Is there any reason this car charger wouldn't work?

This OEM Motorola micro-USB charger is supposedly rated 4.75-5.25V 950mA. Is there any reason it wouldn't work for the Vibrant for a high-draw situation (in-car display-on with navigation)?

Should work. Some posters say that 1amp is not enough for in car nav and charging. They recommend getting the dealextreme 2amp blackberry charger.

Does anyone know if Dealextreme one ships from US or HK? Just need to determine the shipping time-frame.
Thanks.

everything i have ever bought from dealextreme came from somewhere in china and took ****ING FOREVER.

I use that one - it works. It couldn't keep up with wardrive last night though - drained 3% during a 20 minute drive. Haven't checked the charge current yet, maybe it's not pinned out properly for high-rate charging.

Two meanings -- the app I was using, wardrive and the actual activity -- driving around, logging wifi access points with GPS. Very battery intensive, with the constant GPS updates and wifi scans. Here's the outcome -- https://wigle.net/gps/gps/Map/onlinemap2/
Anyway, probably a good comparison to running Nav and maybe some music at the same time.

Got it, thanks. So you're saying a 950 mA isn't enough.. hmm. I have a power inverter, which has a 5V USB output providing 1A. Wonder if that would be a little better.

I was going to recommend this charger, since when using nav and music at the same time, my battery pretty much stayed the same or gained a few percentage, but now I wouldn't recommend it at all since it started burning today. Just my opinion.
I'm gonna buy this charger from Amazon. It's basically the same one you posted, but from Amazon themselves. Since I got prime membership, might as well buy from them and have a piece of mind sine they got good customer service. Oh, there was one reviewer that had this charger with the Vibrant and said it was good, so yeah.

Why would you buy this charger from Amazon, since it's exactly the same as the one that you already have, which started burning?

I was going to ask the same thing. Not encouraging for me, since I have that charger too... Bought from Amazon of course, but unless the ebay auction was for a fake then it doesn't really matter where it came from.
Anyway, it seems like a decent inexpensive charger to me. I'll have to try nav alone on it next time -- wardriving is very battery intensive, so not really a fair test.

Makes sense now... thanks

Regardless of what these charges are rated, my guess is the phone will pull around 800mA. 1.1A if the phone thinks it's a wall charger.
Open the file /sys/class/power_supply/battery/batt_chg_current with Astro or some other file manager and you'll see the current being pulled.
In the same location, the file charging_source gives the following values:
0 - no power source
1 - usb power source (with limited current per batt_chg_current)
2 - wall power source with higher current in batt_chg_current)
The car chargers I've tried are recognized as USB sources only. Even when taping off the data pins and plugging into a USB port on a computer the phone will still recognize the source as USB. Which means the charge rate is lower, regardless of the charger's rating.

Incompatible charger warning

Just wanting to know if anyone else has run into this issue... I bought a USB car charger on Monoprice before getting the Thunderbolt. When I plus it into my phone however, it won't charge and I receive a pop-up warning about incompatible chargers damaging battery. So, what non-OEM charters tend to work best with HTC phones?

It's hit and miss, but if you get that, don't use the cable/charger. I got that with my INC once when I was using a blackberry micro usb cable to charge. It did horrible and barely charged anything in 30 minutes.

I have a microUSB charger from ATT that I've been for a year or two. Works great with my thunderbolt, though slow. No errors or warnings from it.
It definitely doesn't produce enough power to charger while in hotspot mode.

Your gonna want a charger that charges at a rate of 1000ma or 1A, older chargers for non smart phones and even Blackberry, dont put out that much. My blackberry chargers only put out 700ma. It would charge it, but a lot slower.

Please tell me you at least tried your wife's charger to determine if the one you were using was good or bad

Thanks for that link. I have the Kensington single port 1-amp model of that device in my car. Charges everything just fine.

Car charger?

Picking up my phone on Monday, and was planning on getting the car charger. But before I spent the extra $30 I figured I would ask you guys. Is it just a standard mini USB? (not sure if mini or micro is the right term).
For instance I found one on Amazon (I can't post the link because I've only been a lurker here until this point). It's called "Premium Car Charger For HTC ThunderBolt"
Product Features
Brand New IC Chip Controlled Plug in Car Charger
State of the art Intelligent Chip circuit prevents overcharging
Conveniently charge your HTC ThunderBolt battery while your drive
Non interrupted charging, even while the HTC ThunderBolt is in use
Essential accessory in case of car accident or another emergency
Thanks in advance, I'd just rather not give Verizon any more $$ then I have to

micro usb is what you want (different from mini), and the home charger outputs 5V and 1A (same as
1000 mA) so you want a car charger that will output the same voltage and close to the same amperage. i used a 750mA car charger for my evo and it was a noticeably slower charge.

+1 on the Moto rapid charger. Got one for my DINC and now using it for my TBOLT and that thing is amazing. And cheap!

Thanks guys. Just ordered one for myself.

