Free stuff isn't easy to come by in 2026. Unless, of course, you know where to look. Amazon likes to hide free stuff in plain sight, like this Anker Nano charging block.
As of April 8, when you purchase a pair of Anker Soundcore Sleep A30 Special earbuds at Amazon for $199.99, you can claim a free Anker Nano USB-C fast-charging block. Once you add the Sleep A30 buds to your cart, head to this promotional page or click on "How to claim" underneath the Prime logo where it says "Get 1 free item when you buy 1 select item(s)." Since you've already added the earbuds to your cart, go ahead and tick the box for "Benefit items" on the left side of your screen (in the middle if you're on mobile). Then add the Anker Nano USB-C charger block to your cart. You'll see the savings reflected at checkout.
Obviously, that's a lot of money to spend just to get a free charging block. But if you're already shopping for a premium pair of sleep earbuds, you might as well take advantage of the free gift.
The Sleep A30 Special earbuds are our favorite amongst sleep earbuds. Not only do they offer active noise cancellation, but also decent battery life (8-10 hours with ANC), Calm app integration, and a design that's comfortable for side sleepers. Mashable's tester Bethany Allard writes, "They're certainly the best overall pick for anyone looking for sleep earbuds suited to most any sleep setting."
