Thats fascinating - makes sense, though. The rectagular case will tend to bulge on the flat sides and change internal volume and thus pressure. Cylindrical cans will maintain a constant volume.
@@trekintosh - for thin-wall rectangular prismatic cells, where the casing itself cannot closely clamp the "plates" together once internal pressures push them apart.

Don't get me wrong: A Marco Reps Video reviewing (yet another) Portable Power Station is a lot better than no Marco Reps video. But let me put it this way: This is not the kind of content that built this channel and it will not keep it alive.
I laughed so much -> when you said -> us keyboard warriors crave the feeling of the adventures of being outdoors so much that we get the solar panel anyway, even though it will sit in the corner until it rots or the house falls down the reason I laughed so much is -> yesterday I ordered a solar panel, with my unit, even though I could not think of any time or any place that I would ever use it that was yesterday
DBS2300 has 3 versions with different voltage ranges. This video shows the US version. US: 120V-(50Hz/60Hz) EU: 230V-(50Hz) JP: 100V~110V-(50Hz/60Hz) You can get more information on their website
Hi I’m unable to work out if this unit will accept a 12v charge via a vehicle fitted with a split relay charger traditionally used to charge a leisure battery from the alternator via the vehicles battery? You can modify the Bluetti charging enhancer to take a scan current from this to achieve high input charging.
That what annoys me most about those Power Stations is that the Solar MPPT Controllers is too puny. For an Off Grid System you still need an separate more beefy MPPT Charge Controller.
I think if you were going to use this in a fixed installation with bigger panels, you could just attach your own charge controller to the DC battery connector. The MPPT in these things is just designed for portable panels like he showed.
They don't. As Marco showed, the connectors use standard 4mm barrel/banana jacks. The external battery connections need to be proprietary to join with the control modules in the (same brand) external packs, and I cannot see why there would ever be a "standard" version of that.
You know, I am an old viewer since the old good days of the toner transfer pcb inside a laser printer , but I still do not understand why wearing gloves until now even there is no toner or transfer in this video 😲 Man how may of those boxes have you collected so far, Germany will connect its power grid to your house after a couple of sponsor videos of those boxes 😆
I assume making it compatible to both 120v and 240v introduces a lot of complexity and/or inefficiency? I have a 230W laptop power supply that says "INPUT: 100-240V ~ 50-60Hz 3.5A", so the technology exists. But that's only 1/10 the power of this, and it isn't straining for efficiency or compactness. It's literally as big as a brick, and it gets quite hot. Thinking about it, I think it would be really interesting to see someone explain how that works!
The inverter then? I don't really know what I'm talking about, but they surely wouldn't make it useless to most of the world, without a really good reason?
For efficiency and safety ratings, there can be a considerable difference in parts. I’m not sure what efficiency they’re claiming on that AC-DC converter, but you would have circuit that works better on one voltage than another if it worked for both. Inductors, capacitors, transformers etc. need to be tuned for their highest efficiency and size. Those wall switchers for your laptop may be 70-80% efficient. In the case of solar charging that’s a pretty considerable loss of energy for a universal circuit.
I believe there is a small inefficiency in making a switch mode do full range. But it's likely to be the additional components needed for making the UPS inverter dual voltage that's driving it. I can't recall seeing a good inverter that's dual voltage.
@@BobHannent not just small difference - all parts have to be higher voltage rated and higher current at the same time. That includes the capacitors on the primary, the transistors and the main transformer. For low power it's quite acceptable, though.
those products may be very nice... buuut... they are pretty much always to expensive. I would still prefer LTO chemistry for stationary use due to longer shelf life.
