Pre-release note (October 12, 2026): the S5000 ships October 27. Every S5000 figure below is Anker's own published specification or our arithmetic on it. No independent measurements exist yet, and we don't run hands-on tests. We'll update this page when the unit is listed and priced at retail.
You see "5kWh for $2,499" and "power your home for 48 hours," and it sounds like a generator replacement at half the price. Then you read the footnotes. The $2,499.99 is a launch price; the list price is $3,599.99. The 10,000-cycle rating is to 60% capacity. And the 48-hour home Anker tested was a fridge, a Wi-Fi router, a coffee maker, some lights, and a phone, not your whole house.
None of that makes the S5000 a bad buy. On paper it's the biggest single box we've covered: 5,024Wh, 4,500W of 120/240V output, and a 97-lb frame on wheels. It just needs the same arithmetic as everything else.
The three footnotes
1. The price. Anker lists the S5000 at $2,499.99 at launch and $3,599.99 MSRP, on sale October 27 at AnkerSOLIX.com and Amazon. A launch bonus runs for buyers who sign up October 9–26 and buy October 27–November 9. At launch, that's about $0.50 per Wh; at list, about $0.72 per Wh ($ ÷ 5,024Wh). Judge it at the price you'll actually pay.
2. The cycle rating. Anker rates 6,000 cycles to 80% capacity and 10,000 cycles to 60%. Its 15-year life estimate assumes one or two cycles a day. Compare 6,000-to-80% against other stations' ratings; the 10,000 figure measures something else. That matches the 6,000-cycle rating of the Bluetti Apex 300 (currently $1699.00 · see on Amazon), the longest we list.
3. The 48 hours. "Power your home for 48 hours" comes from Anker's own test load: a fridge, router, coffee maker, lights, and a phone. Anker's separate fridge-only figure is up to 86 hours, measured on a 700L fridge in a 77°F room. Both are manufacturer lab results. Your hours depend on what you plug in. The table below does the math for common loads.
S5000 vs the home-backup stations we track
Every figure is the manufacturer's rating unless marked as our arithmetic. The S5000 isn't in our price tracker yet because it has no retail listing; the other three link to their recently checked prices in the recommendations at the end.
| Spec | Anker SOLIX S5000 | EcoFlow Delta Pro 3 | Anker SOLIX F3000 | Bluetti Apex 300 |
|---|---|---|---|---|
| Rated capacity | 5,024Wh | 4,096Wh | 3,072Wh | 2,764Wh |
| Usable capacity (× 0.85) | ~4,270Wh | ~3,480Wh | ~2,610Wh | ~2,350Wh |
| Running watts | 4,500W | 4,000W | 3,000W | 3,840W |
| Surge watts | 8,000W | 8,000W | 6,000W | 7,680W |
| Output voltage | 120/240V | 120/240V | 120V | 120/240V |
| Rated cycle life | 6,000 to 80% | 4,000 | 3,000 | 6,000 |
| Max solar input | 3,000W (1,000W + 2,000W inputs) | 2,600W | 1,200W | 2,400W |
| Advertised UPS switchover | ≤10ms | 10ms | 20ms | "0ms or 20ms," outlet-dependent |
| Expansion | To 30kWh | To 48kWh | To 24kWh | Expandable (see review) |
| Weight | 97 lbs | 113.5 lbs | 79.6 lbs | 81.6 lbs |
Usable Wh = rated Wh × 0.85 (inverter loss, applied once — how we calculate runtime).
The S5000 leads on capacity, running watts, and solar input, ties the Delta Pro 3 on surge and switchover, and comes in 16.5 lbs lighter. The Delta Pro 3 keeps two real advantages: a 48kWh expansion ceiling against the S5000's 30kWh, and a retail track record you can check today.
Jackery's Explorer 5000 Plus is the other true 5kWh-class unit. Jackery lists it at 5,040Wh, 7,200W, and 120/240V. We don't track it, and its other specs vary across Jackery's own pages, so it isn't in the table. Check its spec sheet directly if it's on your list.
What each one actually runs
Runtime = usable Wh ÷ device watts, with the device draw used as-is. Nights are rounded down to the half night.
| Load | Typical draw | S5000 (~4,270Wh) | Delta Pro 3 (~3,480Wh) | F3000 (~2,610Wh) | Apex 300 (~2,350Wh) |
|---|---|---|---|---|---|
| CPAP, humidifier on | 60W | ~71 hours (8.5 nights at 8 hrs) | ~58 hours (7 nights) | ~43 hours (5 nights) | ~39 hours (4.5 nights) |
| Full-size fridge (cycling) | ~65W avg | ~65 hours | ~53 hours | ~40 hours | ~36 hours |
| Outage essentials (fridge, Wi-Fi, lights) | ~200W | ~21 hours | ~17 hours | ~13 hours | ~11 hours |
| Window AC unit | ~1,200W | ~3.5 hours | ~3 hours | ~2 hours | ~2 hours |
Our fridge estimate (~65 hours) lands below Anker's 86-hour claim. That's expected: Anker's figure is a specific 700L fridge in a 77°F lab room, and our row assumes a typical cycling draw. On a 200W essentials load, the S5000 carries about four more hours than the Delta Pro 3, roughly one more evening.
