5V 600mA DC-DC Step-Up Booster Module

This DC-DC Step-Up Booster Module solves a common problem in battery-powered projects: most usable batteries, like a single lithium-ion cell (nominal 3.3V) or AAA cells, don’t naturally supply the 5V that phones and USB devices expect. This non-isolated boost converter steps that lower battery voltage up to a stable 5V output, letting you build a working charger or power source from whatever cell you have on hand.

What makes this module particularly useful is its wide input range – it continues to operate with input voltage as low as 0.9V, though efficiency improves as the input voltage rises. Onboard LED indicators show operating status and battery input level at a glance, and the USB-A output port means you simply connect your battery’s positive and negative terminals to the board and plug your device straight into the USB port, no soldering or berg strips required. Note that the module itself has no short-circuit protection, so pairing it with a lithium-ion cell that has its own protection circuit is recommended.

• Output Voltage – 5.1V to 5.2V
• Input Voltage – 1V to 5V (works down to 0.9V)
• Switching Frequency – 500kHz
• Output Interface – USB-A port
• Converter Type – Non-isolated boost converter
• Indicators – LEDs for status and input voltage
• Rated Current – 600mA

Simple to wire and genuinely useful for low-voltage battery projects, this 5V 600mA DC-DC Step-Up Booster Module turns almost any single cell into a usable USB power source.
