Query: Extra charger for my phone

I bought this item because my RAZR phone battery was only holding a charge for 6-8 hours (just like all RAZR batteries.) I plugged one in at my workplace and placed another one in my basement home office so I wouldn't have to go running upstairs to juice up when the low-battery warning started chirping. The chargers work great, and are cheap as dirt-it's too bad I needed to use them so often however. Since ordering them, I replaced the battery with a high-capacity battery which lasts for days, but now my slim phone is the size of a brick. C'est la vie.
