Antigravity Batteries PS-45 Runtime Calculator
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.

Catalog notes (original English)
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 estimate
Formula starting points use each scenario’s default watts, duty cycle and output path, with 10% reserve or 15% for CPAP. Linked detail pages use the same inputs. Hours apply only if the device can run and start; they are not measured runtimes.

Runtime calculator
Runtime is conditional on successful startup, compatible voltage/connectors and sufficient output. Verify the actual device setup before relying on these hours.

This is an estimate. Real runtime changes with load, temperature, battery age, AC/DC output, and device behavior. Runtime is conditional on successful startup, compatible voltage/connectors and sufficient output. Verify the actual device setup before relying on these hours.
2h 7mEstimated runtime: 2h 7mThis setup is tight. Reduce load, use DC where possible, or choose a larger station.

Estimated2h 7m
Optimistic2h 38m
These are calculated sensitivity cases, not a statistical confidence interval. Conservative uses lower efficiency and battery health, more reserve/temperature loss and higher load; optimistic changes these assumptions in the opposite direction.

Planning notes
- Capacity class: 166 Wh. Size the battery for your measured average load and required hours, including reserve.
- Tracked output: 100 W. Compare both running demand and startup demand before using any runtime estimate.
- Solar input limit: unknown. Actual refill depends on panel voltage/current compatibility, sunlight, angle and charging losses.
Known data gaps
- Unverified or missing specifications remain visible. The confidence label describes the station record, not a tested runtime or approval for emergency use.
- Weight: 1.3 kg. Check the complete carrying setup, cables and battery extensions before choosing this model for travel.
- unknown: USB-C output, Solar input
Models: Antigravity Batteries
Compare nearby capacity records from the same brand, then check output, weight and missing fields. A larger battery does not establish device compatibility.
