    a good battery for a firewire repeater...

    My Macbook pro being out of order, i need to buy a new laptop !
    Apple stopped the Macbook pro 15" 2,6 with 1 Go RAM...
    So, i'm considering buying a retina... but before, i have to make shure that i will be able to shoot with my Leaf Aptus II7 with it...

    The firewire/thunderbolt adapter can't provide enought power... so you need to use a powered repeater...

    i've bought a really good quality one... Unibrain

    No, i need a good battery pack for it... price are from 10 euros to 800 !

    Any suggestion for the good value for money battery pack ?
    i'm in france, so 220V !

    Thanks


    DC Power connector: Walkman-type 2.0 mm DC
    Power Input Range: DC 8V~30V, max. 1.35A.
    Power Consumption (at 12V DC): 1.5W max.

    FireRepeater-800 Pro: Four and Five ports industrial 1394b (Firewire-800) Repeaters

    Toms Hardware reviewed batteries here:

    Tekkeon myPower ALL Plus MP3750, MP3450, MP3450i : External Battery Roundup: Stay Away From The Wall Socket

    I used the Tekkeon for you desired hub power...for the H3D II 39 back...but I am unable to ascertain if its power supply for charging is still universal, although I do think so.

    BH Photo carries a number of the Tekkeon batteries.

    I can recommend Mili products- am using a power adapter for my iPhone (3000mAh) from them for 2 years now.

    I use this one: Energizer® XP18000 Portable Charger for Laptops | External Battery | Portable Charger and it works fine. There's a 19v output (for laptops) that would be required for the firewire (which is 16 to 30v IIRC). Mine is 220/240v

    it looks like, they are working on it... but apple...

    i'm an apple user till 1996, it was a good ideology at the start...
    the computer needs to adapt itself to the user...
    now, the only ideology seems to be... the user is a consumer, how can we force him to buy only apple product$...

    Yes it will work in that range.

    Regarding the macbook connector, the shop in HK had them here quite cheap, but since I upgraded to an air the adapter changed and now I haven't been able to get one again!!

    If I find them I can let you know.

    It works for me! You need to keep a battery in the back though, but I've used it for hours with no problems.

    with aptus and aptus II you CAN'T use a battery in the back while a firewire cable is connected !

    Here is an other challenger...

    CAlumet powerblock 900...

    it looks like, it is compatible with the Quantum SD16 cable.

    Do you think it will works with the repeater ? and with a leaf back using the leaf plug ?

    the powerblock is only 2000mAh...

    Oh yes, it's been a while since I switched from the leaf, it has that plastic plate you put in place of the battery.

    So I'm powering an IQ back but also using a powered cable not a firewire hub. Basically what I have is a small circuit board that is permanently attached to the end of the cable, there are two are firewire IO ports the other is DC power.

    If your hub can already power the back (using the DC output) all you need is a battery that can match that output. You could go to a specialist RC shop and get a lithium battery, these guys push the boundaries of their batteries and should be able to offer advice. You could also check a resource like this. They should also be able to advise on getting the certificate for aeroplane travel.

    "You could go to a specialist RC shop and get a lithium battery, these guys push the boundaries of their batteries and should be able to offer advice."

    this isn't an option over here !
    i've tried many times... without success ;-(
    i think i will try the energizer first, if it doesn't work, i will keep it for iphones...
    The safe way, seems to be a quantum Turbo 3... but really expensive over here... 700€ !
