I had several small cheap inverters but I needed a good inverter to power the multi cooker with a 50Ah 16.5V LiFePo4 battery. Most inverters cut off at 15V, so don't work, this one works in the range of 9.5-17V, wide input range, with 120VAC PSW output, can easily handle the multi cooker. Features like remote on/off, phone adjustment via a module, ECO mode where it detects the load and switches on and off when needed and consumes only 1W are exactly what you will find in high-end inverters . It's a little bigger and heavier than I need but that's just a testament to the quality craftsmanship, Victron makes some of the best inverters and controllers and it shows!
