GuanTing 12V 3A Power Supply AC Adapter Charger

Bottom line: The GuanTing 12V 3A Power Supply AC Adapter Charger ($9.59 on Amazon as of 2026-10-07): 11 interchangeable DC tips: 6.3x3.0mm down to 2.5x0.7mm plus wiring connector; main trade-off: fixed inner-positive polarity, so center-negative gear needs a different supply.

Pros & Cons

Pros

  • ✓ 11 interchangeable DC tips: 6.3x3.0mm down to 2.5x0.7mm plus wiring connector
  • ✓ 36W max output covers 12V loads at 3A, 2.5A, 2A, 1.5A and 1A

  • ✓ CE/FCC/DoE VI certified with over-voltage, short-circuit and surge protection

Cons

  • ✗ Fixed inner-positive polarity, so center-negative gear needs a different supply
  • ✗ GuanTing recommends staying under 80% of 36W for long runs, cutting usable headroom
  • ✗ You must measure your barrel jack and current draw before ordering or it may not fit
  • ✗ Cord length is not listed, so placement behind a desk or rack is a gamble
