NEWSMY P72 Runtime Calculator
Use this source-linked record to estimate runtime from tracked capacity, output, charging, and weight fields. Unknown specs stay unknown until an official or manufacturer-grade source confirms them.
Quick answer: the NEWSMY P72 stores 270 Wh and delivers up to 268 W of continuous AC power. Under this site's planning assumptions (85% inverter efficiency, 10% reserve), a steady 100 W AC load runs for roughly 2.1 hours. Last source check: 2026-08-27. This is an estimate, not a guarantee.

NEWSMY has no reachable English first-party storefront for this model, so this record uses a retailer-published copy of the manufacturer specification table and stays at estimated confidence. Chemistry, surge and DC ceilings stay unknown because the table publishes none.
Runtime Starting Points
These are formula estimates using the tracked capacity, a 10% reserve, and each scenario's default wattage and duty cycle. They are planning starters, not measured runtimes.

Good fit when
- Capacity is a compact class; use it for small electronics and short essentials rather than high-wattage appliances.
- Tracked AC output is 268 W, so high-draw appliances and tools need careful filtering.
- USB-C output is tracked at laptop-class power, useful for direct DC charging when the device supports it.
- Tracked solar input is 100 W before panel, weather, angle, and controller losses.
Watch out for
- Surge output is unknown, so do not assume compressor, pump, or power-tool startup will work.
- Still unknown in the source-backed record: battery chemistry, surge output, dc output.
- Confidence is not marked verified; keep the linked source context visible before making a purchase or emergency plan.
