During a power outage, it is vital that you have a generator especially if you have a lot of perishable items in your fridge and freezer. With each power outage, there is no guarantee when the power will come back, so you should power only the vital appliances like the freezer, refrigerator, heater, or air conditioner.

A 3000-watt generator serves as a dependable backup power solution for homes or offices during power disruptions or outages. With its sufficient power output, this type of generator can effectively run essential appliances and devices including refrigerators, freezers, lights, computers, phones, and crucial equipment for individuals who are elderly or have medical needs.

If you plan to power your appliances during a power outage then you might find that a 3000 watt generator might not be enough, mostly because of the increased starting power needed for some of the appliances this is why my personal recommendation is to get a 3800 watt power generator which has 4750 watts starting power Click here to check it out on Amazon.com

No matter if you are a prepper or not, you should still own a generator. In today’s world, we are extremely reliant on electricity, and life, as we know it today, wouldn’t be possible without it. Although electricity brings us a lot of benefits, but it is also our biggest weakness. There are a lot of things that could disrupt electricity locally and even nationwide. A long-term blackout can not be ruled out, accidents happen, and so do natural disasters or even people who just want to take the entire power grid down.

You might think that once the power is out it will be only a matter of time, usually a couple of hours till you get electricity back. The problem is that you do not have any guarantee of this happening. Generally speaking, most of the time when the power goes down is due to the malfunction of the power grid, depending on how severe the damage is it will take anything from a couple of hours to a couple of days to get the power back.

The main risk of not having a power generator during the summertime when the power goes out is that your air conditioner will not work and the food in your fridge will probably spoil. On the other hand, if the power goes down during wintertime you might find yourself in serious trouble if the power goes down for several days and you do not have a generator. Without electricity, your heater will not work, and it is a fairly high probability that most utilities will also not be available.

Not only your house will slowly start to cool down, but the water in your pipes might even freeze, which will cause extensive damage. Once the water turns into ice, it expands and it will cause fissures in your water pipes. Once the power comes back, you will probably start the heater in order to heat up the house, once you do in a matter of minutes you will hear your pipes making a lot of noise as they will start to violently shake and probably burst due to the ice blocking the pipes, and all this could have been avoided with having a 3000-watt generator.

Just as a side note, most appliances will need more power when they are starting up, which will increase the load of the generator and this is why some generators will have two power stats, like the starting power output and the working power output. If you are planning to use several appliances and devices to power with a generator then hook them up to the generator one by one, and allow them a couple of minutes to get power before you hook anything else in, especially for bigger appliances like refrigerators and heaters.
