Why You Should Always Keep Three Devices Connected to a Portable Power Station

Portable power stations are often seen as solutions for emergencies—such as power outages or camping trips. However, using them as uninterruptible power supplies (UPS) can prevent numerous issues. A smart home technology expert explains why three key devices should always remain connected: a router, refrigerator, and security system.

The most critical device is the router and modem. Losing internet access during a power outage can be a major inconvenience, especially for remote workers. Mobile networks quickly become overloaded when thousands of users simultaneously lose their home Wi-Fi. A compact power station, like the EcoFlow River 3 Plus (286 Wh), can keep a router running for a full workday, while more powerful models can last several days. This is also essential for smart homes, where remote control depends on stable internet connectivity.

The refrigerator is another appliance worth connecting to backup power. Modern models consume just 1–2 kWh per day, making them compatible with portable power stations. For example, the EcoFlow Delta 3 Max (2048 Wh) can support a full-sized refrigerator for up to three days. It’s important to account for the compressor’s startup current, which can reach 1500 W, so the power station must have sufficient capacity. Connecting a refrigerator to a backup source prevents food spoilage and saves money on replacements.

Security systems also require constant power, especially during outages. Many cameras and hubs have built-in batteries, but they rely on stable internet access. Connecting a hub or PoE switch to a power station ensures continuous operation. Even a small model, like the EcoFlow River 3 (245 Wh), can power cameras for several hours. This is particularly valuable for remote home monitoring during trips or emergencies.
