Replacement Power Adapter for Maxtor OneTouch 4

This ABLEGRID AC adapter replaces the original charger for the Maxtor OneTouch 4 STM305004OTA3E1-RK. It supplies DC power from a 100-240V AC source at 50-60Hz. The barrel tip connector matches the drive's input. It suits users needing a new power supply for this specific external hard drive.

Non-OEM Upgrade with Safety Certifications

The unit is a non-OEM replacement carrying CE, FCC and RoHS certification. It adds over-voltage and over-heat protection not always present on older bricks. The 517% compatibility claim indicates broad spec alignment. The jump is worth it when the original adapter is lost, damaged or shows unstable output.

Simple Plug-In Installation

Installation requires only connecting the barrel tip to the drive and the mains plug to a wall socket. No drivers or configuration are needed. The main risk is ordering the wrong tip size or polarity; verify the DC output and connector dimensions before purchase. Ensure adequate ventilation during extended use.
