Hi all,
Just a quick question, anyone currently using a 2000 / 2100 mah USB car adaptor with their G-Note?
I currently have a 1000 mah adaptor I believe and after a 2.5 / 3 hour journey, whilst charging, connected to the cars bluetooth and using Co-Pilot, I was down to about 20 / 30 % I think at the end of it.
Will the 2000 / 2100 mah USB car adaptors off ebay be ok to use with the G-Note and will it help keep the phone charged when using the phone as a SatNav?
See link to ebay item
Thanks in advance.
A DC power supply shouldn't be measured in mAh... Maybe they meant 2100 milliamperes? 2100 milliamps would be 2.1 amps which is the more amperage than my HP Touchpad charger (2 amps) which should be more than enough.
I don't know how much I would trust an ebay seller that can't even get the terms correctly, but if it's a 2.1 amp charger it should be fine.
Cool, thanks for the heads up PickleHead, I just thought that mAh was the rate of amp flow per hour and didn't realise it was specific for discharge rate of batteries. I'll have another look around.
Just had a look on the back of the USB mains plug for the Note and my Dell Streak and they both have OUTPUT @ 1.0A which is 1 amp right? But a 2.1 amp USB car adaptor should still be fine right? What about 3.1 or even 4.2 amp ones....or are they way too much for the Note?
I've also discovered today what a thirsty little beast the Note is while running satnav. I have a 1 amp car charger with the centre pins shorted together to force the phone to go into "AC Charging" mode, which it does perfectly well. However, over a 20 mile, 30 minute journey I was seeing the battery drop by about 1% per mile (every 90 seconds) whilst charging. That was with CoPilot Live Premium. On the way back I switched to Navfree, with pretty much the same result. I even have CoPilot set to dim the display in between turning announcements. On my old phone that make the difference between a solidly increasing charge and one that struggles to keep up. On the Note it was losing charge even with that feature enabled.
I'm going to need to be finding an alternate charger for the car, so recommendations would be welcome. I can't see a 2 Amp charger being a problem. The Note should take as much as it needs/wants, so long as the charger lets it have the juice it demands.
I would go for the official dock, except I'm told that it won't accommodate the Note whilst protected by a gel skin/case, so the official dock is a non starter for me.

Griffin PowerJolt Micro for iPad.
Output: 5 volts DC at 2.1 amps
Output power: 10 watts
http://store.griffintechnology.com/ipad/original-ipad/powerjolt-micro-ipad
My Griffen Powerjolt charges the battery while Google navigation is running.
It's possible Google nav is less of a power drain than Navfree. I'll have to try it.

I am using the original samsung galaxy tab charger which is rated at 2amps, it works fine with igo, but while using pandora, blurtooth a2dp and igo, the phone charges slowly...
Sent from my GT-N7000 using XDA App
I hav always used a 2A car adaptor as even the Nexus One was a thirst beast as it played the audio over bluetooth to the car dock that had its own speaker.
It works fine with Navigation/Navfree/Waze and the phone charges rather than discharges slowly with the lower power adaptors. The Official Samsung Car Dock comes with a power adaptor that is only rated at 1Amp.
The adaptor I use was intended for an iPad which needs at least 2A. Some adaptors have ratings that should be taken with a pinch of salt. If you can find one rated for an iPad (the type that plugs into the cigar socket and has a USB socket on it rather than an integral iPad connector) then you can't go wrong.
For those asking, I got my Samsung Car Dock from Handtec (in the UK) at: http://www.handtec.co.uk/product.php/5881/samsung-galaxy-note-official-vehicle-dock-kit-
I have the micro usb power cable from the original htc Nexus One car dock. I believe that this provides a 2 amp charging current, and my note charges, albeit slowly while using the phone as a sat nav with google maps
On a similar note about charging (which seems appropriate here), I have the original Galaxy Tab which doesn't allow charging over USB with the standard cable. However I bought an adapter which allows the Tab to charge from a USB port but you can't use it for data, I'm wondering if it's ok to use the same adapter with the Note so it charges quicker off a USB port?
Thanks for the link to the car dock, that looks pretty good

I bought the below car charger because the cheap generic one I had from an old phone couldn't keep up with the drain from the screen when running sat nav.
http://www.ebay.co.uk/itm/290627400358?ssPageName=STRK:MEWNX:IT&_trksid=p3984.m1439.l2649
This also doesn't work, it loses a percent of charge every 10 minutes or so, while I'm aware this isn't alot and I can probably get anywhere in the UK on a full charge, the fact is I want my phone to actually be charging while it's plugged in as I don't always have a full charge and I may need it topping up on my journey in case I don't have another charging opportunity for a while.
I cannot find another genuine samsung product that claims to be compatible with the s2 (indeed the above "genuine" charger doesn't appear on Samsung's website.) There is one on their site (P10CBE In-Car Charger) however it claims to be only compatible with the galaxy tab. While I know it simply has a USB socket for use with any data cable, I'm worried it may damage the phone if rated too high in amps (700mA to 2A is a big jump.)
So I have 3 questions...
1) Is the tab charger safe to use, and does anyone else have this and can confirm it can keep up with the screen permanently on with google navigation running.
2) Can anyone suggest another brand that they have experience with it definitely keeping up with the charge on a galaxy s2, running screen etc.
3) I quite like the look of the official Samsung car mount, can anyone confirm if the charger included with this can keep up etc (also if you know what ampage it's rated to as I can't find this info on the product data.)
Many thanks if you take the time to reply to this, a bit lengthy I know.

