To use a DJI two-way charging hub, click your batteries into the slots, then connect a USB-C Power Delivery charger to the hub. The hub charges the battery with the most power first, then the next, so you get a full battery as soon as possible. To use it as a power bank, unplug the charger, leave batteries in, and plug your phone or controller into the hub's USB port. Some hubs can also move leftover charge into one battery.
Charging batteries
- Insert the batteries until they click. The LEDs show each battery's level for a few seconds.
- Connect the charger to the hub's USB-C input. Use a USB PD charger, ideally DJI's: the 30W charger suits the Mini hub, the 65W charger suits the Avata 2 and Neo hubs.
- Leave it. The hub charges the highest battery first, then the others in sequence.
- Remove each battery when its LEDs turn solid green.
If charging doesn't start by itself, press the hub's function button. Batteries that are too hot or cold wait until they're in range; DJI's Mini batteries charge between 5° and 40° C (41° and 104° F).
Charging times
| Hub | DJI's figure |
|---|---|
| Mini 4 Pro / Mini 3 | About 58 min per Mini 4 Pro battery with the 30W charger |
| Avata 2 | About 45 min per battery with the 65W charger |
| Neo | Three batteries in about 60 min with the 65W charger |
| Air 3 series | About 60 min per battery with the 100W adapter |
The Neo hub charges batteries at the same time; DJI says a charger under 45 W only handles two at once.
Using it as a power bank
- Disconnect the charger. Leave at least one battery in the hub.
- Plug your device into the hub's USB port with a cable.
- If it doesn't start, press the function button.
The hub drains the lowest battery first. The Mini 3 Pro hub's USB output is 5 V, 2 A, which is fine for a phone or an RC-N3 but slow for a tablet. The Avata 2 hub stops powering devices once a battery drops below 7%. More in using a DJI battery as a power bank.
Power accumulation
Some hubs, including the Avata 2 and Air 3 series hubs, can move leftover charge from several part-used batteries into the one with the most charge. On the Avata 2 hub:
- Insert two or more batteries, with no charger connected.
- Press and hold the function button until the status LED turns green.
- The LED pulses green while power moves into the fullest battery.
- Press and hold again until the LED turns yellow to stop.
It stops by itself when the receiving battery is full, the giving battery drops below 5%, or you connect a charger or device. This is handy at the end of a day of flying: three half batteries become one you can fly.
The Mini 3 Pro hub's guide uses a two-second press-and-hold to switch charging priority instead, so check your own hub's guide.
LED quick guide (Avata 2 hub)
| Status LED | Meaning |
|---|---|
| Solid yellow | Idle |
| Pulsing green | Charging or accumulating |
| Solid green | Batteries full, or powering a device |
| Blinking yellow | Battery too hot or cold; it will resume |
| Solid red | Charger or battery error; reinsert and reconnect |
Storage tips
DJI recommends storing batteries in the hub. Don't leave them flat for long: charge low batteries promptly, and keep them at storage level if you won't fly for a while. Read drone battery care and our battery charging guide.
The Mini 4 Pro / Mini 3 Two-Way Charging Hub is from $54.
