Tomzon D25 – Cheap 4K Drone with 2 Batteries
The Tomzon D25 is an affordable drone with 4K camera and is best suited for beginners who want to gain their first experience with camera drones. The foldable drone allows viewing the live image of the camera (FPV flight) and comes with two batteries for up to 24 minutes of flight time.
Design and weight
On the outside, the Tomzon D25 looks completely gray. The sporty design of the small quadcopter is strongly reminiscent of the popular DJI Mavic Mini, which, however, is in a completely different price range.
With its arms unfolded, the quadcopter measures 23 x 23 x 5.6 cm; when folded, the dimensions are reduced to 12.5 x 8.9 x 5.5 cm. The drone is made of sturdy yet lightweight ABS plastic, which gives the drone the necessary robustness.
The four rotors of the Tomzon D25 are driven by powerful brushless motors, which are more powerful as well as quieter than cheaper brushed motors.
For the protection of the drone in case of collisions as well as for the safety of bystanders, the Tomzon D25 has four propeller guards that can be easily mounted on the motor mounts. Therefore, the quadcopter is also suitable as a drone for children.
Two bright LEDs on the front and two red glowing LEDs on the back provide the necessary visibility of the drone in the sky.
The remote control of the Tomzon D25 is ergonomically designed and offers a retractable mount for smartphones on the top. For transport, the controller including the drone can be stored in the practical carrying bag.
Equipment and flight characteristics
The Tomzon D25 has a number of useful features that should make it easier for you to use the drone. For example, takeoff and landing work conveniently at the push of a button. As soon as the drone has lifted itself into the air, it independently maintains the current altitude thanks to Altitude Hold – so permanently pressing the thrust controller is not necessary.
Although the Tomzon D25 does not have a GPS module, it does have an optical flow sensor on the underside of the drone. The sensor is a small camera that continuously films the ground below the drone and thus provides a position fix. Especially when flying indoors – where no GPS signal is available anyway – an optical flow sensor is very helpful and ensures the necessary stability of the drone.
Due to the lack of a GPS module, there is also no Return-to-Home mode and the drone must therefore be landed manually on the landing site or the ground.
Depending on your skill level, two different speeds are available for controlling the drone. Beginners in particular will also be happy about the so-called headless mode. In this mode, a simplified control of the drone is available to you as a pilot.
In headless mode, the current orientation of the drone in the air does not matter when you execute control commands to the left, right, up or down. The drone will always fly in the desired direction, regardless of whether the front or tail is currently facing you. The otherwise necessary rethinking based on the orientation of the drone is therefore not necessary in headless mode.
However, we recommend that you do not fly in headless mode for too long and also learn the normal controls of the drone, as not all drones have headless mode.
A nice gimmick of the Tomzon D25 is the built-in gesture control. You can easily trigger photos and videos via gesture command. To take a photo, simply form your fingers into a “Victory sign”. To start a video, hold your outstretched hand towards the drone.
Another fun feature is the ability to perform 3D flips at the touch of a button. The Tomzon D25 is capable of flips in different directions, which can be easily performed at the push of a button.
Flight time and range
The flight time of the Tomzon D25 is up to 12 minutes – per battery. Since the small drone comes with two 3.7 V, 1100 mAh batteries from the factory, you can enjoy up to 24 minutes of flight time before the batteries need to be recharged via the included USB charging cable. One charging process takes about 60 to 120 minutes, depending on the power adapter used.
Since no power adapter is included, simply use the one on your smartphone or charge the batteries via USB on a laptop or PC.
The control range is about 110 yards (100 meters). Unfortunately, the FPV transmission does not work quite that far. Already after about 33 yards (30 meters), the first jerks and interruptions in the image transmission occur. We therefore recommend that you always keep an eye on the drone to avoid the risk of a crash or collision.
The camera of the Tomzon D25
The 4K camera of the Tomzon D25 records photos and videos in 4096 x 2160p. The quality of the recordings is quite decent for an inexpensive camera drone, even though the results cannot keep up with more expensive drones with cameras for a long time.
The camera can be tilted vertically by up to 90° before the flight, so that different shooting perspectives can be set.
Since the Tomzon D25 does not have a slot for memory cards, photos and videos are stored directly on your own smartphone.
To view the drone’s live FPV image, you first need to download the Tomzon-G app. The app is available for free download in the respective app store for both iOS and Android devices. For an uncomplicated installation, QR codes can also be found in the operating instructions, which lead directly to the app download.

Conclusion
The Tomzon D25 is an affordable quadcopter that is best suited for beginners who want to gain their first experience with a camera drone. The drone has a 4K camera that records photos and videos in 4096 x 2160. The quality of the recordings is okay, but naturally cannot keep up with the results of more expensive drones by far.
We very much like the fact that there are two batteries for 2 x approx. 12 minutes of flight time. The range of 110 yards (100 meters) is not outstanding, but is still sufficient for first flight experiences.
Overall, the Tomzon D25 is a very good entry-level drone at a fair price.
