Top 5 U.S. states for power outages

Power outages can happen at the most inconvenient times, and many people consider purchasing a backup battery as a solution.

However, before doing that, it's important to know which states have the most outages so you can find the backup battery that is right for you.

What to consider when buying the best backup battery

There are a lot of options out there for backup batteries. Some of these options include solar, generators, and other forms of storage. If you're considering buying a backup battery for a power outage, you should take note of the following: size, shape, cost, and how long the charge lasts. Of course, these are all different factors, so you should consider each of them when looking at the best battery for a power outage.

Sine wave inverter: This is the most efficient IGBT type of power supply. It can effectively reduce the voltage drop by as much as 40%, which is almost equivalent to the cost of the inverter.

Output:  No matter what power supply you choose, the output power should be at least 90% of peak power. This is the most important factor, which determines the life of the backup battery. The backup battery needs to have sufficient output power for charging.

Note: It is not good if the output power is less than 20% of peak power.

Safety circuiting: The backup battery should have proper safety circuiting. If the battery is not well protected, it can be short-circuited. Safety circuiting is required to prevent the battery from exploding.

Device compatibility: Most devices are compatible with AC/DC power supplies, but not all of them are. The compatibility is mainly affected by the output power, safety circuiting, and bulk charging current.

Charge rate: If the charging current is too high, it will reduce the battery's life. So, we need to choose a safe charging current.
