As I predicted, Amazon's new Kindle Fire HDX tablets were a big hit over the holidays, and in my mind is a better tablet than the iPad . Not only is it far cheaper than the iPad – starting at an insanely cheap $229 – but they also comes in 7-inch and 8.9-inch varieties and are packed with high-end parts. Unless you're already invested in the iOS ecosystem, then the Kindle Fire HDX is a tablet worth looking at. And even if you are already an iPhone or iPad user, or own an Android-powered smartphone or tablet, the Kindle Fire HDX makes an awesome second tablet for browsing and content consumption

But a great tablet can be made even better by augmenting it with accessories, and there are some awesome add-ons for Amazon's flagship tablet.

Note: Some of these accessories are specific for the Kindle Fire HDX while other will work with any tablet or smartphone.

This is Amazon's official fast charger for the Kindle tablets. The PowerFast charger pumps out 9W/1.8A of power, and is far beefier than the standard 5W charger.

The speaker already built into the Kindle Fire HDX are awesome, but sometimes you need a little more oomph in the audio department.

There's nothing worse than getting a scratch on your screen, but cheap screen protectors not only don't provide much protection but also degrade the viewing experience considerably.

It is made from the same protective film material used to protect military aircrafts, helicopters and space shuttles. MilitaryShield is also equipped with "self-healing" properties to maximize the protection. It also peels off easy without leaving a residue.

Despite the Kindle Fire HDX having an awesome set of speakers, sometimes you just want to listen to something in peace or in private.

I've been through literally hundreds of headphones over the years and the Sennheiser PMX 685i are my favorites. Not only are they rugged and sweatproof – ideal for the gym – but they are comfortable and give out great sound.
