article - Baseus Blade HD Laptop Power Bank review: Flat-out impressive

At first glance, the Baseus Blade HD Laptop Power Bank 100W 20000mAh is the ideal laptop power bank. It’s flat, not too heavy, has enough capacity for one charge, and it’s not too slow when charging.

It does have impressive features: a capacity of 20,000 mAh; two USB-C power delivery ports with a maximum output power of 100 watts and an input power of 65 watts; and two USB-A ports with a maximum of 30 watts. It measures 5.27 by 5.27 by 0.7 inches (13.4 by 13.4 by 1.8 centimeters) and is flat with rounded corners, perfect for stowing in a bag. It also comes with a protective storage bag and a USB-C charging cable.

The 20,000 mAh capacity is enough to charge a 13-inch MacBook Air M1 from zero to 100 percent once, with about 5 percent remaining on the Blade HD. During a 30-minute charging session, the Blade HD added 37 percent to an M1 MacBook Air’s battery, 57 percent to the iPhone 15, and 30 percent to the iPad Pro. It’s one of the fastest power banks we’ve tested. The Blade also recharges very quickly. it reaches 90 percent after just 90 minutes and is fully charged after just under two hours.

The display on the top of the Blade HD is very practical. It provides information about the capacity percentage, voltage, and current, as well as the approximate time for the charging process. The major criticism is the poor readability of the display. It is far too dark and can only be read when there is no light on it. Also, the practical benefit of the display would be even greater if the power was displayed in watts and not in a combination of volts and amps.
