, which are specifically designed for heavy-duty applications.
Can I charge my laptop with these?
Yes, but only specific models. The S8 Ultra Max supports 100W Power Delivery (PD), which is sufficient to fast-charge most modern laptops (MacBook Pro, Dell XPS, etc.).
What is the difference between S8 Air and S8?
The S8 Air is a "Hybrid" model that includes a built-in 150 PSI air compressor, allowing you to inflate tires in addition to jump-starting your car. The standard S8 is purely a jump starter and power bank (lighter and smaller).
