Use a portable jump starter only if both your vehicle’s owner manual and the starter’s instructions permit it. Follow the vehicle manual’s approved terminals, voltage, clamp order and removal procedure; these can vary, especially on hybrids and electric vehicles. If the manual prohibits jump-starting, the battery is frozen or visibly damaged, or you are unsure, stop and call roadside assistance or a service professional.
Before connecting a portable jump starter
“Jump starting can be dangerous if done incorrectly,” Hyundai says in its 2025 U.S. owner manual. Read the instructions for both the car and the starter before touching the clamps. The vehicle manual controls where to connect, what low-voltage system is fitted and whether a jump is allowed at all. Some manufacturers advise against jump-starting; Hyundai recommends contacting a technician or towing service if you are uncertain.
- Park securely, select Park or Neutral as appropriate, set the parking brake, switch off the ignition and turn off electrical accessories.
- Check the battery before proceeding. Do not jump-start a frozen battery or one that is cracked, bulging, leaking or otherwise visibly unsafe.
- Keep flames and other ignition sources away, avoid creating sparks, and wear eye protection. Safety glasses do not make an otherwise prohibited or unsafe jump acceptable.
- Confirm that the vehicle and starter manuals approve the starter’s voltage and the connection points. Do not assume every car uses the same procedure.
How to connect and use the starter
The following is a general outline, not a universal clamp sequence. Use it only when both manuals allow it, and follow their exact instructions if they differ.
- Identify the approved connection points. Locate the vehicle’s designated positive terminal and ground point, which may not be the battery posts. Check the starter manual for its positive and negative clamps and any required device settings.
- Attach the clamps in the specified order. A common arrangement is positive clamp to the discharged battery’s positive terminal, the other positive connection to the starter’s positive output, negative clamp to the starter’s negative output, then the vehicle’s designated ground point. Do not treat this common order as permission to override either manual.
- Start the car as directed. Use the vehicle and starter instructions for activation and starting. Do not improvise a waiting period, cranking duration or number of attempts.
- Remove the clamps in the prescribed order. Keep clamps from touching each other or other metal parts while disconnecting, and follow the manuals’ instructions for shutting down the starter.
Kia example: one manufacturer’s sequence
Kia’s 2026 U.S. owner manual specifies a 12-volt booster source and a sequence of positive to positive, negative to the booster’s negative terminal, and the final negative connection to the vehicle’s designated ground. This is an example for the vehicles covered by that manual, not a universal instruction for other makes or models.

Hybrids and electric vehicles need special care
A hybrid or EV may have a low-voltage system and designated jump points, but its procedure is vehicle-specific. Tesla’s Model 3 owner manual for 2017–2023 vehicles describes different procedures depending on low-voltage battery chemistry and says the Model 3 cannot be used to jump-start another vehicle. Do not assume that a high-voltage traction battery is the battery being jump-started; consult the manual for the exact vehicle and model year.
If the engine still will not start
Stop if the permitted procedure fails. Do not keep trying beyond the limits in the manuals. A no-start can have causes other than a discharged battery; a battery and charging-system diagnosis can help determine whether repair or a replacement car battery is appropriate. Contact roadside assistance or a repair professional rather than assuming a jump has fixed the underlying problem.

Choosing and keeping a portable jump starter ready
Choose a 12-volt portable car jump starter with clamp leads only if that voltage and device type are approved for your vehicle. Check the vehicle application stated by the starter’s manufacturer, its clamp-safety protections and instructions, its charge-status guidance, and its storage limits. AAA describes a portable starter as a battery pack with jumper cables that can be used without another vehicle. No single peak-current threshold or starter model is established here as right for every car.
