USB data/charging cables Micro.. are they all the same?

I have two cell phones..
LG Lucid vs840 4G verizon and LG 840G 3G Trackphone (believe ATT)

I was looking on Amazon for USB cables and am confused.. they have some listed as data and some charging and some data/charging. A couple vendors list some with the same product number for both phones, and then other vendors list different product numbers for each phone.

Looking on the internet it says
1) most micro USB cables work on both phones.
2) some cables are charging only and some are data only
3) most cables do both and are dependent on the phones software
to determine if it will charge via USB
4) some chargers say they have "something" so not to overcharge
the phone ... some are cheap and some are expensive that
have this feature..?

I only need a USB to trans back and forth pictures from both phones.
Charging would be nice.

I have a car charger for the Lucid and the end fits the 840G as well as the wall charger and I plugged in the wall charger and it said
charging... so ... I am of the belief that BOTH cells are compatible with the same USB, Wall Carger and Car charger?

Then back to the data/charging USB... pricing is all over the place,
there are some that come with car, wall and USB and the reviews are
pretty good $9. the USB only from $5 to $19. I could use the extra
car charger and wall charger in the RV & not have to carry back & forth.

Help please

  • GrammaDy,

    I am not at all surprised at your confusion....
    Do you Know the difference between a:
    USB - Micro USB Data/Charging cable - 20$us
    USB - Micro USB Data and Charging cable - 5$us???
    (it is 15$us) - cheap shot, but I couldn't pass it up.
    Some cables are more durable than others, but I have not found that to be related to the purchase price in any way.

    They all come from China and are all suspect quality these days, but some people have the gall to charge more.

    The answer is to plug the cable in and if it works, it's the right cable.

    As to USB chargers - do not pay for hype. USB stipulates a 5V+/-0.25V. So, if it looks like a USB port, it should charge what ever is hooked into it.

    I hope this answers your question.

    Oh, before I forget I believe LGs are Android, and if it is, buy FoxFi. That will let you hook the 3G to your laptop (or any computer for that matter) and it is still faster than most of the campground WiFi out there. But, when you do that it may be tempting to try to power the handset from the computer USB. This may be a problem as often the handset needs more power than the computer USB will supply. So, use the WiFi mode and charge the handset from a charger (and watch the battery condition).

  • They are not all the same. Some cables do not have the pins connected correctly or missing for data transfer and charging. Sometimes it will work on one device and not another. Generally, if the cable is listed as charge/data it will do both. I have bought ten dollar micro usb cables at Walmart that are marked charge/data and they have worked for both on all of my devices. The best thing about buying this cable off the shelf at Walmart in the electronics department is that if for some reason it doesn't work, you can bring it back for refund.
