Help us figure out what this battery-powered Google device is on the FCC site
June 23, 2025
Over at theFCC approval site(viaAndroid Police), there’s a mysterious battery-powered Google device. The device has a 3.8V Li-ion battery for power, Bluetooth, dual-band Wi-Fi, and a model number of A4R-H2B.
Our first guess was that this is a battery-powered Home device, possibly aGoogle Home Miniyou can take with you on the go. That theory holds weight due to the model number; all of Google’s Home hardware products have the prefix “A4R-H.”
However, Google justmerged its Home line with Nest, rebranding the Google Home Hub as theGoogle Nest Hub, for example. That means the previous model numbering scheme might be different now.
The battery power also throws us off. Yes, a portable Google Home Mini is certainly possible, but what if its actually an alarm clock, similar to theLenovo Smart Clock? In that case, the battery could be for a backup if you lose power in your home so you don’t have to worry about missing alarms.
There’s also the possibility that this isn’t a Home-related product at all. What if it’s theGoogle Stadia controller, for example? What if it’s a remote forChromecasts, something many people have wanted for years now?
The confidentiality agreement between the FCC and Google will drop for this product in November, so we’ll find out before then what it is. In the meantime, what do you think it might be? Better yet, what do youhopeit might be? Let us know your theories in the comments!