Honestly, I just use the same old inverters I used to keep in my car on whatever batteries I can get ~12v out of. The only worry is the wave type, and even then, that isnt too much of an issue depending on what is going to be powered. Thanks to the death of the analog generation most of my digital equipment eats the 60hz stepped square wave well enough for the odd luxury device on the odd old ass square wave inverter.... The only thing these things offer is the LiFEPO4 chemistry (which I can just get bare batteries if I really wanted to replace the stack of old flooded and sealed lead acid cells I have laying around), the battery charging and power management (not gonna lie, its pretty damn spiffy to not have to break out the 12v charger or jumper cables to recharge, or have a simple managed solar option), and the monitoring (which, I mean, I know my inverters, I know my batteries, the math is second nature by now.....so, kind if a luxury, but still cool. The option for graphing data is very tempting...). For the price of these things, its just too damn high for me and those who have amassed this kind of equipment over the years. That being said, the technology is still really cool and the more devices using LiFEPO4 the cheaper cells will get. And its nice seeing the different iterations working through what does work, what doesnt, what looks nice at the meeting table, and what real world use dictates is more important. However, there is still a thorn in my craw that most of those boards have a debug port, but they wont give us a damn hard data port! Screw app reliance!!! There is enough crap polluting the various RF spectrums, we dont need to rely on the radio all the damn time! Especially if its not moving. Let us just wire a RPi onto it directly dammit! Oh, and really, for completeness, however slowly, it should totally charge off USB C.🤣
Whats the deal with these power stations? Is the de and for them really that big? At least in Europe where RV camping is not that popular i feel like no one buys them
They are preparing for the apocolype. They face big energy problems since the Russian stuff started... mains electricity is not as reliable as in the USA.
Whats it's EMC performance like (I'm wary of that plastic lid with no screening paint)? One use for such kit is to do EMC measurements in a field far from other interference sources, but it needs to be fairly quiet itself.
It doesn't matter how it was constructed. If it passes EMC testing, then it complies. Note these requirements are different between the USA and the rest of the world.
@@johncoops6897 supposedly. There's a bunch of debate online about this and how much pressure (if any) is required. Hose clamps are an interesting choice when some bolts and plates would do the same job. 💰
Looks great for a beta unit! The 120V is not so much of an issue given most things have universal SMPS at the front of them. I would personally feel a bit safer working with mains inside and outside my test gear if I had freedom voltage instead of 230 of our finest British volts.
if it's universal smps, it'd have a booster for the active power factor correction circuit, bringing to the same voltage as the 230 blighty ones (roughly 400vdc)
Yo, Marco, what is going on here? I always wait in high anticipation for the next video, typically videos that arent about oversized powerbanks. How many have you reviewed and been sponsored with now ? 5-6 ? You have reached the peak interest of powerbanks 4 videos ago for the majority. Please stop this sellout.
What is a "PLUS/MINUS" power supply? Nobody needs that, because that would be already built into whatever the device is that needs it )eg: a power amplifier)
No, watch the video. He even connected his whole lab to the device, then switched the power on and off. He also discussed the blue switching relays that handle the AC in/out.
Why would you choose a $3,300 power station that can provide 4,400 watt hours on one charge when you can get a $2,500 inverter generator that can power your whole house and provide over 35,000 watt hours on one tank of gas? Is it for size? Well you can also get a $620 inverter generator that can provide 4,800 watt hours that weighs 55 lbs vs 54.3 lbs for this power station. That's less than1/5 the price. You Germans are strange.
Not every use case fits a gas generator. There's use cases where you specifically want a buffer because you already have electric energy coming in intermittently, but don't want the hassle of topping up gas regularly. There's indoor applications where you can't have a combustion engine running and no option to place it outside. There's situations where you don't want any noise coming from your power source. There's some general advantages as well. Gas generators are generally higher maintenance for example. Of course when talking about price to inverter output and energy density, there's not even a discussion to be had - but those two metrics are sometimes simply not the highest priority.
the biggest point is that it can be used indoors, and second biggest that you can feed it from a solar set up. you can't really do either with a gas generator. Plus like you mentioned this is far smaller and lighter than an equivalent gas generator.
@@daskadse769 "no option to place it outside", even in a house extra noise late is frowned upon, unless it's large enough so the neightbors won't hear it. Many areas have local laws limiting the noise too.

And the stated input voltage is 220-240V. So I think this video (saying 110V Only) is quite old... did you notice Marco said "...in 2022"?
Your videos are just soo good. Informative, Easy to listen to, relevant and funny. Would you consider doing them more often pleaseee...
There's a good chance the hose clamps are there to give the specified compression for those prismatic cells.
Programmable input charge current limiting should be a feature on *ALL* power systems!
Especially home energy storage systems!
