When there is a power outage in your home or an emergency, you can use a car battery as an energy backup. Do you know how you can power your household items with a car battery? Well, if you don’t know, there is no cause for alarm because we have got you covered, and we’re going to show you how to do that shortly. Stay tuned!
While the car battery may not power all your household items, it can power essential items, like LED light bulbs or lamps, phone charging, a portable Wi-Fi router, small fans, etc. However, before you can successfully power your household items using a car battery, you will need an inverter that will convert the direct current (DC) in the battery into alternating current (AC) for your household items. Most of the household items use alternating current; hence, you need an inverter.
What you Should Know Before using a Car Battery to Power your Household Items
Before you start using a car battery to power your household items, you should note the following:
- Ensure that your car battery is fully charged and it is in good condition
- You will need an efficient power inverter that can convert DC (from the battery) to AC (what home appliances use)
- You need a jumper cables or a direct plug-in to your car’s DC outlet
- Additionally, you need to have basic knowledge of wattage limits—most car batteries can safely power items under 300 watts continuously.
Having said this, let’s proceed with our discussion
Household Items You Can Power with a Car Battery in Emergency
There are many household items that you can power with a car battery when there is an emergency, but we are going to focus our discussion on the most common household items that we use daily. Let’s proceed!
1. LED Light Bulbs or Lamps
One of the household items that you can power with your car battery during an emergency is LED light bulbs or lamps. This is possible because LED lights consume very little power, usually around 5–15 watts per bulb. This means that with a 300W inverter, you can power multiple LED bulbs or a small lamp for several hours using a single car battery.
2. Charging of Phones and Laptops
You can also use your car battery to charge smartphones, tablets, and laptops via a car charger or inverter. Most phones need about 5W–10W, while laptops usually require 45W–90W. This means that a fully charged car battery can recharge a phone multiple times and even keep your laptop going for a while.
3. Run a Small Fan
Car batteries can also power small electric fans in your home. During hot weather, you can power your small DC or AC fan (30W–60W) with your car battery for a few hours.
4. Power a Portable Wi-Fi Router
Most modern routers only use around 10W–15W. This means that car batteries power them for hours. If your internet service is still active (e.g., via fiber or cable), you can power your Wi-Fi router, which can help you stay connected with emergency services or loved ones.
