When you need a jump, you’ll connect the clamps to the battery, ensuring polarity is correct, then engage the jump function. The product is spark-proof and includes reverse polarity protection, so even if you make a connection mistake, the device is designed to stop damage before it happens.

You’ll like the Force Start feature if your battery is completely drained; it helps bring the battery to a level where the vehicle can crank.

Diagnostic capabilities (OBD2 scanner)

You can plug this device directly into your vehicle’s OBD2 port to instantly read and interpret check engine codes. The onboard library contains 83,100 codes and is designed to do more than display a number—you’ll see what the code means and often why it’s triggered so you can make informed decisions about repairs.

You’ll be able to read and clear codes, view freeze frame data, monitor live parameters, perform an I/M readiness check, run an O2 sensor test, and even retrieve the vehicle VIN. This can save you time and money by helping you determine whether a mechanic visit is necessary.

Live data and battery health monitoring

Real-time voltage curves let you watch what your battery is doing while the engine runs and during cranking. That means you can detect early signs of battery aging or charging system problems rather than guessing based on weak starts or erratic electronics behavior.

You’ll find this especially useful if you want to track trends over time—capturing live voltage data can help you identify intermittent charging issues that might otherwise be missed.

Power bank and emergency light

With a 16,800 mAh internal battery and up to 24 months standby, this unit doubles as a reliable power bank for your phone and other USB devices. That’s convenient during emergencies or outdoor trips when you need to keep devices charged.

You’ll also get a bright wide-angle light with three modes: flashlight, strobe, and SOS. That light helps with roadside repairs, signaling for help, and general illumination during night work.

Safety features and protections

Safety is a big selling point here. The device touts 10 essential protections, including reverse polarity protection, spark-proof circuitry, and short-circuit protection. The jumper cables and clamps are designed to prevent damage from accidental misuse and protect both you and your vehicle’s electronics.

You’ll also benefit from the V0 rated flame retardant materials and reinforced casing, which reduce risk in the event of mishandling or extreme conditions.

Connector and cable design

The extended cables make it easier to reach a battery even in tight engine bays, and the secure clamps reduce the chance of slips during attachment. The device’s protective circuits should prevent most common hazards, but you should still follow the standard safe jump-start sequence and instructions.

How to use the product: jump starting step-by-step

These steps will help you jump-start a vehicle safely and efficiently using this unit.

1. Make sure the jump starter is charged. A partially charged unit may not be able to deliver the necessary peak current.
2. Turn off the vehicle and remove any metal jewelry to avoid shorting.
3. Connect the red clamp to the positive (+) terminal on the dead battery.
4. Connect the black clamp to a clean, unpainted metal part of the engine block or vehicle chassis (ground), not the negative terminal on some vehicles where a ground point is preferred.
5. Confirm the device shows a correct connection. The device is spark-proof and should indicate readiness.
6. Start the vehicle. If it doesn’t start within a few seconds, wait a minute and try again. Avoid continuous cranking—use short starts.
7. Once the vehicle is running, remove the clamps in the reverse order: black ground first, then red positive.
8. Recharge the jump starter soon after use so it remains ready for the next time.

You’ll get the best results if you follow these basic safety and usage steps rather than attempting improvised sequences.

How to use the product: OBD2 scanning step-by-step

Using the OBD2 functions is straightforward, and the product’s interface helps you interpret results.

1. Locate the OBD2 port in your vehicle (usually under the dashboard near the steering column).
2. Plug the OBD2 cable from the device into the vehicle port.
3. Turn the ignition to the “ON” position without starting the engine (or follow the device’s instructions).
4. Use the device’s menu to select “Read Codes” or “Live Data” as needed.
5. Read the code(s) and follow the on-screen description to understand the issue.
6. If appropriate, clear codes after verifying the issue is resolved by choosing “Clear Codes.”
