While you might be able to do that, I don't recommend it. If you do it anyway, do yourself a favor and NEVER EVER EVER leave it plugged in while you are starting the car.

From Wikipedia:

A second problem is that nominally "Twelve-Volt" power in cars fluctuates widely. The actual voltage will be approximately 12.5 volts when dormant, (less when cold) approximately 14.5 volts when the engine and the alternator/generator are operating, (more when cold) and may briefly drop as low as 5-6 volts during engine start.[7] DC/DC converters will usually compensate for these small fluctuations.[citation needed]

Rarely, more extreme cases of voltage fluctuation can occur when the car battery is disconnected while the engine is running, or when the car receives a jump start. When the battery is disconnected, a load dump transient can produce very high voltages. A car receiving a jump start from a truck will be subject to its 24 V electrical system.[8] A "double battery jump-start" is performed by some tow truck drivers in cold climates.[9]

Design wise one has to take into account intermittent contact, and voltages outside the nominal 12 V DC like top voltage 9-16 V continuously, top voltage at 20 V during 1 hour, 24 V during 1 minute, 40 V during 400 ms.[10] Protection component tolerance example ratings are +50 to -60 V DC[11] Besides this there's also varying temperatures between -40 till +85 °C to contend with that can affect humidity and condensation.[10] Equipment connected this way must tolerate large variations in electrical- and climate environment.

For more, look at table 20-1 in http://www.fordemc.com/docs/download/EMC_CS_2009rev1.pdf which is reference [10] in the Wikipedia article. Granted, that's very conservative, but a 1A 12V low drop out regulator is cheap insurance for a piece of kit like our tablets.
[G Tablet Accessories] wd5gnr:
Interesting. If you plug in tablet and that part number into Google you get lots of familiar looking pictures:

Did you read the same post I did? His suggestion is that 19V is too high and still needs to be converted.
[G Tablet Accessories] sunglint:
I agree, and thanks for the info. I do ham radio and already know to not plug things in until the car is running, actually learned that from xda years back from cell phone charging. I also use Anderson Powerpoles for the connections, very highly recommend these. This does mean that given the same precautions I already follow I can make up a nice charging cable pretty easily. And I'll certainly look in to the low voltage protection, just in case.:)

edit:just saw the call sign, 73s!

My husband just remembered that we bought a power converter years ago to charge a laptop while traveling in Europe.

Would this work without any problems with the Gtab?

Found the model here: http://www.crutchfield.com/S-jg9JaV...er-Pocket-Inverter-175.html?tab=detailed_info
[G Tablet Accessories] wd5gnr:
You mean by plugging in the AC charger to it? Should work fine. The output of the stock charger is about 24W so even if it is grossly inefficient, a 140W power inverter should be fine.

Naturally, I assume no risk, yada yada yada, your mileage may vary, void where prohibited by law.
[G Tablet Accessories] karlkarloff:
Hey, if it helps anyone at all, I bought this car adapter from the radio shack and it works well. None of the included tips worked with my Gtab, so I cut the tip off my included wall charger and using two of the adapt-a-plug connectors also available at the shack, I made it so I can use the tip on either my wall charger or my car charger. Just gotta remember to take it with me, and of course get the polarity right. Its a regulated 12 volt charger, so it reduces some of the spikes and drops from the car battery, the amperage is correct, and the on/off switch means you can wait to turn it on until after the car is started. Reduces the amount of plugging and unplugging nicely.

[G Tablet Accessories] LoganFive:
I have a power inverter that also has a USB outlet on it for the car. I have also seen an auto adapter that had just 2 USB outlets on it at dollar store. Are these tpes safe to charge the gTab?
[G Tablet Accessories] aasoror:
GTab can't be charged via USB
[G Tablet Accessories] greymane98:
Power Brick

So I apologize for what I'm sure is a dumb question but I don't know squat about electricity.

Will this or will this NOT work with a Igo charger. Deals.woot (today only) has a 90W slimline charger that apparently outputs about 19V. The first post would lead me to believe this will not work while a subsequent one indicates it would.

I'm inclined to believe this WILL NOT work but wanted to check.
[G Tablet Accessories] aasoror:
Another member reported earlier that he has researched the power management chip on the GTab and it will apparently run up 18v, this justify why many has been using the iGO Asus netbook tip successfully for so long.

