About NOCO
NOCO is a family-owned automotive electronics company founded in 1914 in Cleveland, Ohio, where it remains headquartered today. The company got its start when founder Joseph Henry Nook, a local tire and battery distributor, developed NCP2, the world's first battery corrosion preventative -- a product still sold more than a century later. NOCO's modern lineup has grown well beyond that original grease spray into Boost lithium jump starters, GENIUS smart battery chargers, portable air inflators, and lithium batteries, engineered in-house by dedicated industrial design, electrical engineering, and testing teams split between the Cleveland headquarters and a research and development center in Phoenix, Arizona.
NOCO's patented UltraSafe clamp technology, which detects and mitigates connection errors before a jump starter can spark or reverse-polarity a vehicle's electronics, has become a category-defining safety feature that independent reviewers single out repeatedly. The NOCO Boost GB40 has been named a top pick by outlets including Wirecutter and CNN Underscored, and carries well over 100,000 verified Amazon ratings at a 4.6-star average -- one of the largest review bases of any jump starter sold online. Verified long-term owners commonly report 5 to 7-plus years of reliable service from NOCO's GB-series jump starters.

Why we recognized NOCO
The RevRated Top Brand recognition isn't paid for and can't be applied for. We award it to the brands whose products consistently stand out in our hands-on category reviews. NOCO earned it on the strength of the products below, evaluated the same way every product on this site is: bought, run on real vehicles, and judged on merit.
NOCO products we rated highly
NOCO Boost GB40 1000A UltraSafe Lithium Jump Starter
Independent reviewers have repeatedly named the GB40 the jump starter to buy, and its conservative 1000A rating reflects real deliverable cranking power rather than an inflated peak number. UltraSafe spark-proof clamps won't arc or reverse-polarity a vehicle's electronics, and at 128,000-plus Amazon reviews and a 4.6-star average, it carries the deepest validation of any compact jump starter we tested -- all in a 2.4-pound body that fits in a glovebox.

NOCO Boost X GBX45 1250A UltraSafe Lithium Jump Starter
The step-up NOCO for drivers who want more charging speed without leaving the brand's proven UltraSafe platform: 60W USB-C Power Delivery recharges the unit from empty in 48 minutes and can fast-charge a laptop in the field, while its 1250A conservative rating follows the same deliverable-power engineering as the GB40. Verified owners report a 5 to 7-plus year lifespan from the same GB-series design.

NOCO GENIUS10 10A Smart Battery Charger
Built for large-format batteries in trucks, SUVs, and diesel vehicles, the GENIUS10's 10A output halves the recovery time of a standard 5A charger on a Group 65 battery. Full multi-chemistry support for lead-acid, AGM, Gel, and LiFePO4 is standard, and Force Mode can recover a battery sitting at a full 0 volts that many smart chargers refuse to touch.
