Overall, a great product, really makes me more conscious of my energy use, and more prepared for blackouts. Two fairly minor bug bears:
1) Today I tried plugging in only one panel, and got 104W input, slightly above the rating of one panel (100W)! But on plugging in the second one, I only got up to 125W, in the same sun, so I wonder if that's the unit's maximum input level? The specs say it can take up to 24V 7.5A, which would equate to 180W, but maybe with the 18V panels it can only do 18V*7.5A=135W?
2) When plugging in a 220V load over ~60W, a fairly loud fan (dB meter on phone says ~46dB measured at 1 meter distance) starts and does not ever stop again (it seems) until I switch the AC supply off. A fan regulated by thermocouple that automatically comes off again would be preferable.
supplemental: Just after submitting this review, the Jackery while connected to about 55W AC load turned the fan on for a few seconds and then switched it off again. It must have sensed the constructive criticism ;) when connected to say 300 Watts even just for a few seconds though, the fan seems to never come off again.
