Sooo I went down the Amazon-hub rabbit hole too… honestly I’d just grab DJI 100W USB-C Power Adapter and keep ur 65W GaN as travel backup.
- 65W PD works fine (slower), 100W PD is the sweet spot
- Skip no-name hubs; battery heat/handshake is a gamble
cheers

i've flown for years and tbh i stopped chasing random hubs—my current setup is a simple sequential USB-C hub + a legit 65W PD GaN, and i just dont charge packs hot; heat’s what kills em, not speed.

Hey, i feel u — swapping packs is annoying. Here’s what I’d do:

- **Option A (safest/value):** stick with DJI accessories in general. Their hubs/charging stuff just “talks” to the batteries right, and I’m satisfied w/ temps + battery health.
- **Option B (cheaper):** a reputable 3rd-party hub is probably fine, but only if it’s USB-C PD and doesn’t get hot.
- **Charger:** ur 65W GaN PD is perfect; use a decent USB-C cable and don’t charge in a sealed bag (heat is the real killer).

Story time: I did the same manual swap thing at first… got old fast lol. What I learned is the “hub” matters way less than the USB-C PD source and heat. With my current setup (a generic multi-bay hub + 65W GaN), it charges sequentially but it’ll downshift if the brick/cable isn’t truly PD (some C-to-C cables are sketchy). I started resting the hub on open air, not in my bag—temps dropped a lot. honestly that was the biggest battery-health win, you know?

Ok so i feel u… swapping packs gets old fast lol. For your setup, I’d stick with the official DJI Mini 4 Pro Two-Way Charging Hub — it’s been *super* reliable for me and does the “charge in sequence” thing without drama. Pair it with your 65W USB-C PD GaN brick (or even 30–45W works, just slower). Third-party hubs are tempting ($20-30ish), but imo not worth the heat/battery-health gamble. cheers!

Saw this thread earlier and wanted to offer a different perspective. @Reply #5 - good point regarding the wattage requirements, but I've always found that the official accessories carry a significant price premium that isnt always justified. In my experience, building a more modular DIY charging kit is much more effective for travel. I've tried many different setups over the years and I'd suggest looking at any high-output multi-port charger from Ugreen. You really cant go wrong with their PD-compliant hardware. Taking a DIY approach allows for a much more streamlined bag. Instead of carrying a hub that only works for one device, I prefer using a universal multi-port power station that can manage the drone batteries alongside a laptop and phone. As long as the power delivery specs match up and you use quality cables, the safety concerns are largely mitigated. I've found this method much more cost-effective and practical for field work than sticking strictly to the official ecosystem.