Now for the woot deal, I wouldn't bother with a "refurbished" item when you can get the tried and working travel adapter for $18 (shipped) and $20 (for the version with the auto and airplane adapter) there is a confirmed tip that fits the gtab included.

[G Tablet Accessories] wd5gnr:
The first post says the top end is 18V by the data sheet. Where have you seen someone quote 20V?
[G Tablet Accessories] DanLynch:
I've been using an iGo netbook charger for 3 weeks without any problem. I found it on sale at Office Depot for $8 the week before they dropped the GTab price to $300. Three weeks is probably only 7 or 8 charge cycles, but I've paid attention looking for hot spots, etc. and haven't noticed anything. I don't love the stiffness of the cable, but it was $8. I'm not complaining.

My only charging "problem" is that the silly thing wakes up when it hits 100% (VEGAn-TAB Ginger). Having the screen come on at full brightness just when I'm falling asleep was funny the first time, but it's getting annoying that I keep forgetting to power it off.

[G Tablet Accessories] aasoror:
My mistake, I stand corrected, its 18v.
[G Tablet Accessories] hopbros:
my power adapter plug receiver (male end) on gtablet is bent/broke. is there another option to power?
[G Tablet Accessories] bnovak:
the end in the tablet itself, or the end with the wire that goes to the wall?

if it's the wire end, you can get new plugs at radioshack. But requires some soldering skill to get them on there.

or you can get a universal 12-18V / 1amp charger with multiple tips.
[Desire HD Q&A, Help & Troubleshooting] Locster126:
lately my battery was not at it's best so I decided to do a fresh wipe/install of latest cm7 nightly (38). Now I charged my phone fully to 100% with current widget reporting 0ma and then wiped the battery stats, simple steps I always do with a new rom or fresh install.

Now the weird thing is my battery was at 96% after a phone call and I decided to pull the battery out the phone and plugged it straight back in, when I turned the device back on battery dropped to 84%..???

I wonder why the at has happend? Was the battery not calibrated properly lately therefor causing a bit of an issue for me, it read 96% but 84% was the real value? e.g. was my phone never fully charged lately due to bad battery stats (which I wiped everytime)...

Just wondering if someone can shed light on this situation and or if you had similar experience ?

I'm now charging my battery back to 100% and hope I finally get my good battery life back... :D
[Desire HD Q&A, Help & Troubleshooting] Hawks556:
Why did you pull the battery?

If this happened shortly after you wiped the batterystats it's probably because the phone hasn't had enough time (ie charges and rundowns) to gather enough information to make the new batterystats accurate.
[Desire HD Q&A, Help & Troubleshooting] hedayat7:
normally , phone used up more power to boot. if your have 100% and then you reboot, you will lost 1-2% or at most 5% if you do wipe cache & dalvic cache because the phone need to rebuild the cache.

but if you lost >10+% , it must be that the battery calibration problem. maybe you still have more than 90% after you take out the battery but the display is wrong.
[EVO 4G Themes and Apps] mitchellvii:
One of the sorely (and inexplicably) missing features of Android is the ability to seamlessly integrate Contacts w/ Calendar and vice versa. What I mean is to be able to create a Calendar Event and automatically add People to it, creating a link which may be accessed at a future date.

So far, I am aware of only two Market Apps which provide this functionality, although neither is perfect:

DejaOffice

Contact Event

Is anyone aware of others? I don't mind paid apps if they actually work.

P.S., Windows Mobile 7 does this seamlessly. Have no idea why Google refuses to. I say "refuses" because the integration would be so simple they MUST be leaving it out on purpose for reasons known only to them.
[Nexus S Themes and Apps] shubu000:
Hi all just wondering for those using launcher pro does launcher pro freeze when you first start up your phone

The launcher is fine once you perform a force close so it is not too annoying

Still it would be good if I can change the situation
[Nexus S Themes and Apps] albertogg:
that happened for me too, on CM7 RC2, it had to force close to be responsive again... right now i'm on CM7 RC4 and that never happened again, also try to check if you are on the last version of launcherpro 0.8.4.1... because maybe the lastest updates of launcherpro fixes that weirdness.
[Nexus S Themes and Apps] thenimboo:
I have the same problem with launcher pro (paid version too) on cm7 rc4 so no thats not the solution lol
[Nexus S Themes and Apps] shubu000:
Yeah I'm on the latest nscollab which is just cm7 rc4 and the newest version of launcher pro

