That allows the micro usb to put out more voltage to support more usb storage devices that require more than the 100v of power that it puts out by default?

It's impossible, it's an electronical limit, the device can't do it physicaly, that's all, sorry ^^
So will a powered usb hub work for that type of thing?

Yes, it will.
Great. But does the powered hub have to be the type that needs an a/c adapter or can it be a self powered hub? Sorry to be a nuisance with the questions.
Sent from my ADR6400L using Tapatalk
a bus powered hub wouldn't make any sense, would it? how should it get more power than the device can deliver by it's physical limits?
so answer is clear: No, only powered (yes, the ones with own batteries or A/C adapter) hubs will do the job.
I think he was talking about battery powered hub, and i think it could work ^^
Hehe, I can't believe nobody made a joke about saying 100v instead of 100mA.
Anyways, you could also splice 5v into your usb cable, either from a wall wart or from batteries, but if using batteries, I'd use a lithium ion pack and a boost converter, something like a Texas Instruments TPS55065QPWPRQ1.

Lol, no problem. I mix things up all the time. I was just surprised someone hadn't jumped on you for it. But for the record, mA, not mAh. mAh is milliamp-hours, which refers to a batteries capacity, not the amount of current being consumed.
Okay, gotta get the OCD in check and stop correcting people now.
Seriously though, it wouldn't be hard to splice some power into a usb cable. Just slice through the outer sheath, melt a section of the sheathing off the red and black wires, and solder on a 5v wall adapter. Maybe a diode to shunt current only to the drive and not the archos, probably not necessary though.
To use batteries, you'll probably need to regulate the voltage. Most usb MCUs only accept about 4.5v to 6v, so 4 AA batteries(1.5Ah/6v) being drawn at ~400mA would probably sag under 4.5v pretty quickly. Thus, you'd need lithium ion, but you can only get them at 3.7 or 7.2 volts, meaning it would need to be voltage (and amperage) regulated.
Maybe there's enough demand for me to build a prototype and have it produced? It would probably run $40-60 USD if mass produced, but you could build one at home for $20 if you have a spare usb cable.

I just ordered one of these:
tinyurl.com/3mzzzz5
in hopes to deal with the above problem. It claims to have a built-in battery (in other ads for this product), but unsure of it's capacity (700 mA perhaps). Reading between the lines on other poorly translated ads it claims to be able to power a hard drive (a 2.5" laptop drive I'm assuming). It also comes with a boat-load of adapters to all kinds of small devices, so I figure it might be useful elsewhere if it doesn't work out for this.
Anyway when I get it, I'll report back on how well it works.
Thanks. It looks promising. And if our works I'm definitely gonna get one.

That's the general idea, but the hub may need drivers that android doesn't have, and don't expect much from the solar cell. I'm guessing less than 100mA in bright sun, but it'll be interesting to see. A 2.5 inch drive should be able to power off the host USB, but if you connect two through that hub, I doubt you'll be able to get a good spin up.
Iflip: This is basically what you want to build: http://www.ladyada.net/make/mintyboost/
You would just need to add another usb port connected directly to the pins of the port he's using to charge from. The "minty charger" would supply the extra mA, and the data pins would connect straight through the two usb ports into the Archos, so you wouldn't have to worry about drivers or anything.
Basically, if you can find any USB charger, and add another port to it, so both the archos and the hard drive can be plugged into the same charger, you'd be golden.(As long as you connect the data pins on both together) You could even add a port to an old Ipod wall charger, anything that provides power to usb devices. You just have to add another port to it, matching the 4 pins, which is easy. +5v to +5v, ground to ground, data + to data +, and data - to data -. I think you get the picture.

Yes there is.
A very bad a simple hack can provide more than 100mA to the USB port.
I had 1 usb key working and others not working due to this limitation. This got me really upset!
I've search the kernel sources, hacked quickly the kernel, build a new one, flashed it on my A70S running UrukDroid 1.0, and voila! My key is now working (with a 200mA limit on the port instead of 100mA)
Here is the kernel/initramfs for UrukDroid 1.0 build with $auron kernel sources (1.1b3 kernel).
It has Cgroups with cpuacct based on UID grouping (like HTC does on the Desire), but the rest is pretty much standard and is build with $auron's settings.
Flash it with SDE.
Don't blame me tho if you toast your USB port! It's working for me with a USB key, it may not with a USB hdd. I've set the limit to 200mA and not 500.

