DJI released an USB charger that can be used in conjunction with a compatible DJI intelligent battery to charge your mobile devices in the field.
We all know that the GO App is relatively battery hungry and nothing is worse than seeing the device complain it needs a charge when you are out flying.
The new USB charger is only one of three items required to make it work. You also need a power source ( Intelligent Battery or a Charger ) and a (10 PIN-A or 2 PIN) to DC Power Cable ( if using a battery ).
Here is the relevant info.
