Buying Guide: Key Purchase Considerations
- Engine compatibility: Match peak power with your vehicle’s engine size. For most cars, 1000–4000A is sufficient; diesel engines and larger engines require higher power models.
- Portability vs. power: Ultra-compact models prioritize weight and pocketability but may offer lower peak currents. Balance your portability needs with the worst-case start power you expect.
- Safety protections: Look for features such as spark-proof, reverse polarity, short-circuit protection, overheat protection, and overload protection. More protections reduce risk during misconnection.
- Battery type and charging: Lithium-based packs are lighter and have better efficiency. Check charging time and USB output options if you plan to use the unit as a power bank.
- Additional features: Built-in flashlights, inflators, LCD displays, and multiple USB ports add value for emergencies and daily use. Consider what extras you will actually use.
