Can other Samsung phone chargers be used with this phone and vice versa?

Hey everyone. I wanted to know if other Samsung phone chargers work for this phone and vice versa? I own an Impression (A877) while my wife owns a Solstice (A887). We travel a lot, so we only carry one charger at different locations of our stay. Both of our chargers are OEM Samsung products as they are straight out of the retail box. I sometimes will use her charger for my phone, and she will use my charger for her phone. Is this okay?

The chargers are able to connect fine with no problems, meaning that they seem to be the correct pin. Anyone know if the chargers interchangeable for these phones? I am assuming as long as these chargers are OEM Samsung products, are able to fit properly in each other's phone, and actually working successfully, they should be okay.

Oh yeah, I was also browsing through each of the phone's user guides/manuals, but I did not find anything that mentioned if these chargers were compatible with each other. The only thing that it mentioned was to avoid non-OEM chargers as they run a risk for damaging the phone.

I guess I was just worried about damage from wrong phone chargers or incompatible ones.

Thanks!

The solstice, eternity, propel, omnia, behold, impression, highlight and many others use the same usb and charging cable.  Most everything after the a707 sync now uses the same cable.
