Who this is for
You rent or live in a small home. The power goes out and you want two things to keep working: your refrigerator and your Wi-Fi. No permanent installation, no gas generator indoors, nothing you need an electrician for.
The short answer
Buy a power station in the ~1,000 Wh class. Under the stated assumptions, that covers a full-size fridge plus Wi-Fi for roughly 11–13 hours—about an overnight outage.
The math
These are calculated estimates, not measured results. A refrigerator is modeled at 150 W while running and a 40% duty cycle, or 60 W average. A router adds 10 W. Usable AC energy is modeled as rated Wh × 0.9 battery reserve × 0.85 inverter efficiency, or about rated Wh × 0.77.
| Class | Example | Usable energy | Estimated runtime |
|---|
| ~500 Wh | EcoFlow RIVER 2 Max, 512 Wh | ~395 Wh | ~5.5 hours |
| ~1,000 Wh | BLUETTI AC180, 1,152 Wh | ~885 Wh | ~12.5 hours |
| ~1,000 Wh | Anker SOLIX C1000, 1,056 Wh | ~810 Wh | ~11.5 hours |
| ~1,000 Wh | EcoFlow DELTA 2, 1,024 Wh | ~790 Wh | ~11 hours |
| ~1,000 Wh | Jackery 1000 v2, 1,070 Wh | ~825 Wh | ~12 hours |
| ~2,000 Wh | BLUETTI Elite 200 V2, 2,073 Wh | ~1,595 Wh | ~22 hours |
A refrigerator compressor can briefly draw 800–1,200 W when starting. The tracked ~1,000 Wh-class models supply 1,500–1,800 W continuously. A 500 W-output unit is the one that may struggle.
The options, cheapest suitable first
BLUETTI AC180: 1,152 Wh, 1,800 W, $449 verified at bluettipower.com on September 14, 2026. It is the least expensive suitable price verified in this snapshot.
Anker SOLIX C1000: 1,056 Wh, 1,800 W, recent $397–$500 range, but price not verified on September 14, 2026. Recheck before buying. It is lighter and has a claimed 58-minute wall recharge.
EcoFlow DELTA 2: 1,024 Wh, 1,800 W. Delisted from EcoFlow US on September 14, 2026 (replaced by DELTA 3); recent range was $349–$449.
Jackery Explorer 1000 v2: 1,070 Wh, 1,500 W, $559 verified at jackery.com on September 14, 2026.
Jackery Explorer 1000 Plus: 1,264 Wh, 2,000 W, $619 verified at jackery.com on September 14, 2026; expandable to 5,056 Wh.
Reasons not to buy
- Do not buy a ~500 Wh station for a full-size fridge. The modeled runtime is roughly 5–6 hours, and 500 W continuous output can struggle with startup.
- Do not buy 2,000 Wh+ “just in case.” The tracked BLUETTI class weighs 53.4 lb and is oversized for the overnight case unless outages regularly exceed 12 hours.
- Skip the solar panel for rare outages. It is more relevant to frequent multi-day outages, camping, or daily off-grid use.
Total configuration cost
For fridge + router, the station alone does the job. Budget the station price plus tax. A 14-gauge or thicker extension cord is optional if the unit sits away from the kitchen.
Methodology
- Specifications come from manufacturer pages and manuals.
- Prices carry verification dates.
- Runtime figures are calculated estimates with stated assumptions, not measured results.
- TrueWatt has not owned, installed, or lab-tested these products.
- The recommendation favors the least expensive suitable option the evidence supports.
Anker SOLIX C1000 vs BLUETTI AC180

Who this is for
You have narrowed it to two 1,000 Wh-class stations. Both can cover the modeled overnight fridge-and-router case. The tiebreaker is fit, not hype.
The short answer
At equal prices, the AC180 offers slightly more capacity and a verified $449 snapshot price. If the C1000 verifies under about $449 when you buy, its lower weight, six AC outlets, and fast wall recharge make it compelling.
Head-to-head
| Spec | Anker SOLIX C1000 | BLUETTI AC180 |
|---|
| Capacity | 1,056 Wh LFP | 1,152 Wh LFP |
| Continuous output | 1,800 W | 1,800 W |
| Load feature* | 2,400 W SurgePad | 2,700 W Power Lifting |
| Weight | 28.4 lb | 35.3 lb |
| Dimensions | 14.8 × 8.07 × 10.5 in | 13.4 × 9.7 × 12.5 in |
| AC outlets | 6 | 4 |
| Warranty | 5 years, per Anker Amazon listing | 5 years + 90-day express replacement |
| Price | Unverified September 14; recent $397–$500 range | $449 at bluettipower.com, September 14 |
Who each suits
Choose the C1000 if you will carry it often, need six AC outlets, or value the claimed sub-hour wall recharge. Choose the AC180 if you want the verified $449 snapshot price, slightly more capacity, and its express-replacement promise.
The runtime math
C1000: 1,056 × 0.77 ≈ 813 usable Wh ÷ 70 W ≈ 11.5 hours. AC180: 1,152 × 0.77 ≈ 887 usable Wh ÷ 70 W ≈ 12.5 hours. Calculated estimates, not measured results.
Reasons not to buy
C1000: price was not verified on September 14, 2026; confirm before buying. No expansion-battery support was documented. AC180: it is nearly 7 lb heavier, has only four AC outlets, and its return policy was not verified in this research session. Neither: both are undersized for regular outages longer than about 12 hours and oversized for only Wi-Fi, laptop, and phones.
Methodology
- Specifications from manufacturer pages and manuals.
- Prices carry verification dates.
- Runtime is calculated with the stated 0.77 usable-energy assumption.
- No firsthand testing is claimed.
Watts vs watt-hours, explained for backup power
Published September 14, 2026 · Prices checked September 14, 2026 · Next planned review: September 21, 2026

The short answer
Watts (W) tell you what can run at the same time. Watt-hours (Wh) tell you how long it runs. Watts are the width of the pipe; watt-hours are the size of the tank.
Why the distinction matters
A laptop around 60 W plus a monitor around 30 W is about a 90 W load. A 300 W-output station can handle it. But 90 W for ten hours requires 900 Wh of usable energy—roughly 1,170 Wh rated under the 0.77 assumption. Output was not the binding constraint; capacity was.
The runtime formula
Hours ≈ (rated Wh × 0.77) ÷ load in watts. The 0.77 models a 10% battery reserve and 15% inverter loss. It is an estimate, not a measured universal constant.
Three worked examples
Working from home: router 10 W + laptop 60 W = 70 W. EcoFlow RIVER 2 Max: 512 Wh × 0.77 = 394 usable Wh; 394 ÷ 70 ≈ 5.6 hours.
Fridge + Wi-Fi: fridge 60 W average + router 10 W = 70 W. BLUETTI AC180: 1,152 Wh × 0.77 = 887 usable Wh; 887 ÷ 70 ≈ 12.5 hours.
Phones: assuming roughly 15 Wh per phone battery, 394 usable Wh is about 26 full charges. Phone charging is small next to a refrigerator load.
Reasons not to buy
- Do not buy on watts alone. A 2,000 W-output, 500 Wh-capacity unit could run a space heater only briefly.
- Do not buy capacity you will never use. Router + laptop for 2–3 hours fits a much smaller unit than a 2,000 Wh station.
- Do not treat advertised Wh as fully usable. Every station reserves energy and loses some to conversion; the examples model those losses.
Methodology
- Specifications from manufacturer pages and manuals.
- Prices carry verification dates.
- Examples are calculations, not firsthand test results.
- No ownership, installation, or lab testing is claimed.
