Nothing, it is perfectly safe. Boost X has built in sensors that prevent power from being delivered, unless a battery is detected.

The error LED will illuminate, but it is perfectly safe and there won't be any sparks. With Reverse Polarity Protection, Boost X will not deliver power unless it is connected to the battery correctly.

NOCO Boost X models carry a rating of IP65 with the port covers closed, which means they can be exposed to water without any issues, however, but they cannot be submerged in water.

NOCO Boost X has a one-year limited warranty. Visit our Support Page to learn more about Warranty or find the User Guide to your specific Boost X model.

NOCO Boost can operate within the temperature range -4ºF to 122ºF (-20ºC to 50ºC). Boost X is equipped with thermal sensors that will prevent it from operating outside of this temperature range for your own safety.

NOCO Boost X should not be stored below -4ºF (-20ºC), and not exceed 122ºF (50ºC) for any reason. Storing Boost X outside of these ranges can cause damage to multiple crucial components of the jump starter. This applies to all Boost models.

No. Boost X 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.

The USB-C IN/OUT port utilizes Power Delivery 3.0 technology capable of receiving/delivering up to 60W. The time to recharge a GBX45 will differ based on the discharge level and the power source used. Actual results may vary due to battery conditions.

Boost X is equipped with Fast Charge technology that allows it to be recharged at a rate of up to 60W. A compatible charger, capable of 60W USB-C Power Delivery 3.0, is required to fully utilize this feature. The Fast Charge LED will illuminate when rate of charge exceeds 15W, indicating USB Power Delivery 3.0 is active.

All Boost X models can hold 70% of its rated capacity for up to one year. For optimal performance, we recommend charging the device at least every 4-6 months, after initial charge.

Yes. Boost X is USB-C rechargeable, so it’s not directly tied to the electrical service of your country (i.e. 120V or 220V). Use an AC to USB-C adapter or 12V to USB-C adapter to charge your device. A 12V USB-C Car Charger will work in any country or vehicle with a 12V port.

Boost X can recharge any device that uses USB or USB-C. This includes all generations of smartphones on the market, as well as HD action cameras, tablets, music players, headphones, earbuds, wireless speakers and more.

The provided USB-C cable is 24" (61 cm) in length. Boost charges with a standard USB-C port, so if a longer or short cable is prefered then the provided cable can be replaced with any compatible USB-C cable.

NOCO Boost X can only jump start 12V lead acid batteries. This includes wet, gel, maintenance free, enhanced flooded battery, and absorbent glass mat batteries.

Check out NOCO Boost Max to learn more about jump starting 24V batteries.

Boost jump starters are compatible with the starting-battery in hybrid vehicles as long as the starting-battery in question is a 12V Lead-Acid battery. These include Wet-Cell, Gel-Cell, AGM, AGM+, Maintenance Free, and EFB batteries. Boost will also work with Calcium-Calcium and Calcium-Lead batteries. As long as the unit is used on a 12V ignition system for a gas or diesel engine and on one of the aforementioned battery types, it will work.

Yes. Boost X can jump start any vehicle with a 12V lead acid battery like a car, boat, motorcycle, ATV, lawn mower, RV, tractor, truck and more.

Yes. Boost X will arrive partially charged. Fully charge the unit before first using it to ensure optimal performance.

No. The 12V ports in a car are current limited at 8 Amps. Boost X delivers a maximum range of 1,000A to 4,250A, depending on your model, which would cause severe damage to the port. However, there is no way to connect this product to the 12V port, so there is no risk of this happening.

No. Boost X is only designed for 12V vehicles. Jump starting a 6V battery could become extremely dangerous.

No. Lithium batteries are sensitive to how current is applied to the battery. Jump starting a lithium battery could become extremely dangerous.

No. Remove Boost X from direct sunlight. The ambient temperature in car can increase up to 50ºC (122ºF) within 10 minutes.

No. We do not replace the batteries or repair the units, but replace the whole unit if it tests faulty.

No. While Boost X can jump start your car battery it is not a battery charger. If you need to charge your car battery we recommend using NOCO Genius for charging and maintaining 6V or 12V batteries lead acid, AGM or Lithium batteries.

If Boost X is not detecting the battery it is possible the voltage is too low to detect. Boost X is designed to jump start 12-volt lead-acid batteries down to 2-volts. If your battery is below 2-volts, the Boost LED will be "Off". This is an indication that Boost X can not detect a battery. If you need to jump start a battery below 2-volts there is a Manual Override feature, which allows you to force "On" the jump start function.

Yes. All Boost X models are FAA compliant and can be taken on a plane, however they have to be in your carry-on. No-Lithium batteries are allowed to be checked in luggage. All Boost X models are under 100Wh which is the limit set by the FAA. For more additional information, or for 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 any additional restrictions.

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. You can install the GBC007 eyelet cable alongside the SAE cable you have on your battery, then plug the GBX45 directly into the GBC007 when jump-starting. GBC007 has an included X-Connect adapter which can be plugged into the cable and plug a compatible NOCO Genius Battery Charger into the adapter for charging and maintenance.

No. Boost X does not have a 12V output connection. Boost X can only power USB and USB-C powered devices.

For vehicles with dual battery configurations, connect both the positive and negative clamps of Boost X to the battery closest to the starter.

• If your batteries are in parallel, you can use two Boost 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.

Check out NOCO Boost Max to learn more about jump starting 24V batteries.

Boost X jump starters have built-in overcharge protection and can be left on a charger at all times.

NOCO does not individually sell the USB-C charging cable like the one provided with the unit. Boost X can be charged using any standard USB-C cable like the ones many smartphones and tablets use.

NOCO does sell USB-C Fast Charge accessories that could replace the USB-C cable. Learn about Fast Charge.

Unfortunately, there are no extension cables available for the clamps on Boost products as extending the cables would reduce the starting power they produce. 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.

We always recommend checking in with your local laws, and regulations for proper disposal of your Lithium battery products, like the Boost. 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:
