The branch loads usb sticks with videos and content and sends it to the congregation, who then load it to the jw box, which the publishers connect and download into their devices.
It works as a normal device and can be charged through usb, adapter or power bank.
The best part, they want donations of $75 for it! So they don't provide any physical food to people in Africa but they can send them "Spiritual Food" for $75.
Turns out, you can buy the same exact thing on Amazon for $45!!! All they did was slap a JW Logo onto of it and cover over the name of the product with a white sticky tape.
let's say they bought these in bulk for 20 dollars. If they sell 1million of these at a 50.00 dollar profit. The org just made 50 million !
