In short
- For a Fiat 500 you need a jump starter suitable up to about 420 to 640 CCA, depending on the engine.
- Your battery has a CCA rating (the cold cranking current, listed as EN on the battery label). A jump starter itself has no CCA: the number shows up to which battery CCA it is suitable. Choose a model that covers at least the value of your battery.
- The Fiat 500 is a light city car, so for almost every version the Boost Basic 3000 or Boost Mini 3750 is enough. The 0.9 TwinAir and the 1.3 MultiJet diesel are at the top end; that's where the Boost Pro 8250 comes in.
- Below you'll find the right jump starter per engine variant for the Fiat 500 (2007 to now).
What is CCA and why does it determine your choice?
CCA (Cold Cranking Amps) is the starting power your battery delivers in the cold. The heavier the engine and the colder it is, the more you need. The value is listed as EN on your battery. A jump starter itself has no CCA: the number shows up to which battery CCA it is suitable, so choose a model that matches the EN value of your 500. Want the full explanation, the standards (EN, SAE, DIN) and rules of thumb per engine type? Read what CCA actually is and why it determines your choice. Below you'll see which jump starter is suitable per Fiat 500 engine variant.
