Excellent info that the manufacturers of smartphones, tablets and toys leave out about their chargers. And what's with none of them being compatible with other makers toys? Found out that with a 12 watt charger like the one for the iPad 4 or All the latest Samsung devices and a "smart dongle" I can charge any device. No need to take multiple chargers on trips.

Had to write a review because... this book could have saved me money had I read it earlier! I would not have wasted money on several USB car chargers for cellphones over the years.

It turns out that USB devices aren't what we may all think, because USB wasn't originally intended to be used to charge up peoples' phones & tablets and other tech appliances. Now that these things that I depend on require more and more power to charge up with, it seems to be the case that the cellphone makers are designing methods to pump lots of power through usb connectors and they aren't talking to each other yet. Here's where this book comes into play: There are so many small usb power adapters out there - like cute flourescent colored ones at stores like bed bath & beyond at the checkout counter - and these things aren't always going to do what you think because of the differing methods of charging that the phone and tablet manufacturers have put into place in order to make usb do what they need in order to simply charge the devices' battery.

This book is a fairly quick read and makes it easy to for non-technical people to gain an understanding of why these devices we depend on are not charging in the way we need even though we pay for what we expect to be a simple charging devices. If you spend the small amount of money that this book costs, chances are that it could save you money (and more importantly, frustration from dead cellphone or tablet batteries) in the long run.
