5A is a huge amount of current. For anything. We're talking microwave oven or a couple of desktops.
And FWIW, my laptop charger is 2.25A output. There is plenty of room within a 5A envelope for higher current, faster charging battery tech of the future.
- pjc50 7y agoYou cannot run a 700W microwave from a 20V 5A power supply.
- CraigJPerry 7y agoNo idea why you’re being down-voted. There is a fundamental reason why most supplies will prefer to up voltage rather than current to meet power demand and it’s summarised succinctly as I^2*R
- jbarberu 7y ago5A is an amount of current. It's nonsensical to talk about in isolation. I regularly replace 20A fuses (among the smaller ones) in my car. 5A in the US gives you 550W, not enough to power a microwave. In most (if not all?) countries in the EU you get 1150W from that same 5A.
