I bought this power supply to use with various brands and models of Android TV boxes and SBCs. Most of them work fine on the supplied 3 amps. There are some SBCs like the Odroid XU4 board that require 4 amps or more. The main connector for this is 5.5mm x 2.1mm, which is the standard for most 5 volt power supplies. With this model you get adapters for most of the input jacks you are likely to come across. I want all adapters to be straight instead of straight and some to be right angle. I purchased an 8 amp 5 volt DC power supply with the same 5.5mm x 2.1mm output plug to use the adapters that came with this unit on devices that require more than 3 amps. If you only need a power supply for a specific version of the Raspberry Pi, you can buy a power supply for your specific board for less. With the included adapters, this single power supply can be used for all versions of the Raspberry Pi, eliminating the need for multiple power supplies. This small power supply has many advantages and I can only name a few disadvantages from my point of view. I already mentioned that I would prefer all adapters to be straight. This is my personal preference and many users will appreciate 90 degree adapters. The second disadvantage is that it only has 3 amps. If this little device had a 4 amp output it could power every SBC I have. I guess you can't have everything but this power supply with the included adapters is a fantastic deal at the current price.
