Going slowly up a hill even quite a strong push doesn't cost much power. A 200W "push" at 10kph will take you up most road hills with little to no pedalling, ...

As others has said P = F X V Lets say it felt 10 KG - under the force of gravity that is 98 newtons - lets just round up to to 100 N Let say you were doing 15 kmh 100 N 15 km/h * 1 h/3600 sec * 1000/1k = 100 * 15 / 3.6 = 41.67 watts If if felt like about 10 KG and you were doing 15 kmh then about 40 watts Something like Gruber power assist is ...
