I'm interested if shargeek supports power passthrough(basically nas mode or function like solar controller) ? If that is the case it could be super cool to use in in combination with some portable solar power array. In ideal conditions they could supply enough power for this thing for the entirety of the day and then barely survive the night without turning it off. You could also just make something even smaller that the synology NAS. Like why not ? Just make something small and tightly integrated and here you go. Small solar/battery powered NAS with WIFI cellular data that can be put in to a backpack and backed up over the internet. I can imagine some special unicorns that would maybe want something like this. It would also be very cool of grind NAS. There would be some challanges but nothing that cannot be resolved. I know these are very specialized usecases but they are still very cool.
one big power source should be more effitionat then several small brics. That is if you do not have many dc-dc conversions. super interested in your version of it
Excellent presentation. Thank you. In the booming age of Bluetti/Jackery/Pecon/Ecoflow, having lots of AC/DC power on the go is really simple. These devices can power the NAS along with your computer, printer, phone, speakers and a small fridge if you want.
Interesting subject to which I worked on in a previous life. Back than it was a vehicle to be fitted with various cameras and a NVR functionality was required next to some legal requirements which I can't go into here. There weren't rugged NAS available (today they are still rare and sometimes really expensive) so we opted for regular NAS, indeed SSD's (because of moving vehicle), and in the end worked out that using a 12v/24v to mains voltage inverter, indeed also including a UPS, was the most cost-effective & workable solution. The UPS was able to supply the grunt of the powerdraw, and, if needed, shutdown the NAS gracefully, protecting the data and the hardware. I do believe that if you need a "NAS solution" on the go, using SSD's/NVMe's in a (USB?) type-scenario could be a valid alternative solution. Bottom-line; with some creative thinking you can find a solution for pretty much any scenario where you would possibly want/need a NAS (and/or extensive storage solution) IMHO, it is a matter of costs, efforts, effectiveness and how user-friendly a solution can/must be, and finding the right parts/kits that fit your needs...
I use a LiIon power pack to run my laptop. I get about 8-10 hours of software development use when I'm on the road. I keep two of them with me. I use the Voltaic V250
if you are "mobile" you will most likely have some LipoFe4 battery banks either 12/24/48v... you can run it from there... as you rightfully mentioned ... every W counts... hence - SSD only... nwme.. it has additional bonus... size... on the mobile scenario size does matter - every inch counts ;) hence idea of running nas from power bank from my perspective is no go. happy to see a material on POWER!
12 v power is easy for backup power, I had years an 10ah 12v led battery with a charger powering the router and a small server. I used to live in a place with some power outage so it keept the system always up. Having an power bank is maybe better for light weight and easy to charge if you on the go, but if I was in that situation I probably go with 12v lifepo4 battery and carry around an battery charger for that 🤔
I'd prefer to have an ups that runs on batteries and connects to NAS to report the battery life. I use a regular UPS with my 720+ NAS and the whole setup is huge. I want to have a small sized backup power for my small NAS.
The cause of the HDDs not able to spin up is the USB power protocol. Basically, without communication there ist a limit set in the USB protocol. I believe it is 1,5A. So with the 12V the maximum power draw is 18W. If the power draw is higher, the power supply will cut power. There is no difference in using a wall plug, USB power bank or a large capacity power bank as long as you provide the power with USB. Communication: The max. ampere is 1.5A (not sure about that number, maybe only 1A). If the devices talk to each other, then the power draw can be higher - this is to make sure both devices and the cable support the power draw of up to 100W. So basically, to use the power of USB PD, you have to connect a USB device to the charger.
That's quite odd - it showed it as supplying 20v and it should be able to supply some 4amps or so there, so I guess the spike in load to kick up the drives must have been too much for it to handle all at once. I've definitely run my miniPC off USB power banks (an Anker jobby, the 140w one) and it doesn't grumble when it goes from 5-10w idle to a 30w CPU load if I fire up a benchmark. Perhaps it just has more robust power delivery?
Your DC power brick should tell you what your voltage and amperage are. If your brick says 19V at 5A which equates to 95W, then just multiply how long you want it to run. So if you want 1 day of runtime then you would need like a 2.3Kwh battery at 19V to run nonstop for one day.
Maybe a dumb question, but how does the power bank negotiate the PD when you attach a barrel jack to the USB-C connector.? I'm guessing that it doesn't, so can you manually set the delivery voltage on the Shargeek?
@@stclaws9580 Just AC as far as I know, but there are DC to AV inverters. You would have to power that with USB-C. Or design something else. I've seen Ben make many thing portable that were not meant to be.
calling capacity in just "milliamps" and not "milliamp-hours" is about the same, as calling car speed as just "miles" or "kilometers" (instead of miles/h or km/h) - doesn't make much sense
WTF is a KILOMETER !? *ehm* Now let me rephrase it. WTF is a MILLIAMP-HOUR !? Aren't watt-hours basically the best ? There is no need for conversion and if you count for loses like 20%(80% efficient) then you can easily calculate how long something will last. I agree though milliamps are awfull. I hate them and, i do not understand why they are still used besides just people being already used to them.
@@likilike501 "wtf is a milliamp-hour" - it the capacity you can see on battery. yes. watt-hours are the best. yet, milliamp-hours is a still valid expression of capacity for known battery voltage. so your "wtf is" is unwarranted.
@@stclaws9580 I did not mean it in any bad way. I guess it was an attempt but in the end it was a bad joke. "milliamp-hours is a still valid expression of capacity for known battery voltage." that is what i do not like. You need to take voltage in to account too.
Ecofloew river 2 i guess is suitable size of power pack, and almost same price well 220€, should run the thing reliably. But poweratations should imitaze UPS , support USB safe shutdown. I really look forward to this series, especially solar😮😅.
Doesn't that power bank let you set the voltage output by the barrel connector? You should be able to set that to match the NAS input voltage and it should perform much better than relying to USB C.
Chargers are only tested to last a few hours, the time needed to charge a phone. They may quickly wear out if used continously. The hottest resistor is usually placed next to a capacitor, for absolutely no reason.
Using it with HDDs would work if you were using a NAS that accepts 19-20V DC (a 20V PD trigger adapter must be used for this, not the 15V adapter you have), because the USB-PD standard stipulates that the full 100W can only be used at 20V (but 60-100W is only needed to absorb the power peaks when the HDDs spin up). USB PD 3.1 list Volts / Amps (max.) / power (max.) ------------------------------------------------------------ 5V | 3A | 15W 9V | 3A | 27W 15V | 3A | 45W 20V | 3A | 60W 20V | 5A | 100W
