EV Rescue And Remote Site Power Supply Trolley Style Off Grid Power Station 3.5kWH LFP 51.2V Expandable Mobile Energy Storage Power Bank

EV Rescue And Remote Site Power Supply Trolley Style Off Grid Power Station 3.5kWH LFP 51.2V Expandable Mobile Energy Storage Power Bank

1. Product Description

This 3.5kWH wheeled mobile energy storage power bank adopts lithium iron phosphate battery pack, delivering reliable off-grid power for temporary electric vehicle charging and mobile power needs across multiple working sites. It accepts AC input voltage of 186V to 236V and supports both 50Hz and 60Hz grid frequency. The inverter supplies rated continuous power of 3500W and peak burst power of 7000W, activating protective cut-off once power exceeds 3700W. Its battery system runs at rated 51.2V within 48V to 57.6V operating voltage, supporting maximum 15A constant current charging. At 220V input condition, the unit reaches up to 92% working efficiency. Built as a trolley suitcase design with wheels, it measures 466230550mm, net weight 39kg and packaged weight around 55kg. It can work with solar power for green energy supply, and cuts the heavy expense of cable laying and site reconstruction. It is widely applied in highway service areas parking lots service stations commercial premises and fleet charging operations. (Word count:199)
