JOYROOM JR-L012 Ultra 45W 20000mAh Mini Power Bank with Built-In Cables

The JOYROOM JR-L012 Ultra is a compact 20000mAh power bank built for people who need reliable backup power without carrying extra cables. With 45W fast charging output, it delivers nearly twice the speed of standard 22.5W power banks, so your phone or tablet tops up faster when you're on the move.

Despite packing a full 20000mAh capacity, the JR-L012 Ultra is 12% smaller than its predecessor, making it easy to slip into a bag, backpack, or even a large pocket. Whether you're commuting, traveling, or working long hours away from an outlet, this power bank keeps your devices running without adding bulk.

What sets this JOYROOM power bank apart is its built-in USB-C and Lightning cables, along with a USB-C port and USB-A port, letting you charge up to four devices at once — no searching for a spare cable required.
