Baseus Blade Slim 20,000mAh 100W Power Bank for $39.99
The Baseus Blade is only 0.7 inches thick. Most high capacity batteries are over 1 inch thick. The Iniu has a slimmer body, instead using a wide body design which means it has a more boxy shape and is a square 5 x 5 inches. The form factor allows it to fit perfectly into a laptop bag or backpack. It still weighs about one pound, which is comparable to other power banks, so there's no compromise here.
The wide body allows for four ports: two USB Type-C ports each with an output power of 100 W and two USB Type-A ports each with an output power of 30 W. Please note that the maximum charging power is 100W. This means that although the total power of all three ports is 160W, a maximum of 100W will be transmitted when all three ports are used simultaneously.
