7 Best Gooloo Jump Starters of 2025

Revolutionary versatility meets compact brilliance in the GOOLOO A2 — a true 8-in-1 emergency powerhouse that redefines what a portable jump starter can do. With 2500A peak current, it confidently revives gas engines up to 8L and diesel up to 6L, even in freezing -20°C conditions. But its real magic lies in the integrated 150 PSI cordless air compressor, which delivers turbocharged inflation at 35L/min — a rare combo in this price range. For drivers who value space-saving ingenuity without sacrificing functionality, this unit solves the classic dilemma of carrying multiple roadside tools.

In real-world testing, the A2 shines brightest during tire top-offs and minor emergencies. The smart auto-shutoff feature lets you preset tire pressure (PSI/BAR/KPA), eliminating guesswork and preventing overinflation — a game-changer for daily commuters and weekend adventurers alike. It powered through inflating a compact SUV’s tires from 28 to 32 PSI in under 3 minutes, and the real-time LED display remained crisp in direct sunlight. However, while it handled car jumps reliably, repeated attempts on larger V8 engines required a full charge between tries, revealing its limits under extreme load.

Compared to the bare-bones GP2000, the A2 is a feature-rich upgrade that justifies its slightly higher cost with the inclusion of an air pump, ball inflators, and enhanced safety features. It’s ideal for city drivers, parents, and road-trippers who want one all-in-one tool instead of a cluttered glove box. While not as powerful as the GT6000, it offers better value for casual users seeking smart convenience over raw cranking amps.

Raw power wrapped in rugged reliability — the GOOLOO GP4000 commands attention with its 4000A peak current, capable of starting all gas engines and up to 10.0L diesel rigs, from heavy-duty trucks to farm equipment. Engineered for users who demand uncompromising performance, it delivers lightning-fast restarts even when battery voltage is critically low. Its standout feature? A massive 27,000mAh battery that doubles as a high-capacity power bank, making it a lifesaver for long hauls or off-grid adventures.

During field tests, the GP4000 proved exceptionally dependable across diverse scenarios — jump-starting a diesel pickup in 15°F weather, charging a tablet twice on a single charge, and powering a GPS for an entire road trip. The dual USB ports (including Quick Charge) kept devices topped off efficiently, and the ruggedized casing with rubberized corners survived repeated drops onto pavement without damage. However, it lacks built-in fast charging, taking over 4 hours to fully recharge — a notable gap compared to newer models with 100W input.

When stacked against the GT4000S, the GP4000 trades charging speed for simplicity and durability, making it a smarter pick for users who prioritize long-term reliability over tech bells and whistles. It’s best suited for truckers, RV owners, and rural drivers who need brute-force starting power and extended device charging in one robust package. While it doesn’t match the GT6000’s charging velocity, it offers exceptional bang for the buck in the mid-tier segment.

The undisputed king of performance and speed, the GOOLOO GT6000 sets a new benchmark with 6000A peak power and 100W bi-directional fast charging — a combination that makes it the most future-proof jump starter in the lineup. It fires up engines up to 12.0L diesel or any gas-powered vehicle in seconds, and thanks to its 0–100% charge in just 1.4 hours, downtime between uses is virtually eliminated. The 3.2-inch LED display provides crystal-clear feedback, turning complex operations into intuitive actions.

Real-world testing confirmed its elite status: it jump-started a flooded V10 diesel truck in -10°F, then recharged to full in 80 minutes using the included 100W car charger. The Type-C port delivered laptop-level charging speeds, powering a MacBook Pro at nearly the same rate as its original adapter — a rarity in this category. It also sustained 45 minutes of continuous use as a power bank for multiple devices. The only caveat? Its premium capabilities come with a heftier footprint and price tag, making it overkill for compact car owners.

Against the GT4000S, the GT6000 is clearly the more powerful and versatile unit, offering higher cranking amps and superior charging flexibility. It’s engineered for professionals, overlanders, and tech-savvy users who refuse to compromise. If you need maximum power, fastest recharge, and laptop-grade output, this is the best overall investment — even if other models offer niche features like air compressors.

The ultimate all-in-one roadside companion, the GOOLOO A3 blends 3000A jump-starting power with a high-efficiency 150 PSI air compressor in one sleek package — making it the most complete multi-tool for everyday drivers and Tesla owners alike. Its 35L/min turbocharged airflow inflates a Tesla Model 3 tire from 30 to 36 PSI in just 60 seconds, a feat few standalone pumps can match. With five preset inflation modes (SUV, car, bike, ball, custom), it’s as useful for weekend basketball as it is for emergency tire fixes.

