Deal | Lenovo's 20,000mAh 140W laptop power bank is 25% off ($74.99 instead of $99.99)

Last October, Lenovo launched a 20,000 mAh power bank with a max output of 140W. Then in May 2026, Lenovo released a 10,200mAh version with similar features and an integrated wall charger for $99.99. Now, for a limited time, you can purchase the larger 20,000mAh for significantly less than the 10,200mAh model.

Officially called the Lenovo 140W Smart Laptop Power Bank, it has a list price of $99.99 , but a limited time deal has seen the price drop to $74.99 (25% off) on Amazon. For that price, you get a power bank that can fast charge a ThinkBook 16 Gen 8 from empty to 52% in 30 minutes. The power bank can also fast charge other devices including handhelds, phones and tablets.

The Lenovo 140W Smart Laptop Power Bank has a 2.01-inch TFT screen that shows the battery percentage, charging status, voltage, temperature, and the port in use. Users can cycle through the info using the capacitive controls below the screen. It also has a see-through window below the screen that shows some of the internal components.

Another feature of the power bank is that it has a DC power supply mode, and with its digital hybrid technology which uses a digital chip, it can intelligently manage both modes to increase charging speed and charging efficiency.

Featuring three ports (2× Type-C and 1× Type-A), the Lenovo 140W Smart Laptop Power Bank can charge three devices simultaneously. However, the maximum power output for each port will be based on the number of devices connected. Lenovo ships the power bank with a 240W Type-C to Type-C charging cable and a travel pouch. The power bank also has a 2-year warranty.

The power bank has several positive reviews, but it is worth mentioning that it has some heft to it despite its compact design. The power bank itself doesn't charge as fast as it outputs. As seen in the review of the Lenovo Thinkplus FLUXO 140W 20000mAh Power Bank, which is the same power bank but with a different name, it reaches a max of 93W while charging, and a full charge takes almost 90 minutes using a 140W adapter.
