Anker is best known for phone chargers and power banks, and its SOLIX line extends that into portable power stations and folding solar panels for camping, RVs and home backup. The Anker SOLIX PS400 is the brand’s 400 watt folding panel. A 400W rating means the panel can produce up to 400 watts in ideal, direct sunlight; in daily use, clouds, angle and heat bring that number down, so think of it as a ceiling rather than a promise.
This guide centers on the genuine Anker SOLIX PS400 Bifacial panel and compares it with three clearly labeled non-Anker folding panels from MHPOWOS, E-POWO and ZOUPW, which differ in weight, whether they collect light from both sides and how high a voltage they produce, so you can see whether the Anker panel is the right fit or an alternative suits your power station better.

Anker SOLIX PS400 Bifacial Portable Solar
Best for: Anker owners wanting the lightest 400W
Pros
- Genuine Anker SOLIX panel
- About 22 lb with stand
- Bifacial, up to 10% more power
- IP68 and 5-year warranty
Cons
- Listing gives no voltage figures
- Bifacial gain needs reflective ground
The Anker SOLIX PS400 Bifacial Portable Solar Panel (model AS340) is the genuine Anker option and the reason most people search for an Anker 400 watt solar panel. Its headline is weight: Anker says it is 10% lighter than the previous version, at just 22 lb including the stand, and over 50% lighter than typical 400W panels. The specs list 21.9 pounds.
“Bifacial” means the panel has solar cells that catch light on both faces. The front takes direct sun, and the back collects light reflected off the ground. Anker says this adds up to 10% more power over reflective surfaces such as snow, sand or concrete; over dark grass, expect less of a boost. The panel uses N-type cells, a newer cell type that Anker says loses less energy and performs better in heat, with 25%+ conversion efficiency, meaning a quarter or more of the sunlight hitting it becomes electricity.
Durability details are strong: a reinforced aluminium frame, impact-resistant materials, an IP68 rating against water and dust, a stated 10-year lifespan and a 5-year warranty. In the box you get two 8.2 ft solar charging cables, a 1.6 ft XT-60i cable, a quick start guide and a safety card. The listing does not specify open-circuit voltage or current, so check your power station’s input range before buying.
It suits Anker SOLIX owners and anyone who carries a panel to campsites often, where every pound counts. It also makes a thoughtful gift for someone who already owns an Anker power station and keeps asking how to charge it off the grid. For smaller Anker setups, our Anker 200W solar panel guide covers the lighter option.
MHPOWOS 400W Portable Solar Panel Foldable Solar Charger as a Non-Anker Alternative
Mhpowos
MHPOWOS 400W Portable Solar Panel Foldable Solar Charger for Power Station
Price and specifications are read from the Amazon product page and can change.
400W Portable Solar Panel Foldable Solar
Best for: Owners of mixed power stations
Pros
- Seven connector types listed
- 5% efficiency
- Four kickstands and pouch
Cons
- Third-party, not made by Anker
- Heaviest 400W here at 27.9 lb
The 400W Portable Solar Panel Foldable Solar Charger for Power Station is made by MHPOWOS, not Anker. Its selling point is connector choice: it lists solar connector adapters for Anderson, XT60, DC7909, DC5521, DC8020, DC5525 and DC35135 plugs, which covers many power stations.
It uses A+ monocrystalline cells with 23.5% efficiency, a 31V maximum voltage and a 12A current rating. It is IP67 waterproof and dustproof, has four built-in kickstands and a zippered accessory pouch, and folds to 37 x 23 x 2.75 inches. At 27.9 pounds, it is about six pounds heavier than the Anker. The listing sensibly warns that a power station’s input limit may cap charging below 400W, which is true of every panel here. It is a single-sided panel, so it does not gain anything from reflected light.
It suits someone with several power stations from different makers who wants one panel with many plugs. If weight is a priority, the Anker PS400 is noticeably lighter.
E-POWO 400W Bifacial Portable Solar Panel as a Non-Anker Bifacial Option
E-Powo
400W Bifacial Portable Solar Panel for Power Station, 25.5% High Efficiency
Price and specifications are read from the Amazon product page and can change.
400W Bifacial Portable Solar Panel
Best for: Snow, sand or white-roof setups
Pros
- Bifacial design
- IP68 with ETFE coating
- 7-in-1 cable
- 18-month warranty
Cons
- Third-party, not made by Anker
- Efficiency listed as 23.5% and 25.5%
The 400W Bifacial Portable Solar Panel for Power Station is made by E-POWO, not Anker. Like the PS400, it is bifacial, collecting direct light on the front and reflected light from snow, sand or white roofs on the back.