Are you 100% sure? I'm getting apparently more than 100mA out of my USB to power my greedy USB flash disk
Cheap battery powered USB hub worked with my A70S
So I bought a DTech DT-4012 from tmart.com and it [mostly] worked with my A70s!
It is a cheap solar & battery powered USB hub.
It powered a USB mouse and keyboard just fine. This is real handy especially when you are trying to use the A70 with an external display through the HDMI an HDMI cable. I get a normal mouse pointer and a functional keyboard.
It even powered a 2.5" laptop hard drive, but only for about a minute or two, enough time for at least my A70S so mount the file system, but not much more.
Of course it powered less power hungry things like USB "thumb" drives and card readers fine too, this included ones that the A70 could not power by itself.
The thing contains a [small] 700mA Li-ion battery and a voltage converter that produces a steady 5V out the USB ports for as long as it can. It is possible that the short run time for the hard drive could be an overheating problem with the voltage converter that might be solvable with an addition of a small heat sink. It is also possible that I don't have a full charge on the battery yet (although it claimed it did as the "charging light" went out), but this was the units first time use so the battery might just need some cycling. I'll investigate all these ideas further.
The unit does NOT have a connector for external power but I'm thinking of adding one so I can plug in AC adatpers and/or larger battery packs. This is assuming this is what is needed to get reasonable life running a 2.5" hard drive.
Oh and on the solar cell: I don't expect much power from the approx 2" diameter cell, it would probaby charge a small mobile phone about 1/2 way if you left it out in the sun all day. It is probably more useful as a trickle-float charger for the internal battery as in average ambient light might keep the battery topped off as it is being stored.
Finally the thing comes with all kinds of USB adapter cables for mostly older mobile phones. Could be useful to some.
why? why did motorola use a proprietary charging cable? it would of been so nice to have a micro usb cable to charge the xoom. im very worried one day that needle proprietary cable going to break and it wont charge my xoom anymore.

Simple, many recent tablets use proprietary cables to allow higher current and faster charge times.
The average usb cable hooked up to your pc provides about 500mA
The proprietary cable for a modern tablet like the XOOM can deliver around
1.5A
With a micro USB cable it would take forever to charge the XOOM. Then people would be complaining about why the XOOM takes so incredibly long to charge, and bashing motorola for the problem. Instead Motorola chose to do it the intelligent way, by separating the charge function to a proprietary cable to allow very fast charging, and including the usb cable for data transfer.
When I see a proprietary cable I don't think - crap why do they do it this way. Instead I think wow great, that means this thing was designed for fast charges.

THANK YOU lol finally someone that understands.....
plus, the input voltage in to the tab is 12v, hard to get 12v from a 5v USB supply...
For a bit more info, I too wondered about USB charging. The limit seems to be when the Xoom is running, the current drain can be upwards of 400 mA so I could see a situation where a USB charger at 500 mA would overload if you did too much on the Xoom during charging. That would be good enough reason to avoid that design mess. "Do not use during charging" would not be sufficent protection. The Moto Mains Charger manages 1500 mA for a couple of hours which is wonderful. Now if only I could charge my Nexus S that quickly

I am really glad that trickle charging is not possible with the Xoom, saves a lot of problems...I just wish they had used a different connector for the power. Something a bit more durable and commonly included in third party multichargers would have been nice...but one can't have everything.
I still support the seperate power cable choice for all kinds of reasons.

Just amazes me that folks will complain about anything and everything. Good grief, it charges in no time and runs more than a day when it does. What more can you expect?
I like the idea of a separate charger, but the only thing I take issue with is the design of the charger it self. Luckily, I just set mine on the dock before bed. The dock doesn't use that flimsy pin, it uses the two gold plates at the bottom to charge.

i love the proprietary cable. It is SOOO much faster. My Galaxy tab with a 4000 mAH battery took almost 4 hours to charge and i was lucky to get two days usage out of it (standby time and normal usage combined). My Xoom (no idea on mAH size) charges in 2 hours and i get 90 hours usage out of it (mainly standby but still a lot of screen on time, wiht a much larger and brighter screen to power). LOVE it.
Yeah I wouldn't worry about the Cable its seems durable, only thing I AM worried about was how you plug the wires all on the side of the device, I feel like there's abit of give on the wires when holding it sideways, I wish it was more like the iPad.
You know the first time I saw that the tablets used a seperate charging cable I was like, "why?" but then I stopped and think, there's no why a USB (let alone a micro-USB) can charge those suckers, so I'm personally glade that tablet makers did what they did and make it seperate.
I just wish they chose a 30-pin connector instead of this tiny one. The slightest mistake while it's charging (like say you trip over the cord), and there goes your xoom for repair/replacement.
Lets not rule out USB charging. Yes, I love going from 5% to 100% in about an hour. But I also have USB plugged in for hours on end when doing my thang. . That being said, we do not know for certain that USB charge is a hardware limitation. Yes, USB puts out 500mV. But I can tell the kernel to suck in whatever. If the hardware is capable, its doable.
I still think the option should have been given to us. Cuz many if not all of us have micro USB around. I for one only take a single micro USB in my pocket for my phone. So its would have Been nice to be able to charge both device with one charger. But I mean scull charge usually carry me all day. So I don't see it as a major problem right now.

