The battery capacity of the A68 is 32000mah=118.4Wh.

We recommend that you use a 9V/2A or 12V/1.5A wall charger. In general, it takes 6-7 hours to fully charge the jump starter using a 9V/2A or 12V/1.5A wall charger.

The A68 jump starter has a force start function and is located on the side of the jump clamp.

Every car battery is different, so there are two scenarios:

1. When the jump clamps are connected to any car battery, they will automatically turn to a green light, so you don't need to press the jump-start button. Instead, you can start your car directly.

2. When the jump clamps are connected to any car battery and the light does not turn green, you must press and hold the jump-start button for 3 seconds until the indicator light turns green, then you can start your car immediately.

Note: The A68 jump clamps have a start timeout mode, meaning the green light will only stay on for 35-45 seconds. If you have not started your car within that time, the green light will turn blue again. You will need to disconnect the jump clamps from the car battery and reconnect them.

One light indicates 25% power, so four lights indicate 100% power. When the first light is flashing, it means the jump starter is charging. When the first light is on and the second light is flashing, the jump starter has 25% power. When all four lights are solidly on, it means the jump starter is fully charged.

Note: When the jump starter is fully charged, the blue light won't stay on all the time, it will go out after 10 seconds. You can press the power button to check the light.

We recommend that you fully charge the jump starter before using it. Using it when the battery is low will cause serious damage to the jump starter.

In the U.S., you can generally bring a jump starter on a plane if the battery capacity is within certain limits. Specifically, you can carry jump starters with lithium-ion batteries that do not exceed 100 watt-hours (Wh). If the battery capacity is between 100 Wh and 160 Wh, you need to get approval from the airline before bringing it on board​.

According to the Federal Aviation Administration (FAA) and the Transportation Security Administration (TSA), lithium-ion batteries must be carried in your carry-on luggage and are not permitted in checked baggage. It's advisable to keep the battery protected to prevent short circuits, and storing it in its original packaging or wrapping it in insulating material can help ensure safety.

For the most up-to-date information, it's a good idea to check with your airline or refer to the TSA's website before travelling. You can find more details about these regulations.
