Terms of Use & Affiliate Disclosure

Last updated: February 7, 2026

Affiliate disclosure

Portable Power Nerd is reader-supported. Many of the outbound product links on this site are affiliate links, which means we may earn a commission when you click through and make a purchase — at no extra cost to you. This is how we fund the research and keep the content free.

As an Amazon Associate, we earn from qualifying purchases. We also participate in affiliate programs with brands and networks including EcoFlow, Bluetti, and Jackery. A commission never changes our recommendation: we decide which unit is best before any link is added, and we regularly recommend the unit that's right for you over the one that pays most. For the full picture of how we stay independent, see our Editorial & Review Policy.

Informational use only

The content on this site is provided for general informational purposes. We work hard to keep specs, prices, and runtime estimates accurate, but product details and availability change frequently and errors happen. Always confirm current specifications and pricing on the retailer's or manufacturer's page before you buy. Runtime figures on this site — including any calculator results — are estimates based on typical power draw and published data; your actual results depend on your specific equipment and settings.

Not medical or professional advice

Some guides discuss powering CPAP machines and other equipment during outages. This is general information to help you plan backup power, not medical advice. Follow your device manufacturer's instructions and consult your healthcare provider about your therapy. Working with electricity and batteries carries risk; follow all manufacturer safety guidance.

No warranty

This site is provided "as is," without warranties of any kind. To the fullest extent permitted by law, Portable Power Nerd is not liable for any loss or damage arising from your use of the site or reliance on its content or third-party links.

Intellectual property

The articles, graphics, and original artwork on this site are our property and may not be reproduced without permission. Brand names and trademarks belong to their respective owners and are used for identification and comparison only.

External links

We link to third-party sites (retailers, manufacturers, references) for your convenience. We don't control those sites and aren't responsible for their content or practices.

Changes

We may update these terms; the "last updated" date reflects the latest revision. Continued use of the site means you accept the current terms. Questions? Contact us.
