1. Affiliate Disclosure (FTC 16 CFR Part 255)
RuntimeVerdict maintains strict separation between our electrical math engine and retailer compensation. Affiliate codes (when active) never alter inverter tare constants, surge failure flags, or UPS transfer thresholds.
RuntimeVerdict participates in direct manufacturer affiliate programs (including EcoFlow, Anker SOLIX, Bluetti, Jackery, and energy infrastructure partners) as well as retail affiliate programs such as Amazon Associates. When you click an outbound product or accessory link marked with rel="sponsored" and complete a qualifying purchase, RuntimeVerdict may earn a referral commission at zero additional cost to your checkout price.
2. Electrical Safety & Residential Code Disclaimer
All calculations, runtime graphs, and printable fridge-door checklists generated on RuntimeVerdict are provided strictly for educational planning and preliminary load sizing. Portable backup power equipment carries high current, stored chemical energy, and potential shock or fire hazards if misused.
- Never Use Backfeed Suicide Cords: Connecting a male-to-male cord between a portable power station and a wall outlet risks fatal electrocution for utility line workers and fires inside home branch wiring. Always install a UL-listed manual transfer switch or mechanically interlocked generator inlet box through a licensed electrician following National Electrical Code (NEC Article 702) and local permitting rules.
- Medical Life-Support Equipment: Portable consumer battery stations are not FDA-cleared hospital uninterruptible power supplies. Patients dependent on stationary oxygen concentrators, ventilators, or critical medical devices must maintain redundant compressed oxygen cylinders and register for utility priority restoration lists.
- Neutral-Ground Bonding Caution: Only employ neutral-ground bonding plugs on isolated transfer circuits or direct standalone furnace cords where explicitly verified safe by equipment manuals and never while AC grid pass-through input remains connected.
3. Data Sources, Corrections & Spec Updates
Hardware specifications are cross-checked against manufacturer electrical manuals, independent oscilloscope switchover testing, and measured quiescent wattage logs. Street deal prices reflect recurring holiday seasonal ranges and may vary dynamically by retailer inventory.
Because firmware updates, mid-cycle inverter hardware revisions, and BMS cold-weather cutoffs evolve across product generations, no published bench audit is treated as permanent. Readers and manufacturers may submit verifiable watt-hour logger captures or updated safety notices to hello@runtimeverdict.com. Confirmed engineering adjustments are published openly without commercial favoritism.
