S3 mobile use

Otso Ylönen

Does anyone have experience of using an S3 outside of the power grid? I am wondering how I could use one at my cottage that relies on battery power. So, far I have powered everything with 12V car batteries. This has meant that I cannot charge my laptop while listening (to mediumwaves) because of the interference from step-up converters. Thew S2 has obviously not caused any problems because it gets its power from the laptop.
BR, Otso
