Don't power up your Raspberry Pi with any old cable! This is a task that you will need to be mindful of as some models are very stringent in their required input.
We offer a range of Raspberry Pi boards, some of which may require different power supplies. For example, the Raspberry Pi 3 power supply is rated at 5V @ 2.5A and it is recommended for the Raspberry Pi 3B+ as a minimum for stability. Why's that? While how much current (mA) it requires is dependent on what you hook up to it or what it is used for, a 5V @ 2.5A power supply is sufficient for most applications, including the use of its 4 USB ports.
However, the Raspberry Pi 4 requires 5V @ 3A and a cable with a USB-C connector! That said, according to the Raspberry Pi Foundation, "A good quality 2.5A power supply can be used if downstream USB peripherals consume less than 500mA in total." So, another solution is to use an excellent quality 5V @ 2.5A power supply like one of these, together with a Micro USB(F) to USB-C(M) Adapter like these.
