Our son Jon and I discussed getting his mom a reader/tablet for her birthday (St Patrick's Day no less). I had asked Jeanne if she'd like a reader/ tablet for her birthday. I'd seen a "Cruz", 7" Reader at Tigerdirect for $120. She said she wanted to wait since the product type was too young and likely much more expensive than it would become. Jon called a couple of days later and said he had a Kindle someone just gave him that had no charger. He said he'd give it to me to give Jeanne. We figured "how difficult can it be to get a charger?". Yesterday he just sent it home with his mom who was at their place to see the light of all of our lives, our only grandson Liam. So I started investigating a charger for it. It is a thoroughly intact 2nd generation 6" Kindle. The current one is 3rd generation I believe. It works except it's battery is too far discharged to do any reading. It turns out it uses a USB charger/ interface port to charge. That means any 1 amp USB adapter should work, right? I mean USB is USB right? WRONG PILGRIM, here's where it gets interesting. There are a plethora of USB connections and standards. See the Wikipedia page which covers it in depth. Here's the standard connector end views.
I bought Jeanne a Blue Microphone "EyeBall" web-cam for her PC for Christmas which had only a 3' cable for use with laptops. I ended up having to order a 6' USB A male -Mini-B male cable + a spare to make it work . I had forgotten which non ordinary type it was. I also have a D,C,AAA,AA battery charger with a USB charging port. I figured I was set for the Kindle charging. Yeah , sure, guess again. Wonder of wonders, the spare cable i had didn't fit the Kindle on the small end. It needs a Micro-B not a Mini-B like I already had.
Then I remembered the Universal Samsung Cell Phone Car Chargers both Jeanne and I have. There is a micro USB connector adapter in the kit I was able to use to charge my Bluetooth headset with. It is a Micro-B male which fits the Kindle just fine.
I still have to get a USB A male to Micro-B male cable to use to charge the Kindle indoors but at least I've navigated the Stormy Sea of USB successfully.
