I have an Astro1 charger (2nd gen, rated at 2A), and have found that it will not charge my LG G5 phone (H850). The phone recognises it as a charging device when connected (I get a message in the notification tray saying that a USB charging device is connected), but I don't see the usual lightning bolt on the battery icon, indicating that it is charging. If I leave it connected the charge level of the phone remains constant – it never increases. I am using the charging cable supplied with the Anker charger, along with a Micro-USB to USB-C adapter. The adapter has been tested with my Anker desktop charger and it works fine.
Any idea why the Astro1 won't charge the G5?
Have you tried different usb cable? Also does the charger work on other devices?
I have successfully used non oem chargers/b micro cables on my h831 (should be same on h850 unless updates blocked it).
Right now its charging from a hard wired b micro 2.1a blackberry charger with b micro to c adaptor.
So yea test charger on another device, check cable/adaptor rule them out.

I've just tried 3 different cables. The 2nd one was the one supplied with another Anker charger - that didn't work either. However I then tried a third cable which I got from eBay, and that seems to charge fine. I'm surprised that the eBay cable seems to be more effective than the ones supplied by Anker

I've got around 4 different micro-USB AC Adapters that I have lying around. One is the OEM Lenovo, One is OEM Samsung (i777 charger + Samsung Micro-USB cable), one is a multi-USB port AC adapter with a micro-usb cable, and the last is an iPad 2 wall charger with a micro-USB cable.
ALL of the chargers except the OEM Lenovo ones don't charge my tablet. When It's plugged in, for a couple of seconds it says Charging (AC), and then it just switches to discharging. I've tried all the aforementioned chargers and cables in different combinations, and the ONLY ones to work correctly is the Lenovo combo.
Is there a specific reason to this? Also tried all 4 cables connected to my PC.. They all don't charge efficiently at all.
look at the Voltage and Amperage of the adapter !
Lenovo use 2A if I remember well, the other use only 1A
quyTam is correct... most USB chargers are between 500mA and 850mA. The dual battery design of the tablets requires a min of 2A to charge correctly. This is why most computer USB ports will not charge the device.
However... the changer isn't the only thing restricting the power. The cable you are using can also effect power. Not all cables are created equal.
I stopped by Staples just after getting my tablet and picked up a 4 port 2.1A USB wall charger. It will charge my phone, Bluetooth, and tablet. There are also really nice 2A "extra battery" devices out there that allow you to a charged battery with you that will power and recharge your device.
I also recommend the dock for the tablet... it has a 65w power supply and charges the tablet in a 1/3 the time then the usb chargers.
where to get a charger
i tried 2Amp chargers....didn't help/
my brother says:
"the pins are slightly different/off/longer/shorter/what DID lenovo do here?"
as a safety i bought:
http://www.ebay.com/sch/?_kw=886605022780&_clu=2&_fcid=100&_fvi=1&_localstpos=&_stpos=&gbr=1
just in case...
it costs an arm and a leg for a microUSB charger, but not charging the device for a couple of days would cost me more :S
just another things that makes the TPT slightly less then perfect

Charger
I use a Dell Axim x51 charger and an LG cable from an old phone. Seems to work very well and eBay prices for the charger are less than $4.
http://rootzwiki.com/topic/8523-rev...arger/page__st__40__gopid__448194#entry448194
In my experience a 1A charger will also work. Nothing less than 1A will do anything.
I keep my Lenovo charger in my home office and use a 1A phone charger next to my bed for overnight charging.
I too have a 4 port mains to USB charger: 2A but I thought it was distributed to the 4 ports. If all were being used then each port would only be .5A.
Will have to try it out. If it works it would lighten the travel load of chargers.

That's for sure. I thought the dock was a waste of money until I forked out on Amazon. Saves so much time it isn't funny....

The tablet needs to see 5.3 V, when using >500mA.
Already thinner USB-Cables increase the voltage drop
so the thinkpad wont charge, even with the original charger.
It may have less to do with your charger than with the cables. I bought extra long (6 and 10 ft) USB cables for charging phone and my TPT. The 28AWG of any length won't charge the TPT. The 24AWG 6 ft and 10ft cable *will* on a 2A charger. I haven't tried other combinations. I believe it will charge on a 1A charger as well, but would likely require the larger 24AWG cable.

