Audio Bibles that come in a preferred language and you can also use SD cards. That would allow you to use Eliyah's teachings. http://www.renewoutreach.com/papyrus-solar-powered-audio-player/

Another awesome tool is this: http://www.renewoutreach.com/lightstream

Allowing you to be a wifi hotspot anywhere for teachings and bible readings. It can automatically download to people's devices. This is working out great in hostile countries spreading the Good News covertly, digitally.

Shalom
