140W PD3.1 40000mAh Power Bank

This 140W power bank uses Power Delivery 3.1 to fast-charge laptops, tablets and handheld consoles from a single 40000mAh unit. Its 2-in-1 design works as both a portable battery and a desktop charging station for users who need high output away from wall sockets.

Before ordering check your devices

Verify that each device you plan to charge accepts USB Power Delivery at up to 140W so the bank can negotiate its maximum rate. Confirm you have USB-C cables rated for the same power level, because undersized cables will limit the charge speed.

Sustained-load behaviour

The bi-directional distribution design routes excess input power back into the bank while it charges connected gear, keeping the internal cells topped up during long sessions. Automotive-grade cells and nine protection layers maintain stable output without thermal throttling across multiple simultaneous ports.
