Anker SOLIX S5000 Portable Power Station
Certified, documented and already inside Anker’s app. The second S-series power station is ready, and only the reveal remains.
Anker’s next big power station has left the lab. A unit named the Anker SOLIX S5000, model AS510, cleared certification on September 15, 2026. Its user guide is written and staged on Anker’s support system, and the Anker app already carries a product card for it, complete with a drawing of the machine: an upright cabinet on wheels with a full-width control panel. Anker’s naming habits point to a pack of roughly 5 kWh, the S-series playbook points to long, quiet runtime rather than brute output, and the company’s last launch ran five weeks from paperwork to checkout. This page assembles the evidence and our reading of it.

01 · What surfaced
What Anker has already put in writing
First surfaced September 15, 2026 in regulatory filings for model AS510. The framing below is ours; every figure in it is graded in the ledger that follows.
Anker built the S series around endurance. The S2000 pairs a 2,010 Wh pack with a deliberately modest 1,500 W inverter and sells the result as fridge backup measured in days, backed by a 10,000-cycle rating and a five-year warranty. It is the mirror image of the F series, where the F3800 puts 6,000 W and split-phase output behind a similar pack. An S5000 extends that bet: that people buying home backup care more about how long the lights stay on than how much they can run at once.
The size changes the conversation. At roughly 5 kWh the S5000 steps into territory Anker covers today with the F3800 and the E10, both of which deliver 120/240 V split-phase for well pumps and central air. If the S5000 arrives with split-phase, Anker gains a second home-backup line. If it stays single-voltage like the S2000, it becomes the longest-running fridge-and-freezer machine in the range. The wheels in Anker’s own drawing suggest a unit meant to live in a utility room and be rolled to where it is needed.

SOLIX S5000 specifications
Everything known so far, line by line, so you can tell which numbers are firm enough to plan around. Each figure is marked Anker-published or published by us; where we reason beyond the published figures, the reasoning is shown.
The spec sheet at a glance
Our own rendering of the unit: an upright cabinet inside a frame that runs down to its wheels, a louvred intake across the top, a display and control strip, an illuminated power key and a light bar set into the base.
- Our read on timing
- October. Anker’s S2000 cleared certification on April 30, 2026, reached reviewers on May 19 and went on sale June 2: three weeks from paperwork to press, five to checkout. The S5000 cleared the same gate on September 15.

How we knowEstablished by our own checks of Anker’s support system on September 20, 2026.
- Published by us
- Our read on capacity
- Roughly 5 kWh. Anker names every unit for its pack, never its inverter: the C1000 holds 1,056 Wh, the F3800 holds 3,840 Wh, and the S2000 holds 2,010 Wh behind a 1,500 W inverter. On that unbroken pattern, S5000 means a pack of about five kilowatt-hours.
- Our analysis
- Our read on output
- Around 3,600 W. The S2000 pairs 2,010 Wh with 1,500 W, about 0.75 W per watt-hour. Carried to a 5 kWh pack that is roughly 3,700 W, and 3,600 W happens to be the ceiling of a 30 A, 120 V outlet. We think that coincidence is the design.
- Our analysis
- Our read on weight
- Near 90 lb, which explains the wheels. The S2000 weighs 35.7 lb for 2,010 Wh, about 18 lb per kilowatt-hour. A 5 kWh pack at the same density lands around 90 lb, past what a carry handle can fairly ask of anyone.
- Our analysis
- Our read on lifespan
- The S2000 is rated for 10,000 cycles, more than double Anker’s F line, and long life is the whole premise of the S series. We expect the S5000 to carry the same cells and the same claim.
- Our analysis
- Our read on price
- The S2000 listed near $1,200 and opened at $599 for early-access subscribers. The same list ratio puts a 5 kWh S5000 around $3,000, and Anker’s habit of steep launch-day pricing points to an opening offer well below that.

