The battery also supports flexible charging options. You can recharge it via wall sockets, solar panels, or a car outlet. The 140 W USB-C port allows both input and output, giving you fast charging for laptops, tablets, and other modern devices.
Safety is a priority. The built-in Battery Management System (BMS) provides complete protection against overvoltage, overcurrent, and overheating. This ensures your battery remains safe in different environments, whether you are indoors or outdoors.
Another advantage is the EcoFlow mobile app. With the app, you can track battery status, monitor charging progress, and control power usage. This smart monitoring system gives you full control over your portable energy anytime, anywhere.
Whether you are camping in the wild, traveling across the country, or preparing for a power outage, the product gives you peace of mind. It provides more hours of reliable energy, protects your devices, and delivers flexibility when you need it most.
