# Parameters

### 1.What’s the latency of the DJI Digital FPV System?

End-to-end latency is the total time it takes for information to be transferred from the camera input to the display screen. The lowest latency of the DJI Digital FPV System is within 28 ms and provides 720p/120fps image quality. This is achieved most often in wide open areas with no electromagnetic interference.

### 2.What is the resolution of the DJI FPV Goggles’ screens?

1080×720 with an aspect ratio of 4:3, and 1440×810 with an aspect ratio of 16:9.

### 3.What is the supply voltage and power consumption of the DJI FPV Goggles?

The DJI FPV Goggles use an external battery with a voltage range of 7.4-17.6 V. Customers are recommended to use 4S batteries. The total power consumption is about 7 W. The battery life of one 4S 1600mah battery is 3.5 hours when used continuously.

### 4.What video recording format do the DJI FPV Goggles support?

MP4 videos at 720p/60fps.

### 5.What video files can the DJI FPV Goggles play?

MP4, MOV, and MKV (H.264) videos.

### 6.What types of storage cards do the DJI FPV Goggles and DJI FPV Air Unit support?

The DJI FPV Goggles supports microSD cards with capacities of up to 128GB.

{% hint style="danger" %}
Use at least C10 class Micro-SD card
{% endhint %}

### 7.What video recording format does the DJI FPV Air Unit support?

MP4 videos at 1080p/60fps and 720p/120fps.

### 8.What is the maximum transmit power of the DJI FPV Air Unit under each wireless certification standard?

FCC/SRRC: 700 mw \
CE: 25 mw \
MIC: 350 mw\
**With power hack it can goto 1200mw**

1. Prepare a Micro-SD card, and then create a file in the root directory of the card and name it "naco\_pwr.twt".
2. Enter "pwr\_2" in the file and save.
3. Insert the Micro-SD card into the Goggles, power on and wait for boot.
4. Finally you can see 1200mw in the menu.

### 9.What is the supply voltage and power consumption of the DJI FPV Air Unit?

The DJI FPV Air Unit uses an external battery with a voltage range of **7.4-17.6 V**. Customers are recommended to use 4S batteries. The power consumption of the video transmission system ranges from 4-9 W in normal temperatures.

### 10.What ports do the DJI FPV Remote Controller have?

The DJI FPV Remote Controller has a USB Type-C port and a 3.5mm audio interface. In the last firmware to use simulators, you can use Type-C cable to connect between Controller and PC. It can support like DRL/DCL/Velocidrone simulators.

### 11.What is the control latency of the DJI FPV Remote Controller?

The control latency is the total time it takes a command to be transferred from the remote controller to the flight control. The latency of the DJI FPV Remote Controller can go as low as 7 ms if you are using the Sbus Baud Fast protocol. (Flight controllers must be updated with the latest firmware for users to enjoy 7ms low latency).

### 12.What’s the battery life of DJI FPV Remote Controller?

A fully charged battery can last up to 7.5 hours when operating continuously.
