Don't buy that incredibly misleading marketing line. X-Boost does not boost the output. It reduces voltage and only works if the device you're powering will run at lower voltage, and even then, you're simply just running whatever appliance or device at lower output than you would typically, so its performance will likely be crippled if it even works at all.

I don't even know how they get away with marketing that feature, it's basically a full on lie. Maybe they only market it like that on US customer portals since in the US lying to the public is not only permitted but encouraged.

Quote from Xplic1T :
Lots of people in the Costco reviews are saying this gets closer to 600Wh instead of the advertised 768Wh. Wanted another generator to compliment my old GoLabs unit we mainly use for travel and outages. May just bite the bullet since it is Costco and you can always return.
768Wh is from the battery specs. When you run an inverter from that battery, it never runs at 100% efficiency. You get about 80-90% efficiency max. It also needs to power the DC-DC converter to run the USB ports and such. So no, you will NEVER ever get 768Wh in actual real use.

This is a great little unit. I have 5 of them and they are very very reliable with good wifi connections too, so the app works great. But, I will say...turn off the X-Boost feature or you risk frying the inverter as I found out. Thankfully, EcoFlow replaced my damaged units.

Roughly how many watts were you doing before they fried?

Actually it was a laser printer and i think the initial pull is what killed the inverters...but that goes to show they don't have the right fusing or whatever to shut off the inverter when too much power.
