    hello

    Having just repaired two eBay replacement chargers I'm hankering after my original one.

    The only thing stopping me is working out how to get into it without partially destroying the case. Now I have to accept its just scrap taking up space in a draw so I'm going to get the tools out this week and have a look.

    Before I get busy with my arsenal of highly destructive tools, does anyone know how to get the top off without too much damage?

    thanks

    Jon

    Looks to me they are ultrasonically welded, so opening it without damage could be a very tough nut to crack. Normally, what I do with similar gadgets is that I put them into a vice, tighten them until they start to bend, release the tension, then tighten them again in a different position, hoping that eventually the weld will crack. Sometimes this technique works, other times it does not.

    You can also try a heat gun hoping that they used a glue and not ultrasonic welding.

    I managed to open it with a dremel. Its complicated in there, I confirmed the cable and magnetic plug were OK using a continuity test and that the power pack had failed (not sure why at the moment). The cheap ebay power packs work OK but the magnetic plugs are very very poor. So I decided to chop off the cheap mag plug and join it to the original cable and mag plug.

    I now have a fully working charger with a very long cable!

    After opening up two cheap mag plugs I'm surprised they lasted as long as they did.

    Thanks for the help

    My apologies for replying on such an old post but this may come in handy for future readers.

    We just opened up the charger by applying a few atmosphere of compressed air on the USB port (sealing it using a little rubber mat with a hole). The lid blew right off with a loud bang. It was glorious! I'm still laughing.

    This makes for a much cleaner repair than using an angle grinder or a vice.

    Happy holidays!
