Too bad the Amazon Kindle charger isn't in the mix, it is my favorite just because it is so tiny and relatively high output. Would have liked to see same analysis for it.

I just got a Kindle PaperWhite and it did not come with a charger, just a USB cable to plug into a computer for power.

  The Kindle charger is sold separately, and you could probably get a much cheaper one than the $20 they are selling for as it's a standard micro USB port. My paperwhite USB is the same as my Logitec mouse and Android phone. Makes charging much easier as I keep them all on the same desk as I work.

    Yea, I would not have used one anyway and am happier having a cheaper Kindle. I think I have only charged it once, great battery life on that thing.

I've got 3 USB chargers in the house, including a Kindle charger, and none of them inter-operate at all. Ridiculous.

  Out of curiousity whereabouts are you based? I'm in the UK and have about 5 different USB chargers, and they all play nice with each other.

    I live in the US. The chargers look like they'll work together. For example, the Kindle charger will make my pocket camera light up its charging light, but after a minute or so, it goes out, as if the charge has completed. In fact, though, the battery is still dead. The other combinations of cell phone / camera / Kindle chargers are similar.

  I dunno, I mix iPhone, iPad, Kindle, Samsung (Nexus) and Griffin chargers all the time, bring only one of them (typically iPad) on the trips, and it works out completely fine. I think that Kindle and Griffin are the slowest though.

when it comes to charge times, is there any difference between a cable from my computer or kindle/plug charger?

  If you check the article you will see that every charger has an Amp rating (like: 2 Amperes). This has a direct impact on the charging rate (provided that the device can handle it). Charging a device at 5V@2A is twice as fast as charging it at 5V@1A. An USB 2.0 plug can usually provide 500mA (0.5A), so the USB charging is slower than using the plug. In real life charging is also limited by the battery temperature for safety reasons. If the battery becomes too hot during charging (because of the environment temperature, poor ventilation or just because the device has a huge consumption while charging) the charging will stop and will start again when the battery cools down. This is why we do not see chargers with bigger Amp rating: the batteries are limited to a current that doesn't get them too hot.
