I just bought the air 3s upgrading from my deceased air 2s, I found out however I need to buy a power brick, I will probably stick to the 3 batteris right now and I usually shoot up to 6 or 8 hours events which requires continuous battery use and flights with no downtime, I can't figure out however which 100w powerbrick will work with the dji hub or even if I upgrade to the:
LKTOP 200W Air 3/Air 3S Battery Fast Charger Hub for DJI/Specta Air 3 Series Drone USB-C Power Adapter, with Gather Average Electricity/Fast Charging/Storage/LED/Alarm Mode, LED Display Screen
This one needs TWO 100w for max performance...
My second use case is charging the drone while in the car for work related, can I use a 200w inverter to charge my batteries while in the car using any of the above two chargers or inverter is not meant for that ??
Finally am considering this but it charges two batteries only simultaneously within 75minutes...
Is it any good ?
