In accordance with the Federal Trade Commission’s Guides Concerning the Use of Endorsements and Testimonials in Advertising (16 CFR Part 255), we provide full transparency regarding our monetization and product testing policies.
1. How We Earn Support
90daypoweroutage.com is reader-supported. Some of the outbound links on this website are "affiliate links." If you click on an affiliate link and make a purchase from a merchant (such as Amazon, Home Depot, EcoFlow, or specialized preparedness retailers), we may receive a small referral commission.
This commission comes at zero additional cost to you. In fact, we frequently negotiate exclusive discount codes that reduce the price below standard retail.
2. Strict Separation Between Editorial and Revenue
- No Pay-to-Rank: No brand, vendor, or manufacturer can pay to be included, featured, or ranked #1 on our website. All rankings are determined purely by our documented 100-point testing scoresheet.
- No Sponsored Reviews: We do not accept paid posts or sponsored advertorials disguised as objective journalism.
- Mandatory "Who It Is NOT For": Every product we evaluate must explicitly document its operational limitations, failure modes, and who should NOT buy it.
- Search Engine Attribute Tagging: All outbound commercial links carry
rel="sponsored nofollow"attributes in compliance with Google and Bing webmaster guidelines.

| Engineering Accuracy | 25 Points | Verified continuous vs surge Watts; true Wh battery capacity under load; pure sine wave <3% THD. |
| Field Serviceability | 20 Points | Availability of replacement spark plugs, carburetors, impellers, and standard connector ports (MC4 / XT60). |
| Value & Efficiency | 15 Points | Cost per Watt-hour ($/Wh) for batteries; fuel burn rate at 50% load factor for combustion units. |
