    Ok well, now I'm going with a different composite converter, cause I'm too strapped for money. So now it's just one converter at .8 amps, and then the tablet. I think I'll be good with one POV.

    LOL - I thought you did mean our POVs were or reckoned... IMO trivial, but thanks for the POL correction. (Especially if anyone took it as being suspect POVs...)


    If the devices need 5V input (as it seems certain they do), then you need a 5V supply.
    Hence DO NOT connect to 12V. Not without a 5V converter in between. (Where's soundman's oft use pic (cartoon??) of the badly wired car about to explode? [I think it was soundman's. Apols if not.])


    So for all 3, you need 2.5A + 7.5A + 0.5A = 10.5A. But keep in mind that for those with batteries, that should be a max draw when the its/their battery is charging (and probably only at the max when the battery is quite discharged).

    Rounding 10.5A down to 10A means 5V x 10A = 50W output. (P=VI)
    [ NOTE: Normally power requirements are rounded UP because you MUST supply the (full) load. But as I wrote, and as per Gefen's "up to 7.5A", that should be a (rare?) maximum. And I know there are 10A 5V supplies. Otherwise the 10.5A supply would be rounded up to whatever was available - probably 15A or 20A. But I could write a lot more on this - my assumptions etc. ]


    Look at Charging multiple high power USB devices without cigarette lighter - at the bottom of p1 Ryven links the MeanWell 5 Volt 10A 50W 5-Pin (~$33). (I still haven't found the one I was looking for which I think was ~$25.)



    PS... Oh - and as per a recent thread, make sure any converter is for auto use - ie, from (say) 8V to 16V etc - NOT a "12V" (to 5V) converter which are intended for 12V rails as found in PCs etc.

    LEGEND!!!
    I have been so thinking of that in another forum!

    I should have remembered it was 2k1Toaster's - there is a certain commonality between Toaster's name and that pic. I wonder if it is because 2k1Toaster
    always gives me a nice warm feeling?

    probably because new toasters don't work as good as the old ones... my latest one only works after threats of large hammers..
