Loadshedding often causes internet interruptions because routers and fiber ONT devices require electricity to operate. When the power goes off, both devices usually shut down immediately, cutting off your WiFi connection.
Fortunately, there are several ways to keep your internet running during loadshedding.
In this guide we explain the most common backup solutions used in South Africa and how they work.
Why WiFi Turns Off During Loadshedding
Most home internet setups rely on two devices:
- Fiber ONT (optical network terminal)
- WiFi router
Both require electricity to operate. When loadshedding begins, these devices stop working unless they are connected to a backup power source.
You can learn more in our guide explaining why WiFi turns off during loadshedding even when using a UPS.
Option 1: Mini UPS for Router
The most popular solution is a mini UPS designed for routers and fiber equipment.
These small battery backup units automatically supply power when loadshedding begins.
Advantages:
- automatic power switching
- simple installation
- reliable runtime
Many mini UPS devices can keep your internet running for 4 to 6 hours depending on the battery size.

Option 2: Power Banks
Some people use large power banks with adapter cables to power routers.
This method can work in some cases, but it usually requires additional cables and manual setup.
Power banks also tend to provide shorter runtime compared to dedicated mini UPS devices.
Option 3: Inverter Systems
Households with larger backup power systems may use an inverter and battery setup.
These systems can power:
- routers
- fiber equipment
- lights
- laptops
However, inverter systems are typically more expensive and are designed for powering multiple appliances.
Option 4: Portable Power Stations
Portable power stations are larger battery devices that can power several appliances at once.
They can easily keep routers and internet equipment running during loadshedding but are usually more expensive than mini UPS devices.
Which Option Is Best?
For most households in South Africa, the simplest solution is a mini UPS designed for routers.
These devices are affordable, easy to install, and can provide several hours of backup power during loadshedding.
Larger backup systems such as inverters or portable power stations are better suited for powering multiple appliances.
Final Verdict
Keeping your WiFi running during loadshedding is possible with the right backup power solution.
Mini UPS devices remain the most practical option for powering routers and fiber equipment because they are simple to install and designed specifically for networking devices.
For households that require longer backup power or want to run additional appliances, inverter systems or portable power stations may be worth considering.
