About at the FCC approval site (via Android Police), there is a mysterious battery powered Google device. The device features a 3.8V Li-ion battery for power, Bluetooth, dual-band Wi-Fi and a model number A4R-H2B.
We first suggested that it be a battery powered home appliance, possibly a Google Home Mini You can go with you on the road. The theory holds weight because of the model number; All the products of Google Hardware for Home have the prefix "A4R-H."
The battery power also drops us off. Yes, a portable Google Home Mini is definitely possible, but what if it's actually an alarm clock, similar to Lenovo Smart Clock? In that case, the battery can be a backup if you lose power in your home, so you don't have to worry about the missing alarms.
There is also the possibility that it is not at all a home-related product. What if it Google Stages controller, for example? What if it's a distance for Chromecasts, something many people have wanted for years?
The confidentiality agreement between the FCC and Google will fall for this product in November, so we will first find out what it is. In the meantime, what do you think it can be? Better still, what do you do? hope it could be? Let us know your theories in the comments!
