Gadgets and technology

I would like to know what kind of gadgets boardies bring?? I posted in Gerry's thread about packing this question, but thought it might be worthy of its own thread.

I posted a pic of a spotlight I bought instead of using a flashlight or lantern. I have also bought travel speakers to play my tunes alittle louder.

I would like to know if anyone uses any solar powered products or brought any down?? Any feedback?? Like the battery charger, sell charger or any solar stuff.

I have heard about a pitcher of water that cools your water as you pour it out of the pitcher???

Thanks
