About Power Bank Tests

Mission Statement

Power Bank Tests exists to make fast, safe, and predictable charging effortless. We decode USB‑PD, PPS, and multi‑port behavior and verify delivered watt‑hours across temperatures so you can match the exact power bank to your device, trip, and climate with confidence.

Brand Story

We started Power Bank Tests after too many trips where the spec sheet didn’t match reality. Phones that wouldn’t enter PPS fast‑charge, laptops capped below their advertised PD wattage, and 20,000 mAh packs that wilted in the cold. Instead of repeating marketing numbers, we built a protocol‑first, field‑tested approach: log the actual negotiation, measure delivered Wh under realistic loads and temperatures, and verify safety features and airline readiness. The result is scenario‑based picks backed by standardized runtime charts, recharge profiles, and derating curves.

From commuters and students who just need reliable top‑ups, to travelers who must pass carry‑on rules, to creators and gamers who require stable 45–100W power, to outdoor users managing solar intermittency—our recommendations are engineered for your specific use case. We publish transparent test data, simple compatibility guidance, and practical kits (e.g., “MacBook 67W train setup,” “Samsung PPS travel kit,” “Steam Deck flight kit”).

Our Team

• Protocol Engineer: Specializes in USB‑PD/PPS negotiation, verifying PDOs/EPR profiles, and e‑marker cable behavior to ensure devices reach intended fast‑charge modes.
• Field & Thermal Tester: Runs cross‑load tests, cold/hot derating (0°C, room, heat), and multi‑device scenarios to confirm real‑world runtime and stability.
• Safety & Compliance Lead: Confirms UN38.3/airline readiness, checks BMS protections, and reviews third‑party certifications, enclosure integrity, and labeling.
• Mobile Creator & Gaming Editor: Validates sustained power for cameras, gimbals, capture cards, Switch/Steam Deck, and USB‑C laptops under actual workflows.
• Data & Tools Editor: Maintains our runtime charts, “charges‑for‑your‑device” calculator, and recharge targets so you can plan weight, time, and budget.

We’re united by a simple belief: objective measurements beat marketing. If our logs show a mismatch, we’ll explain it plainly and suggest the right bank, cable, and charger to unlock the performance you expect.
