We are living in a world run by different kinds of electronic devices and gadgets. Digital cameras, video camcorders, Smartphones, tablets, wireless headset and laptops are some of these. And it’s now a reality that most of the time these devices are becoming a necessity in our job and in our day-to-day living. In this case we are often plagued with device charging problem that often gets in the way in the things that we need to do. To solve this problem we are in constant search for different ways to fast charge these devices. In this post, I will show you the do’s and don’ts when trying to fast charge your gadgets. Read on.
Since most of the electronic gadgets and devices available today now supports charging via USB ports, we just blindly use this to our advantage. Worst thing is we often utilized USB hubs thinking that it can fast charge your smartphones, tablets and digital cameras. Did you know that most USB ports found today are just USB 2.0 or below?
The USB 2.0 standard only delivers 0.5 A (amperes) of juice, so avoid using USB hubs because it tends to be slower in charging your devices. Let’s have a good example. If you connect two USB devices in a 4 port USB hub delivering 0.5 A (500mA), each devices will only get 0.25 A (250mA). This is very little compared to what wall chargers can provide ranging from 0.75 up to 2 A. If a wall charger has been provided for your smartphones and tablets, use it more often. It will not only fast charge your device but the juice will last much longer.
So what’s left for USB devices without wall chargers? Though you can use a USB wall charger from another device, it is a good habit to first check the ‘Output’ ratings before using it. Normally most USB wall charger and similar devices like the PlugBug (available from different electronics store) has a rating of 5V and 0.5A to 1.2 A (500mA – 1,200mA). So make it sure that you read your manuals first that comes with your device or read the ratings printed directly on the USB wall chargers. If you have the output ratings above then I can say that it’s safe to use it.

The PowerGen Dual Port USB AC / Travel charger charges TWO of electronic devices simultaneously, eg. iPad, iPhone, iPod, MP3 Players, Digital Cameras, PDAs, Mobile Phones and USB for power. It is compact with high quality finish and comes with full 1 year limited warranty.
For laptop, ultrabooks and desktop PC owners that have a USB 3.0 port included, you can utilize this port that can fast charge your smartphones and tablets. Note that USB 3.0 standard can deliver much juice to your gadgets of up to 0.9 A (900mA) charging power.
Whenever I want to fast charge my wireless headset, I use my iPad 2 charger as an alternative. The iPad charger can deliver 1.2 A (1,200 mA) of juice allowing me to have my wireless headset available in just a couple of minutes.