Recharge: the 99-minute asterisk
Anker advertises 0–100% in 99 minutes. That figure needs Anker's 4,500W input, which runs on a 240V source. On a regular 120V outlet, the S5000's AC input tops out at 1,800W; Anker's footnote puts that charge at under 3 hours when the draw exceeds 12A. The arithmetic floor:
Hours to full = rated Wh ÷ input watts → 5,024Wh ÷ 1,800W ≈ 2 hours 47 minutes on 120V.
That's the same caveat we score on the F3000 and Apex 300: the advertised fast charge isn't what most people get from a standard outlet. If you have a 240V circuit (or a generator with a 240V outlet), the 99-minute figure becomes reachable.
On solar, the S5000 takes up to 3,000W across two inputs: 1,000W on the low-voltage input (11–60V) and 2,000W on the high-voltage input (16–165V). At our planning multiplier, real solar watts = rated panel watts × 0.65, an array sized to each unit's maximum gives:
- S5000: 5,024Wh ÷ (3,000W × 0.65) ≈ 2.6 hours of full sun
- Delta Pro 3: 4,096Wh ÷ (2,600W × 0.65) ≈ 2.4 hours
- Apex 300: 2,764Wh ÷ (2,400W × 0.65) ≈ 1.8 hours
- F3000: 3,072Wh ÷ (1,200W × 0.65) ≈ 3.9 hours
Filling the S5000's full 3,000W takes two separate arrays wired to its two inputs. Why panels rarely hit their rating is covered in Why Your Solar Generator Charges Slower Than Advertised. Model your own setup in the solar recharge calculator.
240V and the ports that matter
All but the F3000 deliver 240V, which is what runs a well pump, an electric water heater, or a dryer through a transfer switch. The S5000 exposes it directly with a 30A L14-30R outlet, alongside a TT-30R (RV) outlet and 120V 5-20R outlets. Anker also lists 4,500W of bypass power for loads running on wall power through the unit. Whether your house can use 240V from it depends on your transfer switch or inlet, not the station. More on why surge headroom matters for pumps and compressors in Surge Watts vs Running Watts.
As a UPS
Anker states ≤10ms switchover for the S5000, matching EcoFlow's 10ms for the Delta Pro 3. Both sit inside the 16–20ms most desktop power supplies can bridge. The F3000 is rated 20ms; Bluetti states "0ms or 20ms" depending on the outlet. All are manufacturer claims with no stated load, so test with your own hardware before trusting a desktop or NAS to any of them. The full model table is in Can a Power Station Replace a UPS?
What we can't tell you yet
- Real-world efficiency. Anker claims 96% at 1,000W output from internal testing. We use 0.85 for every station until there's independent data.
- Expansion battery prices. Anker hasn't published them, so the true cost of reaching 10kWh or 30kWh is unknown.
- How long the launch price lasts. Anker's launch bonus runs through November 9, but it hasn't said how long the $2,499.99 price holds or where street price settles against the $3,599.99 list.
- Comparative size claims. Anker calls it the smallest, lightest, and longest-lasting 5kWh unit based on its own comparison against unnamed models. We can't verify that, so we haven't repeated it.
FAQ
How long will the Anker SOLIX S5000 run a refrigerator?
About 65 hours for a full-size fridge averaging 65W, using our usable-capacity math (5,024Wh × 0.85 ÷ 65W). Anker's own lab figure is up to 86 hours on a 700L fridge in a 77°F room.
Does the S5000 really recharge in 99 minutes?
Only on Anker's 4,500W input, which needs a 240V source. On a standard 120V outlet the input tops out at 1,800W, which puts a full charge near 2 hours 47 minutes. Anker's footnote says under 3 hours.
Is 10,000 cycles the real battery life?
It's 10,000 cycles to 60% capacity. The comparable figure is 6,000 cycles to 80%, which Anker also publishes. That matches the longest cycle rating among the stations we list.
Can the S5000 run 240V appliances?
Yes. It has 120/240V output and a 30A L14-30R outlet, so it can feed a 240V well pump or water heater through a compatible transfer switch or inlet.
Should I wait for reviews or buy at the launch price?
Anker's launch bonus runs through November 9; it hasn't said how long the $2,499.99 price lasts. If you buy early, confirm the return period with the retailer, since no independent measurements exist yet. If you can't use 240V or don't need 5kWh, the stations below cost less and are already reviewed.
Who should buy what
Best for the most capacity in one box: Anker SOLIX S5000. 5,024Wh, 4,500W at 120/240V, a 6,000-cycle-to-80% LiFePO4 pack, and 3,000W of solar in 97 lbs. The case is strongest at $2,499.99. Don't buy it if you only have 120V wall power and need fast recharge, or you want a unit with independent reviews before you buy.
Best for the biggest expansion path: EcoFlow Delta Pro 3 (currently $2799.00 · see on Amazon). 4,096Wh, a 48kWh ceiling, a 10ms switchover, and 240V output, available and reviewed now. Don't buy it if you'll move it; 113.5 lbs is an installed unit.
Best for 120V essentials: Anker SOLIX F3000 (currently $1398.98 · see on Amazon). 3,072Wh, a 6,000W surge for 120V pumps and compressors, and the lightest unit here. Don't buy it if you need any 240V appliance.
Best for battery longevity at lower capacity: Bluetti Apex 300 (currently $1699.00 · see on Amazon). 2,764Wh, 120/240V, 2,400W of solar, and a 6,000-cycle rating. Don't buy it if you need more than about 11 hours of essentials from a single box.
