I'm looking to buy a generator for producing electricity to power different things (e.g. a fridge), in a place where there's no electricity. For now, I do not have a fridge but I may have one in the future (it's an example of a device that needs more power).
Currently I'd need electricity to recharge my MacBook Air from time to time (probably once a day or so).
I guess the generator produces more power than my Macbook Air will use. I just assume that the other unused part will be just wasted.
I'm thinking that there should be some kind of batter/power bank which stores (almost) the entire electric engergy produced by a generator and then I can use that power bank for recharging my laptop few times. I have the feeling this would be a little bit more efficient than using the energy produced on the fly.
Is my assumption about the waste correct? What would be the optimal way to charge my laptop having one of these 220V generators which are available in the shops? Do I need a power bank? Something similar would be handy because hearing the generator noise is not a very pleasant feeling I think. What is the name of such a power bank device?
Is there an even better solution for charging devices like a laptop, phone etc. than a 220V generator?
I have no experience in knowing how such generators work, but I have the feeling that my laptop can be charged, but it's going to use just a very small percent of the produced energy. I don't want to waste the gasoline which is used to power the generator.
When referring to a generator, I mean one of these portable gasoline generators. Is there anything better for my case, keeping in mind that maybe later I want to power devices that may need more power?
