FUTUROSP 170W 20V 8.5A Lenovo ThinkPad Charger

FUTUROSP 170W 20V 8.5A laptop charger is an OEM replacement power adapter engineered to safely power compatible Lenovo ThinkPad models with a square yellow tip.

This replacement adapter delivers up to 170 watts (20V, 8.5A) of output and works interchangeably with 135W (20V, 6.75A) configurations, giving you a reliable, high-power option when the original adapter is lost, damaged, or you need a spare. It is built for broad voltage input (100–240V) so it operates worldwide and carries CE, FCC, and RoHS certifications for key safety and regulatory compliance. Please note this item is an OEM charger—not an original Lenovo-branded unit—and is optimized for compatibility with a wide range of ThinkPad P, T, W and X1 series laptops.
