Can i use this power bank
: https://www.amazon.de/...07GSRX6TJ/
connect to my laptop for my laptop to have power? Is that possible? How long does it take to wait in the sun? You know what? Does one know this? I do not feel like struggling with electricity all the time.
Solar power is basically weather and season dependent.
And put that thing in the light!
So I think the energy would not be enough.
I have a similar solar panel from ANKER and an ANKER power bank. Also work perfectly, but I think the solar power charges quite slowly.
I have always used a tablet on the road and it was enough if I have the brightness right down. However, one must always say that the use of laptop tablets outdoors is always energy-consuming because of course, in the vicinity of sunshine hardly sees anything on the display. So it's easier to buy huge power banks and load them at home.
Can you forget, that takes days ne plant for 500 euro with tidy watts that could go I look then times.
That might not work, but it does not have to work.

Can you connect it to the laptop?
But load for laptop, so you do not need electricity?
Mechanical engineering? Nice. Is it good? Yes, of course, light is logical. Think about doing that. Mechanical engineering or architect
Below is a video.
I've tried a couple of times to find a solar panel, which is enough to charge a cell phone. Even that is difficult. And a system that can load a laptop costs several hundred euro. I'd rather buy some decent power banks. I have some of anchor. They are absolutely top.
I use this for my MacBook
This "How I know that" always claps itself automatically haha.
so. I'll tell you something about mechanical engineering regarding your topic:
With MB Know How, you would do the following: at a certain time of year in certain locations, the solar energy provides a certain amount of power per area, which can be averaged over the day
(in other words, on an average summer day without clouds, the sun brings an average number you can specify in watts per square meter)
if you then know the area of your power bank's photovoltaic and also the efficiency of this, you can calculate how much power (on average) is delivered from the sun on your power bank on such a day.
With the capacity of your battery aka Power Bank (several 1000 mAh or?) You can then calculate how much elek. Energy (at a certain nominal voltage) these memories can (maximum) so how much energy is needed to fully charge this.
This maximum energy divided by the solar power at your location at your season will give a good estimate for the duration of the charge.
e.g.:
In Düsseldorf, the sun at an altitude of 60 m above sea level delivers an output of 20 W per square meter
The solar surface of your power bank is 5 cm x 5 cm = 25 * 10 ^ -4 sqm, so that's 0.0025 sqm
One watt is 1 joule per second
So the sun delivers 20 W / sqm * 0.0025 sqm = 0.05 W = 0.05 J / s to your power bank - maximum!
The photovoltaic system of the power bank has an efficiency of 50%, so then the real value of the solar power is: 0.05 J / s * 0.5 = 0.025 J / s.
Now to the capacity:
The battery has a capacity of 3000 mAh, that is 3 Ah or 3 * 3600 As = 10800 C.
(read Milli ampere hour, Amperesekunde and Coulomb, but believe that would not be new to you)
anyway. The voltage of your battery aka power bank is 1.2 volts, then the maximum possible stored electrical energy is: 1.2 V * 10800 C = 12960 J.
The time to load that day would then be… (12960 / .025) * (J / (J / s)) = (12960 / .025) * (1 / (1 / s)) = 12960 * 40 * s = 518,400 s = 144 h
oha… Well… Remember, all values are the grossest estimates and totally out of thin air… But to get the exact values you have to do only research, anyone can do that. But to understand the facts, to set up the correct equations, to know the real counterpart and not to lose track of all this but always to know exactly what is the matter, what is feasible and how everything works, that is part of mechanical engineering.
If you like it then you are exactly right. If not, I'd better think twice, it's always possible to create, but if you prefer designing, etc., designer or architect would be the better choice.
I would argue that the high dropout rates only come from the fact that many start studying (for money and prestige etc) without being suitable or least interested
(But you still learn a lot about our technical environment - eg you will not be able to tell you anymore, the burner would have some reason in the e-car - but I need someone who does not want to lay a solar power bank to say - I like the place!)
but it is definitely feasible… Actually, 90% of students are not really fit for it, many give it too, but most still do it, so it should not be an exclusionary criterion, and it's much more scientific than a designer.
hope could help.
