ALLWEI 2000W Pure Sine Wave Inverter Review

Rated for 2000W continuous with a 4000W peak surge, the ALLWEI 2000W inverter converts 12V DC to 110V/120V AC and is listed at $169 as a single variant. The page adds an LCD, an efficiency figure of over 91% and a 10-foot cable for remote operation, and says the unit suits 12V battery banks only. Unlike the 1000W and 3000W pages, it states no weight or operating temperature range.

Specifications

Options and pricing

One variant is listed at $169 and was in stock when the page was read. The store shows a crossed-out regular price of $259 beside it, which is its own comparison, not a market price. The page says the unit comes with a 10-foot cable for remote operation and names no other contents, such as battery cables.

How it compares

The ALLWEI 1000 Watt Pure Sine Wave Inverter lists at $109 and the ALLWEI 3000 Watt Pure Sine Wave Inverter at $199, so this 2000W unit at $169 sits between them in price; all three titles carry the 12V to 120V AC wording. The ALLWEI PPS2400 Portable Power Station is a power station listed from $879 with 2048Wh and 2400W in its name, a different product from an inverter that runs off a separate 12V battery bank.

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.
