What we actually measure

Usable Capacity

Advertised Wh vs. actual output under load. Most stations lose 10-15% to inverter inefficiency — we measure the real number.

Charge Time Accuracy

Wall, solar, and car charging — timed from 0 to 80% and 0 to 100%. We flag units where the last 20% takes forever.

🔊

Noise Under Load

Fan noise matters if you're in a van, tent, or bedroom during an outage. We measure dB at 1 meter under various loads.

Not sure what you need?

Your use case determines the right capacity. Here's a quick guide.

1000-2000Wh. Run a fridge, laptop, lights all day. Pair with 200W+ solar.

🏠

Home Backup

2000-5000Wh. Keep fridge, router, and lights running through a 6-12 hour outage.
