Questions and answers
- Which is better for home backup during an outage?
- The EcoFlow, because it can auto-start and be monitored remotely. The FIRMAN needs someone on site to pull the electric start.
- Which has more outlets?
- The FIRMAN, with 4 outlets. The EcoFlow lists 2 USB-C outlets plus DC ports, so check for the AC receptacles you need.
- Which is easier to move?
- The EcoFlow at 83 lbs versus 92 lbs for the FIRMAN. Both are heavy enough to want a second person or a wheel kit.
- Is the EcoFlow worth about $1,200?
- If remote start and app control matter, yes. If you only need basic dual-fuel power, the FIRMAN does the same job with fewer features.
- Which runs longer on a tank?
- The FIRMAN's 1.8-gallon tank is larger than the EcoFlow's 6 L (about 1.6 gal). The EcoFlow claims 8 hours at quarter load on gas.
