Can this be charged using a USB wall charger?
I have wondered why these devices specify "charge using your computer" but none say it's ok to plug into a USB wall charger. I used the wall charger with my Fitbit and the thing never charged or worked right. I don't know if the device was defective or if it was because I used the USB wall charger. At any rate, I like the Vivosmart and want to make sure using the USB wall charger will not negatively affect the functionality of the device. Thank you.
