DJI 3-Battery Two-Way QC and USB PD Fast Charging Hub with Intelligent LED

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.

great product. now i can easily charge all the batteries at once without having to swap them out of the drone itself. mind you it charges them in sequence and not all at once, which makes sense i guess. the batteries can be a little tedious to slide in and out if you don't press the little release just right but that seems minor. all in all it does what its supposed to do. i've never actually used it to charge my phone , which is one of the features but perhaps i'll write another review or update when i do.

Solid product, charges in sequence not all three at once.

100%

This charging hub is a game changer. I have 3 batteries for my mini 2 but didn't have the hub so I had to charge the batteries one by one in my drone. Now that I have this hub, I can have my batteries charging while I'm flying. I also like that it uses the USBC to charge it which means I can use my portable power bank to charge my batteries. Be aware that this hub can act as a power bank to charge your phone or controller however it uses your mini 2 batteries to do so. The hub does not have its own battery pack or anything like that. If you want to charge your batteries in the field you need to bring a portable power bank or find an outlet somewhere. The battery hub also does not come with any cables so you will need to provide your own. Also, do not store your batteries in the hub! The DJI Mini 2 uses lipo batteries, which need to be stored with around 3.8 V per cell. Any higher or lower could result in damage to the battery. DJI has made their batteries super smart and allows them to self discharge to the required 3.8 V per cell, however if you leave them in your hub or drone the battery can't discharge and thus could result in damaged batteries. Another thing to be aware of is that the battery hub does not charge all batteries at once. It charges them one at a time, starting with the battery with the highest voltage. Overall, I think having this hub is essential for DJI mini 2/ mini SE if you have more than one battery. I'm not sure it's really worth $40 though.

Llegó en buen estado y es muy útil tener varias baterias adicionales.

Works great

Authentic 3 battery charger for the DJI mini 2 / 2 SE / 4K. Was happy to find it as I decided to piece together a fly more accessory list after buying the drone alone.

Charges 3 batteries in sequence. Can be used to charge other devices, like a cell phone. A little expensive given what it is, but has good build quality and performs as advertised.

Great for charging and storing batteries

Ein absolutes MUSS für jeden der mehr als einen Akku hat .. ansonsten muss jeder Akku einzeln in die Drohne gesteckt werden und dann an die Dose .. so drei gleichzeitig und die dritte kann im Koffer bleiben, wirklich nützlich :))

Funciona perfectamente.

Le seul défaut est qui ne recharge les batteries lentement
