What this means
- The maker's figure. Switchover times are stated by the makers; nobody we know of measures them independently.
- Lower is better for computers. Desktop computers and some medical equipment need a fast switchover.
- Pass-through is not the same thing. Charging while powering a load does not on its own mean an automatic switchover.
