ALLWEI 400W Solar Panel Review

A 400W solar panel listed from $429 for one panel, or $839 for two, and named for PPS1200 and PPS2400 stations. Its page carries a battery's spec block, so no panel voltage, current, size or weight is available.

Our verdict

Suits a buyer who wants a 400W panel for a PPS1200 or PPS2400 and will confirm voltage, connector and size with the store first. Look elsewhere if you need those figures on the page, since it gives none. The main caveat is that the spec block describes a battery and the FAQ mixes in 100W and 20ow panels.

Why 3.3/5: Lifted only by the 400W name, two priced options and a stated fit with the 1200W/2000W stations. Held back because the spec block belongs to a battery, the FAQ mixes in other wattages and no independent test of this exact panel was found.

Listed from $429 for one panel, the 400W Solar Panel is named for the PPS1200 and PPS2400 stations, and a two-panel option is $839. The page's FAQ says it can charge the 1200W/2000W power stations. Its Tech Specs block, however, describes a LiFePO4 battery rather than a panel, so the page gives no panel voltage, current, efficiency, size or weight.

Options and pricing

Two options are listed: 1 solar panel (400W) at $429 and 2 solar panels (400W) at $839, both in stock when read. The store shows a crossed-out regular price of $649.00 beside the $429 price with a 'Save $220.00' label; that figure is the store's own comparison, not a market price. The page does not list what comes with each option.

How it compares

For the PPS300 and PPS600 stations, the XY-100 100W solar panel lists at $159, against from $429 here for the 400W panel. The ALLWEI PPS2400 Portable Power Station, one of the stations this panel is named for, is from $879, and the Car Charging Cable for PPS1200/PPS2400 at $29.99 is a separate listing for the same two station names.

Shipping, returns and warranty

Shipping: free ground shipping within the contiguous US, not to Alaska, Hawaii, Puerto Rico or the US Virgin Islands. Orders usually ship in 1 to 2 business days and arrive in 3 to 7 business days; the lithium batteries rule out air shipping, so the store uses ground carriers (mostly FedEx), and no signature is required on delivery. It does not ship to P.O. box, APO, FPO or DPO addresses, cannot change an address after ordering, may send a multi-item order in separate packages from different warehouses, and may hold or cancel an order its system flags as risky if the buyer does not answer its verification requests. Returns: an order can be cancelled for free before it ships, and for a full refund within 24 hours of ordering; after shipment the refund policy deducts round-trip shipping and a 2.6% fee for card payments or 3.6% for PayPal, while the shipping policy says a shipped order must be received and then returned, and the warranty page mentions an intercept fee. A 30-day return needs an unused, undamaged product in its original packaging with every accessory, proof of purchase and an RMA number from [email protected]; the buyer pays return shipping unless it is a quality issue, and the refund comes within 14 business days after inspection. A separate 90-day exchange-only policy offers a Class A replacement for the PPS300, PPS600, PPS1200, PPS2400 and B200 Pro. Warranty: the warranty page names the PPS2400, PPS1200, B200 Pro, PPS600, PPS300, XY-200, XY-100 and CH-100 and accessories bought separately, but not this product, so ask support which period applies before buying. The warranty applies to purchases through official channels with proof of purchase; unauthorized modification, bad storage, corrosion, incompatible accessories, force majeure, misuse and an expired period void it, and for repairs that need shipping the policy puts the shipping cost on the customer after the store verifies the product's condition. Payment: cards, PayPal, Apple Pay, Google Pay and Shop Pay, with Affirm or Klarna installments on items over $500.

Before you buy

The store shows a crossed-out regular price and a 'Save' amount on its product pages; these are its own comparison figures, not market prices, and some pages add promo banners (such as 'Black Friday Offer $100' or 'Apply Extra $20.00 Coupon') without saying whether the displayed price already includes them. Some pages state certifications (UL2743, UN38.3 and FCC on the PPS2400 page, ETL UL458 on the 3000W inverter page) and '200+ patents'; those are the store's own statements and we found no certificate numbers or listings. The About page says ALLWEI is a brand of ALLWEI Trading Inc., founded in 2012, with the ALLWEI brand launched in 2015; the allweipower.com domain was registered on 29 August 2024, the terms list an address in Rialto, California, and the contact page names a Hong Kong company (HK Bridna Technology Co., Limited). The pages promise support 24/7, while the policy pages give phone hours of Monday to Friday, 9 AM to 5 PM PST. Trustpilot shows one review for allweipower.com (5 stars, March 2026) on an unclaimed profile, and we found no independent lab test of any ALLWEI product.

What we liked

  • The page states a 400W rating and prices one panel at $429 and two at $839.
  • The FAQ says it can charge the 1200W/2000W power stations, and the title names PPS1200 and PPS2400.
  • The page photos show a four-section foldable panel, and both options were in stock when read.

Worth noting

  • The Tech Specs block belongs to another product (a LiFePO4 battery), so the page has no panel voltage, current, efficiency, size or weight.
  • The FAQ's 1200W/2000W stations do not match the title's PPS1200 and PPS2400, and it also mentions a 100W panel and a '20ow' panel.
  • No connector type, cable or box contents are given for the 400W panel or for the two-panel option.

Questions before you buy

Which power stations does the page say the 400W panel charges?

The FAQ says it can charge the 1200W/2000W power stations, and the store title names PPS1200 and PPS2400. For third-party devices, the FAQ tells buyers to contact customer service to confirm compatibility.

What do the two options contain?

The options are 1 solar panel at $429 and 2 solar panels at $839, both in stock when read. The page does not list a cable, a connector or a weight for either option.

Why does the page show battery figures?

Its Tech Specs block describes a LiFePO4 battery, not a solar panel. This review does not use those figures for the panel; the page gives no panel voltage, current, efficiency, size or weight.

Does ALLWEI ship outside the contiguous US?

The shipping policy covers free ground shipping within the contiguous US only, not Alaska, Hawaii, Puerto Rico or the US Virgin Islands. It ships by ground because of the lithium batteries, usually in 1 to 2 business days, with delivery in 3 to 7 business days.

What is the return window?

The return policy gives 30 days from receipt for an unused, undamaged product in its original packaging, with proof of purchase and an RMA number from [email protected]. The buyer pays return shipping unless it is a quality issue, and the refund follows within 14 business days after inspection.

Can I pay in installments?

The payment page lists Affirm and Klarna installments for products priced above $500; eligible customers click Prequalify now on the product page. Other options are cards, PayPal, Apple Pay, Google Pay and Shop Pay.

How long is the warranty?

The warranty page does not name this product, so ask support which period applies before buying.

Independent

What we couldn’t verify

  • PAGE DEFECT: the Tech Specs block lists a LiFePO4 2048Wh battery, not a solar panel, and the page gives no panel voltage, current, efficiency, size or weight; none of the battery's figures are used here.
  • The FAQ discusses a 100W panel with a 5521MM port, a '20ow' panel and the 1200W/2000W stations, so it is unclear which answers apply to the 400W panel; its IP68 water-resistance statement names no wattage.
  • The pages promise support 24/7, while the policy pages give phone hours of Monday to Friday, 9 AM to 5 PM PST.
  • The warranty table labels the extra warranty period 'Paid' while the text describes an extension after registration.
  • No independent lab test of any ALLWEI product was found; Trustpilot shows one review on an unclaimed profile.
