Haven’t had the opportunity to really use it yet, as I bought it to have in case of emergency being here in Florida. May very well need to use it this week as Waiting for Hurricane Milton to roll thru.

Can’t say enough good things about the F3800, will buy a few more. The 400W solar panel works great, but it will barely stand up on its own and I will need to make an A frame stand, or sawhorses. I don’t regret having the 400W for travel use, but would never buy a second one.

I never received my order

I’m just amazed at the power this thing has! I tested it out with a few major household appliances like the full sized fridge and washing machine and it did remarkably well!
Now I’m charging it up for the next power outage.

Build quality is exceptional. Interface is very well done, even without the app but the app certainly adds to it. Ability to wall charge is super convenient and provides a nice level set to compare with solar and allows for quick recharge for storage (at about 85%). At mid day we were at about 265W of charging, compared to 1800W from the wall. Definitely will purchase additional batteries and panels to expand my capacity, but this is a great starter kit. We used it to cook (pressure cooker) for a few hours as a mock power outage test and it worked perfectly.
