Wall charger ...

Hi,
Can you use the wall charger from the Galaxy Tab 7" ?
Please if you have both devices to try it.
I would like to import this new 10.1" to Europe, The Netherlands.
And I am wondering the wall charger requirements.
Thanks.

I would also be interested to know if the charging cable is compatible between the original Galaxy Tab and the Galaxy Tab 10.1.

Yes it works. I'm using my cable that came with my 10.1 to keep plugged into my PC and I'm currently charging my 10.1 on the cable that came with my 7. It went from 0 to 50% so far no problems. Not sure if it charges any faster/slower than the one that came with it but I'd assume they are the same.

Thanks, so I can order NL gt 7 charger for my US gt 10.1 for use here in NL.

Thanks for that. Picked up a couple of genuine Samsung chargers from Tesco in the UK for £4.97 each (reduced from something like £40!). Potential UK buyers might want to grab a spare while they can!

i think he was saying that the cable will work. The charger might not. I was trying to use my cable with other USB wall chargers but the device won't charge on them... my guess is because they are less than 2ah. I would make sure the specs on the tab 7 charger match up to the 10.1 charger to be safe

The Galaxy Tab charger I picked up today is rated at 2A so it should be OK, with any luck!

cable and charger both work. both chargers are 5v 2A. one reason why it charges slower than the xoom and tf.
on the upside it does trickle charge via standard usb. my tf won't and of course my ex xoom wouldn't.

Sweet, i'm gonna have to pick one of these up then

Wow, those chargers are expensive on amazon. Does anyone know where to get cheap ones?

Ebay is probably the best place for all things cheap, unless you're wanting a samsung branded charger

Haven't checked for the exact right one but dealextreme.com has been the best in the past for misc electronics cheap.

good to know that. like many android gadgets, once you have it, next natural thing is to put several chargers in several places.

So, we all know what to look for specific.

I hate how you can't just plug it into any usb. I have usb adapters everywhere and it would be nice if I could charge it while plugged into my computer

I posted this in another thread, but with these adapters, you can charge off ANY USB port;

I've bought two, leave one at home and the other comes travelling with me.
I also use a few third party cables designed for the original Galaxy Tab and they work fine. So happy to be able to charge my 10.1v anywhere

it does, but it seems like 1% per 3 min. just plug it in and see. it's the only honeycomb tablet that i've had that actually does charge via usb (xoom, tf, and gt101). the tf doesn't, but i'm sure it would if i had usb 3.0.

I really want a wall charger I can throw in my flight bag. Anyone have one they've found on eBay that charges the Tab 10.1? I really don't want to drop $40 for the OEM, ouch!

Seriously, why not buy one of the adapters that I posted about and use any charger you want? I think I paid about $7 Australian for two and now I can keep using all of the USB wall and car chargers I have amassed over the years owning Win Mobile and Android phones
If your heart is really set on buying a proper wall charger, if it says it will charge a Galaxy Tab (original) or iPad, it should charge the 10.1

Where to buy original charger?

I need a new charger and i would like it to be original, do you know where to find it?

Nope. And ive looked. Too many fakes anyway and low quality chargers. I use my moto, n1 and an atnt charger for my a/c chargers. And a dual port sony a/c usb charger.
...

I bought one from Amazon just last week. It matches 100%.
The picture on the amazon link shows the micro end of the usb to be off center. The cable I received is identical to the one from Samsung, down to the texture of the cable.
http://www.amazon.com/gp/product/B006YCORR0/ref=oh_details_o05_s00_i00

I bought the Galaxy S2 charger, its a normal charger without the socket + usb lead, so it allows me to keep the usb plugged into my PC while i can have the AC charger somewhere else. you can pretty much pick them up anywhere, i got a genuine one from eBay:

Here is an OEM one straight from Samsung but I doubt you will want to pay the price.

You can try to get a Sony EP850 charger.
The output is 1.5A which charges very fast. I'm satisfied with it!

I just bought this one but haven't received it yet. It looks identical, though apparently it's for the Galaxy Note. Same voltage/amperage though, so I bet its exactly the same thing.

Thanks for the answers

Any microUSB charger with output of 5V/1A will work, but you can find some charger with 5V/2.1A which will also work tablets and support future products.

