Lost or broke your Gateway netbook charger? No worries! This 40W AC adapter is made to work with Gateway LT40 series netbooks like the LT4004u, LT4008u, LT4009u, and LT4010u. It delivers 19 volts of power, just like the original, and comes with a power cable so you're ready to plug and play. It's unbranded/generic but built to do the job—perfect as a backup or replacement. The max output is 40 watts, which is plenty to keep your netbook charged up. It's brand new in packaging, though maybe not the fancy retail box. No MPN or UPC, but it's compatible and reliable. Don't let a dead battery slow you down—grab this adapter and get back to browsing, working, or streaming!
