Ukraine is making large-scale use of portable power stations. They offer fast AC charging, DC charging, rapid discharge, high-speed USB-C ports, built-in DC to AC inverters, and more.

However, most power stations only have a capacity of 1 or 2 kWh. That’s the major limitation: capacity.
You can increase capacity by buying larger models or brand-specific expansion batteries — but those solutions are expensive.

Eyes on Ukraine now has a solution.
We expand power stations using:
🔋 5kWh server rack batteries
🔋 5kWh golf cart batteries
🔋 2.5kWh general purpose batteries

With a custom-built cable, these batteries connect directly to the internal battery of the power station, instantly expanding its capacity. Even better: charging the external battery is handled through the power station’s own charging system.

In the coming period, we’ll present solutions for:
• EcoFlow Delta 2
• Fossibot F2400

We are also exploring expansion options for other brands.
