Picture this: you are running late for an important meeting, and your car battery is completely dead. Or maybe you are on a long road trip and notice a tire pressure warning light on your dashboard. In both scenarios, you need a reliable tool that can get you back on the road quickly. This GOOLOO A5 jump starter review explores a versatile 6-in-1 device that aims to solve both problems and more. We evaluated it alongside several top contenders from NOCO to help you decide which portable jump starter is right for your vehicle and your peace of mind.
Whether you drive a compact sedan, a full-size pickup, or an SUV, having a capable jump starter in your trunk can save you time and stress. We have reviewed dozens of models across various categories, including the best portable jump starter for car battery options, to bring you this focused comparison. Let us dive into what makes the GOOLOO A5 stand out and how it compares to other powerful units.
Buying Guide
Peak Current and Engine Compatibility
The most critical specification for any jump starter is its peak current rating, measured in amps. This number determines which engines the device can reliably start. For a standard 4-cylinder car, a unit with 1000 to 1500 peak amps is usually sufficient. However, if you own a large V8, a diesel truck, or an RV, you will want a model with at least 3000 to 4000 peak amps.
The GOOLOO A5 delivers 4000 peak amps, making it suitable for nearly all gas engines and diesel engines up to 10.0 liters. This puts it in the same league as the NOCO Boost GBX155, which offers 4250 peak amps but at a much higher price point. For most drivers, 4000 amps provides a generous safety margin for cold weather starts and deeply discharged batteries.
Additional Features: Air Compressor and Power Bank
A dedicated jump starter is great, but a multi-functional unit can replace several separate tools in your trunk. The GOOLOO A5 includes a built-in air compressor that can inflate tires up to 160 PSI, which is a standout feature. It also functions as a power bank with a 45W USB-C output cable, allowing you to charge your phone, tablet, or even a laptop.
In contrast, most NOCO models like the GB40 or GB50 focus solely on jump-starting and device charging, without an integrated inflator. If you frequently need to top off tires or inflate sports equipment, the GOOLOO A5 offers exceptional value.

Safety and Build Quality
Safety should never be an afterthought when dealing with high-current battery connections. Look for features like spark-proof technology and reverse polarity protection. Both GOOLOO and NOCO incorporate robust safety systems. The GOOLOO A5 uses the SUPERSAFE system with multiple protection layers, while NOCO models feature their patented UltraSafe technology.
Build quality also matters for long-term durability. The GOOLOO A5 has a rugged body with a sunlight-readable display, making it easy to use in bright conditions. NOCO units, like the GB40, are IP65-rated for water and dust resistance. For a comprehensive overview of top performers across all price points, visit our best rated car jump starter page.
Charging Speed and Battery Capacity
How quickly a jump starter recharges itself can be a deciding factor, especially if you need to use it multiple times in a short period. The GOOLOO A5 has a 20,000mAh rated capacity and can support up to 50 engine starts on a single charge. It also recharges via USB-C, though not as fast as some specialized units.
The GOOLOO GT4000S, on the other hand, supports 100W two-way fast charging, allowing it to fully recharge in just 1.2 hours. If rapid self-charging is a priority, that model might be a better fit. For most users, the A5’s balance of capacity and recharge speed is more than adequate for occasional use. Explore more options in our Jump Starters category.
Final Thoughts
After evaluating all eight products, we believe the GOOLOO A5 Jump Starter with Air Compressor offers the best combination of power, versatility, and value for most drivers in 2026. Its 4000A peak current, built-in tire inflator, and 45W USB-C output make it a true all-in-one roadside companion. For those who prioritize a premium, dedicated jump starter with higher peak current and do not need an inflator, the NOCO Boost GBX155 4250A UltraSafe Jump Starter is an outstanding choice with exceptional build quality and fast charging capabilities. Both units will reliably get you out of a bind, but the GOOLOO A5 delivers more features for a lower investment.

Can the GOOLOO A5 jump start a diesel truck?
Yes, the GOOLOO A5 is rated for diesel engines up to 10.0 liters, making it suitable for most pickup trucks, vans, and even some larger RVs. Its 4000A peak current provides ample power for cold starts and deeply discharged batteries.
How long does it take to inflate a car tire with the GOOLOO A5?
In our evaluation, the GOOLOO A5 inflated a standard 195/65 R15 sedan tire from 30 PSI to 36 PSI in about 30 seconds.
