Zendure Announces "Smaller, Lighter, Quieter" Power Stations

[TheLostSwede]

Zendure has just released their newest power stations, SuperBase 1000M and 600M. The space-saving power stations are smaller and lighter than comparable power supplies and are designed for agile mobile lifestyles as well as spontaneous excursions. The "M Series" power stations use a metal housing to dissipate heat instead of fans. This allows for a smaller product that runs quieter and is less susceptible to dust and water. Without fans, SuperBase 1000M and 600M create a fraction of the noise that traditional power stations produce. The new power stations peak at around 30Db, approximately as quiet as a whisper. The quiet operation makes it an ideal choice for users who hope to sleep near their power stations.

SuperBase 1000M and 600M can be charged from a variety of sources, including the power grid, solar panels or a car's "cigarette lighter" port. This versatility should prove attractive for people who live off the grid or who want to upgrade their home emergency preparedness kits. Zendure's power stations offer pure sine wave AC output and a total of 9 output ports: two 1,000 W AC outputs, a 100 W USB-C PD port, three 12 W USB-A ports, a 126 W "cigarette lighter" output (100 W input), and two 72 W DC outputs. The arrangement of the ports is intended to accommodate a variety of use scenarios, including home emergency preparedness, van-life, camping, parties, and outdoor work around the house.




Zendure is a portable power company with a focus on sustainable energy located in Silicon Valley in the United States and the Guangdong - Hong Kong - Macao Greater Bay Area in China. Since its establishment, Zendure has continuously launched innovative products, made rapid breakthroughs in the core technologies of energy storage and power supplies, and continues to bring pleasant surprises to the user experience. The company recently received a multi-million dollar series-A round of funding through a joint investment from Shanghai GP Capital and YOTRIO group.

Wait a sec,
Quieter?

I thought these were already all totally silent?! I've never used one that wasn't passively cooled.
Perhaps it's only an issue for 110V systems as ~95% of the planet uses 230V.

I dont see any metrics on the 'lighter' part.

When you plug a 1000W power hog into a car lighter socket you can quite well hear it scream. I think they found a way to muffle this bit.

Aye. This is potentially one of those cases where 'electrical noise' and 'audible noise' overlap.
I don't think there's a single high-end GPU that doesn't scream under load, even if it's watercooled. I'd imagine it's similar with these cost-optimized* Power Stations/Solar 'Generators'.

Here's to hoping they 'mitigate' it by better power driving circuitry and better filtering, rather than just potting things in vibration-dampening epoxy.



*Non-derogatory. All consumer products, and many military products *must* be 'cost-optimized'. DIY, Industrial, and Scientific devices usually are 'purpose-optimized', often at great costs, and sometimes gross efficiency losses for endurance and durability.

Seen the title and I thought interesting are they using something other than steel and concrete. Then I seen it wasn’t a hydro power station lol

Hey hey. North America is more than 5%

And we do have 230V also, usually for stuff with more amps like ovens and saunas etc.

US and Canada is a little under 5% of the global population. Do the Mexicans run on 110V too?

Never mind, just looked it up and yes they do. If you add all the little micronations together with North America and also add Brazil because that's definitely not a micronation, I reckon you can have 8% but only if you promise not to use your saunas and ovens

Don't even get me started on that AWG...

And we run 60Hz like the rest of the world should.

60Hz mains power hum in NA is really annoying though.
50Hz is close enough to the edge of human hearing that it's much much quieter. When you don't live with 60Hz mains electricity your whole life, you REALLY notice it when you go somewhere that has it.

Any idea why NA is different to almost everywhere else? The US is a big old country and one of the reasons Europe went with 220V was because Westinghouse/Tesla said it could power longer circuits of streetlamps than the lower voltage. Given how much larger the US is, and that electric street lighting was the first main use for electricity, I'm confused how Edison's short-range 110V standard was ever a thing, and how it's STILL a thing.

Well, I could but I will get a ban...

Its a safety thing. So for single phase residential power, we are actually 230-240V, but we tap the center of the transformer to ground (earth) for those that like earthing terminology better

So for smaller things its 120V and for larger consumers it's 240V. Most of our 120V systems/stuff has dedicated grounds (earths) for GFCI, Arc fault, etc. etc. I am not a sparky, but even talking to Aussie electricians, they say they like it (the NA way) better from a safety perspective.

As for the hum, isn't any, well at least not in my house. Sometimes I get some led bulbs that do but I return that trash. Typically only hear it with large power draws, like outside lines/transformers. You should stand beside a 150 MVA 3-Ph transformer, 80dba hum

The 60hz is more efficient for induction motors and some other devices also, not to mention more rpm. Old days was actually 25Hz!! I'm kinda surprised some even round number like 100Hz wasn't made as some defacto standard??

edit - perhaps the question should be Any idea why everywhere different compared to NA??

 

[Chrispy_]

Ah, interesting - so stuff like mains streetlighting may well be operating on a 240V circuit like the rest of the world, it's just a quirk of domestic wiring in US households?
