Portable Power Station Specification & Runtime Index

We normalized manufacturer-published specifications for 16 current power stations and calculated comparable energy-density, output-density and standardized runtime metrics.

Key findings

What the normalized specs show

These findings describe the models in this index only. They are based on manufacturer specifications and transparent calculations—not hands-on performance tests.

Energy density

Jackery Explorer 1000 v2

45.0 Wh/lb, the highest nominal battery capacity per pound in this 16-model sample.

Output density

BLUETTI Elite 100 V2

72.0 W/lb, the highest rated continuous AC output per pound in the sample.

Solar-to-capacity ratio

OUPES Mega 2

A capacity-to-rated-solar-input ratio of 0.98 hours before real-world losses—the lowest in this sample.

Normalized index

16 models on the same yardstick

Runtime estimates assume 85% of nominal battery energy reaches an AC load. Actual results vary with inverter efficiency, load, temperature, battery state and firmware.

Methodology

How we built the index

Specifications were collected from official manufacturer product or support pages available on September 13, 2026. We record nominal battery capacity, rated continuous AC output, maximum listed solar input and published unit weight.

Wh/lb = nominal battery capacity ÷ published weight. W/lb = rated continuous AC output ÷ published weight. These metrics help separate storage portability from inverter portability.

Standardized runtime = nominal capacity × 0.85 ÷ load watts. The 85% factor is a common planning assumption we apply equally to every model; it is not a measured efficiency result for any individual unit.

Ideal solar ratio = nominal capacity ÷ maximum rated solar input. It intentionally ignores solar, controller and charging losses, so it is useful for relative comparison but not a real-world recharge-time promise.

What this study does not claim

We did not laboratory-test inverter efficiency, thermal throttling, noise, surge behavior, battery degradation or real solar harvest. Manufacturer ratings are not interchangeable with independent test results.

Why this matters

Two stations with similar capacity can differ substantially in weight, inverter output and solar-input ceiling. A home-backup buyer may rationally accept lower Wh/lb for higher AC output or home-integration features, while a mobile user may prioritize energy density.
