The standout feature here is just how thin this power bank is. It measures only 0.2 inches thick, so it’s slim enough to slide comfortably into a pocket without adding much bulk. This makes it an especially nice companion for ultrathin phones like the new iPhone Duo.
The 5,000-mAh battery is designed for quick top-ups and emergency power rather than multiple full charges, making it ideal for everyday use.
The built-in USB-C cable means you don’t have to remember to pack an extra cord, so you can simply plug in and start charging. It works with the latest iPhone 18, iPhone Duo, Samsung Galaxy, Google Pixel and other USB-C devices.
The power bank also has a premium aluminum finish that feels more like a smartphone accessory than a cheap battery pack. Plus, built-in protections help guard against overheating, overcharging and short circuits, and it’s even flight-friendly for travel.
Alternatives to consider
If you need more than just an emergency phone charger, Anker’s 25,000-mAh laptop power bank is worth a look. It delivers up to 165 watts of total output with three USB-C ports, including 100-watt charging for compatible laptops, and features built-in retractable cables so you don’t have to pack extras. This power bank normally costs $135, but you can save a modest $15 right now, bringing the price down to $120.
