Jackery FridgeGuard: 2.63-inch battery keeps fridges running 15 hours

Key Takeaways

• FridgeGuard measures 2.63 inches thick, designed to fit behind or beside refrigerators without visibility
• 10ms UPS switchover prevents food spoilage by keeping compressors running through grid failures
• Available June 22nd exclusively at Costco for $559.99, with optional 1kWh expansion battery

Jackery has entered the fridge-battery market with FridgeGuard, a power station measuring just 2.63 inches thick that the company calls the world's slimmest. The device is built to sit on top of, behind, or beside a refrigerator and automatically kick in during power outages with a 10-millisecond UPS switchover. At $559.99, it launches June 22nd as a Costco exclusive in the US.

The product targets a specific pain point: food spoilage during multi-day outages. A typical American fridge-freezer combo will run for about 10 hours on the 1kWh LFP battery, or roughly 15 hours under optimal conditions according to Jackery's testing. Adding the optional 1kWh expansion battery doubles that runtime to 20 hours.

Why does form factor matter for fridge batteries?

Traditional portable power stations look like they belong on a construction site. Bright orange housings, chunky handles, industrial vents. They work fine in a garage or basement, but most kitchens don't have floor space for a bulky generator.

FridgeGuard's 67mm thickness lets it slide into the gap between a fridge and the wall, or lie flat on top of standard refrigerators. The design language is deliberately muted: white and gray tones, minimal branding. "We wanted to change the narrative that backup power has to look like an industrial job-site tool," a Jackery product lead said. "The FridgeGuard is designed to be as at home in your kitchen as a high-end appliance."

The 10ms switchover explained

Modern smart refrigerators are sensitive to hard power cycles. A sudden cutoff can corrupt onboard computers, reset temperature settings, or trigger compressor protection modes that delay restart. The sub-10ms UPS switchover prevents this by maintaining power continuity through the brief gap when grid power fails.

This matters more than raw capacity for certain use cases. A fridge that loses power for 50 milliseconds might stay cold, but its control board could still malfunction. FridgeGuard's near-instant transfer keeps electronics stable.

What else can FridgeGuard power?

Despite the name, nothing limits FridgeGuard to refrigerators. The 800W continuous output (1600W peak) handles most household devices. Jackery suggests installing it in a bedroom to run a CPAP machine during blackouts, or in a living room for a TV and gaming console. The 40dB fan noise matches a typical refrigerator, so it won't disrupt sleep.

The 6,000 charge cycle rating on the LiFePO4 battery chemistry means daily charging would last over 16 years before significant degradation. For most homes that experience a few outages annually, the battery will outlast the appliances it protects.

How does FridgeGuard compare to competitors?

Jackery arrives late to this category. Biolite pioneered the slim fridge battery concept but won't ship until August. Bluetti has similar products, and premium newcomer Pila targets design-conscious buyers willing to pay more for aesthetics.

The $560 Costco price undercuts several competitors, though discussions on r/homeautomation question whether the slim profile justifies any premium over traditional portable power stations with higher capacity. Power users on HackerNews specifically praised the UPS switchover time, noting that budget alternatives often have 20-50ms gaps that can still trip sensitive electronics.

Availability and pricing

FridgeGuard launches June 22nd exclusively at Costco in the United States. The $559.99 member price includes the base 1kWh unit. Jackery has not announced pricing or availability for the expansion battery, or whether broader retail distribution will follow the Costco exclusive period.

Frequently Asked Questions

How long will Jackery FridgeGuard power a refrigerator?

The 1kWh battery powers a typical US fridge-freezer combo for 10-15 hours. Adding the optional 1kWh expansion battery extends runtime to approximately 20 hours.

What is UPS switchover and why does 10ms matter?

UPS (Uninterruptible Power Supply) switchover is the time between grid failure and battery takeover. At 10 milliseconds, FridgeGuard prevents the power gap that can corrupt smart fridge electronics or trigger compressor protection delays.

Can FridgeGuard power devices other than refrigerators?

Yes. The 800W continuous output works for CPAP machines, TVs, gaming consoles, fish tank pumps, and similar devices. The 40dB noise level makes it suitable for bedroom installation.

Where can I buy Jackery FridgeGuard?

FridgeGuard launches June 22nd, 2026, exclusively at Costco in the US for $559.99 (member price). Broader retail availability has not been announced.

How long will the FridgeGuard battery last before replacement?

The LiFePO4 battery is rated for 6,000 charge cycles. For a home experiencing occasional outages, this translates to over 16 years of service life.
