Hi and welcome, meanies. I have something called a Kensington Power Pack that works very well. There are others that are similar, but I can't remember their names right now. There are some power packs on eBay that might be cheaper, too. If you search the forum for Kensington, you will probably see mine and others too. The Google search way down at the bottom left of the page works very well.
Johnnie B., if you're talking about a charger that plugs into the wall and has a USB slot, then probably yes, if it's rated that high.
