Anker SOLIX PS400: twice the glass, honestly weighed
The sticker says 400 watts, double the other folders here. The handle says 35.3 pounds, which is the number that actually decides this purchase. Buy it for an Anker station whose input can drink 400 watts, and buy it for somebody who means to carry it. That somebody might genuinely be you. This review helps you find out before the checkout does.
The short version
- The Anker SOLIX PS400 is the 400-watt folding panel in our catalog, and the figure that decides the purchase is 35.3 pounds, not the wattage.
- Sealing is a printed IP67 and the price was $699.99 on August 26, 2026; the open-circuit voltage is a dash, because Anker's pages never agree on one.
- The review weighs both numbers against your station's solar input and the carry you'll actually make.

Anker SOLIX PS400
Twice the daylight of a 200-watt folder, if you are honest about carrying 35 pounds to the driveway.
$699.99
Price checked Aug 26, 2026
Two figures run this review, and they pull in opposite directions: 400 watts of nameplate daylight, and 35.3 pounds of packed reality. The rest, as Anker lists it on August 26, 2026: sealed to IP67, $699.99 with no strikethrough beside it. It’s the big folder of our three. Not a roof, not a briefcase, and not quite the same kind of “portable” as a 14-pound SolarSaga, whatever the shared adjective suggests.
Lovely fit if
- You’re an Anker home, running the C2000 Gen 2 or the F3800, and you’ll confirm the station’s solar window first, the way the label asks.
- You’ve walked the real route to the driveway with 35 pounds in mind and made peace with it, not once in a product video but as a habit.
- A 200-watt folder genuinely undershoots your daylight needs, and you know 400 still bows to haze.
- You want a sealing rating quoted from the maker: IP67, in writing.
Better served elsewhere if
- 35.3 pounds is a no, and it’s allowed to be a no. A 200-watt folder, or just more watt-hours, will serve you better than a trophy leaning in the garage.
- Your station’s solar input tops out well under 400 watts. Past that ceiling, the extra glass is just exercise.
- Your station is a Jackery or a BLUETTI. The SolarSaga or the SP200L keeps the cables matched.
- Your outages are short and after sunset, when every panel on earth produces the same zero.
400 watts versus real sun, and 35.3 pounds
On paper this is twice the SolarSaga. In a driveway, the multiplier is weather. Aim it well under good June sun and the midday intake genuinely outruns any 200-watt folio. That’s the happy case, and it’s real. Winter haze pays a fraction, and the 35.3-pound carry costs exactly the same either way. Not a complaint, just the shape of the purchase: you buy the good days at full price, and the gray ones come bundled.
The weight deserves its own honest paragraph. It’s 21 pounds more than the SolarSaga and 18 more than the SP200L. A two-hand carry that stairs will lengthen and gusts will test, because those kickstands are bracing a bigger sail. The telling detail: when the wind does win, 35.3 pounds is both the ballast that resisted and the object now sliding across your driveway, so supervision isn’t optional equipment. IP67 covers water and dust, as printed. Hail and theft remain, as ever, your department.
Price that day: $699.99. See tonight’s price at Anker →. Same price to you either way, disclosure here.
- Read the solar window on the station you actually own. The C2000 Gen 2 and the F3800 each list their own maximum watts and voltage.
- Walk the closet-to-driveway route with 35.3 pounds in your head. If the route says no, believe it and buy lighter.
- Don’t invent a voltage to justify series cables. The dash in our table is there because Anker never prints one.
- Aim, supervise, fold. A big folio is simply more panel to rescue when a gust wins.
The voltage we won’t guess
The PS400’s open-circuit voltage is a dash in our tables. Anker’s pages never settle on one figure, the same trouble Jackery has with the SolarSaga. (The SP200L is the folder in this category whose maker writes it down: 24.6 V.) Let’s be precise about what a dash is not. It is not “probably around 40.” It’s an instruction: read the live page, and if you still can’t find a number you trust, don’t series-wire. Full stop. Cold, bright mornings push voltage up, and charge-controller maximums are not suggestions.
The watt ceiling is the other half of the homework: if your station’s input clips below 400 watts, some of this glass will simply never be asked to work, and you’ll have paid full price for the idle half. Two minutes with the live page settles it. The complete gentle lecture: the panel buying guide.
The whole review in one line: twice the daylight of the 200-watt folders, for the Anker home that checks its solar window first and carries 35.3 pounds on purpose.
Pairing it with the Anker machines
In-family is the point. The C2000 Gen 2 is the light 120-volt station (2,048 Wh, 2,400 W, 41.7 lb). The F3800 is the split-phase cabinet (3,840 Wh, 6,000 W, 132.3 lb). Both take portable solar. Neither forgives a guessed voltage, and neither one turns this folio into a roof.
Scale the expectation to the tank: the F3800 holds 3,840 Wh, and one PS400 in poor sun won’t refill it by dinner. That isn’t failure. That’s the product working at winter’s pace. More panels mean more 35-pound carries and more voltage arithmetic, and if the honest requirement is multi-day winter runtime with no sun at all, the grown-up comparison is battery vs standby, not a bigger blanket.
- 400 W of daylight · 35.3 lb · IP67 · $699.99 (August 26, 2026).
- Voltage: a dash. Confirm it live, and never series-wire on a guess.
- Made for Anker SOLIX inputs, after you’ve read the watt window.
- Twice the sticker of a 200-watt folder is not twice the January kilowatt-hours.
- If you won’t carry 35.3 pounds, that’s an answer, and a fine one. Buy lighter.
What we’re not claiming
No controlled year of yield logging behind this page. EcoFlow’s 400-watt folders aren’t featured (7-day affiliate window), and there’s still no named briefcase panel here. That format gets an honest discussion at folding vs briefcase. Method: how we review · the shop: Anker SOLIX.
The fit line. If the carry has to stay under 20 pounds, buy a 200-watt folder. If your station’s input clips below 400 watts, keep your money. A Jackery or BLUETTI home should stay in its own family. But for the Anker household with the sun, the station, and the shoulders, this is the big folder, and it delivers.
