This is the second one I've tried. It's a lot lighter, and about as big as my galaxy phone. The battery lasts (with once a day charge my phone to full) all week. It might last longer, but I've been using it that long. This has become my primary during the day charger. I like that when my phone is charged, this charger turns off. Some of the other ones don't. So this eliminates over charging, and over heating.

I received this product free/discounted, in return for a honest review. Getting a product to test does not affect what I say. My reviews reflect only my experience with the product and reviews are good or bad only based on how well the product works for me.