Thanks for the suggestion though
[Nexus S Themes and Apps] Fonsinho:
I have the same problem, but I wanted to change the ROM...
[Nexus S Themes and Apps] krohnjw:
I had the same issue with the stock rom. It appears to be LP related.
[Nexus S Themes and Apps] liquelt:
I have the same thing. Launcher pro freezing every time when finalizing boot getting force closes. Paid version too. Thanks
[Nexus S Themes and Apps] phillevy:
This has happened with every single ROM I've ever used - also with my Hero - def LP bug.
[Nexus S Themes and Apps] shubu000:
Good to know that it is a common problem I guess all I CB do is wait for an update
[Nexus S Themes and Apps] ref1ux:
Always had this problem, with my Nexus One, Desire HD and now Nexus S. On booting, LP freezes with a black screen for about 30s or so.

I've just given up with it and switched to Zeam, cos I was getting pretty tired of it.
[Nexus S Themes and Apps] hiro0116:
The defect,occurs when certain apps are installed on SD.

Resolved to move app to the internal memory.
[Nexus S Themes and Apps] josehu:
I have all my apps on internal, but the problem still happens.
[Nexus S Themes and Apps] galvic:
Use Zeam launcher its faster than any other launcher i've used so far
[Nexus S Themes and Apps] schizopunk:
This issue is what made me switch to ADW. It really began to get frustrating.
[Nexus S Themes and Apps] RickROM:
I have this problem also . . . doesn't happen all the time though. Recently it stopped backing up settings to the SD card also :(
[Nexus S Themes and Apps] vitosans:
I have been having this problem as well. After a reboot ( due to cm7 being unstable ) I have a black screen and you would think the phone was crashed if not for BLD buttons working on the bottom and the volume rocker making sounds when pressed, after about 3 mins desktop and bar show up.

Its been getting worse and worse. I have never used any launcher but LPP but I switched to ADW as its getting really bad, I just switched back as I can't stand adw but I think I either have to find a new launch, get used to adw, or something as LPP is killing me everytime I have to reboot.

I am going to cross post this to LPP forums as well as I thought I was alone but obviously if there is a thread on it, then I am not alone. Here is hoping a fix is found as I really like LPP.

Facts: no app's stored on SD, no widgets installed on SD.

Cheers,
[Nexus S Themes and Apps] Greg Tolan:
Switch to go launcher ex
[Nexus S Themes and Apps] hansmrtn:
adw launcher is probably the best all around. i love it
[Nexus S Themes and Apps] shubu000:
Just updated to cm 7 well the newest nscollab the problem is not as bad now

It's wite finicky

I use zeam on my x10 but I like the Widgets from lpp more

Adw... just looks odd to me

Go is not bad but too iPhone like

Regina lags..as you can see I've tried a fair few launchers

Side note lpp would be perfect if it has gestures and screen organisation like if you can rearrange screen order
[Nexus S Themes and Apps] vitosans:
So I figured out my issue, I was using the BFS sched. from netarch and once I switched to CFS things went to acceptable levels, I say acceptable as its still not as good as ADW but its good enough that I can use the launcher I prefer, lets just hope he stays up on the updates ;) still waiting for the rewrite and with his last post of themeing widgets for this version I am afraid we are a bit lower on the queue.

[Nexus S Themes and Apps] Gonizahavy:
installing the app in the internal storage (1gb partition) fixed this issue here.
[Nexus S Themes and Apps] hkt03:
Good to know I'm not the only one with this issue.. LP is on my internal storage too, no sure what causes it to freeze up on boot
[Nexus S Themes and Apps] shubu000:
Yeah that will probably fix it but I like the fast boot up time of having less on the internal partition.

I'm on super aosp and Trinity kernel. There seems to be less launcher pro freeze. Somight be a kernel /Tom issue too. I suspect kernel more.....

