I built this system for my Pool equipment and BBQ plugs. Its a small 4kw system that has a battery. Have an electric hot tub that the battery keeps running over night. It pretty much covers the equipment use year round. Since rate the store is currently not working when the store is not listed. I did purchase the inverter from Portable Sun LLC

Full review / responsesWe purchased this power station to act as a temporary power situation for our RV travels around-the-world. We chose this one because of the Prime day sale and because it was the cheapest option that included a TT-30 port. It has been extremely handy for us and with all of our devices plugged in it lasts a REALLY long time. We are also able to charge it up extremely quickly with our gas / propane generator (in a matter of 30 minutes or so from 40% to full). I would definitely recommend it (so far) to anyone and everyone looking for a powerful, but cheaper and lighter weight power station.