Use siyah's kernel to increase the charging current, how high you can go is anyones guess. Stock kernel supply's 450mA when plugged into a usb port and 650mA when plugged into a charger, i set mine to 800mA for both and all seems fine so far.
I have used a motorola car charger and this has actually worked better that the original samsung car charger, charges faster, and has a cool blue light. since the micro-usb is non-proprietary, you have lots of options.
Using an Official charger, better than those cheap ones that fail to keep the battery topped up while using the phone as a satnav.
I have a Sony Ericsson Original AN401 Compact Car Charger and it charges when using satnav.
The main problem with the cheap adapters is the output current, it tends to be too low for GPS. Make sure it is regulated & 750mah or higher.
Hey Everyone,
Surprisingly enough, I have been playing with a lot of car chargers and found a great one. I was talking through Walgreens and saw this one for $5, I turned it around and it charges at 1000mah, that's the same as an AC Adapter charger the phone comes with.
From my experience, most chargers that try and charge the Phone at 1000 mah, such as other car chargers and the iPhone block will either not do anything or charge as USB. This baby actually charges your phone as "AC" and therefore charges much faster than the 500 mah car chargers you often get at other stores.
This was found at WALGREENS, of all places! I recommend it for the AC charge ability versus the USB charge. Another plus is how small it is. It doesn't take up any room at all any barely pops up half an inch.
If anyone has any other ones they commend, feel free to do so.
Cons: It does not have a internal fuse like one of my other chargers, so if there is ever a surge of current, I don't know if the phone has anything built in to protect itself. This is charging at 1000 mah.
Pretty sure this phone will allow for 2.1 amp charging, the SII does, and if you buy any of the following ones, the phone will charge a whole lot faster for a few more dollars:
3.1A Dual USB Car Charger Adapter (White)
Wagan Twin USB/DC Socket Traveler's Adapter
(for the home) PowerGen Dual Port USB 2.1A 10W AC Travel Wall Charger
I've removed text on there for these being made for iPhones / iPads for a reason, but I'll go ahead and state that they'll work just the same for our devices as well....
I bought everything on that list, multiples of the 2nd and 3rd for multiple cars / rooms, so I know they're good quality stuff

But is it recommended by the manufacturer to charge at those speeds? Do they offer any accessories that charge at those speeds naturally?
Because I don't want to charge above anything that Samsung recommends. I know the wall charger is rated at 1amp.
Reason being is that charging batteries faster and higher than recommended can damage or give them false charges.
Just thought I'd comment on this.
I have the 2.1 amp dual port charger from Tech$Go (Walgreens / E-Filliate Inc ) - I attached a picture.
I have a MyCharge power brick, and it all the sudden stopped holding a charge. Now it charges forever, and only supplies power out for a very very small amount of time. I usually charge it, and my phone, using the Tech&Go charger. When using that charger on my other cell phone, when plugging it in/taking plug out I noticed that the battery level was jumping around crazy.
I think it might be putting out too much and I think the higher voltage/amps caused a problem with my power brick.
Anyone have any clues about this I'd greatly appreciate it. I searched on Google and got this link so figured I'd ask even though I don't have this phone, I'm using a LG-Connect from MetroPCS
anyone have experience using car chargers with extended batteries?

Hello guys
I have a cheap USB charger I got on eBay.
I use my phone as a dash board cam (with the screen on) and the battery decharges faster than the charger can charge it.
Will it be possible for me to find a charger that will "keep up"
Thanks a lot in advance!
it could be either the usb cable if it's not stock or damaged but it very well may be the charger, look for a little bit higher end charger (as in not the cheapest one you can find) and it should work
The specs in the item description says 500-700 mA output at 5VDC. Not only is that low output current, but most list a minimum spec, not a range. You can probably assume 500 mA output for that one, which is not enough. The battery will discharge at a higher rate than that charger can provide.
Anyway, look for one that is rated for 1 Amp (or 1000 mA) output at 5 volts. This should be sufficient. I still use my HTC 1A charger that came with my Nexus One car dock for that reason.

Samsung phones seem to have 2 charging profiles, usb gives you around 450mah and ac gives you around 650mah.
650mah still isn't enough when doing nav/bluetooth streaming, until samsung starts using a full amp for charging you will never have a charger that will keep up.
motorola fast charger
you can use this one:
Search for "Motorola Vehicle Power Adapter micro-USB Rapid Rate Charger" on Amazon
I have been using this for quite a while now on Nexus 7, its just awesome. It has an output of 950+mah which would be enough for Nexus 7.

