The label on a power supply may not be a reliable guide to the actual voltage it supplies under varying conditions. Spurious marks of conformity to standards may be present; in one case it was reported that “Chinese manufacturers were submitting well-engineered electrical products to obtain conformity testing reports, but then removing non-essential components in production to reduce costs”.

In most external plug-in “wall wart” power adapters commonly used for low-power consumer electronics devices were of linear design, as well as supplies built into some equipment. More efficient power supply designs could cut that usage in half”.

What I’ve found is eventually mth mark the power supply will stop charging all together or the connecting pins get pushed in and you need to wiggle the cable to make the laptop charge. The last one only lasted about hawwing year.
