Walmart offers the Mainstays 5-watt LED Desk Lamp with Qi Wireless Charging in several colors (Silver pictured) for $10. Opt for in-store pickup to avoid the $5.99 shipping fee. That's $2 under our December mention, $10 off, and the lowest price we've seen for an LED lamp with wireless charging capability. It's compatible with most Qi-enabled devices and features an adjustable gooseneck and USB charging port.
