Logitech Wireless Mouse Marathon M705 lets you power on... and on. It uses less power than comparable wireless mice from other companies, so you'll go up to three full years between battery changes.~ And it uses a tiny wireless receiver that stays plugged in to your computer, so your mouse is ready to go-whenever, wherever, and for as long as it takes. Plus, hyper-fast scrolling means you'll fly through long documents to find what you need in a flash. Advanced Optical Tracking means you'll get smooth, responsive cursor control. And the sculpted, right-hand shape means you'll be as comfortable finishing up as you were getting started.

Power your compatible Samsung device without cables or cords using this Samsung SMS EP-PG920IBUGUS wireless charger, which replenishes battery power in as little as 4 hours. Overload protection provides defense against damage.
