Features:

  • 3 AA/AAA to D Battery Size Adapter
  • Converts AA or AAA Batteries into D Batteries
  • Usage:
    • Open up your device that takes D batteries
    • Place 3 AA Batteries or 3 AAA batteries into this Adapter (AA batteries will last longer than AAA)
    • Place the whole unit into the D battery slot
  • No more need for purchasing D batteries for outdated devices
  • With this adapter the voltage remains the same 1.5V so your devices run on AA's and AAA's just like they would on D batteries. The benefit is that AA and AAA batteries are much more common than outdated D batteries.
