Many parents, like us, purchased the Amazon Kindle Fire for their children for the holidays. Amazon was running a great sale that put it at $129 for a few weeks at the end of 2012. The intention of this article is to help you understand some of the major issues and challenges of using the Kindle Fire.
First, the Fire does not ship with a charger. It includes a USB to Micro USB cable but not a charging brick to plug into the wall. This is actually quite an issue because the usual USB bricks that you may have accumulated for charging things like phones, the Nintendo DS, or iPods aren’t powerful enough to charge the Kindle Fire. For instance, the charger that comes with the iPhone or the iPod touch is 5 Volts, 1 Amp. You really need a 2 Amp charger for the Kindle, like the one that comes with the iPad or other tablets.
