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.

What the 535 PowerHouse actually runs
The load profiles every comparison on the site is scored on, computed for this unit alone: energy needed against the usable tank after inverter losses, and whether the inverter holds and starts the biggest single load.

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 9 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 want a box with nothing to set up. Four AC outlets, three USB-A, a USB-C, a car socket [A2], and no app to pair.
Decided 4 matchups · read one →
Buy the 535 if your loads are laptop-and-phone small and you carry the unit. At 16.7 lb it rides in one hand to a campsite or a desk, and its usable reserve covers a work session, a night of devices, or a CPAP with room left over.
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 want a stated noise figure and surge rating rather than gaps in the spec sheet, especially for CPAP or bedroom use.
Decided 4 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 →
The buyer who genuinely wants phone-app monitoring, one-hour Turbo charging [B2], or 200W solar for faster off-grid top-ups, and will actually use them.

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.

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.

From the test desk
“Take the RIVER 2 Max.”
“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…”
“Take the SOLIX C800 Plus if anything you own draws more than 500W continuous, a real space heater, a full-size coffee maker, a hair dryer, because the 535's inverter simply won't start it, while the C800 Plus runs up to…”

Questions people ask
Are the EcoFlow RIVER 2 Max and Anker 535 PowerHouse basically the same unit?
On price and capacity, yes — both are $299 for 512Wh at 500W output on 3,000-cycle LiFePO4 cells with a 5-year warranty. The difference is in the specs that don't make the front of the box: the RIVER 2 Max has a published 1,000W surge rating, a 30ms UPS-grade switchover, a faster 220W solar input, and a 100W USB-C port, while the Anker publishes none of those at that level.
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.
Does the 535 PowerHouse have an app?
No. The 535 has no companion app at all; everything is read and set on the unit's own display. The SOLIX C800 added phone-app monitoring and control, one of the clearest upgrades between the two generations.
Is the Anker SOLIX C800 Plus just a bigger 535 PowerHouse?
Not really. It has 256Wh more capacity, but the bigger differences are a UPS switchover, an Anker app, faster solar input, and more than double the continuous output (1200W against 500W), capabilities the 535 was never built with, not just a larger battery.
Does the 535 PowerHouse have UPS protection or app control?
No, both are C800 Plus features. It switches to battery in 20 milliseconds if the wall power drops and pairs with Anker's app for remote monitoring, functionality the 535 shipped without. If either matters to you, the C800 Plus's higher price is buying real capability, not just a bigger battery.
