Most power banks will work with any phone. The biggest factor in whether you can use it with your phone is the cable. If the cable you're using doesn't fit the power supply, you can almost certainly buy one that will. Most often, such problems are faced owners of iphone xr bu 128, therefore, special attention should be paid to the connection cable so that the smartphone can work with the power bank.
Input ports
The input ports are used to charge the power bank. Typically this is micro USB or USB-C and you will usually find that a charging cable is included and can be plugged into any USB-A power adapter or into a USB port on your laptop for example.
Micro USB (input)
This is a popular type of cable for charging batteries, older smartphones, and other small devices, so there's a good chance you already have these cables in your home. Unlike USB-C and Lightning, micro USB cables need to be connected correctly, which can sometimes be a problem.
Lightning (input)
This is Apple branded cable since iPhone 5. Any iPhone can be powered from the power bank using this cable. Like USB-C, it is reversible, so it can be connected in any way. Models with Lightning inputs may be right for you if you're an Apple user and want to keep the number of cables you need to a minimum. There have been rumors for years that Apple might drop the Lightning cable in future releases. And after the decision of the European Commission, in a year all new models of the brand will be with a different type of port.
Output ports
Output ports are used to transfer power from the power supply to your devices. This is usually one or more classic USB-A ports. They let you plug in your own charger cable, which means you can probably use whatever cable you're already using to charge your device.
Some power supplies come with an integrated output cable that cannot be removed. This is usually an optional output, so it shouldn't affect you if you plan to use other types of cables as well.
USB-A (Out)
This port is designed for the classic thick USB cable. Although USB-A ports are slowly disappearing from laptops, they are still one of the most popular and versatile cable types.
Almost all power supplies have at least one USB-A output.
USB-C (in/out)
This is the latest USB standard used in most new Android phones. Unlike the other connectors we mentioned, USB-C can be used as both an input and output port. This type of cable supports "power delivery" (more on that later). USB-C connections are also reversible, so there's no way to plug them upside down.
We also measure and evaluate the distance between outlets. Connector spacing isn't usually an issue, but it can prevent you from getting the most out of your PSU if you're using short or awkwardly shaped cables.
