While solar power is generated on the veranda, I use it to charge mobile phones and as a PC power source when working from home.
Until now, I've been using the PowerHouse 400, but I felt that there were various functional deficiencies from the beginning, probably because this kind of model was introduced from the beginning.
You can check the status of power generation from the go, and the solar power generation is working without problems (PowerHouse often doesn't generate power unless plugged and unplugged), and it's also good that input and output are clearly separated (PowerHouse shares input/output, so it sometimes flows back from the mobile battery), and it feels like all of these PowerHouse complaints have been resolved.
There's also a 5-year warranty, so I was able to buy it with confidence.
