Erroned output indication on phones chargers !

[hassenman]

hi all
I purshased some old phone chargers with the intention to use their output voltage in my own circuits , but when i tried to test them with my multimeter they do not give the mentioned voltage , for example , a siemens charger written down : output : 5 v
is giving 9.6 v . another which output is supposed to be 5.5 is giving 9 v .
is that normal ?? or whats going wrong ??
thanks for ur help .
