Have you wondered why your smartphone or tablet doesn't charge rapidly when you plug it into the USB port on your computer? Have you purchased some third party chargers for your car, motorcycle, boat or airplane, or a solar charger, and they won't charge your toys? My book will explain the secrets of USB port battery charging which are not explained in the manufacturers documentation. More
Just about every modern computer peripheral device uses the USB port. Practically all smartphones, tablets, GPS navigation units and portable electronic toys with rechargeable batteries have chargers that use the USB cable to connect the device to a wall charger and to a computer. However, the USB port on a computer was never designed to charge a battery and any of today's portable devices that require charging power above 2.5 watts will not charge rapidly on a computer USB port. The Secrets Of USB Battery Charging will explain why your devices will not "Rapid" charge on your computer USB ports and most third party chargers and alternatives to work around the limitations of the USB port power specifications.
The latest edition of this book has added emphasis on using an iPad in the cockpit of aircraft and gives pilots valuable insight on keeping an iPad charged while on for long periods of time.

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.
