I don't understand why you would not just spend $50 a a rechargeable power unit that holds enough power to run the Mojo for a few days. I've seen people say this a few times in this thread and it just boggles my mind that people are so unaware of inexpensive powerpacks.
You mean charge the Mojo while using the Mojo ? So in MY CASE when I go to three different schools to coach which takes multiple trains, buses and a taxi which usually takes 3 hours a day of traveling. I should take two phones (one to use as a phone the other to use with the mojo) the Mojo and a charger on my daily travel in Hong Kong? Sorry this boggles your mind. I read its BEST not to use the Mojo while CHARGING the Mojo. In Hong Kong its 98% humidity and reaching close to 40°.
I have mine plugged into a charger 95% of the time I am using it. But I don't live in hell. Enjoy your weird ways. (and your deep pockets)
