WAWEIS 12V AC Adapter for G-Technology G-Drive G1 0G03902 2TB 4TB

SKU CH-V1AV-63G3A

12 V replacement power supply for G-Technology G-Drive G1 2 TB and 4 TB desktop drives, 100–240 V input with 6.5 ft cord and FCC, CE, RoHS certification

  • World-wide 100-240 VAC input works anywhere
  • 5 ft power cord reaches distant outlets
  • Over-current, over-voltage and short-circuit protection built in
  • FCC, CE and RoHS certified for safety
  • 0 VDC output matches G-Drive G1 0G03902 specification

Purpose and compatibility

This 12V AC adapter replaces the original power supply for G-Technology G-Drive G1 desktop external hard drives, specifically the 2TB model 0G03902 and the 4TB variant. It delivers 12.0V DC output and accepts a world-wide input range of 100-240VAC at 50/60Hz, making it suitable for international use with the correct mains lead. Builders needing a different voltage or connector type should look elsewhere.

Sustained operation

The unit incorporates over-current, over-voltage, short-circuit and total-power protection circuits that engage continuously during extended operation. A smart chip manages overheating protection while anti-interference materials maintain stable output under constant load. These features are designed to support the drive through long backup or archival sessions without triggering safety shutdowns.

Thermals noise and power

The adapter runs on standard mains frequencies of 50 or 60Hz and draws power only as demanded by the connected drive. Its 6.5 ft power cord allows flexible placement away from the drive enclosure to aid airflow. No active cooling fan is present, so operation remains silent; the housing relies on passive dissipation certified to FCC, CE and RoHS standards.

Questions about this item

How much heat and noise does the 12 V adapter produce when powering a G-Drive G1 continuously?

The adapter has no fan and relies on passive cooling; it runs silently and stays cool under normal 12 VDC load.

What must I already own to use this adapter with my G-Drive G1?

You need the G-Technology G-Drive G1 desktop drive (models 0G03902, GDREU3G1PB20001BDB 2 TB or GDREU3G1PB40001BDB 4 TB) and a standard IEC C7 mains lead.

Will the 6.5 ft cord and 12 V output work with an older G-Drive that uses the same barrel connector?

Yes — the 12.0 VDC output and centre-positive barrel match the original supply, so legacy G1 units power up without modification.
