Cainuo via Amazon offers the Tofu LCD 40-watt 8-Port USB Smart Charger in White for $24.99. Coupon code "BZSNUSGP" cuts it to $17.49. Plus, Prime members receive free shipping. That's tied with last week's mention, $20 off, and the lowest price we could find. It features a backlit LCD status screen, iSmart charging technology, multiple built-in protection methods, and 4-foot removable power cable. Deal ends December 31.

Update: The price has increased to $25.69 before coupon, $17.98 after.
