DSME’s prototype exoskeleton (pictured above) weighs 28 kilograms, but it’s entirely self-supporting (the exoskeleton includes a frame that extends to the ground), meaning that the human inside it doesn’t feel any of that weight.
Electric and hydraulic actuators, all powered by a three-hour battery, enable its wearer to walk normally while assisting with up to 30 kg of lifting force. So, you’d be able to lift 30 kg like it was nothing, or 50 kg like it only weighed 20. The exoskeleton can also be outfitted with accessories that can turn it into a walking human crane like in the pic (note the chain link attached to the metal part the man is carrying).
