The Micro-Start XP-10 Heavy-Duty Jump Starter/Personal Power Supply boasts more power and includes the much larger, unbreakable all-copper smart clamps.
Built for mechanics, commercial and daily use, the XP-10 Heavy-Duty puts out an additional 50 Amps of cranking power, versus the original XP-10 model.
The larger wires and jaw of the heavy-duty smart clamps allow a better connection to the battery terminals and have a stronger clamping force that transfers the electrical current better.

SPECIFICATIONS
Clamps have 5 built-in safety protections, including reverse polarity protection, back-charge protection, short-circuit protection and more
