Bests & Worsts Reviews from Amazon

No reason. This product is described as 5W, 1 amp. The Kindle line is mainly 5V (4.8V, what's the difference) and around 1 amp, which is 5 Watts (5W). Why the mystery, guys? Also, this deal is for US 110V market only? I travel. I like that the previous simple FIRE charger was universal (i.e. 100V-240v). I like that the first Kindle charger was also universal. What are you people doing? Or, is it that the copywriter in this case just doesn't understand? For those who don't understand the details of electricity, ANY device will tell you what it needs to feed. Voltage (V) is one thing to look at and your charger needs to say something within the range of 100 and 240 volts to meet your device need. As far as AMPS (A). If your device says it needs 1.8 A. It's perfectly fine to buy a charger that has a rating higher than that. Like 2 Amps. The device will only drink as much as it needs. A device that needs 1.8 A plugged into a 2 A charger just means the charger is taking a nap. Just avoid situations where your device needs more Amps than a charger can provide. It won't necessarily explode but it will extend charge times and is generally not recommended.
