  • Boosts .9V to 5V input to stable 5V output
  • Delivers up to 600mA for small USB devices
  • High-efficiency PFM control extends battery runtime
  • Onboard USB-A port enables direct charging
  • Pack of 10 modules suits DIY and assembly

Ten-piece boost module pack

This pack contains ten identical DC-DC boost converter modules designed for hobbyists and engineers who need to step low cell voltages up to a stable five volt rail for tiny USB-powered gadgets.

Sustained-load behaviour

Each board uses a PFM control scheme that keeps no-load current draw low and maintains high conversion efficiency, allowing the 600mA rated output to run continuously without thermal throttling in compact enclosures.

Pre-order checklist

Verify your source cell can deliver at least .9V under load and that the downstream device never exceeds 600mA; the onboard USB-A port is fixed at five volts so confirm the target equipment accepts that exact voltage.

Questions about this item

How much power does the module draw when it is running all day with no load attached?

The PFM control scheme keeps no-load power consumption low to extend battery runtime for small portable devices.

What power source do I need to supply to the 0.9V-5V input terminals?

A single dry cell or lithium cell within the 0.9V to 5V range can be connected directly to the input pads.

Can I use these modules to charge older USB-A earbuds or Bluetooth speakers?

Yes, the onboard USB-A female port provides a fixed 5V output suitable for charging mobile earbuds and small Bluetooth devices.
