Our Take

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, it's positioned as an impulse buy with enterprise-level review volume backing it—not the cheapest, but priced right for the build and compatibility spread.

Who it is forFrequent travelers, remote workers, students in dorms, anyone who wants genuinely pocketable backup power without compromises. Less ideal if you need multi-device simultaneous charging or battery capacity above 5,000mAh.

How We Judged It

What to check before you buy

Capacity & 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.

Form & 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.

Device 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.
