I ordered 2 Mega 510 and I have a USB charger, the charger can be hooked up to a USB port or I can hook up an extrnal power supply. This might be a dumd question but does the switch have to be depressed for the 510 to be charging. It does make sense but want to ask.
 
I left it on charging all night but the light never turned to blue when it means it's charged.
