I picked up a 4 battery charger. The power input connector looks like the connector for the Inspire 1 controller charger and matches the specs on the charger, but it does't seem to work. The single battery charger that comes with the Osmo handle is AC input so I know it won't work. Anyone know if the 4 battery charger will work with the I1 controller charger cable? Trying to figure out if I got a dud or there's yet another DJI charger I need. Note that I have the accessory handle that works with the X5 camera, not the stand-alone Osmo. Maybe the stand-alone comes with a different charger?
