    SBT Power

    (1) Power
    https://www.amazon.co.uk/s/ref=nb_sb...=297O0WYG2KN5E I use a 16.75Ah RAVPower
    +
    http://www.ebay.co.uk/itm/161886488395 (USB to coaxial power connector) £1.09

    Perhaps made more sense since I've been able to arrange the hi-fi on its own mains ring - I also use optical out since my DAC doesn't have galvanic isolation. ISTM this is optimal isolation of the transport.

    Edit:

    There are various alternative lithium ion batteries that are similar, please search first.

    (2) I also recommend the following apps (Apps Gallery from SBT touch screen). Battery life seems to be much better. It's a reasonable assumption that noise is lowered too.
    - Enhanced Digital Output (disables analogue out)
    - Display Off (then configure system screen saver to use the new option, setting time out to 10 seconds, also see http://forums.slimdevices.com/showth...473#post872473)

    Most of these things can be left charging while you draw power off them too. More UPS than battery. Also means you don't have to turn off to charge.

    Some do but check for it before buying.
    I just bought a power bank for a RPi-based radio I built and I had to buy one that was completely oversized (10,800 mAh which gives me around 24h of operation with that device) one because that was the only on that would turn on automatically, allow operation while charging and had two outputs.
    There's a lot of cheap crap out there.

    True but I've not found any that quote this capability in their feature lists, yet I have about four or five cheap, probably crap, battery units that will all work just fine this way, and I use them on a bunch of rPis too.

    I think it mainly depends on the size. The big ones (10Ah and more) usually can do it, smaller ones often can't. It's probably because the smaller ones have simpler charging logic.
    But I've explicitly come across several that were not able to charge and operate at the same time while I was searching and that was only a few weeks ago, even big ones.

    None of mine are greater than about 5Ah, so even that rule does not seem to apply here...!

    How yer doin buddy?

    Have a read through this

    http://blog.ravpower.com/2017/10/dan...for-batteries/

    You need the highest amps at 5volt for the output, but the output figure is often the sum total of all the outputs (I would guess that a min of 2 or 2.5 on one output, is enough for the SBT).

    Hope you are well

    The power bank from RS you found in the other thread claims to supply 2.1 Amps. If one output draws 2.1 Amps the other output cannot be used. It should be sufficient from the info in the installation document.