Its actually 500mA not 500mV. Usb provides 5 volts at 500ma for usb 2.0 and that will be picked up to 900ma in usb 3.0. Even with this in mind it isn't the biggest problem with stoppinh usb charging in the xoom. The issue I believe is in the fact that the current charger is 12 volts and 1.5 amps. That's more than twice the volts at tripl the amperes.
Even beyond the amperage issue charging a battery that is set up to input from a 12 volt source with a 5 volts supply, even if it was possible with existing xoom hardware it would take forever!
I wish there was a way to have both options available for charging. Use the USB if you have no access to a AC adapter, albeit, a slower charge.
It seems that there's a false dichotomy here; the options aren't only trickle charge by usb and wall adapter with the proprietary connection. What about a wall charge via the usb port? I don't see why the usb port couldn't be used for the charge. I can trickle charge my n1 or I can plug it into an outlet, which charges the phone much faster. I'm sure the xoom could have been designed to suck in more power when conected to an outlet.
The only plus with the proprietary port is that we can charge and have the xoom connected to a computer or peripheral at the same time.
I have to say that the Snapdragon 800 Quick Charge 2.0 feature is working pretty darn well. I measured 60% charge in 1 hour (just got the device yesterday so it's a fresh configuration)
Love that feature. Definitely makes worrying about battery life a little less stressful.

I used the standard charger. Btw the 60% charge in one hour is just based on one observation. It was my first charge. I started charging the device from 1%. An hour later it had already 60%
Don't know yet if it will slow down when it reaches the full 100%.
Anyway, it's just a first observation. Need some more observations to determine the average charging time. (Wonder if there's an app for that)

It's susposed to be USB 3 I think and have an output of 1.5-2A in order to quick charge... though any info is severely
lacking.
You need the charger that is supplied with the phone to be able to use the QuickCharge 2.0 feature. I don't know if QuickCharge is also restricted to the USB cable that is supplied with the charger.
Other generic chargers (like chargers you got with your phone 2 years ago) will charge your phone but not with QuickCharge. So it will take longer, just like any other phone without the feature.
Please correct me if I'm wrong, but I thought it was required to use the specific QuickCharge charger to use this feature, and yeah, it does charge a whole lot quicker this way!
EDIT: These new chargers are backwards compatible so you can also charge phones without the QuickCharge chipset with the special QuickCharge charger but they will charge normally and will take a long time to reach 100%, just like the ol' days.
i use the charger of xperia z because the written specifics are the same of z1 charger. wrong?
Cable is funky. Tried two other cables because the standard one is so dang short and both resulted in charging slow as a snail...
Oops, maybe I was wrong and doesn't the current charger support Quick Charge 2.0. My Z1 came with the Sony EP800 charger. It seems that they already used this charger even before Quick Charge 1.0 was released.
Anyway it seems that Quick Charge 2.0 adapters may come soon. The components are already on the market http://www.dataweek.co.za/46872n
Quote: "Tests confirm that smartphones with high-capacity batteries can be fully charged in as little as one hour using Quick Charge 2.0"
Oh yeah!
Anyway, my Z1 still charges pretty fast. But no problem when I can get a full 100% charge in an hour...!. Would be even better when they put this technology in a portable charger. Maybe the newly released http://www.sonymobile.com/global-en/products/accessories/portable-power-supply-cp-f1lam/ ?
Mine charges seriously slowly with the bundled charger/cable, not sure if I've just got a duff one. Charging it throught usb plugged into the computer charges it at a normal speed. Planning on picking up the dock when it finally gets released, hopefully thatll give a good speed.

I used a usb extender and the charging speed went terribly low.. I think it is due to loses in the cable...
I'm having trouble charging over usb, is it because usb doesn't provide enough current or do I have a faulty handset?
Edit: When I say charging over usb, I mean from a usb port on a laptop.
I remember when tablets with large batteries couldn't be charged from some chargers, or via a USB port, so I wonder it this is the problem?
Also, do we know for a fact that the Z1 supports Quick Charge 2.0? I thought this had been delayed, and probably just supported the older version - as seen introduced on the Xperia S.
After careful thought, I decided to return my shield tablet (so I won't be doing any dev work for it.) The tablet just isn't right for me.

