How long can your appliance run under limited electricity?

  Out of all the developed countries, the U.S. has more power outages per year than any other. Sometimes, it’s minutes in the dark. More commonly, hours. On the more extreme occasions, days, even.

  According to the American Society of Civil Engineers, there were close to 4,000 power outages throughout the United States in 2017, with the number increasing since then. In February 2021, Texas saw one of the worst power outages in US history, leaving 4.5 million homes and businesses without power in the middle of winter, leading to at least 151 deaths. The main reasons for the increased vulnerability of the grid are the progression of climate change and the deterioration of electrical infrastructure.

  Given the ever-growing loss of grid power, it’s important to plan ahead and be well prepared for any power emergency, like a power outage or an impromptu blackout, in order to dissipate concerns and feel safe at home.

  One way to do so is by having your own power station at home to use as a backup generator.

  In order to make the most out of a power station and plan accordingly, it’s important to understand how they work.

  First, you have to distinguish whether your device has batteries or not. For any device with a built-in battery, we calculate how many charges the device can get once plugged in. For devices solely relying on an external power source, we calculate how many hours this power bank will last once plugged in.

  The performance of power stations can be easily calculated using ‘Watt Hours’.

  ‘Watt Hours’ (Wh) measure the estimated amount of energy consumed by an electrical appliance when left on for one hour. For example: One Watt Hour is equal to one Watt of power flowing for an hour.

  The ‘wattage’ use of any appliance should come written on its label, instructions, or stamped on the back or bottom of the appliance.

  You could even calculate how much Watts would be consumed by an appliance per minute, by dividing the wattage by 60 (Wh/60 = power consumed by minute). This gives you the ability to know the exact electricity consumption of any appliance against the energy capacity of your power station.

  To find out how many hours of power a power station can provide to a specific device, you can just multiply appliance watts (The Wh consumed by an appliance) x hours of use per day. For example, a microwave requires around 800Wh. However, we tend to only use them for 1 or 2 minutes at a time. So if we divide 800 Wh / 60 minutes, we find out microwaves consume 13Wh per minute. Even when used for 10 minutes a day, they only spend 130Wh per day.

  Other concepts important to take into account are maximum voltage (Max voltage) and maximum power voltage.

  Max voltage represents the highest voltage rating a specific electrical device can withstand.

  Every appliance comes with a voltage rating and can operate within it for “infinite time” without causing damage to its insulation, provided it’s receiving power. It’s important to understand this rating to prevent damage to either insulation or the device itself.

  Maximum power voltage represents the greatest point for power output, and the preferred/suggested voltage in order to charge or power something up effectively.

  It’s important to know this because in case you’d only know the amps (amperage, the amount of electric current that flows to a specific device), you can multiply that x V (Voltage), in order to find out the Watt-hours a device consumes. Simply put, (amps x V = Wh).

  A TV consumes 70Wh on average. 557Wh / 70Wh = 8 hours of TV to keep you from boredom during an outage.

  A Wi-Fi router tends to consume 10Wh. 557Wh / 10Wh = 55.7 hours of the internet to stay reachable through your phone.
