Jump Starter with Air Compressor - Portable 3500A Jump Box for Cars

In this review the LERTIN Jump Starter with Air Compressor earns its place as a compact all-in-one emergency kit for drivers who want reliable starting power and fast tire inflation without extra gear. The unit's single biggest draw is its combination of a high-capacity 3500A peak jump starter and a 150 PSI turbo air compressor in a lightweight 1.8 lb package, which makes it useful for anyone who values quick, space-saving roadside help. The review focuses on real-world use: starting larger engines, inflating tires quickly, and using the built-in power bank and lights when a phone or visibility is needed.

Key Features

• Powerful jump start: 3500A peak current can start 12V vehicles up to about 9.0L gas or 8.0L diesel engines, letting users get back on the road quickly.
• Fast inflation: Turbocharged 35 L/min pump with up to 150 PSI fills a tire to 20 PSI in roughly 2 minutes and stops automatically when the set pressure is reached.
• Multi-mode display: Large LCD shows real-time pressure in PSI, BAR, KPA, or KG/CM2 and supports five inflation modes for cars, motorcycles, bicycles, balls, and pressure protection.
• Portable power bank: Built-in 12000 mAh battery and USB quick charge output recharge phones and small devices on the go and save time during emergencies.
• Emergency lighting: 300 lumen LED provides continuous white light, strobe and SOS red modes for roadside warning or camping use, lasting up to 48 hours in lower modes.
• Smart safety clamps: Intelligent battery clips auto-detect connection, show a steady green when correct, and add 10 built-in protections to reduce risk during jump starts.

Who It's For

This unit is aimed at drivers who want a compact, multi-function emergency tool: commuters, long-distance travelers, and weekend adventurers who may face dead batteries or low tires and prefer a single portable device stowed in a trunk. It is particularly useful for owners of larger gasoline and diesel vehicles who need higher peak cranking power.

Those who should look elsewhere include users who require continuous high-volume inflators for heavy equipment or professional mechanics who need industrial-grade pumps and chargers; this is a consumer-grade portable solution optimized for occasional emergency use rather than heavy-duty commercial use.

Pros & Cons

Pros

• High peak current and proven cold-start range for up to 9.0L gas or 8.0L diesel engines.
• Rapid inflation with four nozzle options and automatic shutoff for precise pressure control.
• Lightweight design with storage bag and multiple lighting modes adds real roadside utility.

Cons

• Air pump should not be used continuously and requires cooldown and periodic recharging for long-term storage, so it is not suited for heavy repeated inflation tasks.

Specifications

Our Verdict

The LERTIN Jump Starter with Air Compressor is a practical, space-saving emergency tool that combines strong cranking power, a quick air pump and useful lighting in a lightweight package. For most drivers it represents good value because it reduces the need for separate devices and performs reliably for occasional roadside starts and inflations, provided users follow the guidance on pump duty cycle and periodic recharging during storage.

Frequently Asked Questions

Can this start large engines?
Yes, the unit delivers up to 3500A peak and is designed to start up to about 9.0L gas and 8.0L diesel engines.

How does the tire inflator stop at the right pressure?
The built-in LCD and selectable units let you set the target pressure and the pump will automatically stop when that pressure is reached.

Is it safe to use if clamps are reversed?
The smart battery clips provide visible alarms and multiple protections, including reverse polarity protection, so incorrect connections will not damage the vehicle or the user.
