Schumacher Wheeled 4-in-1 6A Charger and 150A Starter - Reliable Power

Our review of the Schumacher SC1364a finds it best suited to home mechanics and small shops that need a durable, all-in-one battery service tool. The unit combines a powerful 150-amp engine starter with a 20-amp boost and a 6-amp to 2-amp charging/maintaining mode, so the biggest reason to buy is clear: this is a practical workhorse for repeatedly reviving and maintaining 12V batteries across automotive and marine applications. It is not a lightweight trickle pack for casual users, but a heavy-duty, AC-powered solution for anyone who wants one device to start, charge, maintain, and recondition batteries.

Key Features

• 4-in-1 device: Starts, charges, maintains, and reconditions 12V batteries so you can use one tool instead of multiple chargers and starters.
• Immediate starting power: The 150-amp engine starter delivers quick jump starts for cars, trucks, SUVs, and marine engines when you need fast recovery.
• 20A boost charge: A dedicated boost mode helps revive deeply discharged batteries faster than trickle-only chargers.
• Smart trickle charge: The 6A to 2A maintenance mode safely holds batteries at charge over long storage periods without overcharging.
• Battery reconditioning: Advanced desulfation mode helps extend battery life and improve performance by addressing sulfation on lead-acid batteries.
• Heavy-duty construction: Steel case, solid wheels, a retractable handle, and heavy clamps make the unit suitable for workshop and garage environments.

Who It's For

This Schumacher is ideal for owners of cars, trucks, ATVs, motorcycles, and marine craft who need a robust, AC-powered charger and starter that can be wheeled around a garage. It works well for seasonal vehicle owners who need a safe long-term maintainer and for operators who occasionally face dead batteries and want a 150-amp starter on hand.

It is less suited to those who want a small, battery-powered portable jump starter for roadside use, since the unit must remain plugged in while operating and is relatively heavy. Buyers looking for a lightweight, ultra-budget charger may also want to look elsewhere.

Pros & Cons

Pros

• Combines starter, boost charge, trickle maintainer, and reconditioning in one unit for versatile shop use.
• 150A starting and 20A boost provide fast recovery for dead batteries and larger engines.
• Smart trickle function keeps 12V batteries safe in long-term storage without overcharging.
• Sturdy build with wheels and a retractable handle for easier movement around a garage.

Cons

• Some users report mixed durability and build quality over time, so it may not meet every buyer's expectations for long-term reliability.
• Requires AC power while in use, so it is not a portable, battery-powered jump starter for roadside emergencies.

Specifications

Our Verdict

The Schumacher SC1364a is a solid choice for garage owners and small shops that want a single, heavy-duty unit to start, charge, maintain, and recondition 12V batteries. Its 150A starter and 20A boost deliver real starting power and quick recovery, and the smart trickle mode makes it useful for seasonal storage. Buyers seeking portability or the lowest possible price should consider alternatives, but for workshop reliability this unit represents good practical value.
