Jumper cables have one fatal flaw: they need a second car. At 6am in an empty parking garage, that's a problem.
Why lithium jump starters won
- Self-contained — 2000A+ from a box smaller than a book
- Safe — spark-proof clamps refuse wrong connections; cables don't
- Multi-use — USB power bank + flashlight built in
- 20–40 starts per charge
Sizing
1000A covers petrol up to ~6L (NOCO GB40). 2000–2500A handles big diesels. Want tire inflation too? The WOLFBOX 3-in-1 adds a 160 PSI compressor.