Again, I can't post links, but I believe this is the one you're talking about. It's listed on Amazon as "Motorola Vehicle Power Adapter mini-USB Rapid Rate Charger" for $9.09?

he is saying delete the http:// part and you can post the rest as text

anyone try one of these with the stock cable? Or with a $1-$2 replacement cable. Or this Micro car charger they sell
I know monoprice has great quality on their items and the output says 5v and max 1A
According to this, they work just fine http://forum.xda-developers.com/showthread.php?t=1001962
So the charger + a 6'+ cable will let you go anywhere in your car and more for a little over $3, prolly 5-6 after shipping.

Thanks for the tip on the charger. I had noticed that my current car charger seemed to be pretty slow. Ordering the Motorola charger now...

Another +1 for the Motorola charger. Its high quality. I have noticed the plug gets a little loose after a lot of use and wont provide a good connection. I just squeeze the Jack a little with some pliers and that tightens up the fit again.

I use one brought.from att and.its speed for charging is pretty.good.

I'm going to go with a tentative yes. Since it has a 12v output, however I'd check out this one:
amazon.ca/Energizer-XP8000-Universal-Adapter-External/dp/B0029U2WZU/ref=sr_1_1?ie=UTF8&qid=1328748112&sr=8-1
People on another forum had a long discussion on the subject and the consensus that was reached was that it was the best off the shelf option.

I don't think you will be able to plug that one into your tablet - the plug for the A100 is a rare one.
Check this discussion for all the gory details:
www.acertabletforum.com/forum/acer-a100-accessories/1404-external-battery-a100-3.html
I finally ordered this one:
http://www.expansys.ca/energizer-xp8000-universal-power-adaptor-221031/
You then have to order the correct adapter (NP12) for free from the manufacturer. It's an excellent product.

When I was at the local Radio Shack they had "G" type(I think it is) connectors that can go onto the ends of the charge adapters they sell. Fry's has the same stuff. Its just the little connector end you attach it to the wire your self. Im guessing as long as you have 12v supply that will deliver around 1.5A and a pos and neg wire you could just one of those. Its the same end as is on the universal car chargers folks are using from Walmart.
I have been wanting to find a small solar pannel or somthing for camping and such.

Hehe no worries man. I didn't think about that or realize it my self until I went to buy an adapter and looked at the specs on the wall charger. I had guessed it would be 5v like most other small portable devices too.

so overall , do we have an external battery charger we could use with this tablet?

As I said in post #3,

It's pricey, but it works well.

Anker Astro 3 battery backup pack
Bought an Anker Astro 3 (10000 mAh battery pack from Amazon (has 9v/12v option) for $59. Bought a special cable for the Anker to Acer Iconia from Edosupply on Ebay for $8.50.
Charges my A500 from <10% to 100% in ~ 100 mins with the switch set to 12v. Nice
The Ebay description says that the cable can be used "for Anker External Battery fit Acer ICONIA Tab A500 A501 A200 A100". Mine works for my A500 so I suppose it should work for the rest?

Confirmed here as well:
http://forum.xda-developers.com/showthread.php?t=1835878

I wanted to share my experience with an external powerbank for the A100.
My main issue was, I need something like the Ankor, but that product wasn't available for me to buy in Australia. Amazon sellers wouldn't ship the item, nor at a reasonable price.
So instead, I bought something similar, which I bought out of China (Ebay). It works perfectly, and the powerbank can be used on other USB charging items which require 2A 5V power (HP Touchpad, etc). Perfect for when we travel with multiple mobile phones, tablets, etc.
For the Powerbank, I bought this: 10000mah Powerbank
For the cable for the A100, I bought this: 2pcs Short DC 5 5x2 1mm Female TO 3 0x1 1mm Cable | eBay
Again, both work perfectly for the A100, and all my other charging needs.

Car charger
I am looking for a way to use it in the car. I first tought on going with 120v converter and use its usual wall charger but i would prefer something more integrated.
I've looked into this:
http://www.amazon.ca/Psa18r-120p-Ad...1394232288&sr=8-6&keywords=iconia+car+charger
But it seems rock cheap and I expect it to either burn or the cable to break easily (looking at it)
Did anyone had any previous experience with Pwr+ products ?

Wall chargers - anything special between different kinds?

My chargers are all ripped somewhere and not charging right so I'm going to buy a new one. Besides the amps, are there any difference between chargers? I was told to order an HP 2.1A off Amazon but my gut tells me to get a Samsung one. So if there's any special or good wall chargers that have the usb cable someone let me know, thanks

better safe than sorry

The little samsung brick is 1amp. You can probably get one for $5.

Is getting a bigger amp one better or will it just overheat the phone?

I was looking for a good charger with a long cable, this one says the cable is pretty short

My suggestion is to buy chargear and long cable separate. I think 6 feet is the longest microusb cable I have seen

Make sure it has data transfer capabilities. Although most do I have gotten one in the past that was a charge only cable.

I've used generic charging cables for YEARS with many different types of cell phones and have never had a problem. I think I had a charging cable fail once, but never any damage to a phone. I always go with the cheapest ones I can find.

I too use generic chargers and cables. As long as the specs of the stock charger are met (voltage and amps), you should be fine. I usually get my gear from monoprice.com. Their stuff is very cheap and I haven't had a problem with it [yet]!
