Replacement AC adapter for Maxtor OneTouch 4

This ABLEGRID power supply replaces the original charger for the Maxtor OneTouch 4 model STM303204OTB3E1-RK. It accepts worldwide AC input from 100 to 240 volts at 50 to 60 hertz. The unit delivers DC output through a barrel tip connector. It is a non-OEM accessory built to match the original specifications.

Safety protections and voltage headroom

The adapter includes over-voltage protection and over-heat protection for stable operation. It handles the full AC input range of 100 to 240 volts, so it works on mains supplies across different regions. The DC output is regulated for the drive enclosure. No battery backup or UPS runtime is provided by this adapter alone.

Upgrade from a lost or faulty original charger

This unit serves as a direct replacement when the factory power supply is lost, damaged or no longer powers the drive. The 678% compatibility claim indicates broad fit with the specified Maxtor model. Buyers who need a different connector tip, a higher wattage rating or a battery-backed UPS function will need a different product.

Questions about this item

Will the 100-240 V input let me keep using the adapter if I move between regions with different mains voltages?

Yes, the adapter accepts AC 100-240 V at 50-60 Hz, so it works on mains supplies worldwide without a voltage converter.

How can I verify the adapter is delivering power correctly once I connect it to my Maxtor OneTouch 4?

The drive should spin up and be recognised by the operating system; the adapter includes over-voltage and over-heat protection that will shut it down if a fault occurs.

Does the package include the barrel-tip cable that fits the Maxtor OneTouch 4 STM303204OTB3E1-RK, or must I buy it separately?

The box contains one new AC DC adapter with the barrel tip already attached; no extra cable is required.
