Teardown of the Little Wildman Multi-Function Flashlight
In daily life and outdoor activities, a flashlight is almost an indispensable piece of equipment. Whether for camping, hiking, home emergencies, or nighttime adventures, a fully functional flashlight can greatly enhance the user experience. In this issue, the irayenergy editor will tear down a product known as the “Little Wildman Multi-Function Flashlight” to see what its internal design is really like.

1、Function Design Overview
From its appearance and features, the selling points of this flashlight are quite outstanding:
Multiple lighting modes: Can be used as a desk lamp, magnetic light, portable lamp, handheld light, or hanging light.
Wide application scenarios: Camping, hiking, home use, exploration, emergencies — almost fully covered.
Modern charging method: Equipped with a Type-C port for high compatibility and convenient charging.
Switchable light colors: Supports both white and warm light, meeting different illumination needs.
Lightweight and portable: Weighing only 120g, making it easy to carry outdoors.
Simple operation modes: Short press to turn on flashlight mode, long press to enter strobe mode, press again to switch to SOS mode.
In addition, the tail integrates a Type-C charging port, magnetic base, and a hidden hook, making it quite practical. However, in desk lamp mode, it requires an additional plastic lampshade. Since the lampshade is a separate detachable design, it may be inconvenient in actual use — easy to misplace or lose. If it were integrated into the body, it would be much better.

2、Teardown Process
This flashlight adopts a cylindrical structure, secured by threaded rotation. Step by step disassembly reveals the following:
2.1 Head Structure
Equipped with a high-power long-range LED chip, with a claimed brightness of up to 1200 lumens.
The LED is mounted on an aluminum substrate coated with white oil to enhance reflection — a common method in lighting products for heat dissipation and light efficiency optimization.

2.2 Circuit Board
The main control circuit includes:
Yuxin YX4056C: A common lithium battery charging management chip using CC/CV charging mode. It has a high level of integration, requires few external components, and is stable and reliable.
Unknown MCU: Marking has been polished off, but it is assumed to handle button logic control and LED driving.
Four SI2301 MOSFETs: Responsible for power control and switching.
The back of the circuit board features a large exposed copper area with soldering, which improves heat dissipation — particularly important for high-power lighting products.

2.3 Battery
Built-in 18650 lithium-ion battery, model HYLN-IMR18650-1800mAh, supplied by irayenergy.
The battery uses a steel shell package, providing good safety and energy density.

2.4 LED Module
The front aluminum substrate integrates two types of LEDs: light yellow for white light, dark yellow for warm light.
Switching between light sources is achieved through circuit control.
At this point, the entire flashlight has been fully disassembled.

3、Product Improvement Suggestions
Despite its practicality, some shortcomings in user experience are worth mentioning:
Lack of brightness adjustment: At close range, reflections are harsh and uncomfortable. Multi-level brightness adjustment would greatly improve comfort and extend battery life.
Inconvenient detachable lampshade: Searching for the separate lampshade during use is unrealistic. A foldable or integrated design would be better.
Poor battery endurance: Although rated at 1800mAh, the battery drains quickly under high brightness. Using higher energy density cells (2600mAh or 3000mAh) would yield better results.
Limited operation logic: While long-press strobe and SOS modes are useful, users who need different brightness levels may find the operation insufficiently flexible.
4、Conclusion
The Little Wildman Multi-Function Flashlight indeed stands out in functional design: multiple lighting modes, Type-C charging, white/warm light switching, and lightweight portability. However, teardown reveals that improvements are still needed in circuit design, battery utilization, and brightness adjustment.
For ordinary users, it is sufficient for daily emergency lighting and outdoor use. But for enthusiasts or people who work outdoors for extended periods, the capacity may feel inadequate, and the functions somewhat limited.
An ideal flashlight might include the following features:
Multi-level brightness adjustment to balance close-range and long-range needs.
Battery capacity above 2600mAh, with fast charging support.
Integrated lampshade design to prevent loss.
More user-friendly mode switching, such as short press for brightness levels and long press for power-off.
Better heat dissipation and power efficiency optimization.
