One of our favorite power banks is 52 percent off right now

Our pick for the best budget laptop power bank can be yours for $47.59 with the help of our exclusive code.

Thanks to the slim form factor and light weight (it's just over a pound), it's easy to slip into a bag next to your laptop. The power bank has a capacity of 20,000mAh, which is enough to charge a fifth-gen iPad Air 1.5 times over or a 14-inch MacBook Pro to 80 percent, per Baseus. But in terms of bang for your buck, the Baseus Blade isn't bad at all, especially when you factor in the convenience of the slim, 0.7-inch design.