Design Flaw in Thinkpad Tablet prevents Landscape Mode Charging for Developers
I actually sent my 1838-22U in for service, thinking that there was a hardware problem preventing charging while connected via USB. At first I had noticed that while connected directly to a PC via USB for development purposes (no docking station), the unit indicated that it was charging. However, it seemed to be discharging faster than it was charging and slowly worked its way down to unusable. Lenovo Tech Support indicated that they had heard of this happening, and that I should send it in to have its system board replaced. I sent it in only to find that all they had done was replace the battery and reload the firmware. I did notice, however, that when I connected the USB cable, it appeared to go into charging mode for a couple of seconds then switch into discharge mode. I asked Tech Support about this and they said they this was actually the way it should have been behaving all along, and that this was by design.
The User Manual (see attachment) states only that it might not charge, and that it will only discharge if the tablet "exceeds USB 2.0 power limits" (i.e. 500ma).
Well, the Thinkpad Tablet seems to be pretty good at doing that.
Here's where I present to the development community a conundrum. How can one develop in landscape mode while charging (even slowly)? In portrait mode, one can use the accessory docking station, which uses its own charger and charges through the proprietary connector next to the micro USB port, while separately allowing the USB to be used for data. In landscape mode, there is no such option. I will accept that the unit may draw too much current to charge well via a 500ma USB data connection, but then Lenovo should provide a optional charger that connects directly to the same proprietary connector used by the docking station. This is done elsewhere. For instance, Motorola realizes that the Xoom draws too much current to charge via a USB data connection, so they don't even bother with it - they provide a dedicated charger connection and charger.
==UPDATE== 25-May-2012
SOLUTION FOUND
The solution to using a data connection and charging the Thinkpad Tablet at the same time, without relying on the portrait-mode-only Dock Station, is to connect through a powered USB hub which supports the USB Battery Charging Specification (with a Charging Downstream Port). The specification provides at least 1.5A, which quite handily satisfies the Thinkpad. I found such a hub, the GWCTech HU2V40, on Amazon for $15.99.
If you get this model, note that only one of the 4 ports can be used for high-current charging. It includes a tiny "Smart Charger Adapter" but which appears to block the data connection (at least when when used with the Thinkpad). In other words, ignore the little black passthrough adapter included with it, and plug directly in as you normally would. The instructions don't explain the purpose of the passthrough adapter.
Hi everyone!
I just wanted to ask this: I just bought a 90W charger for my laptop. It is a "Targus Compact Charger for laptop and usb tablet"
It charges my laptop and also has that usb port which charges through a cable, compatible devices. Only that on that usb port, it says that it charges 2.1A, which is a lot. My phone charger does only 550mAh.
So the question, shouldn't I charge my phone through the adapter?
Thanks in advance!
None of my micro USB cables will charge my E970 without a "slow charging" notification except for the cable that came with the phone. Even the venerable 6' monoprice cable isn't up to the task. HTC cords aren't cutting it, either. Does anybody have any 6'+ (ideally a 10') micro B cables that will charge the phone without slow charging? My monoprice 6' cables (i have a bunch) barely keep the phone from losing charge when serving up LTE hotspot, where as the LG cable charges it whilst doing whatever I can to suck down as much current as possible.
Also, I really don't want to short data cables. Somehow the stock LG cable does full current while maintaining data capability, and that's what I'm looking for.

OEM LG cables can be found almost anywhere used so that shouldn't be a problem. Otherwise, you may be looking at the wrong end of the cable. I have a spare tablet plug charger that puts out up to 2 amps and that seems to be what works best for me no matter what the cable. You might want to look for one of those instead of just buying more cables.
FWIW....I had the opposite result. The cable and adapter which has been near my bedside for the last year (for my HTC EVO 4G) kept giving me the slow charging notification on my me LGOG. If I used the LG adapter and cable all was well, but it was shorter than I wanted. I changed out the adapter and kept the older long cable and still got the slow charging notification. It seems most of my existing cables have this issue...even when using the new LG adapter.
I have not looked into power capacities on the usb cables since I charge each night and don't need to recharge during the day. Didn't expect there to be a throughput difference, but the new LG cable does seem to be different.

What is the part number for the oem charger and USB cable?
I use a Samsung charging cable with my LG plug and it charges regularly. I love the Samsung cable because the mirco-usb plug is asymmetric so I always plug it in correctly the first time, every time. Even in the dark. The cable is pretty long too. I don't use the Samsung plug because it only outputs 0.7A though.

