PeakLoadout finding
Of 32 portable power station listings from 4 makers read on 20 October 2026, 4 name a safety standard (all Goal Zero), 9 call the unit a UPS without naming UL 1778, and 5 of 23 cycle ratings state the test conditions behind them.
What does a power station listing tell you about its battery?
Less than the battery needs. A listing almost always gives the watt-hours and the price. It rarely gives the facts that decide how long those watt-hours last and how safely they are stored: the cycle rating with the conditions it was measured under, a named safety standard, and, for a unit sold as backup power, how fast it switches over.
We read the listing text each maker publishes for 32 base units (no bundles, expansion kits or regional editions) and recorded which of 7 facts it states. This is the same text a store sends to shopping engines and AI shopping agents, so it is what those systems can repeat.
Why does a cycle rating need its test conditions?
Because the number moves with them. A cell rated to 70% remaining capacity reports more cycles than the same cell rated to 80%; a rating taken at 25 °C and a gentle charge rate reports more than one taken hot and fast. 23 of 32 listings state a cycle count; 5 state all three conditions, all from Goal Zero. EcoFlow states no cycle count in any of its 7 listings.
What does a kilowatt-hour of stored energy cost over the battery's life?
Divide the price by the energy the battery can deliver over its rated life: watt-hours times rated cycles. It is a best case, because it assumes every cycle delivers full nameplate capacity, and it is paid on top of the electricity that charges the unit (US residential average 18.31 cents per kWh, EIA, July 2026).
Which listings name a safety standard?
4 of 32: the Yeti 300, Yeti 500, Yeti 700, Yeti PRO 4000, each naming UL 2743, the standard for portable power packs. 9 listings describe the unit as a UPS; none names UL 1778, the standard for uninterruptible power supplies, and 6 give no transfer time. A missing standard on a listing does not mean the unit is uncertified; it means a buyer reading the listing cannot tell.
What did the listings get wrong?
- Pecron. The F1000LFP is titled 960Wh on Pecron's store, while the product's own web address reads 1004wh. Listing
- Goal Zero. The NEW Yeti 1000 (998Wh) product page also carries the Yeti 1500's 1,505.28Wh figure. Listing
For makers: if a listing here has changed, or a figure is stated somewhere we did not count, send the link through contact and corrections and we will re-read it and date the change.

Are the sale prices real sales?
On 20 October 2026, 22 of 32 units were listed below a compare-at price, from EcoFlow, Jackery, Pecron. The median listed reduction by maker: EcoFlow 17%, Jackery 10%, Goal Zero 0%, Pecron 48%. A compare-at price is the maker's own claim about a former or usual price. Whether a sale is a sale depends on how long that price has stood, so the per-unit verdict appears here after four weekly reads; 1 has been taken.
Method
Units. Base portable power stations sold on each maker's own US store, joined by product handle to the weekly catalog read. Bundles with panels, expansion batteries, charity and regional editions are excluded. Capacity is the maker's figure from the listing title, the listing text, or the maker's spec page; a unit with no unambiguous capacity is left out.
Listing text. The product description each store publishes (the Shopify product feed), read 20 October 2026 and coded by hand. Specs shown only in a separate spec tab, an image or a PDF are not counted. Excerpts for every coded field are kept with the dataset.
Prices. The lowest variant price and its compare-at price on each read, from the network's price poller, which reads every store's public catalog each Monday.
Score. One point each for chemistry, a cycle count, each of the three cycle test conditions, a named safety standard, a transfer time, and a warranty term (maximum 7).
Limits
This measures listings, not batteries: a unit can be certified, or have a full spec sheet elsewhere on the maker's site, and still score low here. The lifetime cost is a best case from the maker's own rating, not a test. Four makers are covered; Bluetti, Anker SOLIX and DJI do not publish a readable catalog feed and are not in this edition.

FAQ
What does a power station cycle rating actually mean?
A cycle rating is the number of full charge and discharge cycles before the battery falls to a stated share of its original capacity. Without that share (usually 70% or 80%), the temperature and the charge rate, two ratings cannot be compared. Of 23 listings here that state a cycle count, 5 state all three conditions.
Which safety standard should a portable power station list?
UL 2743 covers portable power packs; larger fixed energy storage systems fall under UL 9540, and a product sold as a UPS is covered by UL 1778. On 20 October 2026, 4 of 32 listings named any of them, all from Goal Zero.
Is a power station with a UPS claim a real UPS?
A UPS claim describes how fast the unit switches to battery when the grid drops. 9 listings here use the word; none names UL 1778, the UPS safety standard, and 6 of them give no switchover time at all.
What is the cheapest power station per kWh of battery life?
On a best-case reading (full nameplate capacity on every rated cycle), the lowest here is the Jackery HomePower 3600 Plus at 7.95 cents per kWh. The cheapest figures come from cycle ratings that state the fewest test conditions, so they are the least comparable.
How often is this data updated?
Prices are read from each maker's own US store every Monday by the Lattice price poller, and this page is rebuilt from each read. The listing disclosure was read on 20 October 2026 and is re-read when a listing changes. Next price read: 26 October 2026.
