Ranked #5 based on expert reviews, user sentiment, and value analysis.
Pros
- Transparent design with IPS display
- 100W USB-C PD output

Good
Consensus
Compare
Ranked #6 based on expert reviews, user sentiment, and value analysis.
Pros

- Mophie's 2-year warranty is longer than most competitors
Cons
- Maximum output is only 18W — not suitable for laptop charging

- Costs more than Anker for equivalent capacity with lower output wattage
Don't buy this if…
- 18W maximum output will slow-charge modern fast-charge phones — not suitable for 45W+ fast charging