What the published numbers imply
Runtimes worked out from Anker’s own figures. These are our estimates, and they are labelled as our analysis everywhere they appear.
| Load | Base pack · — |
|---|
Assumes 85% of rated capacity reaches the load — the same planning constant our comparison engine uses for every station. Real runtime at 0 W will also depend on how the pack derates in heat, which nobody has measured yet.
Good to knowEvery estimate above updates automatically if Anker revises a published figure; nothing here is typed in by hand.
04 · Our take
What the SOLIX S5000 is really for, and who it is aimed at
Analysis by the Test Desk — not a summary of Anker’s release or anyone else’s coverage. Every comparison figure below comes from the named maker’s own page.
Start with the manual, because it says more than the certification does. A certification tells you a product exists. A finished user guide, staged on the maker’s own support system and waiting to be switched on, tells you the documentation team is done, the model has its permanent home, and the only open item is a date. That is where the S5000 stands today.
The runway is visible too. The S2000 carries separate country editions of its guide, and those are traditionally the last pieces to land before a launch. For the S5000 the master guide is in place and the country editions are the next step. Set that beside the calendar, where the S2000 took five weeks from certification to checkout with reviews at week three, and an October reveal is the natural reading.
Our thesis on the machine itself rests on Anker’s own habits. Every C, F and S unit is named for its pack: 1,056 Wh is a C1000, 3,840 Wh is an F3800, and the S2000 holds 2,010 Wh even though its inverter stops at 1,500 W. That last case is the key, because it proves the number is energy rather than power. So S5000 reads as roughly 5 kWh. Carry the S2000’s ratio of pack to inverter forward and you arrive near 3,600 W, which is also the most a 30 A, 120 V outlet can deliver. We think that coincidence is the design.
The drawing supports the same picture. Anker shows an upright cabinet in a frame that runs down to a pair of wheels, with a louvred intake across the top and a full-width control strip. At the S2000’s energy density a 5 kWh pack weighs close to 90 lb, so the wheels are a necessity rather than a flourish. This is a machine designed to be parked near the appliances it protects and rolled out when the grid drops.
For a shopper the play is simple. Anker launches through an early-access email list that unlocks its best price on day one; the S2000 opened at $599 against a list near $1,200. Joining that list when it opens costs nothing and is the smart way to buy this unit. If your backup needs are urgent, the F3800 delivers 3,840 Wh, 6,000 W and split-phase output today, and hurricane season keeps its own calendar.

Who should wait for it, and who should not
Read from what Anker has already committed to paper.
Worth waiting for if you are
- Anyone already shopping Anker’s home-backup line who can give it a month. The reveal looks close, and Anker’s launch-day pricing has been worth the wait before.
- S2000 owners curious whether the long-runtime idea scales, which is the real question this unit answers.
- Shoppers who want roughly 5 kWh in one box and prefer Anker’s endurance-first approach to the F3800’s big-inverter one.
Buy something that ships if you are
- Facing storm season with thin backup today. The F3800 is on sale now with 3,840 Wh, 6,000 W and split-phase output.
- Backing up a well pump, a range or central air. Anker’s F3800 and E10 are proven 240 V machines, while the S series has so far been a 120 V family.

Yes. The Anker SOLIX S5000, model AS510, cleared certification on September 15, 2026. Its user guide is written and staged on Anker’s support system, and the Anker app already carries a product card for it. The public reveal is the remaining step.
Confirmed so far: the name, model number AS510, Wi-Fi and Bluetooth for app control, and the shape, an upright wheeled cabinet with a full-width control panel. Our grounded estimates are a pack of roughly 5 kWh, an inverter around 3,600 W and a weight near 90 lb, each with its reasoning shown in the spec section above.
Our reading is a pack of roughly 5 kWh. Anker names every unit after its battery rather than its inverter: the S2000 holds 2,010 Wh but outputs 1,500 W, so the number is energy, and S5000 points to about five kilowatt-hours. At the S2000’s density that is a machine of around 90 lb, which is why Anker’s drawing shows wheels.
We expect October 2026. Anker’s last S-series launch ran three weeks from certification to reviews and five weeks to going on sale, and the S5000 cleared certification on September 15. The signals to watch are the country editions of its manual going live and an early-access signup opening on Anker’s site.
That is the reveal we are watching most closely. The S2000 is a 120 V machine, while Anker’s F3800 and E10 both deliver 120/240 V split-phase. A 240 V port on the S5000 would make it a genuine second home-backup line. If you need 240 V today, the F3800 and E10 already do it.
Anker’s Anker SOLIX F3800 is $2,200 today and gives you 3,840 Wh, 6,000 W and 120/240 V split-phase, a known quantity in a season that keeps its own calendar. If what draws you is the S-series endurance rather than the size, the Anker SOLIX S2000 is that machine at $1,000.
