I just purchased a Osmo Mobile, read the instructions, then procceded to charge it all day without anything happening.
- Removed the clear plastic cover on the battery, and inserted the battery into the osmo
- Plugged the headphone jack side of the supplied charging cable into the osmo
- Plugged the USB side of the supplied charging cable into my macbook air USB port
- Left it plugged in all day (6+ hours)
So far no lights blink on the osmo indicating that it is charging and it wont power on.
