Great replies all!! Thanks . .
Yes, phone, bluetooth and tablet have USB ports - though it seems to take much longer.
As for DC laptop charger . . Huh!! I had looked for one a few months ago - for my older HP laptop and got 0 results!! And I tried every possible search I could think of . . hmmmm where was this hiding?? Thanks for the link! I had actually called HP and was told that they did not make a dc power cord for my laptop - although they made them for other models - typical!
Guess I just need another 12v usb device so I can charge 2 items at once (of the smaller stuff).
Appreciate your help. I don't know what a "buck" converter is . but will look for one on Amazon.

You buy the items I showed you and you will not have a "need" for any "buck" converters.. The devices I linked DO the "work" for you without you needing to design and build your own power supplies.
As I mentioned, for the Cellphones, tablet devices you NEED to make sure the 12V cig charger IS rated at least 2.4A PER PORT.
Many cheaper ones will only have 1.1A or one 1.1A and one 2.4A ports, 1.1A amp USB ports will take forever to charge.
If you really dig around there are some USB chargers which have 3A or a bit more available those may be of interest to you to maximize the speed your devices recharge.
