Most people across the world already own a portable computer, and that would be their smartphone. If we’re talking about an actual computer with an operating system that we’re more familiar with using, then you’d use a laptop. The Raspberry Pi is one of the minor types of portable computer you can own because it has a processor, graphics processor, and memory on just a single board. When you think of a desktop computer, you likely think of a large piece of tech, but Raspberry Pi shrinks all of that down to a credit card-sized computer.
One of the best parts of the Raspberry Pi is that it’s a low power consumption device, with the Raspberry Pi 3 being powered from a Micro-USB port and the Raspberry Pi 4 being powered from a USB-C port. Both of these ports are the most accessible to use because most people likely already own a cable to use with either of these models. Since Raspberry Pi is such a small and easy-to-be portable device that you can very quickly power, using a power bank is a great option that you can use to power it.
Most might think that choosing a power bank for the Raspberry Pi is difficult because you have to choose a power bank with a specific port with a certain charging speed. That’s not the case at all. In this guide, we’re covering power banks that are compatible with the Raspberry Pi, and the gist of it is that you can use a USB-A port to power a Raspberry Pi as long as the ports on the power bank have a 5V/2.4A charge output or higher. You have to make sure that you’re using a Micro-USB to USB-A cable for the Raspberry Pi 3 and a USB-C to USB-A cable for the Raspberry Pi 4, as both of these models use different ports to be powered from.
MAXOAK AC10 26,756mAh USB-C Power Bank with AC Outlet
This MAXOAK power bank may be a bit much for what you’re looking for; however, we think this charger fits well with charging your Raspberry Pi while being portable. The most notable reason for this is because this power bank has a 100W AC outlet, and if you want to use either the Micro-USB Raspberry Pi 1, 2, or 3 power supply or the Raspberry Pi 4’s USB-C power supply with a power bank to make sure that you can charge, then a power bank with an AC outlet is a good idea to have.
You have to turn on the power bank and plug your power supply into the AC outlet, and you can charge your Raspberry Pi.
However, if you don’t have a power supply, you can charge your Raspberry Pi via USB-A ports or the USB-C Power Delivery port. The USB-A ports feature Quick Charge but don’t let that scare you, as they won’t damage your Pi and will supply enough charging power. You can also use the USB-C port to power a Raspberry Pi 4 because it uses a USB-C port to be powered from, but you will need a USB-C to USB-C cable to do so. Older Raspberry Pi models cannot charge via the USB-C port because they have a Micro-USB power port.
Along with the charging and powering options, this MAXOAK power bank has a 26,756mAh power capacity that can power the Pi for many hours. A 20,000mAh power capacity or more should be the target capacity when it comes to powering your Raspberry Pi because even though it’s not a heavy power usage device, you still want to be able to use it constantly without having to worry about losing power.

UGREEN 10,000mAh Power Bank with Built-in USB-C Cable
This UGREEN power bank doesn’t have the same high power capacity as the MAXOAK charger we mentioned because it has a 10,000mAh power capacity. So it won’t last as long, but a 10,000mAh power capacity is still going to last you many hours to power your Raspberry Pi.
This UGREEN portable charger is great for charging the Raspberry Pi 4 because it features a built-in USB-C cable, so as long as the power bank is charged up, you can power your Raspberry Pi 4. Even though this power bank does not have a Micro-USB built-in cable, you can still use the USB-A port to power older models that use a Micro-USB port.
This power bank also has a 20W USB-C Power Delivery port that can be used to power your Raspberry Pi 4 right out of the box because included with the power bank is a USB-C to USB-C cable and a USB-C to USB-A cable. When you’re not using the built-in cable, it conceals directly into the power bank and makes portability easier.

JIGA 30,000mAh 3 Output and 3 Input Power Bank
If you’re searching for a very high-capacity power bank at a lower cost that can power your Raspberry Pi, then this JIGA power bank is one of your best options. The charger has a 30,000mAh power capacity, and with this much power, you won’t have to worry about recharging the power bank for a few days.
There are three outputs and three input ports on the power bank. The three outputs ports are all the same, with them being USB-A ports, and each of them has a 5V/2.1A (10W) charging speed, which is just enough to power the Raspberry Pi.
The three input ports are all different, including USB-C, Lightning, and Micro-USB input ports. Each input port has the same 10W recharging speed, so it doesn’t matter which one you use to recharge the power bank.

Crave 50,000mAh Power Bank
This Crave PowerPack portable charger may be more than what you’re looking for, and that’s because it’s a 50,000mAh power bank that has two USB-C Power Delivery ports and two USB-A Quick Charge ports. With a 50,0000mAh power capacity, you can power your Raspberry Pi for many days, or even a few weeks, depending on how often you’re using the power bank to power your Raspberry Pi. This much power can also be used for charging other devices such as smartphones, tablets, and laptops.
Charging power is more than what you’ll need to power a Raspberry Pi for a week or more. One of the USB-C PD ports has an 18W charge rate, and the other has a 60W Power Delivery charging speed. You can use either USB-C ports to power the Raspberry Pi 4 or use one of the USB-A ports. If you want to power older Raspberry Pi models, you have to use the USB-A ports on this Crave power bank with a Micro-USB to USB-A cable.
This Crave portable charger comes with a 45W Power Delivery charger that you can use to recharge it with, and you’re going to need it when it comes to recharging a 50,000mAh power capacity. The power bank is not as small as many other power banks that you’ve used or seen, so you won’t be able to place this one in your pocket.

Anker PowerCore 26800 3 Output and Dual Input Power Bank
This Anker power bank is a great high-capacity portable charger that also provides enough power while still being incredibly small that you won’t have problems being mobile with it. The PowerCore 26800 has, you guessed it, a 26,800mAh power capacity, so it can last a long time when powering your Raspberry Pi.
The PowerCore 26800 has three USB-A ports that each have a 5V/3.0A (15W) output, and that’s an ample amount of power for the Raspberry Pi. The better part of the output charging is that the power bank has a 30W max output, so you can have two Raspberry Pi computers being powered simultaneously, and we might say three, but that can depend on each of the power draw the three. You are safe to power two, though, as there’s enough power to go around.
This Anker power bank also has two Micro-USB input ports that can be used simultaneously to recharge the power bank at 4A (20W) because each input port has a 2A (10W) recharge rate. The power bank does include two Micro-USB cables so that you can recharge it at its max speed right out of the box.
