The Boost X GBX155 jump starter delivers 4250A peak current for 10.0L gasoline and 8.0L diesel engines, making it a reliable emergency tool for car owners, off-road enthusiasts, and construction vehicle operators.
It features a one-button start design with a high-definition LCD display showing battery power, startup status, and fault indicators. The unit is compact and lightweight, includes a carrying case, and has a built-in LED emergency light with constant, strobe, and SOS modes.
It recharges in 1.8 hours via USB-C Power Delivery and can gain enough power for a jump start in 5 minutes from a depleted battery. The 60-watt USB-C port charges phones, tablets, laptops, and more, and the unit can act as a portable power bank. The integrated 400-lumen LED flashlight has 7 light modes.
The box includes the GBX155 jump starter, heavy-duty clamps, USB-C charging cable, and microfiber storage bag. It is backed by a 1-year warranty and engineered in the USA.
Reviews imported from our previous store / verified customer feedback
★★★★☆
Engine Ratings Are Clearly Defined
Support up to 10.0L gasoline and 8.0L diesel made choosing the correct jump starter much less ambiguous.
★★★★☆
Portable Despite Serious Output
It fits with our roadside equipment without the bulk of older boosters, although I check its charge regularly.
