This charger and additional batteries are a must have. Why this isn't part of the main camera kit is beyond logic. As for the chargers, it's pretty quick to charge two dead Insta360 Pro batteries. Since each battery lasts 75 minutes, you'll need at least three batteries (four is better) to keep one fully functional at all times. I wish Insta360 would offer a 9V/2A car adapter to start and charge the batteries while running. Street. For those of us who know how to handle solder/crimp wire, one of the options is to get a DC power cord and plug it into https://www.amazon.com/Magnolian-Efficiency-Converter-Supply-Waterproof/ . dp/B00A71E52G/ or https://www.amazon.com/Regulator-DROK-Adjustable-Transformer-Stabilizer/dp/B07LC4LNTD/ Now that I think about it, there might be something handy that works. However, you still have to choose between using a USB power adapter or 12V power from a car outlet.