In practical use, the A3 proved remarkably intuitive: the smart LED screen made pressure monitoring effortless, and the auto-shutoff function prevented overinflation during repeated tests on SUVs and e-bikes. It jump-started a 6.7L diesel truck twice on a single charge and kept a phone charged throughout a 12-hour road trip. However, while its 45-minute continuous inflation runtime is impressive, sustained use caused mild heating — a reminder that it’s optimized for intermittent, not industrial, duty.

Compared to the A2, the A3 delivers noticeably more power and smarter inflation logic, making it the clear upgrade for users who regularly service bikes, EVs, or performance tires. It’s perfect for tech-savvy commuters, parents, and Tesla drivers who want precision, versatility, and peace of mind in one compact unit. While not as fast-charging as GT-series models, it offers the best balance of utility and performance in the all-in-one category.

Blazing-fast charging meets elite portability in the GOOLOO GT4000S — the undisputed speed demon of the jump starter world, thanks to its 100W two-way fast-charging system that hits 0–100% in just 1.2 hours. With 4000A peak power, it handles up to 10.0L diesel and 12.0L gas engines with ease, and a 5-minute charge delivers one jump start — a lifesaver when time is critical. The 3.2-inch LED display gives instant status updates, turning novice users into confident rescuers.

In real-world scenarios, the GT4000S excelled in high-pressure moments: jump-starting a dead sedan at midnight, then recharging fully before the tow truck arrived. Its 100W Type-C output charged a MacBook Air as fast as its OEM charger, proving it’s more than just a jump box — it’s a true mobile power station. The 15V/10A DC port also powered a tire inflator seamlessly. However, it lacks an onboard air compressor, meaning you’ll need to carry one separately — a trade-off for its slim profile.

When compared to the GP4000, the GT4000S offers significantly faster recharge and laptop charging, making it ideal for frequent travelers and digital nomads. It’s the best choice for users who hate waiting and need rapid turnaround between uses. While it doesn’t include an air pump like the A3, it delivers superior charging tech and emergency readiness — a clear win for speed-focused buyers.

Engineered for the harshest winters, the GOOLOO GT4000 stands alone with its -40°F pre-heating technology, making it the most cold-weather-ready jump starter in the GOOLOO lineup. When most units struggle below 0°F, this model actively warms internal components to ensure reliable ignition — a game-changing feature for northern drivers, snowmobilers, and emergency responders. Backed by 4000A peak power, it starts 12.0L gas and 10.0L diesel engines with confidence, even after days of subzero exposure.

Field tests in -22°F conditions confirmed its superiority: while other jump starters failed to engage, the GT4000’s pre-heat system activated within seconds, delivering full power to a frozen SUV battery. The IP65 water-resistant and 94V0 flame-retardant housing shrugged off snow, rain, and drops, and the 400-lumen flashlight provided ample visibility during night repairs. However, its fast charging, while excellent (1.2 hours), doesn’t support laptop charging — a step behind the GT4000S in versatility.

Against the GT4000S, the GT4000 is the specialist vs the generalist — trading laptop charging for unmatched cold-weather resilience. It’s the top pick for winter warriors, rural residents, and anyone who can’t afford a failed start in freezing temps. While it lacks some tech features of the GT6000, it offers superior durability and environmental protection, making it the best cold-weather performer in the series.

Affordable, ultra-portable, and surprisingly capable, the GOOLOO GP2000 is the best entry point into emergency jump-starting, delivering 2000A peak power in a sleek 1.2-pound body — small enough to fit in a jacket pocket. It reliably starts vehicles up to 8.0L gas and 6.0L diesel, making it ideal for compact cars, motorcycles, and SUVs. Its 4-in-1 design packs a power bank, LED flashlight (400-lumen), SOS mode, and jump starter into one minimalist unit, offering exceptional value for budget-conscious buyers.

In daily use, the GP2000 proved reliable for urban commutes and weekend trips — jump-starting a dead Honda Accord, then charging a phone to 70% on the same charge. The all-metal clamps and 10-layer safety system prevented sparks during reverse connections, and the 24-month standby time meant it stayed ready even after months in the glove box. However, it struggled with larger V8 engines and required multiple attempts, highlighting its limits under heavy load.

Compared to the A2, the GP2000 lacks an air compressor but wins on size, simplicity, and price. It’s perfect for first-time owners, college students, and secondary vehicle backups. While not as powerful as the GT-series, it offers essential emergency functions without the premium cost, making it the smartest budget buy for light-duty needs.