[Android Software/Hacking General [Developers Only]] Workman.joshua2:
So this will be a quick question for someone that actual programs. I understand that since I have clockwork mod recovery 3.0 that I cannot use some of the older flashable roms and kennels and stuff because amend script was taken out of it. Or something to that effect. I work around it pretty well. I'm curious as to the difference in the older versions of clockwork mod recovery that used it and the new one that doesn't. Why did they take out amend script besides the obvious reason of screwing everything up? And is there a way to get around it without having to go back to an older version of clockwork? Is there any downside or things I will not be able to do if I go back to an older version? Thanks in advance.

[Galaxy S I9000 Q&A, Help & Troubleshooting] Benjamin Dobell:
Were the contacts, call history and sms databases moved or modified between 2.2 and 2.3.3? Has anyone come up with a way to bring forward their data from 2.2 to 2.3.3?

Backstory

I just finally got around to giving JVK a go. In doing so I attempted to backup and restore my contacts, messages, settings etc. with Titanium. However only a very small amount of the restored data actually seems accessible in apps, memos and that's about it.

To find out what is going on I copied /dbdata/databases/com.android.providers.contacts/contacts2.db to my sdcard and then onto my PC for browsing. I can see all my old contacts fine. So I created a new contact on the phone and then copied the updated contacts database to my PC again. The database has apparently changed somehow but I can't find the new contact at all. It's not in the same table as the others and I can't even find it by searching the whole file for a plain text string matching the new contacts details.
[Galaxy S I9000 Q&A, Help & Troubleshooting] Benjamin Dobell:
Nevermind. I rebooted for a fourth time this morning and all my contacts, messages etc. have been restored. The test contact I created has disappeared though which is odd. However, I'm back to exactly how I was on 2.2 which is great. I guess something weird must have been happening with cached data.
[G Tablet Q&A, Help & Troubleshooting] slsmag:
I have not had any issues with magnets interfering with my display - but I noticed something odd yesterday:

When I first received my Gtab I had good WiFi connectivity throughout my home... but when I put it in a vinyl portfolio case that has several small magnets (for clasps & kickstand), I lots the ability to get a good WiFi connection in the rooms furthest from my wireless router.

Took the GTab out of the case and full strength signal returned.

Any electronics pros/engineers out there know if the magnets in a case would effect the WiFi connectivitiy/strength?

Is this something we should take into consideration when buying and using a case?

[Atrix 4G Q&A, Help & Troubleshooting] Athailias:
Is there a way to create an APN that will force me to run on 2g only? I cant seem to find a toggle for 2g/3g. I downloaded an app by curvefish but it just takes me to the APN list when I click the widget, so that makes me wonder if I can create a 2g APN.

I am trying to convince my cousin to leave apple, but his one holdout is that he has to be able to toggle to 2g. I would like to see how my phone runs in 2g at work, since I work in a large steel building. I've tried *#*#4636#*#* but it just reverts. If an APN cant be set up for GSM I either need a step by step on how to get my APN to not be set to auto, or maybe a script or an apk. ANY info would be greatly appreciated.

Anyone have any idea why this has happened??

I've already had to unroot and return to stock one DHD this week to give back to Orange because i thought it was due to a faulty sim or device. Now thinking it has something to do with rooting and flashing as the problem occurs after doing so.

Any help would be much appreciated, don't really want to be ringing up Orange yet again
[Desire HD Q&A, Help & Troubleshooting] Flussen:

[Touch Pro2, Tilt 2 Themes and Apps] MichaelTV:
Hello all! :)

On my Kaiser, I had a hardware button mapped to launch NoteM, which would auto-start recording. Most useful thing ever :cool:

Upgraded from the Kaiser to a Rhodium (Tilt 2) running the Clean Black Rhodium wm6.1 ROM. Installed NoteM, and used Keyboard Config to map it to the PTT button (tried others). NoteM launches, but doesn't start recording until I manually touch the tiny red recording button on the screen.

There's an option in NoteM, under Advanced Settings, to "Start/stop with a single press". Though active and checked on my Kaiser, it's disabled (greyed out and checked) on my Rhodium :( Has anyone here experienced this and found a remedy?

I've checked NoteM's registry settings, under \\HKCU\Software\Alexander Zavorine\NoteM\, and they're all exactly the same values between my Kaiser and Rhodium. Even copied the exact same files over from the Kaiser, but the "single press" option is still disabled. Do you know what the program is looking at that causes it to cripple itself like this?
