As summer gets hotter, I am using my air conditioner more often and my electric bill is going up. My house is quite old and I rely on several of the best smart air conditioners to keep my home cool, but despite their efficiency, I still pay more for electricity during the summer months.

This summer, I'm hooking up my air conditioner to an Anker Solix F3800 portable power station and charging it with a solar panel; the F3800 normally costs $3,999, but on Anker's Prime Day it's available for $2,599.

In addition to simply being off the power grid, portable power stations can also serve as a backup in the event of a power outage due to extreme weather. In fact, some editors survived Hurricane Beryl thanks to portable power stations. They are useful not only in disasters, but also when you are camping or RVing and need to get power while off the grid.

These power stations are not cheap, however, which is why Prime Day is a great time to pick one up. Here are 9 of the best portable power station deals we found on Prime Day.
