Keep WiFi router on during loadshedding

Tired of your WiFi and Internet connection cutting out every time Eskom decides to enforce the infamous Load Shedding? Unfortunately, it looks like it is not going anywhere, any time soon. Although there is no cure for Load Shedding, a Mini Load Shedding UPS will help you stay connected to the internet!

Being without lights, the kettle or toaster for a couple of hours is not a total train smash, but being without WiFi, now that's another story, For small businesses and home offices, these couple of hours are crucial. Communication, online sales, research, payment gateways, management, social media networks and much more are essential in the business world. Without access to the Internet during Load Shedding, there is a lot to lose.

However, there IS an easy way to stay connected during periods of power outages, or as South Africans know it as - Load Shedding. Click here to see Recommended Load Shedding Mini UPS Devices.

How do you keep the WiFi router on during Load Shedding?

The easiest and cheapest option to keep your WiFi router running during a power cut is to use a small DC-to-DC UPS. A UPS (Uninterruptible Power Supply) is a small-to-medium sized device that provides back up power when the electricity goes off. A UPS holds a battery that starts to work when the device senses a loss of power from its primary source.

The size and design of the UPS will determine how long it will supply power for. Most UPS devices are designed to a group of electronic devices for a few minutes only - temporary power cuts that affect a running server, a group of computers and screens, etc. Some small UPS devices though are designed to supply a low-power DC apparatus. Those Mini UPS units typically use lithium batteries with a total capacity of 8800mAh. They can supply a router or a security camera for up to 4 hours, making them ideal for load shedding power interruptions.

Advantages of a Load Shedding Mini UPS (DC-to-DC Uninterruptible Power Supply )

  • No interruption - Your WiFi router, security cameras or other small DC devices will stay powered with no interruption
  • Multiple charging options - USB, DC, PoE and solar charging options (more on this below)
  • Selectable DC output voltages - 9V and 12V are the most common voltages needed for small DC devices, but some DC-to-DC UPSs also offer 5V, 15V and 24V
  • Lasts enough time - Batteries ensure the system lasts 4 hours
  • Battery capacity LED indicator - Notifies you when it is time to charge

How does a Mini UPS work?

Unlike a traditional power bank that solely provides backup power when needed, a UPS remains in-line between your DC devices and the main power source. When the power drops below (or surges above) safe voltage levels, the UPS switches over to DC battery power to run connected devices. DC-to-DC UPSs are designed for WiFi routers, phones, tablets, small POS systems, security cameras and other low-power DC electronic equipment. They are not suitable for refrigerators, televisions, lights, pumps and other heavy-duty, AC appliances and equipment.
