MT3608 DC-DC Adjustable Boost Module 2A Step Up Micro USB
MT3608 DC-DC Adjustable Boost Step-Up Module with Micro USB — 2V–24V Input to 28V Output
The MT3608 DC-DC Adjustable Boost Module is one of the most compact adjustable step-up voltage regulators available. Whether you're powering a DIY electronics project, a custom embedded system, or need a reliable voltage conversion solution, this ultra-small boost plate delivers wide-range voltage conversion with high efficiency in a tiny 30 × 17 × 14 mm footprint.
With its built-in Micro USB input port, you can power the module directly from any standard USB charger or power bank — instantly stepping up 5V USB power to 9V, 12V, 15V, 18V, 24V, or any voltage within the supported range. Perfect for hobbyists, electronics engineers, and makers.

How to Use
- Connect your input power source (2V–24V) via the Micro USB port or the input solder pads.
- Use a multimeter to monitor the output voltage.
- Rotate the onboard potentiometer to adjust the output to your desired voltage.
- Tip: If the output voltage cannot be adjusted and equals the input voltage, turn the potentiometer counterclockwise 20+ turns first, then fine-tune. Facing the potentiometer, turning counterclockwise increases (boosts) the output voltage.
⚠️ Important Notes
- Do not exceed the maximum input voltage of 24V.
- Do not exceed the peak output current of 2A.
- This is a step-up (boost) module only — the output voltage must always be set higher than the input voltage.
- For sustained loads, keep output current at or below 1A to ensure stable operation and longevity.

Frequently Asked Questions
Q: Can the MT3608 boost module step voltage both up and down?
A: No — the MT3608 DC-DC module is a step-up (boost) converter only. The output voltage must always be set higher than the input voltage. It cannot be used as a buck (step-down) converter. If you need both step-up and step-down capability, you would need a separate buck-boost module.
Q: Can I power the MT3608 boost module directly from a USB power bank or phone charger?
A: Yes! That is one of the most popular use cases for this module. Simply connect a standard USB charger or power bank to the onboard Micro USB port (which provides 5V input), then adjust the potentiometer to set your desired output voltage — such as 9V, 12V, 15V, 18V, or up to 26V — making it extremely convenient for field use and portable DIY projects.
Q: What is the recommended maximum continuous output current for the MT3608 module?
A: While the MT3608 boost module can deliver up to 2A peak output current, it is recommended to operate at or below 1A for continuous use. Exceeding this under sustained loads may cause the module to overheat or reduce its operational lifespan. For higher current demands, consider adding a heatsink or using a higher-rated boost module.
