In short, unusable state. I think using the plug-my cell phone charger, but upon why I buy more USB cable to connect this jack to the charger; knowing that in addition, this charger requires a certain voltage and amperage that my laptop charger jack does not offer! Slow charges in perspective, and again ... if it works!
Even regardless of price, I think it is ridiculous to offer customers chargers .... without taking that goes with it to ensure its food. Ridiculous. While this, in itself, is ripe for the use I make account. Yes ... I intend to do, as it should not be pressed next delivery. I received the charger but not the batteries that are supposed to come with ... not to mention the quadricopter itself is somewhere in transit!
