Would the Teradak X1 8.5V DC out power a SOTM usb card properly? Looks like the cable included with it will fit the SOTM, and the voltage is right in the range of the SOTM. I'm not sure about the amps since the SOTM specs aren't really clear. Has anyone tried it with the SOTM or have an opinion if it should work?

Does anyone know somewhere a linear PSU rated at 5V 2A with a USB connector?

 

By the way, currently I am powering OS SSD with a power bank as instructed by this topic and find it some useful to plug a Audioquest Jitterbug between the power bank and USB cable.

Thanks Rikhav. Are you sure the usb provide 2A current?

 

 

Sorry for the error

Actually it outputs only 1 A of current. But if you can power your hdds with some other source, the 1 A of curent will suffice for the raspberry pi

I have raspberry pi + Wi-Fi adapter + hifiberry digi + board and it works smoothly with the said terdak psu

I just got bought an Anker 2nd Gen E5 to power my SSD. I have a Seagate 600 512GB SSD, and the E5 smart IQ port does not want to rev up its current to high enough level to power up my SSD. The SSD powers up when I plug in my iphone into the second smart IQ port, so the E5 seems to increase its current output on both ports when an iphone is plugged in.

I'm wondering if there is a way to force the smart IQ port to always output 1A? I have tried shorting the D+/D- data pins on the battery, or adding 10kohm/33kohm to supply 1.2V to D+/D- of the battery, but that does not work either. I cannot get the smart IQ port to supply higher current to properly power my SSD by itself.

You could try connecting something like a 47 ohm PW5 resistor across it's output to see if that helps.

That's an additional 100mA current draw on the supply.

I tried 47 ohm resistor between the 5v and ground on the battery output, and that didn't provide enough current to the ssd either. Then I tried it with a 10ohm resistor. That worked and the ssd is recognized. However it seems to heat up the resistor really fast! I had to disconnect the cable before it burns out. So it looks like the 2nd gen battery current is controlled by demand and not by D+/D- voltage.

I wished I got the 1st gen with dumb ports, that would've solved all my problems. But the 2nd gen E5 was on sale at newegg last week for $15 after rebate.

Did you use a 10 ohm PW5 ( 5 watt) resistor? At 5V it will dissipate 2.5W in heat,(500mA) but that is well within the ratings of a PW5 resistor. Just ensure that it has relatively long leads and plenty of air circulation around it.

It is also possible that a 20 ohm PW5 resistor will do the trick. If you have 2 x 10 ohm resistors you could try them in series across the output.

Alex

 

P.S.

You may be able to disconnect the load resistors after the SSD is recognised.

Just got to know that my DAC does not use 5v line from PC'usb, hence my Schiit Wyrd make no sense in usb "decrapifier". So I use Wyrd to power the OS SSD instead of a power bank (because Wyrd provides 0.5 A linear current). The result is considerable, bigger than things happen when I change a 200$ pair of interconnect cable to a 500 $ one in the same system.

Very interesting. So, 0.5A was enough for your SSD? Which SSD do you use as your OS SSD? Can you describe the SQ difference between using a battery pack and linear PSU like Wyrd? What battery pack did you try before using the Wyrd?

I think 0.5 A is more than enough. My SSD is a 128Gb Sandisk.

...

In same boat here.

I've got a 2nd USB disk to give the battery enough load so that it stays alive for the SSD.

if there's a more elegant solution or a currently available powerbank that is more suitable would love to know.

What "batteries' are people using these days to power SSDs? I really like the concept of the Bakoon battery which can be plugged in all the time but it is discontinued. I became tired of constantly having to recharge the Anker batteries. Is there a product that works like the Bakoon and others have tried?

I gave up on batteries.

Got a Uptone JS-2 - one out powers the mobo and the other powers the SSD.

Lifepo A123 directly powering a Compact flash card to SATA adapter with another separate Lifepo A123 powering an upgraded oscillator on the SATA adapter board is the best sound I've managed. I've not tried an LPS-1 or seen the circuit board so cannot comment. The bakoon sounds good (not as good as above though) but the circuit design requires the inclusion of various components between the battery's output and the load. The lifepo solution described above maintains a direct connection from cell to load with the low impedance etc benefits that this brings.

 

If you are interested in a bakoon I have one that I am currently not using and I might be persuaded to part with it ;-)
