ALLWEI 1000W Pure Sine Wave Inverter Review
A 12V-to-120V pure sine wave inverter rated at 1000W continuous with a 2000W peak surge, listed at $109 and 3.53 lb. It fits 12V battery banks and loads within 1000W, but the page has no spec table, so many details are missing.
Our verdict
Suited to 12V battery banks feeding AC loads that stay within 1000W, at $109 against $169 and $199 for the 2000W and 3000W pages. Look at the 2000W or 3000W pages if you need a higher continuous rating; neither gives a spec table with outlets or terminals either, so look elsewhere if you need one. The main caveat is how little the page states beyond output, weight, operating range and a protections list that ends with 'and more'.
- Best for
- Buyers with a 12V battery bank and AC loads within 1000W who can accept a page with few stated specs.
- Skip if
- You need more than 1000W continuous, a full spec table, or a battery system that is not 12V.
Why 3.4/5: A weight, an operating range, stated continuous and peak output and a clear 12V-only note lift it. A short page with no spec table, and no independent test of this exact model, hold it back.
At 1000W continuous with a 2000W peak surge, this is the 1000W version of ALLWEI's 12V pure sine wave inverter, listed beside 2000W and 3000W versions. The page lists it at $109 as a single variant, with a weight of 3.53 lb and a 14°F-104°F operating range. The input is 12V DC and the output 110V/120V AC, and the page says it suits 12V battery banks only. Beyond a short description there is no spec table.

Options and pricing
There is one variant, listed at $109 and in stock when the page was read. The store also shows a crossed-out regular price of $199, which is its own comparison, not a market price. The page does not list what comes in the box, so battery cables, a remote or other extras are not stated either way.
How it compares
The ALLWEI 2000 Watt Pure Sine Wave Inverter lists at $169 and the ALLWEI 3000 Watt Pure Sine Wave Inverter at $199, against $109 for this 1000W unit. The ALLWEI PPS600-1 Portable Power Station is a different kind of product: a power station listed from $329 with 500W and 512Wh in its name, while this inverter is described as running from a 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.
What we liked
- 1000W continuous and a 2000W peak surge are both stated, with efficiency given as over 91%

- The page describes the pure sine wave output as matching the public grid waveform
- Listed at $109, against $169 and $199 on the 2000W and 3000W inverter pages
Worth noting
- No spec table: outlet count, DC input terminals and current, dimensions and certifications are not given
- The page says 8-fold protection but names only low/high voltage, temperature extremes, overload and short-circuit, then 'and more'
- Limited to 1000W continuous and, per the page, to 12V battery banks only
- The 131°F fan threshold sits above the 104°F top of the operating range, and the page does not say what it measures
Questions before you buy
What output does the ALLWEI 1000W inverter list?
The page lists 1000W continuous power and a 2000W peak surge, with efficiency stated as over 91%. It converts DC 12V to 110V/120V AC, and the page describes the output as pure sine wave and as suited to sensitive devices such as TVs, laptops and refrigerators.
