This looks like more comprehensive specs for the same model:

The stuff that you need to worry about is:
● ripple voltage: Vpp≤1%
--> 50 mV p-p at 5V
● Digital display: three digit digit display.
● Display Resolution: 0.1V / 0.01A. ● Display accuracy: 100mV / 10mA ± 2digits.
This is a "regulated" power supply and "regulation" isn't even specified. 50 mV p-p is pretty respectable for a switching power supply.
I concur.
One thing that isn't obvious is that you can't seem to preset a current.
A digital supply I have has a Volts/amps selector, course fine adjusts, a power switch, and a front panel ground connection.
The binding posts are (+, earth and -), so difficult to use a dual banana. I have an analog supply that basically has the same things, but the arrangement of the banana's is a triagular pattern standard spaced.
This,
