Welcome to the Nintendo Power Supply section. We will show you which power supplies work with your classic Nintendo systems. In this section.
NOTE: When it comes to power supplies, the two areas that are of the most concern are VOLTS OUTPUT and AMPS OUTPUT. The VOLTAGE should always be the right amount for the system you are hooking up (most systems list their requirements on the bottom). The AMPS on the other hand you have a little leeway with, you can safely use a power supply that provides MORE amps than the system requires, but not (much) fewer AMPS. So if your system wants .85 amps, it would be OK to use 1.2 amps, as the system can adjust its needs.
For use with original Nintendo Game Boy
OUTPUT: 6V 7W
This is the power supply that could be purchased separately for the original Nintendo Game Boy. In addition to allowing you to plug in the wall and play it contains rechargeable batteries. So you could remove the cord that plugs into the wall and carry this guy around as power source for your Game Boy. Unfortunately these rechargeable NiHM Batteries have most likely dies by now and won’t hold a charge, but they are fairly easy to replace.
For use with Nintendo Game Boy Pocket & Game Boy Color
INPUT: AC120V 60Hz 3W
OUTPUT: 3V DC 300 mA
This power supply was first released with the Nintendo Game Boy Pocket. When the Game Boy Color came out it used the same power supply. They did change the case to say that it works with the Pocket and the Color, but if your case just says Game Boy Pocket on it, no worries, it will work just fine with the Color.
