How To Jump Start.
Carefully read and understand the vehicle owner’s manual on specific precautions and recommended methods for jump starting the vehicle. The AX65 is for jump starting 12-volt lead-acid batteries only.

ATTACH CLAMPS.
Connect the battery clamps to the AX65 by connecting to the 12V OUT port. Then, connect the positive (red) battery clamp to the positive (POS,P,+) battery terminal and the negative (black) battery clamp to the negative (NEG,N,-) battery terminal or vehicle chassis.

POWER ON.
Turn off vehicle’s power loads (headlights, radio, AC, etc.) before jump starting. Press the Power Button on AX65 to begin, and all LEDs will flash once. If properly connected to the battery, the white Boost LED will illuminate and battery charge LEDs will chase. 60-Second Timeout countdown will begin when battery is detected.

START VEHICLE.
Start vehicle. If vehicle does not start right away, wait 20-30 sec. and try again. After the 60-sec. timeout, the Product must be powered "OFF", then "ON", to initiate a new jump-start sequence. Do not attempt more than 5 consecutive jump starts within 15 min. period. Allow the AX65 to rest before attempting to jump start again.

POWER OFF.
Once you have started your vehicle, power "OFF" the Product, disconnect the battery clamps, and remove the AX65.

The NOCO Boost Air can be used to jump-start the 12V lead acid starting battery in the vehicle and to inflate its tires. However, the AX65 must not be connected to any other type of batteries, including the high-voltage battery in hybrid vehicles.
Yes, Boost Air is USB-C rechargeable, independent of your country’s electrical standards (e.g., 120V or 220V). It can be charged using any good-quality AC to USB-C adapter, 12V to USB-C adapter, or USB-C-compatible power outlet, including those in vehicles.
Yes. Boost Air can jump start any vehicle with a 12V lead acid battery like a car, boat, motorcycle, ATV, lawn mower, RV, tractor, truck and more.
No, the Boost Air does not have an XGC output to be able to do so.
No. Boost Air is only designed for 12V vehicles. Jump starting a 6V battery could become extremely dangerous.
No, do not attempt to use Boost Air to jump start a lithium battery. Lithium batteries are sensitive to how current is applied to the battery, jump starting a lithium battery could become extremely dangerous.
Yes, as long as the battery is a 12V Lead Acid battery.
There isn't a direct Boost-to-SAE adapter since the SAE cable isn't rated for the output of the Boost Air. You can install the eyelet cable alongside the SAE cable you have on your battery, then plug the device directly into the GBC007 when jump-starting.
No. While Boost Air can jump start your car battery it is not a battery charger. If you need to charge your car battery we recommend using a NOCO charger for charging and maintaining 6V or 12V batteries lead acid, AGM or Lithium batteries.
The AX65 includes multiple safety features:
- Over-Current Protection
- Open-Circuit Protection
- Over-Heating Protection
- Over-Charge Protection

