Strengths: Higher wattage output than standard charger.
Summary: I bought two of these from one of the storefronts, shentech. Supposedly, it was new, but I have a feeling it was a refurb because of QA stickers and a set of numbers which I believe is the manufacturing date (2005.07) on the brick. It stopped working after about 2 weeks. The other one is still working.
I have not noticed if it charges the battery faster or not.
