Things to Consider
7 considerationsLimited continuous high-wattage capability—plan on 600 W continuous; X-Boost is marketing and not true sustained extra power.
Most reviewersCumbersome outlet layout (two AC outlets face the back), which can tangle cords against walls or tent sides.
Some reviewersExpansion batteries significantly increase total cost, reducing per-Wh value compared with larger single-unit stations.
Some reviewersWeight (~10.4 lb) makes it unsuitable for backpacking or long carries.
