Positives: quiet, carrying handle, weight / kWh, port covers, light, seems fairly robust
Negatives: final 20% or so of charge drop very quickly; strict overload protection in spite of advertized surge power capacity
Overall, works great for powering a refrigerator and mobile devices in my off-grid cabin for about 4 days. But it cannot power my 1.6 kW chop saw due to surge power at start-up, which leaves me disappointed.
