    We've all been there. Summers around the corner and at the beach or the park you want some decent tunes, without bringing a backpack full of batteries.

    Any portable stereo/sound solutions for this kind of thing? You'd want something like 3 hours playback I guess, with decent sound.

    Can anyone help?

    It's probably not loud enough, but my Logitech MM-50 has a built-in rechargeable battery:

    Don't think you'll be able to avoid the back pack of batteries. The Ipod Speaker thing from apple goes damn hard, also costs a damn lot and will chew through 8 D cell batteries.

    Obviously this wouldn't work at the park with a bunch of people but I've got some Creative Popz speakers that i got from work for free, plug them into my Creative Zen and they go damn loud for what they are (unpowered speakers with drivers the size of a 50 cent piece) Good bass and clarity, if you are sitting around out the back having a few quiet beers with mates they are brilliant. I know they don't look like much but give them a go because they really surprised me.

    Sonic Impact Class-T amp?
    I think it gets 2x8w off batteries.

    This project pops into my head every summer... Team up a small chip amp with some effecient full range fostex drivers or something and i reckon could get a ghetto blaster solution that actually sounds pretty damn good.

    I was thinking a sealed lead acid battery, but someone once mentioned on here they can be rather 'noisy'. Not sure how much of an issue it would be though in this situation. If you could base it on a 12V design too, it could be charged/run off the cigarette lighter too if the batteries are drained and the car is nearby.

    When I was younger thought a car headunit teamed with a 12V battery could also do the job all-in-one too, now I'm not so sure. May not be terribly effecient.

    Yeh I've been thinking of going the t-amp route for a while now. Problem is I just can't find any cheap efficient speakers/drivers. Almost considering buying some car speakers just so I can get it built. Anyone know whether the t amp could power something like this? There are efficient enough, just have a feeling the little t amp might struggle a bit....

    I know ;) , but I just wish we could get something similar to what is available on parts express. A $30-40 full range driver etc...options seem really limited here...

    Been seriously contemplating the fosteks, but it has been said on diyaudio that they wouldn't be too durable in a portable speaker system. Would prefer to get something cheaper for my first system and perhaps upgrade to the nicer fosteks later.

    What do people think of a jaycar woofer/pa tweeter combo? Or any recommended car speakers?

    my old school grounds were just a big park, a few of us would bring our sets of battery powered pc speakers.
    it wasnt elegant but 3 or 4 sets of pc speakers would provide us with music while we played in the park.

    Heh! I remember years ago I made an LM380N amp and put it in a plastic take-away container. Ran off a 9V, ganged-pot for volume, sweet! Put that, some old Sanyo box car speakers I had and my CD walkman on my school bag...

    It rocked! Battery would last about 4 hours, was plenty loud, and gave us something to do at those stupid school athletics carnivals...
