The Solar Generator 2000 Pro is the latest outdoors/backup generator from Jackery that can charge using solar panels. In fact, the OEM asserts that it can re-charge to 100% in this way in just 2.5 hours - so long as enough new same-brand panels are hooked up to the portable power station. It is also rated to charge from the mains in 2 hours to sustain a range of devices, even household appliances, in turn.
