Anker 535 PowerHouse
The 535 PowerHouse belongs to no Anker line, which dates it: before the SOLIX badge existed. Half a kilowatt-hour at seventeen pounds, 3,000 rated cycles, a five-year warranty, a CPAP night and nothing longer. It wins 13 of 33 head-to-heads, all five against Goal Zero. The one owner who wrote in was returning it for a RIVER 2 Pro.

03 · From the verdicts
Who it is for, and when a rival won instead
Each line is lifted from a written matchup where it decided the verdict, and links to the page it came from. Repeated across many matchups means it is the unit’s signature, not one author’s opinion.
Buy the 535 PowerHouse if…
You want the simplest possible box: no app to pair, nothing to expand, plug in and go.
Decided 8 matchups · read one →
You want a lamp, a fan and a CPAP on AC at the same time; the Anker's four AC outlets mean no power strip.
Decided 5 matchups · read one →
The weekend camper whose real draw is phones, lights, a fan, and a laptop, staying inside 435 usable watt-hours. At 16.7 lb it rides along without a second thought.
Decided 5 matchups · read one →
You run a CPAP overnight off battery. The 535 finishes the night with room to spare; the C300X taps out before morning.
Decided 3 matchups · read one →
A rival won when…
You want the bigger tank and faster refill: 960Wh and 500W of solar input against the 535's 512Wh and 120W.
Decided 6 matchups · read one →
You carry it more than you drain it. The 9.1-lb C300 slips into a daypack and disappears; the 16.7-lb 535 you feel on your shoulder.
Decided 3 matchups · read one →
You want a stated noise figure and surge rating rather than gaps in the spec sheet, especially for CPAP or bedroom use.

How to read this
- Usual is the price the unit carried most of the time, tested for how long it held rather than how often we looked. A weekend promotion cannot move it.
- Best is the lowest price we have read on the store itself. Typed coupon codes, member-only prices and marketplace listings are not counted; anything applied automatically at checkout is.
- A gap in the line is a day we could not read a price. We never draw across one, and we never show the store’s own “was” price.

Will the Anker 535 PowerHouse go on sale for Black Friday?
Price to beat $300Nobody knows until Anker SOLIX moves, but in 80 days we have tracked it, it has never been discounted, so any real cut would be a first. Last Black Friday it was reported at $249 at Anker SOLIX store. We read the store twice a day, and the moment it drops it shows on our Black Friday deals page.

Raw counts reward whoever writes most, and people write when something breaks. Here each report is weighted by what the complaint costs a buyer (a failure outranks an app gripe) and by its evidence (a measured owner report outranks a shopper’s opinion), then compared with every report in the corpus.

“Buy the Anker 535 PowerHouse.”
“The SOLIX C800 is the more complete unit: 768Wh against the 535's 512Wh (256Wh more), 1200W continuous with a 1600W surge rating against 500W with no surge spec listed, a 20-millisecond transfer switch, phone-app…”
“Buy the 535 PowerHouse unless portability or the modern feature set is the whole point.”

Questions people ask
Is the Anker 535 PowerHouse as good as the RIVER 2 Max?
On capacity, output, cycle rating, warranty and outlet count, yes: both are 512Wh, 500W continuous, 3,000 cycles, 5 years, four AC outlets. The Anker gives up the RIVER 2 Max's UPS mode, its app, its faster 220W solar input (the Anker takes 120W), its 100W USB-C (the Anker's is 60W) and a published surge rating. If you charge from a wall and don't need those, the Anker does the same job.
Can the Anker 535 PowerHouse run a CPAP all night?
Yes, with room left over. A CPAP at about 40W for eight hours uses 320Wh, which is 74% of the 435Wh the 535 has usable after the page's 85% derate, leaving 115Wh. Anker doesn't publish a noise figure, so give it a night at the bedside before you rely on it.
Does the Anker 535 PowerHouse work as a UPS?
Not by its spec sheet, which lists no UPS mode and no switchover time. The RIVER 2 Max lists one, rated no worse than 30ms, quick enough for a router and long enough that many desktop PCs reboot anyway. With the Anker, plan to move plugs over yourself when the grid drops.
How long does the Anker 535 PowerHouse take to charge from solar?
About 4.3 hours at its full 120W rating, and that's the floor. One review found it realistically took in 60-75W [B4], which stretches a full 512Wh refill to roughly 7 to 8.5 hours. Treat solar as a top-up and the wall as the main charger.
Is the Anker SOLIX C800 just a bigger version of the 535 PowerHouse?
Not really. It does hold more — 768Wh against 512Wh, 256Wh more — but the bigger changes are a 20-millisecond transfer switch for UPS-style backup, phone-app control, and solar input up to 300W against the 535's 120W ceiling. None of those existed on the 535 at any capacity.