I also use a cheapo USB male to female extender that I got off eBay at my gf's place and it charges just fine too.
I'm having the opposite problem, I have had my phone for a month, out of no where the original charger is throwing up slow charging icon. Wierd

Same problem here, just started about a week ago. It doesn't matter what cable I use it keeps switching between slow charge and regular charge.It charges without problems when the phone is off though. Also when I plug my phone into my pc it keeps disconnecting every few minutes. I'm starting to think its a problem with the phone itself and not the charger or cord as they work fine with all my other devices just not the Optimus G

I use all sorts of cables and so far the only time I see "Slow charging" is when it's plugged into my laptop or one of my USB hub. Those are the only times I could narrow mine down to.
In the car I use cheapo monoprice cable and charger, in the bedroom it's using the charger and cable from my HTC inspire. By my PC I have a Belkin 6 plug 2 usb wall charger installed with the stock cable, and at the office an iPhone 1G wall plug. I don't think I have even plugged in the oem charger that came with it.
This information might be out there already, but after noticing the LG charger works much faster at charging my G2 than a Nexus 7 charger, I did a quick test using CurrentWidget to record the charging currents for each setup to see if it's the special LG USB cable or the LG charger base / AC travel adaptor (or a combination of both) which is needed to enable the fast charging.
It's been mentioned here before that there are extra non-standard pins / contactors on the LG USB cable which presumably are used to deliver higher charging current, but it seems that there is nothing special about the LG charger base / AC travel adaptor which use these. Using a standard generic AC charger with a USB port on it is enough to charge the phone quickly as long as the LG cable is used. (and provided its rated for a current output >1.8A)
LG charger + LG cable ......... 1600mA
LG charger + standard cable .... 250mA
2A charger + standard cable .... 270mA
2A charger + LG cable ......... 1600mA
(Tested using D802 running Mahdi Rom 07/29)
well thanks for the info. it is good to know

Neither. I use a multi-USB charge station and a third party USB cable and get high speed charging on my G2.
A number of cables will work but it seems hit and miss. My Nexus 10 is just the same, but even worse. With the 'wrong' cable it can take 3 days to charge, even when off.
I use a Blackberry Playbook charger rated at 1.8A/5VDC, and according to GSAM it charges at up to 1500ma depending on battery level, about the same as the stock charger and seems to charge it just as fast... pretty cheap too, just over $5 shipped... http://www.amazon.com/gp/product/B0052F7ZWY/ref=oh_aui_detailpage_o00_s00?ie=UTF8&psc=1
After i was struglin to charge my G3 through my pc i buy a traveler charger from ebay...its the same as the stock charger and said 1.8mA..i saw that my phone didnt charge as fast as my stock charger and still my wirless chargers couldnt charge my phone...but i saw another strange think...i bought a collored (w/ LED) usb cable to use it as a night light as long as with my stock charger on my bed....my phone charged as slow as i had connected into my pc usb 2.0!
So i test all my usb cables and saw an extremly diverse charging rate..
As you can see in my pics while using ampere all my other (ebay,old phones) usb cables couldn't pass the 350-400mA charging rate..while my stock LG cable could charge a bit more on the Traveler charger while with the stock charger it could get to 1.0A easily..
So whats wrong??Is usb cables equally different as the chargers???
Thanks and sorry about my horrible english!!!

So, as far as I know, with all of the phones I have had, including the G3, charging my phone through a computer always have horrible charge rates compared to charging through a wall outlet. Though, when you say a "travel charger" in not sure if this is what you meant or if you meant some other form of charger.
From your post I've come to view your question as being "can different USB cables charge at different rates?" the answer is yes. Different usb cables will grant different charging rates depending on what battery type that USB cable was meant to charge.
One last thing though, I would love to know what app you use to find all that information!

So just to buy a funcy and funny usb cable with leds inside from ebay is just a waste of money...even with wall charger it can give to the phone max 600mA...
Anyway thanks...the app is Ampere!!!it give you the charge and discharge flow
Hey guys,
At the moment I don't have my USB cable and charger, so I tried it with a few other cables and chargers, but it doesn't charge :/ All have different amperes, 2,4A or 2A or 1,2A or 0,5A (TV and PC). Is there a solution for that?
mine charges with various cables and chargers fine, I normally switch from my samsung cable & charger, choetech cable & charger, xiaomi cable & charger - the cable it comes with is nothing different from a normal micro usb cable, except it has solid copper wires for the power / grounds, but any high quality micro usb cable should work, except it might charge a bit slower.
I have cables from Sony, Motorola, Samsung and zte, none of them works. On my old phones every cable and charger works, but as you said with a different charging speed. Thanks anyways
