Overview
A 4,500mAh USB-C power bank with a built-in connector that plugs straight into the phone, no separate cable needed, rated for 20W fast charging. It's built for iPhone 15 through 17 and USB-C Android phones like the Galaxy S23 through S25.
At 4,500mAh, it is built for one supplemental charge rather than multiple full cycles, so it fits emergency top-ups better than all-day backup power.
- 4,500mAh built-in USB-C connector
- 20W fast charging, dual USB-C ports
- Compatible with iPhone 15 through 17 and USB-C Android
- Includes USB-C to USB-C cable and manual
Who it's for
Good for people who want a cordless, pocketable emergency charger for travel, commuting, or a night out, especially if they're prone to losing loose cables. Not a fit for anyone who needs to fully recharge a phone more than once away from an outlet.
Pros and cons
- Plugs directly into the phone, no cable needed
- Compact, pocket-sized and lightweight
- 20W fast charging output
- LED indicator dots show remaining charge
- 4,500mAh capacity covers about one phone charge
- Takes a few hours to recharge the bank itself
- No exact percentage readout, just indicator dots
Performance notes
The direct USB-C plug removes the usual charging cable, and the dual USB-C ports support 20W output plus pass-through recharging, so the bank itself tops back up while charging a phone. Small LED dots on the unit show remaining charge in coarse steps rather than a precise percentage.
