Pocket-sized charging that doesn't compromise on speed or reach.
A 4,500mAh power bank that fits in your palm and charges your iPhone 15 from dead to 50% in 30 minutes.
At $19.99, this bridges the gap between ultralight and actually useful—small enough to forget you're carrying it, capable enough to save you when your phone hits red.
What we looked at
- 01Capacity & Speed 4,500mAh with 20W fast charging output
The mAh-to-size ratio is the real win here. You get enough juice to meaningfully extend an iPhone's day without the brick-shaped bulk that used to come standard. 20W output means charging happens in real time, not glacial time—the 30-minute 0–50% benchmark is legit.
- 02Form & Function USB-C built-in, lipstick-sized, includes USB-C cable
No separate charging cable to hunt for or lose. The built-in USB-C port means you carry one less thing. It's genuinely pocket-slip small, making it viable for bags, jacket pockets, or gym lockers where a traditional power bank would be a pain.
- 03Device Range iPhone 15/16/17 series, iPad, AirPods, Samsung Galaxy S22+ Pixel, OnePlus, Huawei
The USB-C architecture means it works across the whole modern ecosystem—Apple and Android both. Pass-through charging lets you juice the bank while it tops up your phone, and the 18W recharge rate means it refills reasonably fast.
