Product Overview
The NOCO Boost X GBX155 is a portable lithium-ion jump starter designed for 12-volt lead-acid vehicle batteries. This configuration is identified by manufacturer part number GBX155 and UPC 046221200096. It is rated for up to 4,250 amps of peak starting current and is intended for gasoline engines up to 10.0 liters and diesel engines up to 8.0 liters.
The GBX155 combines vehicle jump-starting capability with an internal 99 Wh lithium-ion battery, USB power functions, and an integrated flashlight. Its USB-C Power Delivery interface supports charging the jump starter and supplying power to compatible portable electronics. Safety functions include spark-resistant connection technology and reverse-polarity protection. The housing carries an IP65 ingress-protection rating for resistance to dust and water exposure under the conditions covered by that rating. Because jump starters handle high electrical current, users should follow the manufacturer’s connection, charging, temperature, and battery-safety instructions.
