How we pick — and what we'll never do
BlackBox Supply does not hands-on test products, and we will never pretend we did. That sentence is the foundation of everything on this site. Here is exactly what we do instead — with receipts.
The one-paragraph version
We verify every spec against manufacturer documentation, weigh long-term owner reviews over launch-week hype, read and cite the professionals who do lab-test, screen for safety protections and recalls, and explain what actually matters in each category. Picks earn their place with evidence. Links may earn us a commission — the evidence comes first.
The research stack
Spec verification against manufacturer documentation
Every number we publish — peak amps, PSI, watt-hours, engine ratings — is traced to the manufacturer's own spec sheet, not the retail listing. When a listing claims something the manufacturer doesn't, we flag it or drop the product.
Owner-review analysis, weighted for time
We read long-term owner feedback — the six-months-later reviews, not the day-one unboxings. Patterns in durability complaints, support experiences, and cold-weather failures count far more than launch-week star averages.
Professional source scoring
Where hands-on lab testing exists (professional publications, independent test channels), we read it, weigh it by methodology quality, and cite it. We stand on the shoulders of people who actually put products on a bench — and we name them.
Safety and recall checks
Jump starters are checked for spark-proof and reverse-polarity protection claims; products are screened against CPSC and NHTSA recall databases before they enter a guide.
Category expertise over product hype
Most of our work is explaining what actually matters in a category — the specs that predict real-world usefulness and the ones that are marketing. If you leave knowing how to judge any jump starter, we did the job.
What we will never do
- Claim or imply we hands-on tested something we didn't. Every page carries the same disclosure: researched, not personally tested.
- Publish fake ratings, fake review counts, or star widgets we invented.
- Use fake discounts, countdown timers, or manufactured urgency.
- Let a commission decide a pick. Products earn their slot by spec and owner evidence; the affiliate link comes after.
- Quote a live price. Prices move constantly — we publish approximate ranges and tell you to confirm on the retailer's page.
How we make money
Outbound product links are affiliate links — mostly Amazon. As an Amazon Associate, BlackBox Supply earns from qualifying purchases, at no extra cost to you. Commissions never decide a pick, and we say so on every page a link appears. The full version is on the disclosure page.
