Recently purchased this laptop power supply, tested it with a multimeter and it produces exactly the correct voltage and voltage according to the display. minus point: low quality cable and crocodile clamps. Replace these for better quality. All in all I am satisfied with this lap food, good quality for the price.
A good toy, useful for anyone who plays with electronics and electricity. Good price-quality ratio! A small light toy that I ordered easily and it came very quickly, In the shipping box it is well protected! I recommend!
The source works, the ripple is slightly better than a similarly priced switched source. It is problematic to set the voltage exactly. The setting of current and voltage with a connected load does not show adjusted values, but real values. The set voltage can only be seen if the current protection is not limiting. The adjustable current limit can only be seen in case of a larger load, for example a short circuit. The current limit setting is very roughly 0.3-5 A on less than one revolution. Current regulation reacts late. With a limit of 0.5A and a consumption of 0.75A, the reaction of the current limitation after more than one second. At a limit of 0.5A and a consumption of 3A, the current limitation reacts in 100ms.
