JumpBox | JS3000 Car Jump Starter | 3000A, 24000mAh Multi-Function Booster
Description
24,000mAh Means It Starts the Car More Than Once
Peak amps get the headlines; capacity decides whether you get a second attempt. The JS3000 pairs 3000A of starting output with a 24,000mAh cell, so a stubborn engine that needs three cranks does not leave you with a dead pack and a dead car. Multi-function outputs make it useful the other 364 days of the year.
Why You'll Love It
- 3000A with 24,000mAh capacity – power for the crank and capacity for the retry
- Multi-function outputs – USB charging and a work light, so it earns boot space year-round
- Smart clamp protection – reverse polarity, short circuit and over-current all handled at the clamp
- LCD status display – pack charge and connection state at a glance, not guesswork
- Compact case – fits a glovebox or door pocket, not just the boot
