I have the power rocks from HSN and love it and it works very well and I can't see any down side to it so far. My friend has similar from QVC and she let me borrow it and I was sold. I just got a smart phone for the first time and am going out of town for a wedding so I figure it will be a long night and if my phone needs charging because I may take a lot of photos on it then I am set to go. My cell is my main phone as I don't have a home phone. Mine came with a car charger too but a cell phone charger for the car will do the same because there is a mini USB port on it besides the regular USB port for the computer. I have one of those USB things that plug into an electrical outlet if I don't want to charge this via the computer. I forget the name of it but it's a square plug that has a usb port in it so you plug the usb cable into it then plug into the wall then attach the mini end of the USB cable to the mini usb port on your device.

We bought our GPS three years ago when we were going to Missouri to see my son and then to Buffalo to husband's sister and his home town. We named ours not very long into our trip. She is Jila. Jila was a little Asian girl who came to my class in pre-school. She was very quiet and shy. For about two weeks. When we went out onto the playground, we wouldn't be out there for longer than five minutes and a child would come up and tell us that " Jila is bossin' us again!"

GPS is just as good as the person who sets it. heehee. We just came back from a trip that took us 2 hrs more then it should have because i put the wrong address in GPS. We still love our GPS. It was great to find our way back even after my mistake. Hurry for GPS.

Some of you have some misinformation, or at least let me say, my understandings differ on a few points: Realtime traffic updates like Google maps/Waze? My portable Garmin has that, so too the built-in GPS units in our 3 cars. Rerouting to avoid problems? Ditto Info sources for traffic? In California, sensors in the pavement provide car speeds to Caltrans and other authorities and I believe this information is passed along to a number of companies, including Google/Waze. That same information finds its way to Garmin and the built in units in my cars just like Google maps. Same info, same ultimate sources. "Crowd sourced information?" Meh, I find it less accurate. No need to have millennials (driving and using their phones) telling me "Oh no, mommy didn't say there would be cars ahead of me that would slow me down. What do I do now, she's not answering her phone?". Navigating where there's no cell signal? Here's where built ins and Garmin type devices excel because they don't rely on having a cell signal to function. An example, I've driven into and out of Death Valley a couple of times - >100 miles of no cell coverage but the built in GPS functions completely normally. No traffic data is received but Hey, there's no traffic in such desolate places. For those of you who want to use Google maps but drive regularly in places where there's no cell signal, you can put the map app into what it calls Wifi mode. Download maps for the areas you'll be driving in while connected to Wifi, then Google maps will work normally (though with no traffic signal) using the downloaded map data. I've done it, it works fine. Or, as above, get a Garmin or a car with a built in.
