    After a long overnight charge this charger charged my phone, oculus quest (partly) and megaboom 3 multiple times for over 4 days in a beach getaway. Only gripe would be it’s long charge time and weight. Regardless I s a great product for the price.

    Took a few hours to initially charge through my lap top that was plugged in. Worked quick to charge my old iPod. Real test will be when I go hunting. Want to be able to charge phone, Fit Bit, etc. when I have limited access to electricity.
