They hold 60,000 and 90,000 mAh of power, respectively, so there's a lot of power here, but in a manageable package - they weigh 5.1 and 6.2 pounds, respectively - and both have a comfortable carry handle. The light on the top is one of the best I've seen on a power bank. It's a lantern as opposed to a flashlight, and the built-in bellows-style diffuser does a remarkable job of spreading the light.
