How many times can I jump-start a vehicle on a single charge?

It depends on battery size and how drained it is, but the 15000 mAh capacity supports multiple full jump cycles. After heavy use, recharge via the included USB cable—full recharge takes a few hours depending on your charger.

Will this work with my truck or larger engine?

1500A peak output covers most standard sedans and light trucks. If you're running a diesel or large displacement engine, verify your cold cranking amp requirement against the unit's specs before relying on it as your primary jumper.

What if I reverse the clamp connections by mistake?

Built-in reverse polarity protection prevents damage to your vehicle's battery and electrical system. The unit will simply not activate—reconnect the clamps in the correct order (red to positive, black to negative) and try again.
