[Tfug] Opine: Bricks, warts or...?

I'm going to hate myself for extending another ill-defined no answer
good enough Bexley thread but...

Snip...

No you don't have to buy a special cradle to charge your cell phone from
USB.  That is, I don't.  My Motorola phone charger has a small wall wart
on one side and a USB mini plug on the other.  If I'm at home or
traveling, I have the AC charger.  If I'm at the office or a friend's
house and need a boost, I just hook up via USB for a charge.  It's the
best of both worlds...people not around computers can use the supplied
AC adapter and people who spend a lot of time around computers can
mooch from the USB port if they prefer.

Here are adapter pics:

As far as your other comment about needing a cord to power up, don't be
dense.  Of course you'll need a cord of some sort.
