External Battery - Dell Streak 7

Is there such a thing as an extended battery, external, for the Streak 7? Something in the 2700 to 3700ma range?

Does the Streak 7 use the same battery as the 5" Streak?
Related to the above: I can't seem to find any information of what kind of battery the Streak 7 uses. Could it be the same battery as the original Streak (5")?

The streak 7 has a fixed battery and therefore the are no user replacements possible. The streak 5 has a normal battery cover. There is no battery cover on the S7.

I know it has an internal battery. I'm thinking an external battery pack, not a replacement battery. Something like is available for many laptops. Something that can be plugged into the charg port on the Streak 7 and extend its run time.

Ah, of course. Well, just about anything that has a USB output would work, here is one from Amazon:
http://www.amazon.com/Portable-Battery-Powered-Emergency-Flashlight/dp/B003M9Z5F6/ref=pd_cp_cps_2

So from what I have read so far, there is no battery replacement for the streak 7? My streak 7's battery has gotten worse for some reason and I was hoping for a change. Does warranty cover replacing the battery inside?

It can be replaced at the factory. I'm not sure about the warranty. If it is really bad, it may be considered a faulty battery and be covered. But of course they cannot be responsible if the battery has simply been used a lot and is depleted.

External battery
one would work and last for a good amount of time.
check out amazon the have a battery backup that seems idealmade by isound.

I'm thinking about getting one of these:

16,000mAh would be nice to have on hand.

I would check the output voltage. The Streak 7 wall charger puts out 5.35 and charges fine. Standard USB is 5 and charges so slow it looks like it isn't. It took 9 hours for my streak 7 to charge from 60% to 100%. When in regular use, it will discharge even plugged in on USB, just not as fast. If this is following USB standards and putting out only 5vdc, you may be disappointed with that, or any, battery pack.

It's not the voltage that is causing the slow charge, it's the amperage.
The Streak is similar to the iPhones and iPads in that it draws more than the ordinary PC or Hub USB port will supply. Normal PC USB ports are limited to 500mAh. Some hubs are known to supply 1,000mAh, but they're rare.
The iPad charger supplies 2,100mAh. The Streak 7 charger supplies 2,000mAh.
That's why the charger will charge up the Streak 7 much quicker than a PC or hub - roughly four times as fast.

I have a USB battery pack that provides 5vdc at 2700ma and when my streak 7 is plugged in, it does not charge after being plugged in for 20 minutes. But the streak battery gets down to 4% and holds for 3 more hours before totally dying. It's the voltage of the standard USB that is the biggest problem for an external power source. Normally u can plug a device into a battery pack like mine and recharge its battery. I use it a few times a week to recharge my phone. But the streak 7 needing 5.35 vdc means the best u can get is keeping it alive on an external source, but not actually recharge its internal battery.

I'm confused W.O.W. I was wondering where you got the 5.35v for charging the streak, so I went and grabbed my dell wall charger and my t-mobile car charger. The wall charger does in fact say that it is supplying 5.35v (at 2 amps)! (Sorry, I didn't believe you until I saw it for myself. )
The thing that I find very strange is that my streak charges just fine in the car with my T-Mobile Dell Streak 7 charger, and it only outputs 5.0v (at 1 amp).
So... I'm wondering why yours is giving you grief... Hmmm...?

How long does the Streak 7 take to recharge at that current? I'm guessing about 6 hours?
Sent from my Dell Streak 7 using XDA Premium App

I haven't had the streak do a full charge in the car. But on my commute I get about 20% top-up from a 35 minute drive. So that should be about 2 1/2 to 3 hours for a full charge.

Oh how I long for the days when companies follow industry standards. And for the days when companies wait to put a product out until it was ready. * Hey Dell, Samsung, HTC, Motorola, Barnes and Noble, how about a removable battery in the next series of 7" tablets*
So if we ignore the 500ma max for USB, and change it to whatever we like, we can cram all the current we like and still say it's USB? Ugh.
Thanks for the numbers
I'm gonna guess that the reason my battery pack only shows charging for 20ish minutes is cuz as it charges the Streak 7, it discharges, and after that time the voltage has dropped enough to not register as a charge, but since the electrons are still there, the tablet will consume them. In a car, the 5vdc from the charger is maintained by the cars charging system, so it never drops below.

That'd be my guess too.

