Reading the description I got the impression that the unit came with 2.5 and 2.1 adapters. This is not the case. I does have a female adapter with it and I just cut off the 2.1 end from what I was replacing and used the adapter with terminals with my old cord. This is OK. I actually have a bit longer cord which I can use to an advantage. I tinned the ends of the old cord which is necessary to get a good connection using the adapter.

The QD connector is great for testing items so you don't have to wire and unwire all the time.
I haven't used this yet, as I plan to convert it into a heavy duty power supply for an Atari 800XL computer (with the addition of a 7-pin semi-circular DIN plug). It looks like it will be a good power supply so I'll give it five stars now. my rating is subject to how it performs once I do use it.
The adapter piece that has the screw-down wire terminals on my shipment are reversed. The terminal that is clearly marked negative (-) is the 5 volt hot terminal and visa versa. What an egregious error. I wasted a whole day troubleshooting a non-working LED strip application and it was all caused by this ridiculous defect. This is like buying a car and finding the brakes control the throttle.
This is a very good quality 5Volt - 5Amp (25-Watts) power supply. I highly recommend this 5Volt power supply if you require a 5V power supply for your 5V application.
Working fine. No issues.
5V 5A works great! ONE WARNING....the adapter with screw terminals has the + & - listed on it backwards to what the power supply puts out. My relay boards did not power up so I put my meter on it and was showing -5V so I reversed them and poof everything works and it now shows +5V.
excellent product
