📊 User Feedback

1. TechRadar gives it kudos for its ultra-thin profile and travel-ready design, noting the trade-off in capacity and modest charging speed .
2. Reddit users praise its size and build but point out that wireless output drops over time:

“…thinnest magsafe powerbank I’ve seen… downside is that it does not do fast wireless charging – it throttles due to heat so it’s more like a qi1 charger speed.”

1. iPhone users who want a sleek, everyday supplemental battery.
2. Travelers and commuters valuing portability over high capacity.
3. Anyone preferring wireless convenience with occasional wired backup.

⚠️ Considerations

1. Limited total capacity (~1 full top-up for iPhone Pro models).
