Here are the two I recommend. The Anker 548 (left) and the Anker Solix C300 DC (right). The Anker Solix C300 DC power bank station is available for $169, while the Anker 548 power station is available for $104. These two are much bigger than regular power banks, but still highly portable.

[pdf] It's a modular battery storage marvel combining 80MWh capacity with solar PV systems, designed to power 200,000 residents 24/7. But how does this system actually beat traditional diesel generators in cost and reliability?
[pdf] Jointly developed by China National Offshore Oil Corporation (CNOOC) and China Southern Power Grid (CSG), it is expected to be the largest parking shed distribution solar power generation project in Zhuhai of South China's Guangdong Province.
[pdf] The selection of the input-voltage, transformer, and converter power capacity of a large container energy storage power station, depends on several factors, including the size of the plant, the expected application scenario, the requirements of the grid, and cost-effectiveness.
[pdf] Capacitor power, P c (W) in watts is calculated by the product of current running through the capacitor, I c (A) in amperes and voltage running through the capacitor, V c (V) in volts. Capacitor power, P c (W) = I c (A) * V c (V) P c (W) = capacitor power in watts, W. V c (V) = voltage in volts, V.
