uhm. is there any device that converts that low power (say 60W) into something higher? or would it be more dangerous?

  Watt(energy) = Volts(voltage) * Ampere(current) e.g. USB phone charger rated for 5V/2A = 10W, laptop adapter for 19V/65A = 1.2kW, electric heater rated 110V/15A = 1650W Voltage and current are like height and width of a 2D box named wattage or energy, and you can stretch or shrink the height thus changing width, but not the total area

    Now way a laptop uses 1200W. More like 6.5A -> 120W

      yea, mobile devices are limited by the ammount of thermal energy they can dissipate. most laptop cooling systems top out at around 30W, anything more is peak load or charging. my i7-6600u idles at around 3W

  Sure, a battery does that. You could charge a battery slowly with 60 W for an hour and then discharge it quickly, powering a 1000 W device... but it would run out in a couple minutes.
