NOCO Boost GB70 — 2000A UltraSafe
NOCO Boost GB70 — 2000A UltraSafe is editorial rank #5 in its category. The GB70 is the step up to 2000A: spark-proof, reverse-polarity-protected output that NOCO rates for engines up to 8.0L gas and 6.0L diesel, backed by 30,000+ owner ratings. You pay for the amp headroom; the smaller GB40 is the same UltraSafe system for about half the money if your engine doesn't need 2000A. Researched, not tested.

What are the closest alternatives?
…GET THE WINNER · Hulkman Alpha85 — $199.99 · 86
Buy on AmazonThe all-rounder for people who want the pack to double as a laptop or phone bank: Hulkman rates the Alpha85's 2000A for gas engines up to 8.5L and diesels up to 6.0L, and its 65W USB-C PD charges in and out. The 3.3-inch screen reports exact charge and fault state rather than making you guess at LED bars.
…SPEND LESS · GOOLOO GP4000 — $119.99 · 85
Buy on AmazonThe high-amp budget option: 4000A peak rated for all gas engines and diesels up to 10.0L, with SuperSafe clamp protection and a big enough cell to work as a dual-USB power bank. Note this is the GP model — GOOLOO's pricier GT4000S is the one with 100W two-way USB-C, which this does not have.
…SPEND MORE (+$105) · NOCO Boost GB150 — $299.95 · 74
Buy on AmazonThe step up from the GB70 when you are starting a big diesel — NOCO rates it 3000A against the GB70's 2000A, for engines up to 9.0L gas and 7.0L diesel.
…CONSIDER · AVAPOW A68 — $149.99 · 70
Buy on AmazonThe headroom option for big trucks and diesels: AVAPOW rates the A68 at 6000A peak and up to a 12L diesel, with an eight-layer clamp protection system and indicator lights that make a wrong connection hard to complete. It also works as a dual-USB power bank with a 3-mode LED light. Overkill for a commuter car, right-sized if you regularly start large diesel powerplants.
…CONSIDER · NOCO Boost GB40 — $99.95 · 79
Buy on AmazonThe glovebox standard for regular cars: NOCO rates its 1000A for gas engines up to 6.0L and diesels up to 3.0L, with the same spark-proof clamps as the pricier NOCO units. Skip it only if you run a large V8 or diesel that wants more amps.
