  • It took me several minutes to figure out that blue means fully charged and red means charging since this charger did not come with any instructions. It takes several hours (usually 2-3 hours) to charge my Nexus S 4G stock battery and Anker replacement battery. The really nice thing about this product though is that you can adjust it to fit several different batteries, so hopefully it will work with my next phone. It's small enough to fit in your pocket and is definitely travel-friendly.
  • I find this product very useful and innovative. I love the idea that I can charge my mobile phone batteries from different phones with the same device. Great price too. So far it's been working well. It's accepted spare batteries for both my Samsung Nexus S and HTC nexus one.Pros: Charges batteries of different sizes for different phonesCons: not found any yet.I very highly recommend this product without reservations.
