    How do you recharge it
    ByJun 20, 2026
    1 Answer | 
    Answer This Question

    The GB40 can be charged from any USB-C power source like your computer/laptop, a USB-C AC adapter, a 12V USB-C adapter, etc., in conjunction with the USB-C to USB-C cable provided with it (or any standard USB-C cable you may already own). The Boosts do not come with an AC Adapter to charge from the wall, as they are distributed globally and AC outlets change from region to region. However, the GB40 can use any USB-C AC Adapter like the ones many smartphones come with. To charge the unit, simply connect the included USB-C cable to the USB IN port on the GB40 and the other end to your preferred power source.

      Does it come fully charged

      Answer This Question

      No, federal laws regarding lithium batteries prohibits us from shipping the BOOST Jump Starters with a full charge. We strongly recommend fully charging the unit before first use.

        Can this charge a 2011 Honda Pilot?
        ByJan 24, 2026
        1 Answer | 
        Answer This Question

        The GB40 is a jump starter only, and cannot be used to charge or maintain a battery. See NOCO Genius Battery Chargers for that purpose. The 2011 Honda Pilot has a 3.5L gasoline engine, so the GB40 would be more than sufficient for jump starting that vehicle.

          I have a SUV with BCI Group Size 94R battery. Does this jumpstart device work on this size battery?

          Answer This Question

          if the battery is totally dead will the device still work ?

          By|Feb 2, 2026

            The Boost line of jump starters can be used on all 12V Lead-Acid batteries. These include Wet-Cell, Gel-Cell, AGM, AGM+, Maintenance Free, and EFB batteries. The Boost will also work with Calcium Calcium, Calcium-Lead, and some Lithium batteries. We have not tested all lithium battery types with our jump starters, and suggest you contact the battery OEM for guidance. As long as your Group 94R battery is one of the aforementioned chemistries, and your vehicle's engine is within the 6.0L gasoline/3.0L diesel range, the GB40 would be compatible.

              The Boosts do not come with an AC Adapter/Charger, as the unit is distributed globally and AC outlets change from region to region. However, the Boost can use any USB AC Adapter, like the ones many smartphones come with.

                how do you recharge the jump starter
                ByJun 12, 2025
                1 Answer | 
                Answer This Question

                The GB40 can be charged from any USB source, like your cell phone's USB wall charger, a computer or laptop USB port, or a 12V USB adapter for charging from a vehicle's 12V cigarette lighter-style port. They are not supplied with an AC charger because they are distributed worldwide, and outlet styles vary in every region, but the GB40 can use any USB AC adapter rated at 2.1A or less.

                    First accessory for daughter's new car
                    Initially, I wanted a duplicate of the long, heavy-duty 100% copper cables that have ridden in my trunk for the past 20+ years. Things have changed - now my daughter can refresh a flat battery w/o waiting for a (kind?) stranger to make the jump. Arrived half-charged to show how the lamp works. Cables have square/round fittings to avoid cross polarity. I hope it's a long time before she needs to use this.

                      Hold charge 6 to 8 months
                      With a full charge my unit Hold up to six to eight months charge. This is my second purchase unit the first one was smaller 500 Amp. I have had it for yrs. Even with one light showing it will jump my V8 Dodge Ram 03 expect to get no less greater service with this one 1000 Amp. This one will stay in my 2015 Dodge Ram. I probably wouldn't ever need it but it's good to help others in need.
