I have a new EcoFlow river Pro Portable Power Stations up for grabs. I had plans to incorporate into my greenhouse power back up but decided to go a different direction. My loss, your gain. Looking for $300, no Low Ballers pls. These are really nice and compact power stations.SpecsNet Weight16.8 lbs 7.6kgDimensions11.4 x 7.1 x 9.3in 28.9 x 18.0 x 23.5cmCharge Temperature32 to 113F - 5F 0 to 45C - 3CDischarge Temperature-4 to 113F - 5F -20 to 45C - 3CColorBlackWarranty24 monthsCharging MethodAC Wall Outlet, 12V Car Adapter, Solar PanelsFull Recharge Time1.6 Hours AC 8 Hours 12V Car Adapter 4-8 Hours Using 2x 110W Solar Panels in parallel with direct sunlight 6-12 Hours Using 1x 160W Solar Panel with direct sunlightCapacity720Wh 28.8VCell ChemistryLithium-ionCycle Life800 cycles to 80 capacityManagement SystemsBMS, Over Voltage Protection, Overload Protection, Over Temperature Protection, Short Circuit Protection Low Temperature Protection, Low Voltage Protection, Overcurrent ProtectionAC Charge Input PowerX-Stream Charge 660W MaxAC Charge Input Voltage100-120Vac 50Hz60HzSolar Charge Input200W 10-25Vdc 12A MaxCar Charger12Vdc 8A MaxAC Output x3600W Surge 1200W total, 120Vac 50Hz60HzUSB-A Output x25Vdc, 2.4A, 12W Max per portUSB-A Fast Charge x15V2.4A,9V2A,12V1.5A 18W MaxUSB-C Output x15Vdc, 9Vdc, 12Vdc, 15Vdc, 20Vdc, 5A, 100W MaxCar Power Output x1136W, 13.6Vdc, 10A MaxDC5521 Output x213.6Vdc, 3A Max per port
