If you love being able to ask Alexa, the Amazon Echo Dot Smart Battery Case is an essential upgrade. This compact accessory makes your speaker truly wireless, with a battery life of up to 15 hours. Available in white and black, the case is now just $26.99 (Orig. $39.99) at 9to5Toys Specials.
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.
