Joyroom JR-PBF29 20000mAh Power Bank with Built-In Cable

Never get caught with a dead phone again. The Joyroom JR-PBF29 is a 20000mAh power bank with a built-in cable, designed for people who want fast, reliable charging without digging through a bag for a loose USB cord. It packs a large 20000mAh Li-Polymer cell into a compact 72.9 x 32.5 x 109mm body, so it's easy to slide into a pocket, backpack, or handbag.

With 22.5W maximum output, this Joyroom power bank charges phones noticeably faster than standard 5W or 10W banks, cutting down waiting time whether you're commuting, working from a café, or travelling. The built-in USB-C and Lightning cables mean you can charge an iPhone or an Android device directly, without carrying a separate cable that's easy to lose.

A smart digital display shows the remaining battery percentage in real time, so you always know how much power is left before you head out. Combined with a fireproof ABS + PC shell, the JR-PBF29 is built for everyday, on-the-go reliability.
