Overview

A multi-day power outage can spoil $300 or more in refrigerated and frozen food — the kind of loss most homeowners only think about after the freezer has already thawed. BLUETTI’s FridgePower is a purpose-built UPS battery designed to sit behind or beside a refrigerator, stay plugged in and mostly forgotten about, and take over automatically the moment the grid drops.

The 75mm-thin chassis is the real story here: instead of taking up floor space like a typical camping power station, it slides into the gap behind or beside a fridge and mostly disappears from view. It’s available on Amazon.ca for around $1,199 CAD, and ships as a single 2,016Wh unit that can be stacked with BlueCell 200 expansion modules for Canadian households that want more than a day of coverage — a real consideration during a winter ice storm in Ontario or Quebec, or a summer grid strain out west.

Key Specifications

BLUETTI FridgePower Battery Capacity & Runtime

The base 2,016Wh LiFePO4 pack is sized around a single fridge, not a whole house, and real-world runtime tests reflect how much that number depends on the appliance connected to it. Reviewed.com found FridgePower kept a full-size refrigerator running for more than 30 hours after the main power supply was disconnected, while Basic-Tutorials measured just under 23 hours powering one fridge with no expansion module attached. TechRadar’s test running two fridges off a FridgePower paired with a single BlueCell 200 add-on landed around 37 hours combined.

That spread makes sense once compressor draw enters the picture — an older or larger fridge pulls more continuous wattage than a compact one, and the built-in Battery Backup Guide comparisons peg a modern Energy Star fridge at 100–200Wh per day, well within FridgePower’s range for a short outage. For anything longer than a day or two, or for households that also want to keep a chest freezer or sump pump alive, stacking BlueCell 200 modules pushes total capacity to 4,032Wh or 8,064Wh, though each module adds meaningfully to the total cost.

Switchover Speed & Reliability

The DualGuard UPS system is the core of what FridgePower actually does: it detects a mains outage and switches the connected appliance to battery power in roughly 10 milliseconds, fast enough that a compressor doesn’t stall or need to restart from a cold stop. Four selectable modes — Standard, PV Priority, Time of Use, and Customized — let it prioritize solar input, charge during off-peak utility rates, or run on a fixed schedule depending on the household’s setup.

Standby power draw is rated at just 4W, low enough that leaving the unit plugged in and idle for months between outages costs only a few dollars a year in electricity. Paired with a 10-year rated lifespan on the LiFePO4 cells, the pitch is a battery that’s installed once and largely ignored until it’s needed — a different design goal than a portable power station meant to be unplugged, carried around, and recharged on a regular cycle.

Installation & Space-Saving Design

Setup is close to plug-and-play: connect the fridge to FridgePower’s outlet, plug FridgePower into the wall, and the unit is monitoring for outages from that point on. At 75mm thick, it’s built to slide into the narrow gap behind a refrigerator, mount to a nearby wall, or lie flat in a cabinet — none of which is realistic with a typical boxy power station shaped more like a rolling cooler.

That slim profile comes with a tradeoff worth noting: at 43.4 lbs, the unit is denser than its thin shape suggests, and positioning it behind a fully loaded fridge for the first time is a two-person job in most kitchens. Once it’s in place, though, it’s designed to stay there rather than get moved around the way a camping-style power station would.

App & Smart Home Connectivity

The BLUETTI app adds a proactive layer on top of the hardware: its Storm Alert feature pushes severe-weather warnings and can automatically kick off a fast charge ahead of a forecasted storm, so the battery starts an outage at full capacity rather than wherever it happened to sit. That’s a meaningfully different approach than most backup batteries, which only react once the power has already gone out.

Alexa and Google Home integration lets a household check battery level and estimated runtime by voice without opening the app, and an optional magnetic FridgePower Screen accessory mounts to the fridge door or a nearby counter for an always-on physical readout of battery level, runtime, and weather alerts.

How Does It Stack Up Against the Competition?

FridgePower competes less with other slim UPS units — there aren’t many — and more with general-purpose portable power stations that get repurposed for fridge backup.

Is the BLUETTI FridgePower Worth It?

FridgePower makes the most sense for a Canadian household that has one specific worry — losing a fridge or freezer full of food during an outage — and wants a battery that installs once, hides behind the appliance, and reacts on its own. The combination of a genuine 10ms automatic switchover and a form factor that doesn’t take over a kitchen corner is hard to match with a general power station repurposed for the same job, and it’s sold directly through Amazon.ca.

Anyone who needs broader backup power — running a laptop, router, and a few lights alongside the fridge, or taking the battery along on camping trips — gets more flexibility per dollar from something like the Anker SOLIX S2000, which offers similar capacity at a lower price without FridgePower’s dedicated install. FridgePower’s base capacity also covers roughly a day of runtime; stretching to a multi-day outage means paying for BlueCell expansion modules on top of the initial price.