The efficiency figures conflict: the title says 25.5%, while the features say up to 23.5% with A+ monocrystalline cells, and the listing highlight mentions 16BB N-type cells. It has an IP68 rating, ETFE coating, a waterproof fabric casing, a 33.6V output voltage, three kickstands and a built-in accessory pouch. It weighs 24.2 lbs and folds to 26.7 x 34.6 x 2.7 inches. A 7-in-1 cable covers DC8020, DC7909, DC35135, XT-60 and Anderson connectors, and E-POWO offers an 18-month warranty.
This fits buyers who like the bifacial idea but want broader connector options than the Anker cables. The Anker offers a longer warranty and a lighter build.
ZOUPW 450W Portable Solar Panel N-Type for Large Power Stations
Zoupw
ZOUPW 450W Portable Solar Panel N-Type 16BB for Power Station
Price and specifications are read from the Amazon product page and can change.
ZOUPW 450W Portable Solar Panel N-Type
Best for: Large high-voltage power stations
Pros
- 450W rating
- 36-month warranty
- Ground stakes and bag included
- IP68 with bypass diodes
Cons
- Third-party, not made by Anker
- 9V Voc suits large stations only
The ZOUPW 450W Portable Solar Panel N-Type 16BB is made by ZOUPW, not Anker. It is rated at 450W and uses N-type monocrystalline cells with 16 busbars (the thin metal strips that collect current), which ZOUPW says reduces resistance and micro-crack risk, with 25% efficiency.
Its open-circuit voltage (Voc) is 45.9V, and ZOUPW says it is designed only for large power stations with a 40-60V input range. It names the Anker SOLIX C1000, C1000 Gen2 and C2000 among compatible stations and warns that it is not compatible with others outside that range. It weighs 29.5 lbs, uses a fiberglass structure, has four kickstands adjustable to 45°, an IP68 rating and bypass diodes that help it keep producing when partly shaded. The kit includes a 4-in-1 adapter cable, four ground stakes and a storage bag, with a 36-month warranty and a 30-day money-back guarantee. ZOUPW also advises against long-term fixed installs or linking it with older panels.
It suits owners of big, high-voltage stations who want every available watt. For smaller stations, its voltage may be too high. See our Anker generator with solar panels guide for matched bundles.
How to Choose the Right 400W Solar Panel
Check your power station’s solar input first. Look up its maximum watts and its voltage range. A panel above that range may not charge at all, and one below the watt limit will simply charge more slowly. The ZOUPW’s 45.9V output is the clearest example of a panel meant for large stations only.
Think about weight. If you carry the panel from car to campsite, the Anker PS400 at about 22 lb is the lightest here, while the ZOUPW and MHPOWOS approach 28-30 lb.
Consider bifacial panels if you camp on sand, snow or light concrete. Both the Anker and E-POWO are bifacial; over grass or dirt, the rear side adds little.
Look at the folded size and setup. Every panel here folds and stands on kickstands, but the folded footprints differ, from about 23 inches wide on the MHPOWOS to nearly 35 inches on the ZOUPW, which affects how easily it fits behind a car seat.
Match connectors and warranty. Anker includes its own cables, while the alternatives bundle multi-connector cables. Warranties range from 18 months to 5 years. If you are still deciding on panel size, our 100 watt solar panel kit review covers small setups.
FAQ
Is the Anker SOLIX PS400 bifacial?
Yes. The listing says it generates power from both front and rear surfaces, adding up to 10% more power over reflective ground.
How much does the Anker PS400 weigh?
About 22 lb including the stand, per the features; the specs list 21.9 pounds.
Are the other panels made by Anker?
No. The MHPOWOS, E-POWO and ZOUPW panels are third-party alternatives from different makers.
Will a 400W panel charge my power station at 400W?
Only if your station accepts that much input and the sun is ideal. Most real-world output is lower, often noticeably so in winter or when the panel is not angled toward the sun.
Which panel has the longest warranty?
The Anker PS400, with a 5-year warranty and a stated 10-year lifespan.
Is a 450W panel better than 400W?
It can deliver more power, but the ZOUPW is designed only for large stations with 40-60V input, so it is not a universal upgrade.