I just felt obligated to let people know that I've changed my mind and so won't be doing dev work for the device.

1. Anger at NVidia for what I feel was purposely misleading consumers about the lollipop release on the 18th (US/LTE). I know they turned a blind eye to the leaked update, but they should have disclosed the potential delay when they made the announcement.
2. While the battery life was acceptable, the charging wasn't (for me.). Even with a high amperage charger, the silly tablet would lose charge even playing simple games like "dots" or "threes."
3. I wasn't satisfied with nvidias resolution (or lack of) for the cracked edges issue. Too many customers were (and still are) experiencing the problem even after nvidia claimed it was fixed.
4. My wife asked me to stop spending money on geek toys, and I really wanted a nexus 6

Were you using the stock cable and stock charger? Some cables do not support high charge rates and even some high amperage chargers are wired for apple devices and most android devices cannot charge higher that .5amps with them.

The stock charger was worse than a computer USB port. I only use higher end USB cables, and I have various charging bricks from several different phones and other devices. The simple fact is that the charging circuit just wouldn't pull enough amperage. (None from apple, BTW). I even have 3.6 amp USB charging ports hardwired into my electrical outlets in various rooms of my house.

That is not right, and sounds like the power brick had a problem. Pc usb should only be providing .5 amps way less than the brick. My brick charges vastly faster than a pc usb port.
> I only use higher end USB cables
High end is only part of it, you need ones that are specifically built with thicker gauge cable.
>None from apple, BTW
It does not have to be from apple as most usb charger manufactures still follow apples charging standard. They do not do the standard for dedicated charging devices (short data pins) that most android device follow. Actually, every dedicated charger i have bought i have had to solder the data pins together for full charging.
Okay. You are assuming that I don't know my way around USB charging. The opposite is true. As well, it really makes no difference in terms of the nvidia tablet. It's gone.

I usually stick with the OEM charger and cable with devices but since the Shield K1 doesn't ship with either I was using another cable I had around.
I noticed the tablet was discharging while in use even on a 2A charger. I tested the charger's power consumption with a wattmeter and found it was only running about 1A. The cable was inadequate. Trying different cables was an illuminating experience.
I found some informative sites about this. Here are my favorites.

I usually stick with the OEM charger and cable with devices but since the Shield K1 doesn't ship with either I was using another cable I had around.
I noticed the tablet was discharging while in use even on a 2A charger. I tested the charger's power consumption with a wattmeter and found it was only running about 1A. The cable was inadequate. Trying different cables was an illuminating experience.
I found some informative sites about this. Here are my favorites.

Ive seen some other people asking about charging problems in console mode so I figured this might be useful info.

Those are some really informative links. Thanks for that.
Noticed that too! Bought some days ago an longer USB cable (3m) but used it with the original charger. During gaming battery drops, with original cable it doesn't load but also doesn't drop, strange....
yeah, also bought some generic cable (1.5m long) but im using the oem charger/adaptor of nvidia shield tablet, since i broke the tip (micro usb port) of the oem cable.. there is a noticeable slowness in charging.. so, with regards to charging time, it's not always the adaptor itself, you can also consider the cable..
I had similar experiences using other devices.
I recall reading recently that there are estimates that *more than* 50% of USB cable manufactuered in 2014 were fakes. The trend was not going down - who knows, it might be 60% in 2016 :|
I use the app ampere and tested all my cables and chargers and sound that some cables would max charge at 150ma, and others at 2000

Ampere doesn't work with the shield tablet.
I tested with the shield tablet k1, marshmallow update. Just always showed 0mah. I put up a review explaining it, but the developer simply flagged the device as incompatible rather than trying to fix it.
I have a usb detector device from amazon tho, and I get 1.2 to 1.8 amps with if I use my galaxy s5s charger. Oddly out of the 4 different ones i have, thats the fastest. I read it supports quick charge 2.0 so I gota fancy charger with that that does supports it, 2.1 amps.. But it actually charges much slower then the samsung one - Yet chargers my actual S5 at the same rate, so I just swapped the cables and leave it like that.
PS: Was charging MEGA SLOW no matter what before I did this fix:
chmod a-x logd in terminal emulator.
(This also greatly enhanced battery life)
Also charges much slower with screen on.

Actually, ampere is working with the second update for the k1. You can get it from the thread here at xda if he hasn't fixed it in the play store yet