It's the amperage for sure. The device will draw as much as it needs up to the max amount of amps the charger is rated for.
For example: If the device pulls up to say 750mAh when charging and you only supply 500mAh then charging will be slower. If the device will only pull 750mAh then throwing 2Amps won't do any better than a charger that will supply 750mAh.
How much draw the device will actually pull I do not know. Since the supplied charger is rated up to 2Amps then odds are the device will pull just under that.
You can get a high Amp car charger/usb adapter at RatShack: Model: 2730-501 | Catalog #: 270-057. I like at least 2Amps for my devices. This one is 2.5.
I mounted a home dock in my car and power it off of this adapter/charger. It works like a champ.
DO NOT throw more voltage at the unit then what is listed on the wall charger.
More Amps=Good
More Voltage=Smoking Tablet

this is the one im planing to get it has 5.35 v

[Q] USB Li-Po battey does not charge Streak

As the title. Oddly the streak will be powered by it when the battery is removed (it shows the "battery missing" screen.
The battery I have is a third-party Chinese thing I got from the amazon market. It seems to do the job for other handsets I have (HTC Raph, Couple of nokia handset)
Is there anything I can do to make it work?
The USB input on the Streak requires 1000ma @5v to charge so many of the chargers on the market won't work. I just picked up a Just Mobile Gum Pro 4400mA from Amazon and it seems to work fine. I haven't had a chance to check it out yet other than to make sure the Streak shows "charging" when it's plugged in.
Here's a link.

Phjnky, have you tested it further? How long does it take to charge the streak and how many charges can you get out of this?
Does anyone else has any external battery to recommend?
Found Duracell CEF23-UK on amazon which seems like a very good idea. But it only output at 1.4v, 360mha which is useless for the streak. Does anyone know anything similar that can charge the streak?
The mobile gum pro works really well. Went on a trip and used it to power and recharge the streak. I dont recall but it seemed to recharge maybe twice from around 25% or so. It does charge rapidly about like the wall charger but I was using gogo inflight Internet and listening to Pandora, reading blogs etc while it charged. It kept the Streak going all day while on two long flights. I never fully ran it out of juice but got down to one bar.

I don't have the charging dock so can't comment on it.
These two batteries look the same to me except the $5.80 one seems to have a yelloew sticker with a wholesales vendor's name on it. The $9.50 one shows an extra "Built-in safety and protective circuitries" feature in the description.
I have a different pack, SKU 57931, from them. It comes with a bettery but I am not sure if it is a $5.80 or $9.50 one since there is no serial # on the battery. After initial full charge, Streak uses about 25% per day. I have very mininum phone usage (few quick calls/texting/WiFi. I don't have 3G service).
Even it is a $5.80 one, it seems to be working fine for me.
BTW, it took a while to finally receive the shipment in US. (about 4 weeks after placing the order).
I have the charging dock. It works very well I use the streak as a bedside digital clock
at night while it charges. Good value as mine came with all cables and power supply.

Make sure you buy 3 .
I dont own either, but I do have a usb cable coming from them in a few days, as well as a zune cable amongst other things. Hope it isn't broken.
I got a USB cable from DX and it is very problematic - it causes the Streak to crash and/or drop its connection. I have a number of cables, both original Dell ones and aftermarket ones purchased from eBay, and none of these exhibit the same issue.
I have bought a LOT of stuff from DX over the years, and it is extremely rare to have any problems, so I guess that I just got a bad cable, but you may want to test yours carefully when you get it just in case there is a bad batch out there.

When I have the Streak connected to my PC (or to a USB power outlet) using the cable that I got from DealExtreme, it frequently reboots and/or loses the connection to the PC. This only happens with the DX cable (I have 4 genuine Dell cables plus 2 bought from eBay and none of them have this problem).
There is obviously a loose connection or short inside the cable.
As I said, I don't want to put anybody off from buying from DX, as I find it's very rare to have any problems with their items.

Took a few weeks to get it but I finally got it. The dock is great, the only complaints I have is that the AC charger is only EU (thankfully I had my AC adapter from another Mini-USB device), the car charger can be easily disassembled because it's not glued, and you can't charge a spare battery AND your phone at the same time through AC power alone... if you want to charge them both at the same time, you must also use the USB adapter and connect the dock to a computer. There is an LED that changes from Red to Blue, depending on what it is charging at that moment. If you have your phone docked, it will charge the phone and the light will be Blue. If you insert a spare battery to be charged, the light will change to Red and only the spare battery will be charging.
I've been using the $5 spare battery for 3 days now and I must say it's as good as the original. Let's just see if it holds a charge after a few months!

