What to know before buying

Listing details to confirm

The listing gives a 3000A peak figure alongside a 750A-for-two-seconds output claim. Treat both as listing specifications rather than equivalent continuous output. Its engine-size, jump-count, charging-time and runtime figures are also unverified claims. Confirm your vehicle's requirements and follow the supplied instructions. The listing calls the DC port 16.8V, while describing it as suitable for 12V DC devices, so check accessory compatibility before use.
