Is this generator any good? I can get it for 150 euros. The crazy plan is to use it with laptop, printer and heat press(1250 watts) on a pedestrian street.

If not, any budget alternatives?

In case no one has ever told you. You get what you pay for but In this case I would buy as many of these as I can. PF of 2.0 is not something you usually get on cheaper European models.

Pretty good,eh? It's really hard to see experiences about this model, no videos about it and I only managed to see 2 German reviews on Amazon who weren't satisfied 1st malfunctioned, 2nd leaking. But those 2 experiences dont mean these are bad in general.

>>2810094
Loudness could be a deal breaker? I got inspired by people who already did this in touristic areas, I don't recall them being loud. If it's not that, I wouldn't be in the middle of the street but on the side kek

supposedly the ac you get from a cheap generator is dirty and will mess up a laptop. i'm not sure if i believe it or not.

>> No.2810149

>>2810088
If you are gonna use it for more sensitive equipment, like your laptop, you want to make sure you use an inverter generator, otherwise you run a high risk of a power spike frying your shit.
This doesn't look like one, looks more like what you'd use for lights at a construction site or something.
My point is, check out the specs on the model and see what its intended uses are, or simply saving money could lead to having to replace your laptop.

>> No.2810158

So it's risky to power laptops with these kinds of generators. The cheapest Inverters are 400 euros , it's too much of an investment for this idea.

>> No.2810160

>>2810148
They convert the AC output to DC and back to AC to avoid the potential power spikes you can get with the "raw" AC output. Laptops and TVs for example that uses finer tech will be sensitive to those spikes and you will most likely end up with fried circuit boards.

>> No.2810166

I would advice you to get an inverter generator, yes, they do cost a pretty penny, but dead electronics are expensive to replace.
I personally wouldn't take the risk.

>> No.2810167

>>2810160
Inverter ones would solve the noise and damaging issue it seems. But still not investing into them.

I could try charging the laptop at diff places there, without plugging it in the generator. And the generator could handle the printer/heat press

>> No.2810194

Get a solar panel and a couple of car batteries.
No noise, last forever, DC/DC converter from 12 to 21 V (or whatever your laptop needs).

>> No.2810196

It's an interesting idea, but how costly is it?

>> No.2810225

>>2810196
Not costly. You should already have all of this shit for emergencies. Instead of collecting dust, you’ll be using/testing it on a continuous basis.
And when the power fails, you’ll be the guy letting people charge their phones at your stand.

You can get camping solar panels 100-300 watts relatively cheaply. They will be continuously charging however many batteries you want to get.
The batteries can power the heat press, however, ideally you’d want to get a press that
(a) uses a trigger to heat up in a few seconds rather than one designed in the 1950s that is always on.
(b) uses 12 V rather than an inverter.
You might be able to modify the press, you can get heating pads that use 12 V or using nichrome wire or something.
The laptop and printers are no-brainers on battery power, if you can’t figure those out, you shouldn’t proceed. DC/DC converters are essentially free.

Hey little zoomer, compared to how long that generator will last, it might as well be forever.
A car battery can easily last 10 years and can often be found for cheap when replaced in critical systems.
Or, more likely, you’re unaware car batteries can be recharged and don’t know that those small gas motors have a rebuild cycle of about 50 hours (well, good ones, who knows with this thing in OP’s picrel)

>> No.2810322

> heat press is 1250 watts.
Yes, obviously, that amount of current is going to need to come out of the batteries. The solar is for keeping the batteries charged.

A single typical car battery easily supplies twice that for short periods of time. The total capacity of a typical car battery is around 500 Wh. That means going 500 Watts for an hour continuously.
For short times, it can deliver 2500 watts. But, you’re going to be supplying it with 300 watts of incoming solar most of the time, so it will be charging.

This is why I mentioned that you would need a press that gets to heat in a short amount of time, but spends most of it’s time “off”.

So, imagine one that has a trigger on the handle. When you go to press, you insert whatever into the press, pull the trigger on the handle, it heats up in about 5 seconds, pull the handle down, and it does the press. Then you release the trigger on the handle, lift up the press handle, and remove the item.

Does that make sense?

Why would laptop power adapters or just any universal switching supplies be sensitive to generators?
Switching supplies don't really give a damn about what power actually goes in when it's immediately rectified and put in a tank capacitor. They can very well handle shitty power.

Seems like an old talking point when nothing was universal voltage and a 140v surge on a 120v power supply could very much kill.

>camping solar panels
So the 300 Watts solar panels charge the car battery with 300 watts per hour. 1250 Watts heat press would spend 1250 Watts per hour if it was constantly on(it wont be constantly on btw lol)

>> No.2810562

>>2810437
Correct.
If you have a press from a factory, they are constantly on. You are doing intermittent pressing so you’ll have a duty cycle (how much off time vs. How much press time).
One battery has something better than 5 minutes on, to 20 minutes off. It’s better than that because of the solar cells charging while in use.
If need be, acquire an additional battery.
You’re possibly going to be full-charging your batteries from your neighbour’s outlet at night anyway.

Anyway, this is typical calculations the guy who needs to play call of destiny on his xbox over cell data while camping makes.

This is quite interesting stuff, Im actually shifting towards solar now. I can get this working solar for 70 e, 180 watts. Could it work out comboed with car batteries? And how strong do car batteries have to be if it's manageable to use them instead of generator?

The point is
(a) this is all commonly available stuff. It’s a commodity. Camping, backup power, emergencies, etc.
(b) it’s stuff you should probably already have. I have a couple of extra car batteries, and an small solar cell to recharge them. Also, I have acquired a few inverters over the years. I live in a cold climate, so we always have these luggable jump starters in our cars (it’s just a car battery in a case with a handle).

Car batteries are the most economical solution, especially if you have a source of used car batteries that are not completely dead.
