## Introduction

Portable power stations are handy for charging devices like phones and laptops during power outages. However, running larger appliances like refrigerators requires more robust solutions. CNET's lab tests have identified the most efficient products to meet this need.

## Tested Products

CNET tested 19 large and extra-large portable power stations, evaluating how long they could run a refrigerator. The tests showed that larger capacity models don't always last longer, with efficiency playing a critical role.

## Top Performers

The Fossibot 3600 Pro performed best, running the test fridge for 44.65 hours (1.86 days). The Oupes Mega 5 came in second at 43.72 hours. Smaller models like the Bluetti AC200L also performed well due to their efficiency.

## Efficiency Awards

CNET identified the most efficient power stations in each size category: UDPower AC0600 (small), Bluetti Elite 100 V2 Bio-Based (medium), Bluetti Elite 200 (large), and Jackery HomePower 3600 Plus (extra-large).

## Fast Charging

The Oupes Mega 1 Lite charged fully in just 44 minutes, making it the fastest-charging unit. This feature is crucial for quick readiness in emergencies.

## Testing Method

Each power station was tested by running a full-size fridge (Whirlpool, 60Hz, 118V) until the battery drained. Tests were designed to reflect real-world usage, with efficiency measured using standard procedures.

## Unexpected Results

Some high-capacity models (like the Anker Solix F3800 Plus) underperformed, while smaller models like the Bluetti AC200L excelled due to efficiency. This proves that efficiency is as important as capacity.

## Internal Consumption Metrics

Tests measured the energy consumed by the power stations themselves (inverter overhead). Models like the Fossibot 3600 Pro minimized this loss, directing more energy to the fridge.

## Best for Large Appliances

While extra-large models like the Fossibot 3600 Pro and Oupes Mega 5 led in absolute performance, efficient large models like the Bluetti AC200L and Anker Solix C2000 Gen 2 also stood out, offering better value and portability.

## Rankings and Results

All tested units were ranked by fridge runtime. The Fossibot 3600 Pro (44.65 hours) and Oupes Mega 5 (43.72 hours) topped the list, while the OSCAL Power Max 2400 (12.58 hours) had the shortest runtime.

## Recommended Product

The Fossibot 3600 Pro (extra-large) and Bluetti AC200L (large) emerged as the top recommendations, excelling in both performance and efficiency.

## Conclusion

CNET's extensive tests show that portable power stations are a practical solution for running large appliances during outages. Choosing the right product based on efficiency and capacity balance ensures your essential needs are met even during emergencies.
