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.
it seems like motorola is a HUGE fan or proprietary cables, especially the v60 series flip phones.

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.

going to have to look into that dock cause i'm not to fond of the charger that it has. so the avg. use time is about a day, are you guys mod or heavy users(as you can tell i dont have mine yet ordered and waiting for it to show up)trying to get as much real world use info as i can
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.

Just a guess but I expect your need a bigger battery, like that in a tablet, to handle charging at 12 volts. As it is, I'm blown away by how fast this phone charges on the adaptive charger. Just wish I could get one for the car.

I have the Anker PowerPort 2 that has a max of 2.4 amps per port and a Nekteck USB Type C to Type A cable (that's tested and approved by Benson). When trying to charge, the max mA that I've seen is around 1550mA.
Why is that? I was expecting around the max of ~2400,mA
I actually ordered this exact combo on Amazon, curious to test it myself.
Are you using Ampere to measure? If so, before plugging in the cable, you need to note the discharging rate (some negative mA). Then plug in the phone and note the charging rate. You have to add the two numbers together to get the actual amperage from the charger because Ampere can only measure the overall system in/out amperage. So if you were doing something really intensive and plugged into a slow charger, you may see it say "Charging" but have a negative number!

I forgot to mention that stuff! Yes, I am using Ampere and discharge is around -150 to -300mA. The average discharge rate and average charge rate added together (around ~1800mA) still comes up quite a bit short. Hope the combo works out for you. Or at least confirm my findings.

Huh... I wish that Google engineer would clarify things. Myself and others have been discussing the Type-C spec over here and the documents seem to indicate that a Type-A to Type-C cable that has the proper identifying resistor would be limited to drawing 1.5A. I'm hoping I'm wrong.
Also, try measuring the discharge for a minute or two. I've seen mine settle in around -1000mA if I let it sit awhile. But then, I don't know if that's accurate...
Man, this is such a mess. I got an Aukey 12W / 2.4A Home Travel USB Wall Charger just to see if it there was something wrong with the Anker charger. Nope. The Aukey floats around 1600mA too...
For good measure, I used the supplised USB Type-C to USB A cable - same charge rate. Then I used the charger and C to C - that floats around 2700mA.
Are there any 2.4A chargers that actually charge at that rate?!?!
The USB standard for an in spec Type A to C cable will charge at 1.5A. Only a type C-C will charge at up to 3A. Please Google/search the forum next time before creating an OP. It doesn't matter if you use a Type A to C cable with a 5V. 4A charger it will only give you 1.5A by the USB charging standard. If you use a C-C cable you can get the Max rate

So for Benson's review of the cable, he says, "...you should be able to charge from a range of .5A to 2.4A using this cable." I guess he should've been the one to "please Google/search the forum."

Yes but he goes on to say in other reviews that the USB A-C standard dictates the output of the cable.
As discussed thoroughly in 2 different OP's which you can find below.
Here is a quote from @Elnrik
"No, when I say proprietary protocols, I mean protocols. Not physical wiring. As in "2.4A, which is negotiated over a BC1.2 protocol like CDP or DCP, is appropriate over the Type-A connector." and "By the way, the maximum current of 1.5A is defined by the BC1.2 specification for CDP and DCP, but in practice, a range of other current values are possible using Apple's proprietary protocol or other protocols that bump up the defacto maximum current with a Type A connector on one end up to 2.4A". ~ Benson Leung. The evidence of 2.4A charging on compliant cables is out there, I invite you to google it for yourself. Unless you wish to continue to willfully ignore that. Up to you."

The charger is rated for 2.4A.
Unless you have a crap charger it's got current limiting circuitry. Not likely ro damage it using it for its rated output.
I doubt I'll burn the cable up.
I have a MSEE so I know how power supplies and cables work.

The charger is rated for 2.4A.
Unless you have a crap charger it's got current limiting circuitry. Not likely ro damage it using it for its rated output.

The point I have been making is that the resistor in the Op cable is incorrect. This means the phone will attempt to pull 3A even though the charger/cable aren't rated for it. This would clearly cause an issue. I haven't seen any out of spec cable hold a 3A rating with the correct resistors and actually deliver it from a A-C cable. I'm nor saying your wrong I'm simply stating that this has been brought up by many people who are just as qualified. I've taken some EE course myself being an engineering student an all, but this doesn't mean I know enough to make a 100% correct assessment of the cable/charger situation. If it wasn't an issue we would see reports of chargers burning out so there is an issue somewhere

Yeah, I had a couple OnePlus cables early on - weeks before I had the 6P. When I saw that they weren't certified and could do damage, I stopped using them right away. Wasted ~$8 unfortunately.
Waiting for (more) legit reviews for quality Type-C chargers. Should be soon.

