Review on Enhanced Power Tip A46 for Apple, Samsung, and Sony MP3 Players by Jay Matlock

This is the ONLY attachment you will likely ever need as the universal USB support gives you the option to use your own cable, without having to buy new attachments when you change phones. I bought it on 3/2012 and am currently charging my phone with this tip – 10/2013. It's the best value you can get, paired with the universal igo power strip (AA powered) and some Tenergy Premium batteries (2500mAh x 2 = 5000mAh per pair) and you have a better charger with more capacity than 99% of the electricity supply on the market, at half the price!
