Handle a dead battery on your own
A dead battery can stop the day before it starts. The GBX155 is a portable 12V jump starter made to help you get a compatible vehicle started without needing another vehicle for a jump. Its 4250A rating supports larger compatible engines, including up to 10.0L gasoline and 8.0L diesel.
This is a jump starter first, not just a backup charger. The included heavy-duty booster clamps connect the unit to a compatible 12V battery, and NOCO lists spark-proof technology with reverse polarity protection. Those details matter when you want a dedicated tool ready for the moment a vehicle will not start.
Once the jump start is handled, the GBX155 also works as a 60W USB-C power bank for compatible devices. USB-C power delivery works both in and out, so you can recharge the unit or charge devices such as phones, tablets, laptops, and wearables. The included microfiber storage bag helps keep the kit packed together.
Use the included USB-C charging cable to recharge the jump starter so it is ready when you need it.
Connect to a compatible battery
