DJI launched a few new accessories for the DJI Spark (still priced at $399!), our favorite mini-drone. Last week they introduced the Spark Portable Power Charging Station for USD $89, which is a battery-powered charger for up to three Spark batteries. The charger itself can be fully charged in 1 hour and 35 minutes and can in turn charge up to three Spark batteries in 2.5 hours with its own 5000 mAh battery.
This week DJI introduces the Spark Portable Power Pack for USD $139 but the DJI website is unclear about what you will be getting when you buy this item.
Update: DJI updated their website on 11/30. The Spark Portable Power Pack does include two batteries.
