Title: Suitable wall plug > USB for powering a SD USBPRE2?
Post by: ellaguru on May 25, 2016, 03:25:02 PM

i see alot of plugs & cables out there that will obviously hook it all together, but before i blow it up with a cell phone charging cable, is there one out there that powers it properly? 

thanks
chris

According to the specs, you'll want a USB wall wart with 500mA of capacity. If you can find one that's 600mAh then it won't be pushing all-out and might last longer.

Powering

    USB bus powered, soft-start meets USB hot-plugging power requirements (5 V, 100 mA max current drawn during enumeration)
    5 V, 500 mA max current from USB port (USBPre 2 will not function if connected through a passive USB connection or hub)

I can't vouch for the seller or brand, just a quickie web search, but this one puts out a full 1A, that's 1000mA to you & me!