Charging Nexus 7 - travel charger

Hi all,
Can I please get some advice from someone who might know better than me. I have been using the following charger on my travels to charge an iPad and Samsung galaxy nexus at the same time:
http://www.amazon.co.uk/Skross-Char...?s=electronics&ie=UTF8&qid=1342643375&sr=1-23
I've just plugged my nexus 7 in on its own and I get nothing.
I didn't think the nexus would need a higher amp than the iPad? The Asus plug that's charging the nexus says its 2amp and the travel charger says its 6.5amp. Am I being amazingly blind or stupid here?
And if I need a new travel charger for my trips into Europe can I have some advice on what to buy before I buy something else useless.
Thanks all!

Nexus 7 trouble with other chargers
I see the same issue.
The Nexus 7 charger lists: Output 5.0V===2.0A, Nexus 7 will charge.
iPad 2's charger shows: Output 5.1V===2.1A;Max 10Watt, Nexus 7 will not charge,
Philips universal charger: Output 5V===2A; Max 10Watt, Nexus 7 will not charge.
Blackberry phone charger Output 5V===500mA, Nexus 7 will not charge.
Blackberry phone charger Output 5V===700mA, Nexus 7 will charge.
To answer the OP: The Amazon product page clearly states Output 5.0 VDC / 1000 mA max. N7 needs 2000 mA (2A). Derping in public again. Don't mind me. :silly:
To add to the list:
Samsung Galaxy Tab 2 7.0 Charger: Output 5V ⎓ 2A; Max 10Watt, Nexus 7 will charge.
XtremeMac IPU-IH2-11: Output 5V ⎓ 4.2A (2.1A per port); Max 20Watt, Nexus 7 will not charge. (Galaxy Tab 2 7.0 charges though.)
The N7 seems very picky about chargers, unfortunately. My XtremeMac is now powering my charge cables for my wireless mouse and keyboard, freeing up 2 USB ports, so not all is lost I guess.
I have a 2.1a car charger, but it doesn't charge it.
http://www.amazon.com/gp/product/B007TV88F2/ref=oh_details_o00_s00_i00
EDIT: Interesting. It will not work on the car charger wiht my "charging only cable" which has shorted out datapins to register as an AC source. But, it does charge on a normal USB cable.
I have a tf201 charger (here i refer to the usb block, not the cable) that seems to super charge the nexus 7, that is to say, very fast. The tf201 charger is 18 watts. Also, I have noticed my usb 2.0 ports on my desktop will not charge the n7, but my usb 3.0 ports will.

I started a related thread asking if anyone has examined the proprietary aspects of the charger here:
http://forum.xda-developers.com/showthread.php?t=1780211
Basically, we should be able to build (or eventually buy) some type of adapter to enable proper charging with any 2A charger after we figure out exactly what the charger is doing. I wouldn't be surprised if all Asus tablet chargers already worked properly without an adapter.

This answer is clouding up a lot of legitimate discussions. The current rating doesn't matter to this conversation at all. If the current is above 0 the device should show the charging icon. If not, there is some other problem.

You are correct that my remark about the OP's charger's current was not a valid point. I have stricken it from the record.
That said, some serious weirdness is going on with the N7 regardless. On the XtremeMac charger the N7 will charge. But incredibly slowly, and the battery status reads as discharging, even though the line on the battery graph is rising. I don't even know where to begin in trying to explain that.

Agreed. I bought a pair of dual 2A chargers and neither of them will charge it at all (no charging icon). I tried shorting the data lines and still nothing. The dual charger that came with my Razr will charge it slowly (about 16 hours from 0 to 100%). My old 700ma Blackberry charger works just better than anything other than the OEM charger. Frustrating and I don't want to keep ordering different chargers with my fingers crossed.

I don't know what a XtremeMac charger is, but I'm assuming it's for charging an iphone or ipad or something? the Nexus 7 and the apple products don't share the same charger design, so the Nexus is probably only drawing 500mA while charging from it.
You can also add the MonoPrice 8856 charger to the list that do not work with Nexus 7

The Asus transformer prime which is a USB charger with proprietary cord also has something weird. Other USB chargers with the same power specs connected with the Asus USB cable won't charge the prime. Or they charge where it literally takes like 24 hours to reach 100 percent.
There's something different in that Asus power plug on both devices it seems.

