EZRED MS4000 Automotive Memory Saver with Built-In Charger – Black

Meet the EZRED MS4000 Automotive Memory Saver with Built-In Charger, a compact tool designed to safeguard your vehicle’s essential memory during battery work. It plugs directly into the OBDII port, delivering power and preserving drive-ability codes and settings when the starter battery is disconnected.

Key advantages go beyond simply powering a device. The MS4000 stores critical information like anti-theft radio codes, clocks, and keyless entry system settings, helping you avoid the hassle of re-entering preferences after battery service. A built-in 12-volt, 4.5Ah sealed lead-acid battery is included inside the unit, ensuring the circuit remains energized even when the main battery is removed.

Core features at a glance

• Memory saver & charger: The MS4000 saves drive-ability codes and vehicle settings when you disconnect or replace the starter battery, while simultaneously charging its internal battery.
• OBDII direct connection: The direct wired OBDII connector plugs into the vehicle’s port, enabling seamless power delivery and data retention.
• Protection & indicators: A 4-amp circuit breaker guards the unit, while green and amber LEDs signal connection status and when replacement might be needed.
• Broader memory preservation: It safeguards radios, clocks, keyless entry systems, alarms, GPS memory, TPMS, and other memory-dependent functions that can be affected during service.

Real-world use cases highlight its practicality. During battery maintenance or starter replacements, the MS4000 can reduce setup time by maintaining important vehicle memory, potentially reducing post-work reprogramming tasks. The built-in battery helps maintain power even if the main battery connection is briefly interrupted, while the small, portable form factor makes it easy to carry in a tool kit or service bay.
