Can I take the GOOLOO GP4000 jumper pack on a plane?

Yes, this jump starter is airline-safe. With a battery capacity under 100Wh, it complies with FAA/IATA regulations for carry-on devices.

Can I leave a jump starter plugged in all the time?

No, you can't do that. Many people assume leaving the jump starter connected to the car after a successful engine start will quickly recharge it, but this is a common misconception. Doing so is not advisable and can lead to unintended consequences.

How long should it take to jump a car?

Once the jumper cable is properly connected to the car battery, the GOOLOO GP4000 battery jumper starter will quickly start the vehicle within 3 seconds.

Can I jump out of the car on a rainy day?

Don't worry too much. It's safe to jump-start in rain. Vehicle voltage is low, and light rain won't harm if you follow proper steps. Just keep the Jumper cables and product interfaces dry during the process.

Can this be used to charge a battery out of the car?

Sorry, this portable jump starter can't charge the car battery directly.
