Looking for a 12V DC charger at a local store..

Choices aren't great...

Walmart, Staples, Radio Shack, Target....

I bought one at Walmart for all Samsung devices, but it didn't work..

What should I be looking for...

I tried asking one of the Techs at Staples.. Dumb idiot was useless...

Thanks

I bought this pack about 2 years ago. Always give me a full amp charging. You'll need a good usb cable though.

Edit: can't post links, search Walmart Rayovac usb charger.

12vdc charger and a separate household comes in about $12

Appreciate the info...

What is a good usb cable considered...

i bought a 12v Duarcell USB 2.1 Amp today.
It charges my Galaxy S3. but doesn't charge the i717..

I'm starting to wonder if I need a better cable like you are recommending.

I have a couple cables that work with the AC USB adapter and on my computer..

But they will not work with the 2.1 amp DC usb adapter.

I figured the 2.1 amp would be enough.

What should I be looking for Amp/Watt wise in an adapter...

Thanks

delayed response. the good cable i mentioned would be any charging specific cable where the data pins are shorted to force most phones into ac charging, or any cable with a decent gauge wire in it. i ran into a problem with some really cheap cables that were overheating at the pins due to bad solder joints. The phone showed it was charging but the battery would drop unless the screen was off. It took nearly two days to charge with that cable. The cable didnt feel warm at all, but it had too much resistance to carry the current for the phone.