I'm not sure what It's output is but the standard Verizon branded micro usb charger does a great job charging my N7. I think they for sell around $30 in the VZW stores tho.
The 1.0a charger that came with my LG Revo works great, almost as fast stock. I bought 2 extra of that charger on amazon about 9months ago for under 10 for the pair.
Also the charger for my old Droid (.7a iirc) works as well, but it's slow as hell with the screen off, and barely keeps up with just web surfing.
The Charger with the HTC Desire seems to be charging - though slowly as its a 1A charger.
Does anyone know whether the International Samsung Galaxy S II charger works?
The TF101 charger works great, and fast too - about 1% a minute.

Nexus 7 is apparently very finicky regarding what chargers and what cables will do the job - some of mine work (e.g. $4.74 Motorola http://www.amazon.com/gp/product/B004EYSKM8/ref=oh_details_o05_s00_i00 ) some don't (Griffin iPad charger for instance, which is a powerful charger and works for Everything else I've tried)
Along the same lines, if you have it attached to a generic car charger and are using it for GPS, the charger barely keeps up with power use.
Yes it charges slowly. Yes you have to use the charger that came with the unit.

That's better then my SGS2 phone. I had about 20% left on it, but needed to use it as a GPS on a business trip. Plugged it into a car charger, and loaded up Navigation. The phone indicated charging, but the battery level kept dropping (albeit a little slower). By the time we got to our destination (~30mins away) I only had 7% left.
Crazy.
Would the Nexus 7 charger be OK with my Galaxy Nexus or will there be issues? I don't need two chargers at the same time.

I charged my Gnex with the N7 charger two nights ago, had no issues but i don't know if it is safe.
As long as the voltages are the same, and the amps are = or > than what the device needs, you should be OK. The device will only pull the amperage it needs. Voltage is what needs to be the exact (but I don't think this matter over USB, since it's all 5v - matters more with generic A/C adapters). If you don't have enough amps, it could result in slow/failed charging, but too much doesn't matter.
It seems to picky with cables. I also used a longer USB I had lying around. I left it charging for 30 minutes. I came back and it only went up 1% I switched back to the cable that came with it and it started to charge it normally.
I'm not sure why its happening but its weird

tricky
The nexus 7 need "compatible" usb cables, i have one that is working great and it's for usb charging only, no data .
The nexus 7 battery is 4325 Mah so a 2Amp charger will charge the battery in a little more than 2 hours (calculate the 325mah over and add the standby battery discharging when you charge it while at ON)
So the tips are:
1. Find a good 2Amp usb charger
2. Find a compatible cable, try some no data cable or maybe usb3 or again try, try try...
Awesome Tablet
I picked up a 6 ft generic Micro USB cable from Amazon for around $2, and I've been using it to charge my Nexus 7 virtually since I bought it after it launched on the Google Play store, because it's much longer than the OEM Asus cord.
The problem though, it was hard to plug in, so I filed down the bumps [on the bottom of the connector, or, on the Nexus 7, the side facing you when you plug it in--because the N7's micro usb port is up side down ] a tad bit too much so now it's a little to lose. So sometimes when I adb into it, and move it a little bit, it will lose the PC connection [but never the charging connection] intermittently.
Also, it charges fine, except when I'm playing MC3, or Bad Piggies HD. With those apps, it will say Charging, but will actually slowly discharge [slower than on battery, so apparently there's not enough power to tread water, and it sinks slightly]. It's plays HD 720P mkv files fine [with MxPlayer], and stays fully charged at 100%.
Same thing here

My nexus takes about 7-8 hours to charge, and thats using the original charger that it came with. Used it now for a week without any improvement. Also my battery time with lowest backlight, gps off and so on is around 4-5 hours which feels abit low. wtf is going on?
Any usb charger should work.
The problem is the charge controler IC in the N7, it is REALLY picky with voltages.
My N7 OEM cord is a much heavier gauge then my NS or GN cord, on top of that the NS and GN cords are twice the length.
We had a really long thread on G+ about this, we even figured out the observer effect was screwing us when we had an ammeter on it.
TL;DR:
If the cord is too long or not heavy enough the N7 only pulls like 800mA (It can be less if the charger/cord is really ****, we had 300something mA with one combo)
The 2A OEM charger isn't 2A, but it's close enough.
microUSB plugs NEEDS to be 5mm or longer for them to mate in the plug properly, OEM is like 7mm
Some other crap I can't remember at 5am
So yeah, it's picky.
Use what it came with. It came with it for a reason.
Just got this in the mail from monoprice today and it's charging like a beauty.

