Limits and cautions
- At about 476 g it is heavy for a pocket. It delivers roughly one useful laptop top-up, not a working day.
- Output drops from 100 W to 65 W at about a third remaining. Check your laptop charger rating.
- The included cable rating was not confirmed; a 5 A USB-C cable is needed for 100 W.
- Elara showed only one unit available to ship when checked.
