Featured power supply categories

AC-DC Adapters

  • 5V adapters for microcontrollers & LEDs
  • 12V adapters for motors & strips
  • High-current adapters for demanding loads

Bench & DC Sources

Tip: Always choose a supply with at least 20–30% current headroom to avoid undervoltage, especially for motors and Raspberry Pi systems.

Power supply chooser (quick guide)

Need Good first choice Notes
Power Arduino or ESP32 5V 1A–2A adapter Stable for sensors, modules & small motors.
Power Raspberry Pi 5V 3A USB-C/micro-USB Prevents undervoltage; use thick cables.
Robots & motors 12V adapter or battery pack Pair with a converter for 5V logic rails.
Portable IoT nodes Li-ion 18650 or LiPo Combine with boost/buck modules as needed.
Lab & testing Bench power supply Adjustable voltage/current for safe prototyping.

Check voltage, current, polarity & connector type before powering devices.

FAQ

What power supply do I need for microcontrollers?

Most boards run on 5V via USB or 7–12V via VIN. Check each board’s requirements before connecting.

Can I use phone chargers for electronics?

Yes, as long as they're stable 5V. For high-current devices like Raspberry Pi, use rated adapters.

Do bench supplies offer better protection?

Yes—bench supplies have adjustable current limits to prevent accidental shorts or overloads.

Do you ship nationwide?

Yes—fast shipping anywhere in the Philippines. Same-day processing for in-stock items.
