Portable AC power bank for laptops

This 116Wh unit delivers up to 100W from its AC outlet, letting you run compatible notebooks away from a wall socket. It also supplies 5V/2A over USB-A and 5V/3A over USB-C for phones, tablets and smaller USB gear. A built-in LED flashlight adds a practical light source for travel or emergencies.

Thermal behaviour and power draw

The lithium-ion cells and protection circuitry manage over-charge, over-voltage, over-current and short-circuit events without active cooling. In normal use the bank runs silently because there is no fan, and surface temperature stays modest while delivering 100W AC or the rated USB outputs. Recharging the bank itself uses the USB-C port at 5V/3A, drawing power from a compatible adapter.

Connectors, mounting and daily use

One AC outlet, one USB-A port and one USB-C port cover laptops, phones, cameras and devices such as a Nintendo Switch. The AC outlet requires a three-second press to activate and must be turned off manually to avoid continuous drain. USB-A and USB-C work instantly for smaller gadgets. The black enclosure fits in a briefcase or backpack for mobile professionals who need reliable off-grid power.

Questions about this item

How do I turn on the AC outlet and what step do people forget?

Press and hold the power button for 3 seconds to enable the 100W AC outlet. The step people forget is turning it off again after use, otherwise the battery keeps outputting power and drains faster.

What part will need replacement first with heavy use?

The internal lithium-ion cells will degrade over hundreds of charge cycles. When run-time drops noticeably, the whole power bank must be replaced because the battery is not user-serviceable.

What limit appears first when I run a laptop continuously on the AC outlet?

The 116Wh capacity is the first limit. A 12-inch MacBook draws roughly 1.8 full charges before the power bank itself needs recharging.
