I want to get a new phone......but my criteria starts with the charger

We already have Motorola phones and they use the MINI USB CHARGERS. So I want to try a new phone, but I want to make sure it uses the same chargers (because we have those in the house and car already).
When shopping online, this doesn't seem to be mentioned in the spcs

I went to Best Buy yesterday and found ONE phone that did use the same charger, but it was hard to tell about most of them because those tiny side panels didn't seem to open...
Sooooo......does anyone know how to find out which phones use this type of charger? We aren't looking for the fanciest or newest phones....so going to retail stores may not be that helpful. Thanks for any suggestions