Actually, I've tried one of my micro USB charger with 2A output.
GN just wont charge on this charger.
But GN charges well with my Nokia 1.2A and Sony 1.5A charger.

I have a charger with 4 usb connector at 5V/2A and it work ok.

A better charger?

So after having owned the Toshiba Thrive and now am using the Samsung Note 10.1, I have to say I'm disappointed at how slowly the Note 10.1 charges... Even after leaving the Note plugged in to the stock Samsung 5V 2A charger while using it, I can discharge it faster than it can charge (mostly playing games), which is sourly disappointing.
I saw a singular 5V 3A charger on Ebay, but it was for a car... not to mention no telling if it was legit.
So does anyone have any suggestions on a better charger?

There isn't one- there's two charging modes- "high-power" and "USB", and the rates are set by the hardware (with help from the kernel software) so getting a 3A supply won't charge it any faster.

I believe the Toshiba Thrive has a 10.8 volt 2030 mah battery and the charger puts out 19 volts........ so it should charge a lot faster.
The 5v 3a chargers generally are a 2 port charger and one port usually puts out 2a and the second only 1a.

QI Charger which PSU ?

Hi
Didn't think of this before I bought it.. But I've just received a QI charger from Amazon.
Which charger do I used with it?
The one from my nexus 5 or the one from the nexus 7 2013?
Ideally I want to be able to charge either device.
The QI states 5v 1500ma input.
Also what's the best app to monitor the charging, time, input heat etc?
Thanks

I can't say for what apps to monitor times etc... But
Did your qi charger not come with a mains power adapter.
I can't say for the nexus 7 but the nexus 5 comes with a 5v 1200ma charger so it won't be able to supply the current that your qi pad needs.
Have a look on your nexus 7 power brick. It will tell you what it outputs.
Nexus 5
Input : 100-240V

Output : 5.0V 1.2A

what brand? you can try plugging it in your laptop. mine (Nillkin) says Input: 5V/2A but it still works just fine if i plug it in the laptop.
otherwise I use the Nexus 5 charger. I think it's just the maximum your charger can handle.

You can use any USB power source... What varies is charge rate. I picked up a 2amp supply from amazon. You have to figure in less than 70% efficiency... Especially taking into account non laboratory ideal conditions and manufacturing...
1 amp input will be like slow charging from a computer at best. 2 amp will be on par with regular wall charging if not better. You always want an adapter that is above what the charger can handle to make full use of the charger... Lower ones will still let it work to lesser and lesser degrees till it doesn't charge the device depending on supply and device needs

It can be used with either the Nexus 5 or Nexus 7 AC Adapters. The Nexus 5 is 1.2A and the Nexus 7 (2013) is 1.35A I believe. Neither will fully power the Qi charger, but it will still be enough to make it work. The charging time for your phone will just be longer since the Qi charger is not being provided full power, so the current the Qi charger can provide to the phone will also be lower. If you want your Qi charger to operate at full efficiency/power, try to use an AC adapter that is 1.5A or higher.
Since your Qi charger only requires 1.5A, the Nexus 7 AC adapter is the closest, so I would recommend using that one.
In the future though, you might want to consider buying a higher output AC adapter:
The Blackberry Folding Blade Charger is 1.8A output, and microUSB, so you can plug it directly into your Qi charger (or phone if you ever need to charge you phone at rocket speed!):

The Boxwave Fast microUSB charger provides 2A output, microUSB as well, so if you ever buy another Qi charger it would be good, as many Qi chargers require 2A input.

You could also just buy an adapter similar to the Nexus 5/7 without the cord attached. For example, something like this.

I've tried my nexus 7 charger with the qi pad and ran battery monitor widget.
Tablet showed at -432ma, sat it on the qi pad and it changed to -124ma!!
Why a negative figure ? I assume I'm using more power than its charging.
Would a 5v 2a charger male much difference ?

Hi
Just had a thought the value I'm ready is when the screen is on, out it being off make any difference ?

Try using currentwidget (free) to read just the current being provided during charge.
Set it to update at 1 second intervals.
Even with the screen on, if you are not using navigation, streaming stuff, gaming, etc. it should charge even if it is not getting the full 1.5A current provided to it. It would just charge slower not discharge.

