This slim-and-fast 20K laptop power bank is a whopping 52% off today

The best way to ensure your laptop never dies on you—whether you’re working at a cafe or chilling by the pool on a sunbed—is to have a reliable portable laptop charger on hand.

I’m talking about something like this Baseus Blade power bank that’s now $48 on Amazon (was $100). To score this amazing price, make sure you clip the on-page coupon to get 45% off, then tack on an additional 7% off with promo code 6QLYR8CY at checkout.

With a high capacity of 20,000mAh, the Baseus Blade has enough juice to fully recharge most laptops from dead to full in one go, while remaining within the TSA’s maximum limit for portable chargers. And with 100W of charging power, you’ll be charged and ready to go within minutes rather than hours.

The Baseus Blade gets its name from its physical design and shape: wide and flat, unlike other power banks that are more chunky and blocky. Measuring just 0.7 inches thick and weighing a smidge over 1 pound, it’s the perfect companion because it can slip into any bag right next to your laptop and you won’t notice the extra weight at all. (If you’d prefer a more traditionally shaped power bank that fits in your palm, the 45W Baseus Picogo is on sale for $18 with promo code.)

Of course, you can use the Baseus Blade with more than just your laptop, including your phone, tablet, handheld gaming console, earbuds, and so on. It has two USB-C and two USB-A ports, allowing you to recharge up to four devices simultaneously (with the 100W of charging power being split up being them when multiple ports are being used). The small digital display lets you know exactly how much power you still have remaining and how long it’ll take to reach full charge on your device(s).

I have the second Baseus Blade 2 and I absolutely love how thin and light it is, but it has less power so charging takes longer. With the original Blade on sale for just $48, this is a deal you don’t want to miss. Don’t forget to clip the coupon and use code 6QLYR8CY at checkout!
