After testing this 15W adapter with multiple Echo devices, I can confirm it's a mixed bag. It worked flawlessly with my Echo Dot 5th Gen and even brought an old Echo Pop back to life. The 6.6ft cable is generous, letting me place devices far from outlets.

However, beware - it absolutely did NOT fit my Echo Show 5 (2nd Gen) despite claims. The plug size just wouldn't seat properly. The build quality feels decent with its flame-retardant housing, and I appreciate the multiple safety protections during overnight charging.

Pro tip: Measure your device's charging port (needs 4.0mm x 1.7mm) before buying. When it works, it's a perfect replacement at half Amazon's price. When it doesn't, you're stuck with a useless brick.