As I learned from another thread, the cable makes a significant difference. After using a 2a charger, current widget, and checking the charge of all my cables: 2 provided about 1.4a, a few 1.1a,and a large number of cables cut power down to 600 down to 300.
You need a capable 2a charger, a quality cable that you have actually tested, and a qi charger that accepts 2a and doesn't lose a majority when converting to induction.

You might have read that from one of my posts hahah.
I've said in different Qi charger threads to have a good 2A charger and to replace the included micro USB cable with higher quality cables (premium monoprice cables, or the Motorola Ecomoto)
I did a video demonstration on USB cable quality here. Didn't expect that drastic of a difference.

Hi.
I'm using a nexus 7 charger
1st models charger is 5v 2a
I've tried the following cables: included, nexus 5, nexus 7 (1st edition and 2013) and a couple of other cables.. All with very similar results.
Think I'll send this charger back and then with a recommended one.

[Q] Need Opinion/info on Qmadix 4.4A USB Triple Travel Charging Hub...

So Im in desperate need of at least one more Wall charge for my galaxy note 8.0 and Galaxy S4. The only problem is they're either pretty expensive for the more legit products, or sketchy. I just need the white box part that goes into the wall outlet. SO incredibly embarrassing and frustrating that I can't seem to figure out what it's actually called. In any case, through my searches I found this:
Qmadix 4.4A USB Triple Travel Charging Hub
It allows for three ports, but each port is designated differently. well, okay... two are the same (1A), but ones different (2.4A). I have no clue about electricity, except to know if you don't use the samsung recommended converters it could damage the battery in the long run. Im under the impression that both of my devices require 2.0A. Does this mean only the 2.4A port would work?
Is anyone familiar with this Item Ive listed? Could I use this device to power bot my Galaxy Note 8.0 AND Galaxy S4 at the same time?
It seems like such a great deal and very compact. Can't pass up without at least asking about it.
again, Im asking about the:
Qmadix 4.4A USB Triple Travel Charging Hub

I appreciate the reply. I had actually seen that and immediately fell in love... but I just as quickly wrote it off because of the additional cable thats required to plug it into an outlet. I need something more compact... something with collapsible prongs.
Another one I was looking at is this one iXCC Dual USB 4.2 Amp (20 Watt) SMART High Capacity AC Travel Wall Charger...
Any thought?

Ports listed as 1A might still be able to supply 2A for your phone, but they might be right at the top of their current limiting (thus running warmer). The whole thing about using only Samsung provided charger is just to scare you off so you buy their original overpriced accessories But there is a truth to it as well, when you buy cheap stuff from ebay where they sell 1A rated outputs labeled with 2A and can run into a problem above (overheating, which causes short, which can cause a damage to your phone). Anker is a trusted brand with a decent quality control, RAVPower is good, and I heard of QMadix before as well.
Here is a problem. When you are dealing with wall outlet converters with multiple outputs that carry a lot of heat/power, you are too close to the main electrical outlet. So, I would be careful not too overload these. Maybe using 2 devices plugged in at a time is ok, but NEVER 3 at a time. When you have something like that 40W Anker converter, you are placing it away from the outlet, it exposed to air circulation from every side (cooling it better), and it should have some fuse or internal protection in case of a short. I understand, for convenience you need wall converter that plugs in, but make sure you get a double one, not the triple output one because i would consider those to be not as reliable when you are charging 3 devices at the same time while plugged into a single wall outlet directly.

Anker also make this one: www.amazon.com/Anker®-4-Port-Charger-Travel-Adapter/dp/B00EI8SS4U/ - but I would not load more than 2 ports at a time. Or if you load 3 or 4 ports, make sure it's not overnight when you are sleeping and that all 4 charging devices are not drawing max current

Btw, one quick question... The Anker 40W 5-port USB wall charger... Should I only charge 2 devices at a time with it aswell? or was that referring only to chargers that plug directly into the wall because of the heat issue?

You can use all 5 ports on that one (40W version that doesn't plug into wall outlet directly). That how I do it all the way, mostly using 4 ports at once to charge my Note 2, my Metawatch smartwatch, my mp3/DAP player, and external battery. Sometime also add my wireless headset too
