My son is going to College next week and has some very long days: 8am - 9pm. We're concerned that his batteries might not make it through because a good chunk of that time will be receiving FM signal (4 hours on one of the days). We found the portable charger but have seen very few reviews. Has anyone used the Chargergo Infinio or heard about it? My understanding is that it's the same as the wall charger but with a rechargeable battery pack. It's a lot of money so checking.
Thanks!
Thanks!
