NOCO Boost X GBX75 Jump Starter

No UL listing has been confirmed for the GBX75. The product specifications table shows 'Specification Met: energy' · notably, this does not include a UL claim, unlike the GB70 listing. No UL or ETL certification was found on the product listing, manufacturer specs page, or product manual. CE status is also unknown · not confirmed present or absent. The GBX75 is documented as having no confirmed third-party electrical safety certification at time of scoring. If a future UL Product iQ database lookup confirms a listing, the safety certification quality score and health score will be updated.

Yes. The GBX75 has a 60-watt USB-C Power Delivery port that supports both input and output at up to 20V/3A. This allows fast-charging of laptops, tablets, and phones with USB-C PD compatibility, and enables the unit itself to recharge in 1.8 hours from a PD-capable source. This is a significant upgrade over the GB70, which has a 10W standard USB-C port without Power Delivery.

The GBX75 has an integrated 60-second timer that automatically disengages the output after 60 seconds to conserve battery and manage thermal load from its high-voltage design. This delivers up to 12 jump starts per charge. There is a manual override button that bypasses the timer, but community users report that leaving the override active without active cranking can fully drain the unit and potentially prevent recharging · use the override only while actively cranking the engine.

The GBX75 includes a Cold Mode that pre-warms the internal lithium battery before delivering full cranking current in sub-freezing temperatures. At very low temperatures, lithium batteries deliver reduced current; pre-warming brings the cell closer to its operating range before the full load of engine cranking is applied. Community reports include a successful cold-weather start on a 2015 F-150 with a dead AGM battery at -10°C (14°F).

The Amazon listing for NOCO Boost X GBX75 Jump Starter carries a California Prop 65 warning. California requires this warning on a very wide range of manufactured goods — including electronics with wiring, solder joints, or plastic/metal housings — whenever trace exposure to any of roughly 900 listed substances (commonly phthalates or heavy metals) is possible, regardless of whether the specific product poses a meaningful health risk. As a passive electronics product, NOCO Boost X GBX75 Jump Starter has no Safety Data Sheet, so there's no chemistry breakdown to translate beyond that.
