Lumin L-300 Power Bank (30000mAh / 200W)

Features of Product

Sturdy, Large-Capacity Design with Retractable Cable Built with an aluminum alloy and plastic body, the Lumin L-300 is engineered for people who need serious backup power. Measuring 136×72×51mm, it feels solid in hand and holds up to the demands of travel, work trips, and long days off the grid, with a retractable USB-C cable built right in so there’s one less thing to pack.

30000mAh Six-Cell Battery Six high-grade cylindrical cells (21700) deliver a full 30000mAh of capacity with an 18000mAh rated output, enough to recharge your laptop, phone several times over, plus your earbuds, tablet, and accessories, before you ever need an outlet.

200W Total Output The USB-C port and the built-in retractable USB-C cable each push up to 100W (5V 3A / 9V 3A / 12V 2.9A / 15V 3A / 20V 5A), for 200W combined, enough to fast charge a laptop at full speed. The USB-A port adds 22.5W max (5V 4.5A / 5V 3A / 9V 2A / 12V 1.5A). Powered by the SD59D24B main PCBA IC, output stays fast, stable, and efficient across every device.

QC & PD Support PD fast charging runs through USB-C and the retractable USB-C cable, while QC fast charging is supported on USB-A, so whatever charging standard your device uses, the L-300 is ready for it.

Dual Input, Triple Output Refill through either the USB-C port (5V 3A / 9V 3A / 12V 3A / 15V 2.35A / 20V 5A, 100W max) or the retractable USB-C cable (5V 3A / 9V 3A / 12V 3A / 15V 3A / 20V 3.25A). Power your devices back out through USB-C, the retractable cable, and USB-A, charging three devices at once when you need to.

PD 100W Recharging Despite its 30000mAh capacity, the Lumin L-300 refills in under 1.5 hours with a PD 100W fast charger, a full tank of power, ready before your next trip out the door.

Built-in Digital Display A digital display shows remaining battery as an exact percentage, so you always know where you stand, no guessing from a row of dots.

Ready Out of the Box Every Lumin L-300 ships with a 30cm charging cable included, on top of the retractable cable already built in, so it’s good to go the moment you unbox it.
