All-in-One Flashlight Driver Module with Type-C Charging — Perfect for 18650 & 10W LED DIY Projects

Take your DIY flashlight builds to the next level with this compact, feature-packed All-in-One Flashlight Driver Module. Combining a tactile switch, driver circuit, and Type-C charging port into a single lightweight PCB, this module eliminates the need to source and wire multiple components separately — making it the ideal solution for hobbyists, makers, and electronics enthusiasts.

Made in Mainland China.

Key Features

All-in-One Design: Integrates a tactile flick switch, LED driver circuit, and USB Type-C charging function on one compact board — streamlining your DIY flashlight assembly.
Modern Type-C Charging Port: Enjoy faster, more reliable charging compared to legacy USB standards. The 1A charging current quickly replenishes your 3.7V–4.2V lithium-ion battery.
Optimized for 10W High-Power LEDs: The onboard driver is engineered specifically to power 10W LED beads, delivering consistent, high-brightness single-gear output.
Wide Input Voltage Compatibility: Accepts 3.7V–4.2V input, making it perfectly matched for a single 18650 or similar rechargeable Li-ion cell.
Safe & Reliable Charging Circuit: The integrated 1A charging IC protects your battery with stable, regulated power delivery.
Ultra-Lightweight & Compact: Weighs approximately 1.25 grams — barely noticeable in any handheld flashlight build.
Multi-Pack Options: Available in 1, 3, 5, or 10-piece quantities — great for bulk DIY projects, prototyping, or keeping spares on hand.

Frequently Asked Questions

Q: What battery type is compatible with this flashlight driver module?

A: This module is designed to work with 3.7V–4.2V rechargeable lithium-ion batteries, most commonly a single 18650 Li-ion cell. It is not compatible with non-rechargeable or higher-voltage battery configurations.

Q: Does this driver module support multiple brightness levels?

A: No — the driver operates at a single brightness level (one gear), providing steady, full-power output to your 10W LED bead. There is no dimming or strobe function included.

Q: Can I use any Type-C cable to charge the battery through this module?

A: Yes. Any standard USB Type-C cable will work for charging. The onboard charging IC limits current to 1A, so the module charges safely regardless of the power adapter used (as long as it delivers at least 5V).

Q: Is this module suitable for beginners in electronics DIY?

A: Absolutely. The all-in-one design means fewer individual components to source and solder. If you are comfortable with basic soldering and understand lithium-ion battery safety, this module is a great starting point for building your own high-power LED flashlight.
