This is a simple, yet elegant battery gauge that tells you exactly what you want to know–the percentage of your battery remaining. The picture to the side will change according to the power source; it will show a plug when the battery is on AC power, and just a battery when no AC power is available.
In the options menu, you can change the opacity of the gadget, so you can keep it always on top of your windows without it being too obtrusive. It’s so handy to just be able to glance up and see how much battery is remaining!
