Pros and cons
Pros
- 800 W AC output from three outlets.
- Fast-charge button takes it to full in about 2.5 hours, per the manual.
- Its manual lists ETL certification.
Cons
- NMC battery rated for only 500 cycles to 80%; most rivals use LiFePO4 rated for 3,000 or more.
- 2-year warranty, against 5 years for most rivals.
- Delivered 81% of rated capacity in CNET's test, below the 86% median.
- No battery backup (UPS) mode, no app, and no US store price we could check.
Who it's for
Buyers who find it at a good price from a retailer and only need occasional backup power.
Who should skip it
Skip it if you'll use it often. A LiFePO4 unit will last several times as many charge cycles.
