Review on Cable Matters 2-Pack Retractable Micro USB Cable - 2.5 Feet: Tangle-Free Charging on the Go by Kevin Bigelow

Perfect for keeping in your pocket, car, purse or anywhere you need a backup charger. I buy them for the second time. I've had the first one for over 5 years now and although I haven't used it much as it was a spare that revived my car and bag I was very grateful to it. I wouldn't guess it's a regular daily charger, but I think it might be. I also have to say that while I had to replace my 5 year old, it was because they stopped cleaning and that made the whole point for me. The actual charging parts still worked.
