In this episode of DIY or Buy we will be having a closer look at portable power stations. Those are great for all kinds of outdoor camping or if your garage is not connected to the electrical grid,…..like mine. In the video I will show you how a commercial power station works and how we can create a DIY version which is actually a bit cheaper and can output way more power. Let’s get started!

How heavy was the diy compared to the buy version
Why Are you gay
bro, no homo, but you are handsome
I have a similar commercial "solar generator" battery. I know it's probably possible to build something bigger, but I am perfectly happy with mine. My biggest complaint is that there is no way to charge it over USB. I have a little backpacking USB solar panel, and modern USB-C can charge 100Watts, which is about the same as the brick charger that came with the device. Better in/out USB-C-PD would improve the ergonomics more than a bit more power for me. When camping or surviving a short power outage, 100 Wh per night is plenty for lights and phone and whatnot.
Your voice is changed do you have some problem
It looks like you had the same idea as I had few weeks ago. I finished my 1152 Wh powerbank just a week ago and made video about it (in Czech language, my english channel will come soon). I used steel box because of safety and it has various DC outputs (2x 18V, adjustable 80W from lab power supply module, 14V15A, USB QC+PD). 230V inverter can be connected to it via XT60 connectors, both protected and unprotected from over discharge. The total price was 250-300 eur.

I have done a price analysis on building a DIY power wall – and in terms of the price per Kilowatt it is right on par with grid power usage fees! Which begs the question; why aren't more people DIYing their own power security? Great build! The laser labeling is a very nice touch too.
You were creating A.C. in the old video, fine… but your tesla coils were not good, the arcs were too short/ the circuit was too complicated(compared to slayer exiter).
I tried experimenting around with other "bjt" and could reduce the size of the senondry coil to 7cm and diameter 3 inches,wire used about 34 AWG. Primary coil is the breadboard wire, 1 turn. but i got a decent hot arc length of about 1.5 inches and could light up a cfl without being touched to the coil. (atleast better than your part 1 tesla coil).
for that i use mje"3055" NPN transistor, 22 k resistor and 12 v(1A). power supply.
maybe you should try this or use a zvs circuit, the induction heater you made(for primary coil) for a full sine wave A.C. inverter. You might find it interesting.
Make video about emergency led bulb..
I did a similar project and the core components are simple, but with all the safety and monitoring features gets quite complicated!
You are perhaps more of an electrician then a woodworker =)
Free energy is easy, you only need a handful of spinning magnets

Cool
0:06 captions say bear with me
You are certainly having problems with the voiceover due to your throat. Please take care.
You make it look too easy bud lol.
I would just say that the corners should be in an L shape as it helps resist forces and makes it sturdier.
Awesome work man.
Can you please make a video about how we can make a CB radio transceiver?
Why don't you use a 3D printer for the enclosure?
I know that in this case, the enclosure was big, but for other projects you can start printing, before the epectronics and you'll save some time.
Just wondering if you what your reasons are for the wood construction
Hello sir..
Can you make MPPT Solar charge controller…
Very Good…Please revisit the skateboard with more volts!!
Holy shit 1000$ worth power station? Why not just use the regular saw lol
Great vid as always
You should make a video about how to make an inverter.
I thought you were going to make it yourself.
10:12 – when an electric genius does woodworking ❤ love it! XD
Awesome sir
Could you do a video on the benefits of a sine wave inverter, and what can go wrong with an inverter that doesn't have it?
Please do videos on that 2 stroke bike. I have the same one laying around. Its not functional but whatever.
Why do you think, that you should always go for Pure Sinusoidal inverter, and not just square wave one? It doesn't matter for stuff like power supplies or resistive loads, so why would you pay a lot extra for it?
For totally personal reasons i would be really interested in an 12V li-ion motorcycle battery diy or buy
Great video GreatScott. I made my own solar generator which is very portable https://youtu.be/ha0LLZIgadM
Your sound is a bit different.
I guess the DIY BMS would have been a lot cheaper and open source. It would be a fraction of that cause I guess my 48V 16S battery was less than 100€ in total with 16 clients and a monitor and 1 shunt with most solderings done by pcbway or so. Check it out if you need one again: DIY BMS 4.4 Stuart Pittaway
The sources are one github, there is a forum too and he also has a youtube channel covering each step to build and the developing of these boards.
Make a stereo boom box with tda 7294 ic
your voice is so different than before
3:15 1.8A "plenty" haha.
But serious I really miss applocations that allow 4A that my phone uses
That thing looks quite beautiful but I would consider adding a bit of strength to the housing .Even a kick could easily break that 3mm plywood
Always a good day when greatScott! uploads, it's crazy how education like this is free.
Hi! Can you please do a DIY or buy about a car battery booster? With 18650 cells. (Because that's what I have) 🙂
sir, are you ok?
your voice sounds settled down.
and thank you for making this comparison as I always felt commercial versions were under powered and looked cheap.
have a nice day!
If you use the finer metal cutting saw blades on your Jig Saw you would end up with less scattered edges.
Also turn the "Vorschub" down
Awesome project!
I might buy or even build one of those!
Best view i have ever seen !
