When most people picture a home battery backup, they imagine something bulky and industrial-looking — a utilitarian box that sits in the basement or garage, doing its job but never winning any beauty contests. Jackery's new FridgeGuard is trying to change that narrative, and it's even got the hardware to back up the ambition: the device just won the iF DESIGN AWARD 2026 for its sleek, 2.6-inch-thick profile that the company is calling the world's slimmest refrigerator battery.
For many households, the refrigerator is the most critical appliance to keep running during a power outage — it's where medications are stored, leftovers are kept safe, and for families with young children, formula and milk matter more than most people realize. But traditional backup solutions often feel clunky and intrusive. Jackery set out to change that by designing the FridgeGuard specifically around how refrigerators actually work, combining what the company calls FridgeSafe Technology with an inverter that can handle the compressor surges that other batteries might struggle with.
The device delivers 800 watts of continuous power with a 1,600-watt peak capacity — exactly the kind of punch a compressor needs to get going. With less than a 10-millisecond switchover, it works as an uninterrupted power supply, keeping sensitive equipment protected from the grid anomalies that can damage electronics mid-operation. A 1,024-watt-hour capacity provides roughly 15 hours of backup for a full-sized refrigerator, and for those who need more runtime, an expansion battery can double that to 30 hours. At just 23 pounds and measuring 23.6 by 12.8 inches, it can sit on top of the refrigerator, mount on a wall, or simply rest against the wall behind it — unobtrusively.
The circular display on the front communicates everything homeowners might want to know: remaining battery percentage, input and output power, charge and discharge time estimates, Wi-Fi status, and whether Time-of-Use mode is active for those looking to save on electricity costs by charging during off-peak hours. The silver metallic finish is specifically designed to complement stainless steel appliances, and it's molded into the case rather than painted on, ensuring it stays looking good for years.
Setup requires nothing more than plugging the unit into a wall outlet and plugging the refrigerator into the FridgeGuard — no complicated installation. The Jackery App allows users to monitor status, set delay start times, and manage the device alongside other Jackery products for smart energy management. If the battery is fully depleted but AC power has returned, the FridgeGuard can bypass the battery entirely, sending power directly through without interruption.
Beyond refrigerators, the device opens up possibilities for window air conditioners, 3D printers, home theaters, and even medical equipment like CPAP machines — anywhere maintaining an electricity supply matters. It's a reminder that the best technology isn't just powerful; it fits into people's lives in ways that make them actually want to use it. The FridgeGuard is now available for purchase, bringing a new kind of backup battery into homes that might never have made room for one before.