The Choetech was reported to deliver the specified 3A about an hour ago in the accessories subforum. You can check there with the member who has it under the 'type c chargers' OP
Will the USB type-C cables work with any USB port and USB wall charger? If I can get away with ONLY buying cables, that'd be nice.
Yes, if you buy USB-A (Legacy) to USB-C Cables. However, you (obviously) won't get fast charging from your other adapters.

So I need a "6P fast charger" for fast charging? Otherwise it's normal charging? Or will my N6 fast charger work (minus the cord obviously)?
Correct. The N6 uses Qualcomm 2.0 which is different. However, if you want fast chargers, you can buy quality aftermarket chargers (like Choetech on Amazon) for much less. Also, be careful on which cables you buy (a lot of bad ones out there) REGARDLESS of whether you buy A2C for normal charge from your old charger's, or C2C for new (fast) chargers. Again, Choetech's are good/aprooved, but there are other good ones if you search.
If you're looking to get the fastest charge, go with a C-C cable and premium Type C charger. This should allow 3.0A 5V of power delivery.
I just need extra cables at this point. One for my car charger and one for work. What cables off of Amazon would you guys recommend? Nothing crazy expensive..

I got this cable from Amazon, due to getting a discount. I use it at work with a 2.4a charger, and it has worked well so far.

Here is the the spreadsheet, so just go ahead and take your pick. It has pricing too, so you should be good to go with this.

Agreed, and the Choetech I reccomended (with Choetech cables) puts out 2.95A, which is about the same as you get when you measure the Google charger.
Choetech cables were tested and approved by a Google Engineer:

These are what I use. But any in the above spreadsheet will work.

These have great reviews it seems.
I see a ton of options...I obviously need USB A to something.. Which should I pick for the other end? Stupid question, new to USB C... I see like USB A to USB C .5mm, 1mm and 2mm or something. Just want to get the right one.

Just go with any of the C-A cables on the spreadsheet that are approved. You can use any of your qualcomm charges to do 2.0 amps, but will need a 2.4A charger to get 2.4A current.
If you want a 3.0A charge go with a C-C charger.

That's just the length of the cable. It has it in meters =D

Oh, that's weird. Usually it's in feet. I was thinking mm for some reason.
I would use caution in purchasing USB Type-A to Type-C cables.
This is a collection of reviews of products sold on Amazon which have been tested for compliance with USB specficiations: https://plus.google.com/u/0/collection/s0Inv If you find a cable you wish to purchase, I would recommend researching it in that G+ collection, here on XDA, or (failing all else) check the Amazon reviews to see if someone tested the cable to ensure it is compliant with USB specifications. If you can't find that information in any of those locations, I would probably skip purchasing it. (BTW, someone in this thread has already recommended a non-compliant cable to you - so do yourself a favor and do your homework.) Just in case you think this issue is being overstated, please review: https://plus.google.com/+BensonLeung/posts/Cq8DuigqhzG and https://plus.google.com/+BensonLeung/posts/HzkGqnWcyYM.
I would recommend the following cables, as they have been tested and are good (and/or I own one myself): http://amzn.com/B010VFFU1W, https://store.google.com/product/usb_type_c_to_usb_standard_a_plug_cable, http://www.monoprice.com/product?p_id=13002
Enjoy
Edit: The Chotech cables you seem to be reviewing are compliant and safe.

I didn't want to put that cable on blast, but yes that cables outer appearance seems to be the type that Benson had some extreme issues with.
Please go with the tested types, as there are various sources that will provide you with compliant cables.
I up vote this post!

I assume that you're referring to my post. Yes, I have found a few reviews stating that it isn't compliant and I know I may be taking a risk. Unfortunately, I wasn't able to find that cable on Benson's list. I got it because with the discount, it was free. I don't use it very often, but I'll keep an eye out for anything unusual while doing so. I also didn't say that he should go for that cable, I was just sharing information about one of the cables I have.
At home I use the stock power adapter and cable, and in my vehicle a Nektek branded one found here. This particular one I don't believe is on his list, but two others are, so hopefully this one follows suit. It does rapid charge, which is nice.
I'll update if anything runs afoul with my Nexus 6P and LaoHe cable pairing.

Try using the CheckR app. https://play.google.com/store/apps/details?id=net.mderezynski.checkr
It will let you know if a USB-C to A cable is good enough to use and it will work with the 6P/5X.