It is normal for the AX65 to repeatedly stop and resume airflow as it gets closer to the set pressure. This behavior is part of the Dynamic Dwell feature, which helps ensure that the device does not overinflate the connected object and allows for more accurate pressure readings.
The AX65 is built with an Automatic Shut-off feature for ease of use. The compressor will turn "OFF" when the desired pressure has been reached, or if the battery voltage drops below 10.0V.
Automatic Shut-off will not occur in Manual Air Mode unless the maximum rated pressure of the product has been reached.
If AX65's Automatic Shuttoff does not activate as expected, make sure the cable connection is tight and there are no leaks in the system, and refer to the product's User Guide. Contact support if the problem persists.
NOCO Boost Air motors are brushed.
For vehicles with dual battery configurations, connect both the positive and negative clamps of Boost Air to the battery closest to the starter.
- If your batteries are in parallel, you can use two Boost Air units to double the starting power if needed.
- If your batteries are in series, you cannot use any 12V Boost. A 24V jump starter would be required.
Yes. Boost Air models are FAA-compliant and can be taken on a plane, however, they must be in your carry-on as lithium batteries are not permitted in checked luggage. All Boost Air models are under 100Wh which is the limit set by the FAA. For more information or current updates, please see the link below to the FAA guidelines. We also recommend contacting the airlines you are flying to see if they have additional restrictions.
AX65 is proudly designed in the USA and manufactured overseas to ensure our customers receive exceptional design and quality at the most affordable price.
This is to compensate for air loss while disconnecting, Boost Air will add slightly more air than it was set at. For example, you may see Boost Air end up at 37.0 PSI instead of the set pressure of 36.5 PSI to compensate for the .5 PSI that will escape while untwisting the air hose connection.
The recommended duty cycle for AX65 is 7 minutes at 30 PSI, followed by 53 minutes of rest.
The AX65 is designed to jump start 12-volt lead-acid batteries down to 3-volts. If your battery is below 3-volts, the Boost LED will be "OFF". This is an indication that the AX65 can not detect a battery. If you need to jump start a battery below 3-volts there is a Manual Override feature, which allows you to force "ON" the jump start function.
Yes. Boost Air will arrive partially charged. Fully charge the unit before first using it to ensure optimal performance.
Please charge the unit before storing it to elongate its lifetime. NOCO Boost Air should not be stored below -4ºF (-20ºC), and not exceed 122ºF (50ºC) for any reason. Storing outside of these ranges can cause damage to multiple crucial components of the device. Store at 77ºF (25ºC) for optimal longevity. Do not store outdoors. Instead, store in a dry indoor location with at least 0.50 inch (12.7 mm) of space around the product to allow for adequate airflow. Wrap the hose and disconnect cables to protect them during storage.
NOCO Boost Air can operate within the temperature range -4ºF to 122ºF (-20ºC to 50ºC). AX65 is equipped with thermal sensors that will prevent it from operating outside of this temperature range for your own safety.
Nothing, it is perfectly safe. Boost Air has built-in spark-proof sensors that prevent power from being delivered unless a battery is detected or the device is in Manual Override Mode.
When in Manual Override Mode: Do not allow the positive and negative battery clamps to touch or connect to each other, refer to the user guide for more information.
The REVERSE POLARITY error LED will illuminate, but it is perfectly safe and there won't be any sparks. With Reverse Polarity Protection, Boost Air will not deliver power unless connected to the battery correctly.
When in Manual Override Mode: Do not allow the positive and negative battery clamps to touch or connect to each other, refer to the user guide for more information.
No. Boost Air should be recharged in temperatures between 32ºF to 104ºF (0ºC to 40ºC). Remove from heat source and allow the battery to cool down before recharging.
No. Remove Boost Air from direct sunlight. The ambient temperature in a car can increase to 50°C (122°F) within just 10 minutes.
No, our product is equipped with advanced circuitry designed to maintain the battery in a safe state, provided the unit is not tampered with and is charged using a USB-C compliant charger. Do not attempt to modify, service, or tamper with the charging circuitry or bypass the Battery Management System (BMS). Any unauthorized actions will immediately void the product warranty and absolve NOCO of any liability for any resulting harm, damage, or injury, including risks of fire, electrical shock, or property damage.
The built-in lithium-ion battery is not user-replaceable and is designed to remain sealed within the unit. Do not attempt to replace, modify, or tamper with the battery under any circumstances. Handling a damaged or leaking lithium-ion battery is extremely hazardous and may result in serious injury, fire, or property damage. For disposal or assistance with a faulty unit, contact NOCO or refer to the contact information provided on the back of the unit. Any unauthorized attempts to service, alter, or replace the battery will immediately void the product warranty and release NOCO from any liability for resulting harm, damage, or injury.
The hose is 3 feet (0.91 m) long and is made of black EDPM with polyester fiber braiding for durability.
We always recommend checking in with your local laws, and regulations for proper disposal of your Lithium battery products, like the Boost Air. If you live in the USA or Canada, you can follow this link to see where to drop off the Lithium product for recycling in your area: https://www.call2recycle.org/locator/
Unfortunately at this time we do not manufacture cases for the Boost Air models. All Boost Air models come with a microfiber bag for storage.
If your positive and negative posts are too far away from each other, you can also connect to a negative ground on the vehicle chassis rather than the negative post.
Unfortunately, there are no extension cables available for the clamps on Boost Air products as extending the cables would reduce the starting power they produce.
Boost Air can be charged using any standard USBC to USBC cable like the ones many smartphones and tablets use. NOCO also offers USBC charging cables, go to XGrid Products to purchase one.
