5x DC-DC Boost Converter Module – 0.9-5V To 5V 600mA – USB Charger Step Up Board

If you're messing around with electronics and need to bump a low voltage up to 5V for USB devices, this 5-pack of boost converter modules is handy.

They take an input as low as 0.9V and step it up to a steady 5V at up to 600mA.

Perfect for battery-powered projects where you need to charge a phone or power a microcontroller from a single cell or low-voltage source.

They're unbranded, but the specs are solid: 0.9-5V in, 5V out, 600mA max.

New old stock, no MPN.

Five pieces give you extras for multiple projects or backups.
