Affiliate Disclosure & Algorithmic Independence
WattGrid Lab provides 100% free, ad-clutter-free electrical load modeling, LRA motor surge calculators, and printable outage charts without paywalls or email gates. To fund ongoing server infrastructure and specification audits, we participate in affiliate marketing programs.
1. Amazon Associates & Direct Brand Partner Programs
WattGrid Lab is a participant in the Amazon Services LLC Associates Program, an affiliate advertising program designed to provide a means for sites to earn advertising fees by advertising and linking to Amazon.com. As an Amazon Associate I earn from qualifying purchases.
We may also maintain direct affiliate partnerships (via networks such as Impact, CJ Affiliate, or Partnerize) with portable power and generator manufacturers including EcoFlow, Bluetti, Jackery, and Anker SOLIX. Clicking an outbound merchant link (marked with rel="nofollow sponsored" and target="_blank") never increases the price you pay.
2. Strict Physics-First Hardware Filtering
No manufacturer can pay to override our electrical sizing equations. Every power station or generator surfaced in our Hardware Matchmaker is deterministically filtered against your calculated:
- Continuous running wattage + NEC 20% headroom buffer
- Peak inductive motor Locked Rotor Amp (LRA) startup surge
- 120V single-phase vs. 240V split-phase voltage requirement
- Pure sine wave (<3% THD) electronic safety requirement
If a sponsor's power station cannot safely start your 1/2 HP sump pump or 240V deep-well motor, our algorithm disqualifies it automatically.
