Therefore, it is recommended to purchase a power supply unit (PSU) that is designed for the Raspberry Pi from an authorized merchant such as where the Raspberry Pi was purchased. In general, these chargers don’t produce the exact voltage and amperage written on the label.Īlso, the newer model 4 requires more amperage than the older models and most phone chargers do not provide the required amount. It is NOT recommended to use a phone charger to power the Raspberry Pi computer. Using a Phone Charger to Power a Raspberry Pi To do this, you’ll need a USB cable that has either a Micro USB connector or a USB-C connector, depending on the Raspberry Pi model you’re using, and a standard USB connector to connect to the main computer.Ĭheck the above table for the type of connectors to use with each model.įor example, you’ll need that kind of cable with a Raspberry Pi 4 or 400. You’ll probably get the lightening symbol with a few USB accessories or if you ask too much to your Pi. However, it’s a convenient way to start it if you have nothing else available.

The reason for this is that the device will get its power from the main electrical source and not from the Raspberry Pi computer, which won’t be able to provide enough power to the device. However, if you want to add additional storage devices, such a Solid-State Drive (SSD, very useful to make your Raspberry Pi runs faster) or Hard Disk Drive (HDD), it is recommended to use a powered USB hub instead of attaching it directly to the Raspberry Pi. ![]() You should purchase a PSU that meets the requirements listed in the above table as the under power could cause damage to the micro-SD memory card or the Raspberry Pi. If a lightning bolt icon appears at the top right of the screen on Raspberry Pi OS, it means that your power supply is not providing enough power to the Raspberry Pi. This way you are sure it respects this requirement and that it will work like a charm with your Raspberry Pi.įor Raspberry Pi 3 and older, you can use this one from CanaKit, which is specifically made for Raspberry Pi. For example, on Raspberry 4 and 400 it will be this one on Amazon. The easiest way to avoid any issue with your power supply is to grab the official one for your specific model.
