How WattBunker decides what to recommend.

WattBunker is an editorial site, not a hardware lab. We don't own a battery cycler. We don't run units through six weekends in the Sierras. What we do is read the same things you'd read if you had infinite time — and then write the comparison the Amazon listing won't.

What we actually do

1. Read the manufacturer spec sheet. Capacity, AC output, surge, cycle life, chemistry, dimensions, warranty terms.
2. Cross-check against the Amazon listing. Sometimes they don't match — pricing, ratings, reviews, "bought in past month".
3. Read the verified-buyer reviews. Especially the 1- and 2-star ones. That's where reliability problems show up first.
4. Read independent reviews from outlets that do real testing (Wirecutter, Will Prowse on YouTube, Outdoor Gear Lab, RTINGS where applicable).
5. Compare across our own catalog. A unit doesn't exist in a vacuum — we surface the strongest competitor at the same price tier and write what's different.
6. Write the honest take. If a unit's a bad buy, we say so. If it's overpriced relative to a competitor, we point at the competitor.

What we don't do

• We don't accept manufacturer payments. Brands don't pay us for placement, ranking, or coverage.
• We don't accept review samples. If we ever do, we'll disclose it on the article and remove the unit from any "best of" list.
• We don't run our own bench tests. Anyone who claims they ran 14 standardized tests should show you the data. We don't have it, so we don't pretend.
• We don't fake field reports. When a blog post says "during a hurricane outage", that's a real-world scenario you should plan for — not a personal anecdote we made up.

How we make money

Every Amazon link on this site carries our affiliate tag (wattbunker-20). When you click through and buy anything on Amazon — not just the product we linked — we receive a small commission. The price you pay is the same. The seller is Amazon, not us.

That funds the editor, the writers, the hosting bill, and the time it takes to compare 17 units against each other and put it in a single page. It does not buy us off. We never accept payment from manufacturers in exchange for positive coverage.

Where our numbers come from

• Capacity, output, weight, cycles: manufacturer datasheets, cross-checked against the Amazon listing.
• Real-world recharge times, noise levels: manufacturer claims unless we cite a third-party tester.
• Pricing: Amazon, checked at publication. The "Last checked" date appears on every product page.
• Ratings and review counts: Amazon at publication. They drift; we re-check monthly for featured units.

Imagery and AI

WattBunker uses a mix of image sources, and we want you to know which is which:

• Product photos come from manufacturer press kits or official product pages, used under fair use for editorial review. When a brand provides usable assets, we link to the press kit on the product page.
• Blog hero images and lifestyle shots are frequently generated or edited with AI. They illustrate the topic; they are not photographs of real testing we performed. We design them to be clearly evocative rather than documentary, and we never use AI to fabricate a specific product or to imply we own a unit we don't.
• Schematics, callouts, and inline diagrams are hand-drawn or generated and labeled as such when relevant.

If an image on the site materially changes the meaning of an article and you suspect it misrepresents reality, write to wattbunker@xerberuz.com. We will replace it.

If you spot something wrong

Specs change. Firmware updates fix things. Companies stop selling units. If you see a stale spec, a broken affiliate link, or a recommendation that no longer holds, write to wattbunker@xerberuz.com. We re-check and update — or remove — within 14 days.
