ALLWEI 300W / 256Wh Power Station Review
A 256Wh power station with 300W AC output and a 600W peak, listed from $179 at 6.5 LBS. It suits phones, a laptop or a router during short outages and camping trips, with a 100W solar panel option at $359.

Our verdict
A fit for light loads under 300W, such as phones, a laptop or a router, on short outages and camping trips. Look elsewhere for anything above 300W or for more than one AC outlet. The main caveat is that the page never names the cell chemistry and gives its weight two ways, 6.4 lbs in the copy and 6.5 LBS in the spec block.
- Best for
- Small loads under 300W, such as phones, a laptop or a router, on short outages and camping trips.
- Skip if
- You need more than one AC outlet or any load above 300W.
Why 3.5/5: Lifted by a spec table covering capacity, output, ports, charging times, weight and size. Held back by figures that disagree on the page and because no independent test of this exact unit was found.
A 256Wh battery and a 300W AC outlet make up this compact ALLWEI station, which the page lists from $179. The spec block gives a 600W peak, pure sine wave output, a 6.5 LBS net weight and a 9.25x5x6.8in size, and the copy adds a silent fan and an SOS LED light. It comes alone at $179 or with a 100W solar panel at $359. The copy calls it the PPS300, while the title names no model code.

Options and pricing
Two options are listed: the 300W Power Station alone at $179 and the 300W + 100W Solar Panel option at $359; the page text shows -$50 right after that price without saying whether the $359 already includes it. For the unit alone the store shows a crossed-out regular price of $249, which is its own comparison, not a market price. The page gives no model or specs for the 100W panel; its FAQ only recommends a 100W panel.
How it compares
The ALLWEI PPS600-1 lists from $329 with 500W and 512Wh in its title, against 300W and 256Wh at $179 here. The PPS2400 starts at $879. If a separate panel is wanted, the XY-100 100W Solar Panel is listed at $159 and its title names PPS300 and PPS600 units, while this page's own solar option is $359 with the unit.
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 does not name this 256Wh unit by its title; its copy calls it the PPS300, which the page lists with a 2-year standard warranty from purchase and 1 more year if you register (the table labels that extra year 'Paid'), and the store also sells a separate PPS300 rated 280Wh, so ask support which period applies. 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.

Questions before you buy
How much can the AC outlet run?
The page lists 300W Max continuous and a 600W peak with a pure sine wave output through 1 US AC outlet. Its copy says to stay under 300W, and the spec block gives over-load protection at 340W+/-20W.
How does it recharge and how long does it take?
The page gives AC charging at 3.5 to 4 hours, car charging at 3 to 3.5 hours and a 100W solar panel at 3.5 to 4 hours in full sunlight. Dual charging with an AC wall socket and a 100W panel is listed at 2 to 2.5 hours. The external charger is AC100-240V to 19V 3.0A 57W.
Can it jump-start a car battery?
No. The page says the unit is not suitable for jump-starting a car battery.
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 256Wh unit by its title. Its copy calls it the PPS300, which the page lists with 2 years plus 1 more with registration, and the store also sells a separate 280Wh PPS300, so ask support which period applies.

What we couldn’t verify
- Cell chemistry is not named: the copy says 'quality lithium batteries'. The capacity row pairs 256Wh with 26Ah/10.8V, the same Ah and voltage the store's separate PPS300 page gives for 280Wh.
- AC recharge is given as 3.5 to 4 hours with a 57W external charger; the store's separate 280Wh PPS300 page lists the same charger and 5.5-6.5 hours. Weight is 6.4 lbs in the copy and 6.5 LBS in the spec block.
- The title names no model code but the copy calls the unit the PPS300. The spec block has no solar input row. The page says the AC adapter has UL certification; no certificate was found.
- 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.
