A friend of mine asked me to pick up a couple BlackBerry chargers for him and I noticed that the prices had dropped for the relatively new Power Plug style OEM BlackBerry charger. We mentioned the prices of the folding blade OEM wall charger a bit back but these Power Plug USB chargers that come with the newest devices were still pricey. I am not sure when that changed exactly but you can now pick up one of these Power Plug USB charger with the accompanying MicroUSB cable for $5.11 @Amazon with free shipping for orders over $25. It is sold by The Mobile Solutions Company but is fulfilled by Amazon. If you would rather the classic folding blade wall charger you can also get it for $4.59 on Amazon.
