Unfortunately the Spark Portable Charger only charges one battery at a time.  So we are forced to wait anywhere from 1.5 hrs to 2.5 hrs for 3 batteries to charge (depends on if plugged in or not).

I got to thinking what if I don’t put the Spark in the carrier, but instead ran a USB cable from the charger USB port (the one used to charge the remote) to the Spark.  Would I then be charging 2 batteries at the same time?  Anybody tried this?

So like everyone recommended, I ordered the Official DJI Portable pack (with 2 batteries). The batteries are charged sequentially, that’s why it takes over 1.5 hours for all 3, but one battery takes about 30-40mins which means the time to 192.168.100.1 192.168.1.1 fly (again) is much less.
