What's the big deal?? As DJI does not provide a RC specific power supply (power blocks are NOT chargers) they expect you to use any industry standard 5vDC 2A or less power supply, ie, most any cell phone or mobile device power supply. So many people confuse a power supply with a charger, any modern device has the charge controller built in. I have been charging my RC with both a power bank, and a Apple 2A iPad power supply from day one as the USB outlets in the Mavic power supply are only 1A each, slow charge.
