Power Your Laptop Anywhere. 310W Total, 20,000mAh.

A power bank built for laptops, not just phones. With two USB C ports rated up to 140W each, a USB A port, up to 310W of total output, and a 20,000mAh (74Wh) battery, it can keep a laptop, a phone, and more charged on the move. A color display shows the battery and power for each port, and a USB C cable is included.

How does it work? +

The power bank has two USB C ports and one USB A port. According to the supplier, each USB C port supports up to 140W and the total output is up to 310W, so you can charge a laptop, a phone, and another device together.

To recharge, connect a compatible USB C charger to either USB C port, which accepts up to 140W input. The supplier states one port can fully recharge it in under an hour, and using both reaches up to 180W. The color display shows the battery, the input and output power, and the status of each port, and built in temperature monitoring and protections help keep charging stable.

Where can I use it? +

Great for remote work, travel, flights, commutes, and long days away from an outlet, anywhere you need to keep a laptop and a phone charged. It also works for tablets and other USB devices.

At 74Wh, it is under the 100Wh limit that most airlines allow, so it can go in your carry on bag. Check your airline's rules before you fly.

How do I use it? +

Step 1: Charge the power bank before your first use, with the included USB C cable and a compatible USB C charger.
Step 2: Connect your laptop to a USB C port with a cable rated for its power needs.
Step 3: Connect a phone or smaller device to the other USB C port or the USB A port.
Step 4: Watch the color display for the remaining battery and the power at each port.
Step 5: Recharge the power bank through either USB C port when it runs low.

For air travel, pack the power bank in your carry on bag, never in checked luggage.
