While the solar panel power is the ideal means of supplying needed electric power to MegaVoices, in some conditions (dense rainforest), it may be useful to develop alternative power sources. 

  • It takes 14 hours in direct sunlight to fully charge the player to play 10 hours.
  • The players do not trickle-charge in overcast or shadowy conditions.
  • Player permits an alternative 9V power source to play/recharge.
  • 1.3mm/3.5mm coaxial plug

Potential alterative power sources under development are:

  1. 6 x AA batteries in a pack
    • universally available
    • 25 hour play time
  2. 6 x D batteries in a pack
    • universally available
    • 180 hour play time
  3. Voltage regulator to drop 12V DC (car, motorcycle battery) to 9V DC