I used this Griffin-Powerjolt. Found it at walmart, and took it apart and soldered the two middle pins. But found my info here on XDA, but cant seam to find the thread. And I can play games, stream music, etc, and my charger keeps up and charges fine. But this post sums up your question.
Also I'm on AOKP JB and when I was on there ICS roms they have the charging mod so even when I had a cheap-o 500mah charger it saw it as an AC charger and charged at AC charge speed. I think also Cyanogenmod has implemented this also, but im not sure.
+1 for the Motorola charger recommended earlier. It puts out 950ma so the phone will read charging via 'AC' rather than 'USB'. Charges quick and will be able to keep up with BT and GPS navigation. Here is a direct link:
http://www.amazon.com/Motorola-Vehi...Charger/dp/tech-data/B000S5Q9CA/ref=de_a_smtd
I've been using it with all of my Android devices and works very well. Great quality as well. Highly recommend!
I use the 2A Amazon branded charger. You'll want to set it in fast charge, because the phone thinks it is a usb charger. You can open it and short the pins, if you want.

Actual current draw (aka...how fast your phone charges) is not determined by the charger but rather by the phone itself. The ratings on the chargers is what they are capable of, but will be dependent on the device. People would be frying devices all the time by using one device with anothers charging cable that has a totally different output if it was determined by the charger alone.

x3 on this charger. Have used it for the last couple of Android phones as well. Work fantastically with my Nexus streaming music via bluetooth to my car stereo. Never has a problem keeping up.
I'm using my N1 charger still too. Keeps up with nav, stream music, and max brightness. I don't use BT, but otherwise I always gain quite a bit of charge.

oh in another way, you could install a custom kernel and enable fast charging, works for me though.
I bought 2 of these charging only cables. They work perfect, full "AC" charge through any car charger port.
http://www.amazon.com/gp/product/B007F1DV76/ref=oh_details_o02_s00_i00
Put one in my car and my GFs car.
The problem is a "USB" charger spec doesn't allow for the higher voltage charging under most situations. Any cable that does provide the full "AC" charge is a 'non-USB compliant' charger (or something like that), thus, the cable I listed above doesn't say "USB" charger. That is a very brief explanation.

That works fine but I heard it uses your battery faster.
Until now, I be been using whatever cheap 1A car chargers I found on eBay. They show up as AC on the phone, and charge acceptably fast, definitely better than USB, but worse than the original AC charger.
With GPS usage (sygic, 3d acceleration, full backlight, GPS, speaker, and mild CPU usage) the battery actually drains while charging. Starting a 4 hour trip with 100% charge resulted in 40% of battery, even if it was charging on the whole duration of the trip.
So, this summer I'm going to do some bigger road trips. I need a car charger that gives enough power to charge while doing the GPS usage described above. I suppose I'm going to need a charger that gives close to actual 2A, not only in theory. Any suggestions?

that is due to the fact that your phone only requests 500mA from the car charger (while your phone uses more)
are you using a custom kernel?
I use ElementalX, which has the option to enable fastcharge, which boosts it to 900mA (enough to charge with everything on)

Is there any downside to enabling fast charge. No sure if there isn't why every kernel doesn't enable it by default.

Because in theory USB ports of e.g. laptops only give 500mA. I've used it on a lot of car chargers, USB hubs, desktops and laptops and never had any problem.
Even if something were to break, it will be your car charger, because your phone can handle a lot more than 900mA, and if your car charger is rated for 1A that will suffice.
Actually the N5 stock has Fast charging enabled. The problems usually are most commonly from poor USB cables and sometimes bad chargers that don't output what they say. If you are dropping battery charge that quickly from a 1A charger most likely you have a problem with one of the 2 I mentioned above. DL CurrentWidget from the play store. Set the Update Interval to 1 sec and then plug in the charger. IF it is a 1A charger you should get just under 1A maybe about 900mA or so. Since you are losing battery life while charging and using the above things you mentioned I would imagine that it is getting about 500mA or less.
Try the test with your OEM cable from the N5 since it is more likely to be better at handling the higher current charge rate. That way you can figure if it is the cable or the charger itself.
Here are ones that MmmmmBacon suggested in his Cheap Charger thread. I am probably going to grab one myself.

Highly recommend this. It can charge two N5s at full speed with no issue.
Sorry for the late reply... I didnt have time to even read the replies till now.
I never believed that a cable could make that much of a difference, but testing right now with the original LG AC charger and misc USB cables the difference is immence. Best performance I managed to get was from the included cable of my Anker powerbank. its around 980-1010mAh constantly, vs the 400-600 most cables do.
I will test in the car ASAP.

That is one of the best car chargers I've found, I use to charge my Nexus 5 when I'm on the go.
This Anker charger solved it.
It gives a steady 1000mA that is enough to charge and use GPS.
I have to give a huge thumbs up to Anker, because together with the car charger i also bought the Astroslim 3 6000mAh powerbank, which charges two devices the same time, at a steady 1500mA each!!! I loved bothe the car charger and the powerbank, definitely worth their money.
