The Echo Dot is Amazon’s smallest smart speaker, but it normally needs a power cable. This battery case lets you cut the cord and use your Dot wherever you have Wi-Fi. The case clips onto the bottom of the speaker, with a U-shaped adapter delivering power. The 7,500mAh battery provides 10-15 hours’ usage on a full charge.

The internal battery also acts as a power bank for your other devices. You can charge your phone or laptop via the USB-C port, while LED indicators tell you how much power is left. You can even use this case with other smart home devices, such as the Google Home Mini.

The Smart Battery Case is now 32% off MSRP at $26.99 (Orig. $39.99).
