Antigravity Batteries PS-45 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 Antigravity Batteries PS-45 stores 166 Wh and delivers up to 100 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 1.3 hours. Last source check: 2026-08-27. This is an estimate, not a guarantee.

Antigravity is explicit that the 200W peak is a two-second rating, so treat 100W as the working ceiling. DC output is derived from the published 12.5V/10A limit. The unit has no USB-C port and Antigravity quotes solar only as an 18V tip voltage with no wattage, so both stay unknown. Weight is converted from the published 2.86 lb figure.
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 100 W, so high-draw appliances and tools need careful filtering.
Watch out for
- Surge output is tracked, but device startup behavior should still be checked against the actual load.
- Still unknown in the source-backed record: usb-c output, solar input.
- Confidence is not marked verified; keep the linked source context visible before making a purchase or emergency plan.
