I already own a larger model Wanptek bench top power supply. The reason I wanted this one is that it is smaller and will have room on my already cluttered bench. The other supply is great and has performed well, but I mainly work with 5V circuits and it is overkill. This little supply is perfect for my needs! The size is just right! It can stay on my workbench without being in the way. It comes with the necessary cables and an instruction manual. It was packaged extremely well. It could have survived a 20' drop the way it was packaged. Very little chance of it getting damaged in shipment. Wanptek may not be a brand you have heard of, but they have been around for a while and seem to manufacture quality products. Like I said earlier, this is not the first Wanptek power supply I have owned. If you need a quality power supply that isn't the size of a shoe box, then this is it!
