I'm an electrical engineer, so I always evaluate products like this relative to choices I would have made given my personal priorities if I were designing it. It's rare that a product makes a bunch of decisions I wouldn't have that turn out to be better for me than I'd have done. This is such a product.
I could go on for a while here about the technical merits, but I'll keep it short:
* Sequential charging, which is ABSOLUTELY better than all-at-once. This charger is designed to pull 18 watts from the wall from a strong enough PD or QC3 charger. It will push all of those 18 watts into the most-full battery, i.e. the one you will be flying with next. As soon as there's power available for subsequent batteries, it'll charge those in turn. I think people see "sequential" and think "parallel" would be faster, but it's not the case. The batteries are 17.3 Wh, which means 100% of the wall power is consumed charging one of them at full speed. Charging two half as fast would only be a benefit if you need to fly two drones at once, and even then, you'd get there just as fast charging one battery then the other
* Switchable battery vs external priority: By default, batteries get charged first, THEN power gets passed to an external device (presumably your phone or controller). You can switch this if you so choose, like if you're in a hotel at night and want your phone powered first, then the batteries once you're asleep (hold the power button for 2s). GREAT attention to detail.
* Disables battery self-discharge: The intelligent flight batteries are super customer-friendly in that after a day of non-use, they self-discharge slowly to something like 70%, which is less stressful on the battery over time. Perhaps you're used to cheap third party action cam batteries: you regularly charge them all up for vacation then use only one. The first time you used a battery, it gave you full discharge life. But after a year or two, even though you've only used it twice, it barely holds a charge. These batteries won't do that.
On the other hand, if you NEED the charge, like you're charging up for vacation and need them ready for service for the rest of the week, keep them parked in this charger. It'll stop their self-preservation discharge cycle until you pull them out.
I bought the genuine item because the more I learn about battery management, the more I recognize that cheap third party suppliers ACTUALLY make bad designs that kill batteries much too early, and I suggest you stick with the OEM for the same reason. That said, it looks like some of the imitators have cloned these features as well.
