50000mAh laptop power bank

This 50000mAh (3.7V) / 185Wh power bank is designed for professionals and travellers who need to keep laptops, smartphones and a Nintendo Switch powered away from mains sockets. It delivers enough energy for roughly 2.5 charges of a 65W laptop or 11 to 18 smartphone recharges. The unit is new and ready for immediate use.

Practical limits of the DC and USB interfaces

The DC output supplies 5V, 8.4V, 9V, 12V at up to 3A and 16V (compatible with 16.5V) or 20V (compatible with 19V, 19.5V) at up to 4.7A, covering most laptop charging requirements. Two USB-A ports provide 5V, 9V, 12V at 3A with QC 3.0 support, while the USB-C port offers 5V, 9V, 12V at 3A for MacBook 12" and similar devices. Recharging the bank itself requires a 19V/2A DC input and takes 6 to 8 hours. Pass-through charging is available by holding the button for 2 seconds during recharging.

Build, connectors and daily carry

Measuring 7.6" x 5.9" x 1.1" and weighing 2.55 lb, the bank fits in a briefcase or backpack for outdoor emergencies. Four output ports — one DC, two USB-A and one USB-C — allow simultaneous charging of a laptop, phone, tablet and Switch without cable swapping. The single DC input means you must carry the proprietary 19V/2A charger to replenish the unit, so users relying solely on USB-C PD for recharge will need a separate solution.