That's because the iPad charger doesn't have the data pins shorted out to enable fastcharge . Easiest way to accomplish fastcharge with your charger, is to buy a charging cable (data pins shorted out, so it is not a data cable:
http://dx.com/p/usb-male-to-lengthe...for-samsung-i9500-9300-htc-white-100cm-207353
It even has the lengthened micro usb connector the Nexus 7 needs.
Or maybe better, buy this one, found in another thread here on XDA, this one is confirmed to work in fastcharge mode with any usb charger:

Good luck!

Yes I know, and that's the reason the iPad charger won't work on fastcharge.
You need to either shortout the data pins of the iPad charger, or use a charger cable with shorted data pins ( a so called charge-only micro usb cable) to make the iPad charger use full capacity (fastcharge mode). There are also cable adaptors for sale that will shortout the data pins for you.

Yep, that one works because it follows the USB standard rules, and not the Apple USB standard.
No iDevice (iPhone/iPad) charger will fastcharge an android phone or tablet without modifying the datapins or use a charge-only cable / adaptor.
The Blackberry Playbook charger is known to work
Get an HP touchpad charger if you can. I can provide empirical evidence that it will actually charge your n7 20 minutes faster than the stock charger. I posted a thread about it here some time ago. "Best aftermarket charger ..." Or something like that.
Plus, my HP touchpad charger hasn't failed to work with whatever device I've plugged into it - idevice or android.

I will suggest the HP touchpad charger for use with the N7... they work great and produce no noticeable heat when not connected... shows good efficiency.:good:
Check Ebay -= just did a quick search and got 131 hits anywhere from 8-20 USD. I"ve bought 2... one is firmly set to be my preferred travel charger for any USB device.
+1 Re: HP Touchpad charger
Someone did a in depth look at factory and aftermarket chargers and it came out way better in terms of current provided and cleanliness of power without spikes or dropouts.

Do I still need a aftermarket cable w/ the data pins shorted out? Or will this all in one package: http://www.ebay.com/itm/Genuine-HP-North-American-Power-Charger-FB341AA-AB-for-TouchPad-Cable-/251250614212?ssPageName=STRK:MESE:IT Do the trick?

That will do the trick - but you don't need another cable if you already have one.
I went with the charger without cable option and got 2 chargers for less than that price. Just have eBay sort the search results by price+shipping and optionally USA sellers only to find a better price without waiting for a slow boat from China.

Will using chargers not putting out the proper amperage cause any hard ware issues? Just curious.
Thanks

If the charger puts out less than the tablet needs then it will just charge slower (or not at all if it's really low) and if it puts out more than the maximum the tablet uses the extra will just go unused. Voltage is a different issue.

Having your device plugged into a USB 2 500mA computer port obviously charges slower then a 2000mA wall charger. It would be pretty faulty design if plugging your device into your computer would cause hardware damage.
Man, this really sucks, the Monoprice cable mentioned earlier in this thread is having the same issue I had with another micro USB cable, it doesn't seem to fit into the Nexus 7 snugly, it doesn't seem to go in all the way. (I hope I don't have a busted charging port), It doesn't seem to charge it at all, even with the stock Nexus AC adapter. I'm about to break down and buy the official Google charger again, even if all I need is a new micro USB cable.
I'm using 2 different monoprice cables, one in my car and one at home, and both fit well. Sounds like the port has gotten damaged.

So, I just decided to buy a whole new charger off Amazon. If that won't work and I determine that the micro USB port is busted, I'm not going to be very happy, haha. does anyone know if Google repairs them for a fee?
I use a Playstation Vita charger which seems to charge my N7 very fast. On the other hand, I've tried an old mobile charger also and the battery level goes down whilst plugged into it.
If under warranty and purchased from the PlayStore, yes, otherwise, if under warranty, ASUS.
