One-star rating. The F3800 solar charger drastically underperformed, providing only two hours of power for lights despite using two 408-watt solar panels. It repeatedly entered protection mode at far below its advertised 6000-watt maximum. Furthermore, the solar panels failed entirely to charge the unit; AC power was the only charging option. Customer service was unhelpful and condescending. This product is demonstrably false advertising, and the customer service experience was unacceptable.

There should be different AC charging options like it won't use AC to charge the batteries until the batteries are dead. Also it's really stupid that when you plug it in it shuts half the receptacles off and passes through the other half. And the outlets are too close so you can't use every single outlet. You have to do every other one. And they shouldn't advertise it as a whole house power station when there's not enough battery power in it to last half a day

I am impressed with the build quality. It is working as advertised so far.
Next I will put solar panel charging on it which will give me whole house backup during power outages. It is very quiet and easy to move around as needed inside my garage or house.
I recommend it.

This unit is solid and I trust it to power whatever I need when I need it. Beautifully designed and well built. Gives us piece of mind- to power all that we need in time of need. Very happy with this purchase. You will be too- can’t wait to expand my system with backup batteries and more solar. Don’t hesitate. Buy it.

I’ve primarily been using my f3800 setup to power my home office as I work from home. Only downside is that I don’t have an excuse to miss work when the power goes out. The f3800 can keep my computer and internet modem running for days. I also have medication that has to be kept refrigerated and it’s always a little peace of mind knowing I can also keep my fridge running when the power is out.
