The number of devices I own that require USB power keeps increasing. And so do the number of USB power sources to run and charge these devices.
The problem with many USB power sources is the limited current for each port. Some devices with four ports will share an 2 amps. This means multiple devices can require more than 2 amps and weird things can happen. I found this out recently when I plugged three devices into the same 4-port USB power source and all three devices started acting strange with flashing screens, noises indicating a charge and no charge. The problem was not enough current (amps) to support those three devices combined.
What i needed I found in the Anker 6-port, 60 watt, power supply. Each port has 2 amps of power. Check it out:
There are other brands that look similar. Be sure of the power rating for each port.

Here’s an important tip if you are using Skype or similar service on a computer with more than one monitor: Keep the Skype video window on the same monitor upon which the camera is mounted. I recently had a couple Skype sessions and found they I got confused about where I should be looking — at the camera or at the Skype video window. Placing camera and window on the same monitor will eliminate this confusion and allow you to keep focused on the other person.

I’ve written extensively about power in my e-book MobileWriter. No power, no computing. No power, no Internet. Perhaps I also think about power more than most computer users because of my amateur radio activity, which also depends on power.
I was coming up short on mobile charging for the MacBook Pro so I searched around and found a great solution that plugs into the car lighter. I’ve test this device out in the vehicle and in a 12-volt indoor power supply that has a cigarette lighter socket.
The device I found is a WeCharger Ultra-Compact Portable MacBook Car Charger.
Find it here on Amazon:
Not all computer keyboards (laptop or desktop) have backlighting. I found an innovative solution in a dual-head LED music stand light.
Each LED light is at the end of a gooseneck arm for easy positioning.
The music stand light I purchased runs off AC and batteries. Others run off USB or just batteries.
The low setting is just right for showing the keys in dark places. USB lights that I previously tried were just too bright.
Here are some examples from Amazon:
