Jackery Fridge Guard Review: A Slim 1kWh Wall-Mount Battery Backup for Your Fridge
The Jackery Fridge Guard is a 1,024Wh LiFePO4 battery that hangs on the wall or stands beside your refrigerator and switches the fridge to battery by itself when the power goes out. It is about 2.6 inches thick, puts out 800W (1,600W peak) and lists a 10ms switchover, and one expansion battery takes it to 2,048Wh. By our math the base unit keeps a typical ENERGY STAR bottom-freezer fridge cold for ~14 hours: enough for an overnight outage, not a full day. Below: the live price, where it is sold (including Costco), runtime math, what published reviews found, and how it compares with the Bluetti Fridge Power.

How the Jackery Fridge Guard Works as a Fridge Backup
Jackery styles the product “FridgeGuard”. It is a battery and inverter in a flat panel, not a portable power station with a handle and a row of ports. Set-up is one plug in each direction:
- Wall → Fridge Guard → fridge. The Fridge Guard plugs into a wall outlet, and the fridge plugs into its single 110V AC outlet (CleanTechnica; The Solar Lab). While the grid is up, wall power runs the fridge and keeps the battery charged. Digital Trends describes a bypass mode that protects battery health once the battery is full (Digital Trends).
- Automatic takeover. When the grid drops, the unit switches the fridge to battery. Jackery lists a 10ms switchover on its Amazon listing and in its launch release (Jackery release; CleanTechnica). A compressor would ride through a slower switch; the fast figure matters more for a router or other electronics.
- Compressor start-up. The 1,600W peak is what Jackery calls “compressor-ready” output, the brief surge a fridge needs when its compressor kicks on. Continuous output is 800W, so this is a one-appliance battery. Jackery says other essentials up to 800W work too, and Digital Trends names home offices, aquariums and CPAP machines (Digital Trends). Check a CPAP’s draw with its maker first.
- Placement. The Amazon listing includes a wall mount. Reviewers describe three positions: on the wall behind or beside the fridge, standing in the gap next to it, or lying flat on top (Digital Trends; The Solar Lab). CleanTechnica lists the panel at 23.6 × 12.8 × 2.6 in and an IP20 rating, which means dry indoor use only.
Why automatic takeover matters for food. The FDA says a closed refrigerator keeps food safe for about 4 hours without power (FDA). With a UPS you don’t have to be home to plug anything in, so an outage that starts overnight or while you’re at work never starts that clock. For the bigger picture on fridge sizes and other batteries, see our guide to running a refrigerator on a battery.
Jackery Fridge Guard Price: Unit and Expansion Bundle on Amazon
Check the live unit price on Amazon: Check price at Amazon →. Jackery also sells it on Amazon with the expansion battery. Prices below are live from Amazon. When we checked on November 8, 2026, both listings were sold by Jackery Inc with an Amazon buy box, but Amazon reported an availability date rather than a plain “In Stock”, so check the delivery estimate on the listing.
| Amazon listing | Capacity | What’s included (per Amazon title) | Price | Amazon |
|---|---|---|---|---|
| Jackery Fridge Guard | 1,024 Wh | Unit + wall mount | Check price at Amazon → | View → |
| Jackery Fridge Guard with Expansion Battery | 2,048 Wh | Unit + expansion battery (mount not mentioned in the title) | Check price at Amazon → | View → |
What the Fridge Guard costs in total
For a fridge-only setup the unit price is most of the cost: it plugs into an ordinary outlet, so you need no electrician, transfer switch or permit. Two extras are worth budgeting for. The first is the expansion battery if your fridge is large or your outages run past a night (see the runtime table below). The second is Jackery’s optional DC input module, which CleanTechnica says you need for solar charging and is sold separately. Holiday sales can move prices, and our Black Friday deal tracker shows today’s prices on the models we follow.
Jackery Fridge Guard at Costco: Where It’s Sold
The Fridge Guard launched in the US as a Costco exclusive. Jackery’s July 17, 2026 release said it was available to Costco members on Costco.com and in select warehouses (Jackery release via GlobeNewswire), and Digital Trends, The Gadgeteer and The Solar Lab all described it as Costco-only at launch (Digital Trends; The Gadgeteer; The Solar Lab).
It is no longer Costco-only. As of November 8, 2026, Jackery sells the unit and the expansion bundle on Amazon itself (seller: Jackery Inc). We could not confirm whether Costco still stocks it online or in a given warehouse, or whether a Costco package matches the Amazon one, so search costco.com for “FridgeGuard” and compare box contents before you choose. For Costco’s regular power-station range, see our Costco solar generator guide.
How Long Will the Jackery Fridge Guard Run a Refrigerator?
What sets runtime is a fridge’s average draw, not its running watts, because the compressor cycles on and off. The yellow EnergyGuide label lists yearly kWh; divide by 8.76 for average watts. The typical figures below are the median annual kWh of certified models in the ENERGY STAR certified refrigerators dataset. Our formula: battery Wh × 0.85 ÷ average watts = hours, with 0.85 allowing for inverter losses. These are planning estimates, not measurements.
| Fridge type (ENERGY STAR median) | Avg draw | Unit (1,024Wh) | + expansion (2,048Wh) |
|---|---|---|---|
| Compact / mini fridge (246 kWh/yr) | ~28 W | ~31 hours | ~2.6 days |
| Top-freezer fridge (363 kWh/yr) | ~41 W | ~21 hours | ~42 hours |
| Bottom-freezer / French-door (560 kWh/yr) | ~64 W | ~14 hours | ~27 hours |
| Side-by-side (640 kWh/yr) | ~73 W | ~12 hours | ~24 hours |
Jackery’s own numbers disagree. The launch release and launch coverage say “up to 15 hours” of fridge backup, or up to 30 hours with the expansion battery (Jackery release; Digital Trends), while Jackery’s Fridge Guard blog post gives about 7.3 hours at a 100W load (Jackery blog). Our formula gives about 8.7 hours at a steady 100W. The gap comes down to what the fridge actually draws on average, which is why we use the same method as every other battery on this site.
One real-world data point. The Solar Lab plugged a full-size kitchen fridge into its unit at about 5 p.m. and found the battery empty by about 8:30 the next morning. It estimates most fridges use about 1,300Wh a day, and concludes the base unit can’t carry an average kitchen fridge through a full 24 hours without the expansion battery (The Solar Lab). That lines up with our table: plan on a night, not a day.
Older fridges use more. ENERGY STAR says an old refrigerator uses about 20% more energy than a certified model on average (ENERGY STAR). Use the kWh on your own EnergyGuide label for the best estimate. If you also need to keep a chest freezer cold, our freezer battery guide has the numbers.
Charging: Wall, Solar and Cold Weather
| Source | Published figure | Notes |
|---|---|---|
| Wall (AC) | 800W (The Solar Lab) | The Solar Lab lists 800W of AC input and reports a full recharge in about 1 hour 20 minutes. CleanTechnica says AC and DC inputs together reach 1,300W. We found no second source for the AC figure alone. |
| Solar | Up to 500W | Through Jackery’s optional DC input module, sold separately; MC4 panels need an adapter (CleanTechnica). The Solar Lab found solar, the expansion battery and car charging share one DC port, so only one can be used at a time. |
| Cold weather | Down to -4°F (-20°C) | The Solar Lab lists charging and discharging down to -20°C. Indoor use only (IP20, per CleanTechnica). |
The shared DC port is the practical catch. If you add the expansion battery, you give up solar charging on that port. For a long outage where you want panels, a regular station with a dedicated solar input fits better (see Fridge Guard vs a regular 1kWh Jackery below, and our winter storm power backup plan).
Jackery Fridge Guard Reviews: What Published Reviewers Found
We do not test units ourselves. This review brings together Jackery’s specs, its Amazon listing and published coverage. The Solar Lab ran the only detailed hands-on review we found; most other coverage is launch reporting built on Jackery’s figures.
- The Solar Lab calls it “a good first attempt at a dedicated refrigerator backup system.” It liked the price compared with the Bluetti Fridge Power, the slim wall-mount design and a bright display that rotates to match how the unit is mounted, and it reports 83% efficiency and a quick recharge. Its criticisms: the unit “automatically powers itself off” after a long period with no load, which could leave a fridge unpowered when the compressor cycles back on (the reviewer suggests a software update could fix it); one DC port is shared by solar, the expansion battery and car charging; there is one AC outlet; and 1,024Wh isn’t enough for a full day on an average kitchen fridge. It recommends the Fridge Guard mainly for budget-focused buyers protecting food through occasional outages (The Solar Lab).
- CleanTechnica focused on design and set-up: plug it into the wall, plug the fridge into it. Its writer expected longer runtime than Jackery’s figure on his own smaller, efficient fridge. It also lists the specs that are hard to find elsewhere, including the single outlet, the 500W DC module and the IP20 rating (CleanTechnica).
- Digital Trends and The Gadgeteer covered the launch, repeating Jackery’s “world’s slimmest refrigerator backup battery” claim and its runtime figures, and noting the Costco exclusive (Digital Trends; The Gadgeteer).
About the auto-shutoff. This is The Solar Lab’s finding alone; we did not find it confirmed or ruled out elsewhere, and Jackery’s materials don’t mention it. Because a fridge is exactly the kind of load that goes quiet for long stretches, check Jackery’s current firmware notes or ask Jackery support before you rely on the unit while you’re away. The Amazon listing is new, so read the latest Amazon customer reviews for owner reports too.
Jackery Fridge Guard vs Bluetti Fridge Power
Bluetti’s Fridge Power takes the same approach, a slim LiFePO4 panel with automatic takeover next to the fridge, at about twice the size. Specs come from our product database; our Bluetti Fridge Power review has its full sources.
| Spec | Jackery Fridge Guard | Bluetti Fridge Power |
|---|---|---|
| Capacity | 1,024Wh LiFePO4 | 2,016Wh LiFePO4 |
| Continuous / peak | 800W / 1,600W | 1,800W / 3,600W |
| UPS switchover | 10ms (Jackery) | Under 10ms (Bluetti) |
| AC outlets | 1 | 2 |
| Maximum capacity | 2,048Wh (1 expansion battery) | 8,064Wh (3 BC200) |
| Solar input | 500W (optional module) | 1,000W |
| Thickness / weight | About 2.6 in / 23 lb | 75mm (about 3 in) / 43.4 lb |
| Bottom-freezer fridge, base unit (our math) | ~14 hours | ~27 hours |
| Score (our scoring) | 80/100 | 85/100 |
| Amazon price | Check price at Amazon → | Check price at Amazon → |
Fridge Guard outlet count: CleanTechnica and The Solar Lab. Fridge Power outlets: APH Networks, The Solar Lab and PhileWeb. The Solar Lab reviewed both and says the Fridge Guard “weighs nearly 20 lbs less than the FridgePower”.
How to choose. The Fridge Power has about twice the battery, more than twice the output, a second outlet and four times the expansion. That makes it the pick for a big French-door fridge, a fridge plus a freezer, a sump pump, or outages that last longer than a night. The Fridge Guard is thinner and about half the weight, which makes it easier to wall-mount, and it suits one ordinary fridge through a typical overnight outage. Compare the live prices above: the bigger question is whether you need a night or a day of runtime.
Fridge Guard vs a Regular 1kWh Jackery Power Station
Jackery sells two regular stations at the same capacity that we already rate: the HomePower 1000 Plus v2 and the Explorer 1000 V2. Specs come from our product database.
| Spec | Jackery Fridge Guard | Jackery HomePower 1000 Plus v2 | Jackery Explorer 1000 V2 |
|---|---|---|---|
| Capacity | 1,024Wh | 1,024Wh | 1,024Wh |
| Continuous / surge | 800W / 1,600W | 1,800W / 3,600W | 1,500W / 3,000W |
| UPS switchover | 10ms (Jackery) | 10ms or less (Jackery) | 20ms or less (Jackery) |
| AC outlets | 1 | 4, on two app-controlled circuits | 3 |
| Expandable | To 2,048Wh | To about 11kWh | No |
| Solar input | 500W (optional module) | 400W | 400W |
| Weight / shape | 23 lb, 2.6 in flat panel | 23.8 lb, box | 23.3 lb, box |
| Score (our scoring) | 80/100 | 88/100 | 93/100 |
| Amazon price | Check price at Amazon → | Check price at Amazon → | $559.00 |
HomePower 1000 Plus v2 outlets and switchover: Jackery’s release and CleanTechnica (see that review). Explorer 1000 V2 switchover: Jackery’s listed spec, via Mr. Solar.
The short answer: on paper, the HomePower 1000 Plus v2 does everything the Fridge Guard does and more. It has the same battery and a similar UPS figure, more than twice the output, four outlets, far more expansion and a dedicated solar input, at a similar weight. That is why it scores higher in our general scoring, which weighs output, ports and expansion. The Fridge Guard wins on placement. It hangs flat on the wall behind or beside the fridge, so it never takes floor or counter space, and it is built to stay plugged in permanently. Pick the Fridge Guard if a tidy, permanent fridge backup is the whole point. Pick a regular station if you also want to run a microwave, charge laptops or carry power out to the garage or campsite.

Verdict
A tidy, automatic overnight backup for one fridge, as long as you know its limits.
The Jackery Fridge Guard puts 1,024Wh, a 10ms automatic takeover and a wall mount into a 2.6-inch panel that disappears behind or beside the fridge. By our math it covers a typical bottom-freezer fridge for ~14 hours, and the expansion battery roughly doubles that. In our scoring it rates 80/100, a score built from published specs, published reviews and the current Amazon price. It gives up points for its single outlet, 800W output, limited expansion and shared solar port. The idle auto-shutoff The Solar Lab reported is worth checking with Jackery before you leave it unattended. If your outages run longer than a night, the Bluetti Fridge Power (85/100) is the bigger purpose-built option. If you want one battery for everything, the HomePower 1000 Plus v2 (88/100) is the more flexible buy.

Frequently Asked Questions
What is the Jackery Fridge Guard?
It is a 1,024Wh LiFePO4 battery and inverter in a panel about 2.6 inches thick, designed to back up a refrigerator. You plug it into the wall and plug the fridge into its single AC outlet; when the grid fails it switches the fridge to battery automatically, in 10ms by Jackery’s figure. It delivers 800W continuous (1,600W peak), comes with a wall mount on the unit-only Amazon listing, and expands to 2,048Wh with one expansion battery.
How much does the Jackery Fridge Guard cost?
The live Amazon price for the unit and for the bundle with the expansion battery is shown in the price table on this page. Because it plugs into an ordinary outlet, there is no electrician, transfer switch or permit to add for a fridge-only setup. The extras to budget for are the expansion battery if you need more than a night of runtime, and Jackery’s optional DC input module if you want solar charging.
Is the Jackery Fridge Guard sold at Costco?
It launched in the US as a Costco exclusive, sold to members on Costco.com and in select warehouses, according to Jackery’s July 2026 release. Since then Jackery has also listed it on Amazon, where it was sold by Jackery Inc when we checked on November 8, 2026. We could not confirm current Costco stock, so search costco.com for “FridgeGuard” and compare what’s in the box with the Amazon listing.
How long will the Jackery Fridge Guard run a refrigerator?
By our math (1,024Wh × 0.85 ÷ average draw), ~21 hours for a typical ENERGY STAR top-freezer fridge, ~14 hours for a bottom-freezer or French-door model and ~12 hours for a side-by-side. The expansion battery roughly doubles each figure. Jackery’s own claims range from about 7.3 hours at a 100W load to “up to 15 hours”, and The Solar Lab’s full-size kitchen fridge ran from about 5 p.m. to 8:30 a.m. Older fridges use more.
What do Jackery Fridge Guard reviews say?
The Solar Lab, which ran the most detailed hands-on review we found, called it a good first attempt at a dedicated fridge backup. It praised the price, slim wall-mount design and rotating display, and reported 83% efficiency. It criticized an automatic power-off after long periods with no load, a single AC outlet, one DC port shared by solar and the expansion battery, and a battery too small for a full day on an average kitchen fridge. Launch coverage from CleanTechnica and Digital Trends focused on the slim design and easy set-up.
Jackery Fridge Guard vs Bluetti Fridge Power: which is better?
They take the same approach at different sizes. The Fridge Guard has 1,024Wh, 800W (1,600W peak), one AC outlet and expansion to 2,048Wh, in a 2.6-inch body that weighs about 23 lb. The Bluetti Fridge Power has 2,016Wh, 1,800W, two outlets and expansion to 8,064Wh, at about 43 lb. Both list a switchover of about 10ms. The Fridge Guard suits one ordinary fridge through an overnight outage; the Fridge Power suits big fridges, a fridge plus a freezer, a sump pump or longer outages.
