Since I bought mine for about 230 bucks Canadian, it's been my main device charger and it can serve as a UPS.
I decided to buy it after we had a bunch of power outages within a short time span.
It has a 288Wh battery, with an inverter that can deliver 600 Watts of power.
It's mainly used to keep my headphones, Google Pixel and iPad charged up however it can run my PC for a solid 2-3 hours before running out of power.
What do you think about power stations?
I usually look at the warranty period. So far not seen any that would pay for themselves in power saved within their warranty. Even 5 year warranty on some isn't enough, it would take like a decade or more and that assumes the solar panels charge it to 100% every day and you discharge it to 0% every night.
If you are charging it using off peak energy rates you don't need the solar panels but the payback period is even longer because the electricity is only cheaper rather than free.
I want one, but I want it to make sense financially too and so far everything I see costs so much.
It serves more than one purpose for me, so the calculation is a little different. My freezer has about $1200 of meat in it. If the temperature in there gets up over freezing the meat will start thawing and become damaged or spoiled. Saving that meat from being spoiled would save me spending that $1200 all over again.
The solar panel means that even if the whole power system is out for multiple days I should be able to keep my freezer below zero and keep my meat frozen. Last year we had snow, for the first time here since the early 90s, and it took down power lines on the other side of town. People there were without power for as much as 4 days, which obviously would be enough to heat my meat back up and ruin it, so it isn't a ridiculous possibility.
Also, I intend to make something larger over time on a trailer which I can move from house to house as I move, being a renter. I want independent power and learning a little with this system is a good stepping stone to building out my own system with much more custom parts, especially including a larger battery system, inverter, and more panels. I plan to run as much as possible from the DC to skip inverter losses, so using cheap modules to pull from the 24-48V system I build to do USB C ports with 100W+ output gives a lot of options, along with using smaller dedicated inverters for required loads like a kettle.
The coolest thing is the fully DC power supplies for a PC. You can run directly from a battery and solar system with just 12V, 5V, 3.3V, and a few little bits and bobs. Very fun stuff.
