Can’t decide between the Amazon Echo Dot deal for $34.99 and the Amazon Tap deal for $79.99? Well, you can have the best of both worlds for less than the price of the Amazon Tap. That’s because the VAUX Speaker & Portable Battery for the Echo Dot just went on sale for $39.96. It essentially converts the Echo Dot into an Amazon Tap by adding a speaker and rechargeable battery. I’ve never tried the product myself, so I can’t speak to its quality, but it has a great 4.2 star review rating. It claims to have 6 hours of battery life and includes a pair of 52mm Speaker Drivers. While it’s not as small and sleek as the Amazon Tap, it seems like the ultimate option to have portability coupled with the better far field microphone array in the Echo Dot. A look at the device’s price history reveals it has never been on sale before today.
