ASMAX T20 Jump Starter 7-in-1 3000A with Air Compressor, Power Bank & LED

The ASMAX T20 is a compact 7-in-1 roadside rescue tool that combines a 3000A jump starter, digital air compressor, power bank, LED flashlight and smart safety features in one portable unit.

Designed for drivers, outdoor enthusiasts and anyone who wants a small but powerful emergency kit, the ASMAX T20 pairs high peak current for jump-starting with a precise, auto-stop inflator and USB power output. Its rugged ABS housing and smart clamp protections make it practical for everyday use and unexpected roadside situations, while the bright display and multiple nozzles cover a wide range of inflation needs.

How powerful is the jump-start function and what vehicles can it handle?

The T20 delivers up to 3000A peak current and supports repeated starts per full charge, making it suitable for most 12V vehicle batteries. It is rated to assist engines up to 9.0L gas and 6.5L diesel, and provides many starts on a single charge when used within the recommended battery level and operating temperatures.

• Peak current: 3000A for instant boost
• Compatible with cars, SUVs, pickups, motorcycles, ATVs, boats and lawnmowers
• Supports up to 9.0L gas / 6.5L diesel engines
• Designed for 60 starts per full charge under typical conditions

What safety features protect me and my vehicle during jump-starting?

ASMAX built the T20 with smart clamps that guard against sparks and reverse polarity, plus multiple internal protections managed by intelligent circuitry. These measures reduce user error and extend the device’s life while helping protect vehicle electronics during a jump-start attempt.

• Spark-proof clamps and reverse-polarity protection
• Ten safety protections including overcurrent and short-circuit prevention
• UL and FCC certifications and durable, drop-resistant ABS housing

How accurate and versatile is the air compressor for tires and gear?

The built-in pump covers a wide 4–150 PSI range with a fast 35 L/min flow and an auto-stop feature linked to a backlit digital display. Set your target pressure in PSI, BAR, kPa or KG/CM and the unit automatically stops when reached, making inflation precise and hands-off.

• Auto-stop with 0.01 BAR display accuracy for consistent results
• Five inflation modes and five nozzle adapters for tires, sports balls and inflatables
• Rapid inflation: typical car tire (28–36 PSI) in about one minute
• Includes 50 cm extended hose for easier reach

What else does the T20 provide for road trips and emergencies?

Beyond boosting and inflating, the T20 doubles as a power bank with USB‑C output and a 400-lumen LED flashlight offering steady, flashing, and SOS modes. Its compact footprint and light weight make it easy to stow in a glove box or trunk, and the manufacturer supports it with a two-year warranty.

• USB-C device charging for phones and small electronics
• 400-lumen LED with multiple modes for roadside signaling and illumination
• Compact dimensions (7.09" x 4.02" x 1.97") and 1.40 lbs weight
• Rated for 1000+ battery cycles and wide operating temperatures

Who is this for? The ASMAX T20 is aimed at drivers, commuters and outdoor participants who want a single, portable device for battery rescues, accurate tire inflation and basic device charging. It’s helpful for anyone looking to simplify their emergency gear with a certified, easy-to-use tool that handles common roadside tasks without bulky equipment.
