Gameboy Advance SP

As the world's smallest video-game platform, the Game Boy Advance SP is also the first to use a built-in rechargeable battery.

Many decried the original Game Boy Advance's reflective LCD screen and its reliance on external light sources. The Game Boy Advance SP's main feature--optional backlighting--fixes this complaint nicely, but it's the wealth of other features that makes this system so surprisingly good.

At first look, you might think the SP is a sleek travel alarm clock. When closed, it's just as tall and deep as the original GBA, but only half as wide. Due to its clamshell design, the screen is always protected from everyday scratches. A small button in the center of the console turns on the backlighting element for use in low-light situations, like in a moving car.

.The SP comes with a well-designed power adapter that recharges a built-in battery; its prongs fold in for easier storage. Our informal tests found that it takes about four hours to fully charge (you can even play it while it's plugged in and charging), and the battery lasts about 11 hours with the backlighting constantly on--your results may vary. Using the backlighting less often will conserve battery power.

The new Game Boy Advance SP works essentially the same way previous Game Boy Advance models have--and plays the same selection of games--but adds a number of thoughtful features to the design. The most obvious difference you'll see is the lighting feature built into the screen, so you can play in low-light situations without bulky external game lights that too often leave a hot spot on the screen or fail to reach the corners. You can shut off this internal light to squeeze a little more playing time out of the power source if you're in a situation with enough light to see the SP's reflective screen.

Speaking of power sources, the SP comes with a rechargeable lithium-ion battery that provides between 10 and 18 hours of gameplay from a three-hour charge. Also, the new clamshell design will offer protection for the screen from scratches when it's all closed up. --Porter B. Hall
