Guide On How To Stay Online With Your Home Wifi During A Power Outage

Tech | November 24, 2023

Staying online all the time is very important nowadays especially for those who are working from home or having an online class. However, in a country like the Philippines where power outage (brown-out or black-out as other people will call it) is very common, staying online at all times is a great challenge.

There are multiple ways to overcome this challenge but one of the simplest ways is to use a powerbank and a 12V DC converter cable. But before you buy these two equipment you need to check first the power requirements of your wifid device.

Power Requirements of Wifi Device

Before anything else, it is important that you check the power requirements of your wifi device. This is very important because you will need this information to identify the specs of the powerbank and the cable converter that you will need. Usually home wifi devices only requires a 12V/1 Ampere of input power or basically 12-Watts ofpower. You can check the input power requirements at the back or bottom portion of your device.

Once you will identify the power requirements of your device, the next step is to identify the capacity of your converter cable and powerbank. In this guide, I am using my Globe-At-Home wifi that requires 12-Watts of power. So my goal here is to generate that power so that my Globe-at-home prepaid wifi device will function properly when connected to a powerbank.

Now that you know how much power you will be needing, the next thing that you will need to do is to check the power output of your powerbank. If your powerbank can generate 12-watts of power, all you need to do next is to find a USB to 5mm round tip cable. However, if your powerbank is not capable of producing 12-Watts of power you are going to need a 12V DC converter cable.

Most powerbank indicates an output in voltage (V) and current (I). In this case you will need to compute the power (P). To do this, just multiply the Voltage (volts) to the indicated current (ampere). This is mathematically depicted as P = V x I. So, if you have a powerbank that has an output of 5 Volts and 1 Ampere that will only give you 5-watts of power. That powerbank cannot definitely power your wifi device because it needs 12-Watts of power. This is the time that you will need the 12V DC converter cable mentioned earlier. You can buy this cable here in Lazada.

On the other hand, if your powerbank has an output of 6V/2A, then that means your powerbank can generate 12-Watts of power which is just enough to power your wifi device. In this case all you need is the USB to round tip cable.

This is how the final setup looks like, just very simple, right?

Once you have all the requirements above, you can now start using your wifi without plugging it into the 220-Volts power outlet. Just connect the cable to the 12-Watts powerbank. Then connect the other end to your home-wifi. Now you can be online even during black-out or when there is a power outage in your area.

I think you can also try this method with PLDT-Home wifi. If you have tried it please let us know in the comments below.
