GOOLOO A5 4000A Jump Starter with 160 PSI Air Compressor, 20,000mAh Power Bank & 45W USB-C

The GOOLOO A5 is a compact 4-in-1 roadside power kit that combines a 4000A jump starter, a 160 PSI air compressor, a 20,000mAh power bank, and a bright LED light into one rugged unit.

When your vehicle battery dies or a tire goes soft, you want a single, reliable tool that gets you moving quickly. The GOOLOO A5 packs high peak cranking power, a fast inflator, and honest battery capacity into a portable package sized to fit in a trunk or under a seat. Its clear sunlight-readable display and built-in 45W USB-C output make it useful for more than just emergencies—it's a practical multi-use device for drivers, outdoor enthusiasts, and fleet operators.

How does the A5 handle jump-starting modern vehicles?

Equipped with GOOLOO’s JUMPCORE technology, the A5 supplies up to 4000 amps of peak current to restart most 12V engines, including large gasoline engines and many diesel models. SUPERSAFE protections reduce risk during connection and operation. A BOOST mode helps when the battery voltage is very low, improving chances of a successful start in demanding conditions.

• 4000A peak current for quick engine starts
• Works on most 12V gas engines and diesels up to 10.0L
• SUPERSAFE system minimizes sparks and reverse-connection risks
• BOOST setting for deeply discharged batteries

How fast and versatile is the built-in air compressor?

The A5's upgraded 25 mm motor pushes air up to 160 PSI for fast, real-world inflation. It fills common passenger and pickup tires quickly—examples include a full-size pickup tire increasing several PSI in minutes and a sedan tire topping up in under a minute. Preset modes and auto-stop remove guesswork and prevent over-inflation for tires, sports equipment, and inflatables.

• 160 PSI max pressure with a high-efficiency 25 mm motor
• Five inflation modes and five nozzle adapters included
• Auto-stop on reaching preset pressure for safe inflation
• Capable of tires, motorcycles, bicycles, balls, and small inflatables

What real-world battery and charging performance can I expect?

GOOLOO specifies an actual 20,000mAh battery capacity—stated honestly rather than inflated—enough for dozens of starts and multiple device top-ups. The integrated 45W USB-C output charges phones, tablets, and USB-C laptops quickly during roadside waits. A single full charge supports many jump starts, extended pump use, and long LED light runtime depending on the mode.

• 20,000mAh rated capacity for transparent performance
• One charge can support up to 50 engine starts and ~50 minutes inflation
• Built-in 45W USB-C cable for fast device charging (output-only)
• LED light provides extended runtime—up to 99 hours in low modes

What safety features and user conveniences are included?

The A5 integrates safety systems and user-friendly controls to make roadside tasks straightforward. A sunlight-readable color display shows inflator progress and battery status, while the smart jumper cable prevents common hazards. The kit includes a carrying bag and accessory set that makes storage and deployment intuitive.

• Sunlight-visible 2000-nit color display with rotating status ring
• Smart jumper cable for safer, controlled connections
• Rugged, compact footprint (8.98 × 5.55 × 2.40 in) for trunk storage
• Full accessory kit and 18-month warranty for peace of mind

Who this is for: drivers who want more than a basic booster — small-fleet owners, pickup and SUV drivers, frequent travelers, and anyone who values fast inflation and honest battery specs. If you need a durable, multi-purpose roadside tool that combines high starting power with a heavy-duty inflator and real-world battery life, the GOOLOO A5 is built to be a dependable trunk companion.
