The Raspberry Pi operates on 5V/3A provided through a C-Type port and works efficiently if the device gets the exact power supply. Although supplying the power to the Raspberry Pi device through your mobile charger may work in a few cases, it’s better to acquire an official charger for your device.
Powering a single Raspberry Pi is pretty simple; however, if you want to work on multiple Raspberry Pi devices, you should need a high-capacity power supply option to power them up efficiently.
How to Power Multiple Raspberry Pi
In this article, we will provide several methods through which they can power multiple Raspberry devices quite easily. So, let’s begin introducing each method and leave it up to you to decide which you want to choose.
1: Power Multiple Raspberry Pi Through a USB Hub
A USB hub is the most effective and affordable option for powering up your Raspberry Pi devices as it includes several ports that can deliver exact power to your Raspberry Pi devices and you can turn on your devices all at once. For this reason, you must need to acquire a C-Type cable for each Raspberry Pi device so that you can plug the cable into the ports of a USB hub.

Each port of this hub delivers an output of around 2.4A, which is enough to power your Raspberry Pi devices. If you don’t have a sufficient amount of Type-C power cables, you can purchase them from here.
2: Power Multiple Raspberry Pi By Purchasing Power Adapters
Although the above method is better, however, if you think it won’t best fit according to your needs, you can purchase an official power supply for each Raspberry Pi device from here. Performing this method requires a socket that includes sufficient ports for connecting the power supply for each device.
3: Power Multiple Raspberry Pi Using Breadboard
You can also power up multiple Raspberry Pi devices in parallel from a single power supply using the Breadboard. The reason is voltage remains the same for parallel connections. To do this, you must place your Raspberry Pi devices onto the Breadboard and the GPIO Pin No.2 (for Power Supply) and Pin No.6 (Ground Pin) of each device must be connected to the external power supply of 5V (3A) DC through jumper wires. You can purchase a recommended power supply from here that you can use with BreadBoard. You can also use a mobile charger or official Raspberry Pi power supply by cutting down its Type-C pin and taking out the two wires to connect them to your breadboard. However, you must be careful in connecting these wires to the external power supply because doing it in the wrong way may affect your Raspberry Pi device.
Attaching multiple Raspberry Pi devices with an adequate power supply isn’t difficult once you know your devices’ requirements. Purchasing a USB Hub is a better option; however, you can purchase a power supply for each Raspberry Pi device, which might be costly for a few users. If you don’t want to go with the first two methods, you can create your power hub using the breadboard. For this, you must connect the GPIO Pins 2 and 6 of each Raspberry Pi device with the power supply of 5V DC to power up multiple devices simultaneously.
