What we love

This LISEN power bank comes in at just half an inch thick while still delivering a full 10,000mAh capacity. It features a built-in braided USB-C cable that also works as a handy lanyard, eliminating the need to carry an extra cord. While it skips wireless charging, it provides dependable wired output up to 22.5W and includes a small display to keep tabs on the remaining battery.

Our precision-crafted, seamless aluminum alloy body makes this external battery one of the smallest 10,000mAh power banks on the market (just 4.3*2.5*0.5 inches). Feels like a single solid piece of metal—smooth, durable, and beautifully minimalist.
Built-In USB-C Cable & 22.5W Fast Charging: Never forget a cable again. This portable charger power bank features an integrated USB-C cord that delivers blazing-fast 22.5W charging—taking your iPhone from 30% to 80% in just 30 minutes. It’s the ultimate portable charger for iPhone, Samsung, Google, and all USB-C devices. No tangled wires, no extra bulk, just pure speed when you need it most.
Charge Two Devices & See Exact Power Left: The additional USB-C port (15W) lets you charge a second device simultaneously—perfect for travel companions or cruise essentials. Plus, the intelligent LED screen displays remaining battery with pinpoint accuracy, so you’re never left guessing if your phone battery charger portable will make it through the day.
10000mAh Capacity—Twice the Power, Half the Size: With 10,000mAh capacity (enough for nearly two full phone charges). It’s the ideal battery bank for iPhone, Android, and more—whether you need a charging bank for daily commutes, a travel charger for vacation, or a reliable external battery power bank for emergencies.
