Just got a griffin powerjolt micro, comes with an ipod cable so you'll have to use your own, but it charges the streak up a treat
Think it was 12 pounds from amazon.
It's designed for iPads, which need 2 amps, it's rated for 2.1 amps. Charged from 30 to 60% in 20 mins while using gps.
Hope that's useful .

For battery life is better to charge with low amps and for a long time. I would prefer ,not to use a charger with more than 1A
i got myself te belkin 1A charger. Should work good I guess.
As mentioned in the other thread, both these two work just fine :

$6 or $2 including free shipping worldwide. You'll need the Streak's USB cable to connect it.

The car charger does not force power into the phone, the phone draws what it needs. Using a power supply with a higher Amp rating means less strain on the charger not more power than is needed going into the phone.
Sorry for my bad English, I guess you do not understand what I mean.
You're right that the car charger with more amps does not force more power into the phone (I do not say that),but if you use a charger with more amps , charging time is less. The battery prefers long time charging with less charging amps. In fact using less charging amps ,the battery allowed to load more power (a little bit ). You can try it by using a USB port of yours computer to charge the battery.

Maybe it's just me, but what you are saying is exactly the same thing.
If the charger isn't forcing more power into the phone, then the charging time will not change. If the battery is receiving less current then what it was designed, such as a low powered USB port, then it would take longer then normal to fully charge. But once the charger puts out the amount of current that the battery will normally draw, the battery will only charge at that rate. Increasing the current beyond that amount will not speed up the charging time or push more current to the battery.

Anbuch is trying to say that the battery will last longer in the first scenario - the longer, slower charge from the low powered USB port.
Quicker battery charging does degrade the cells in less time - if you were to always use a 500mA charger, you would get more life from the battery than if you were to always use the stock 1000mA charger.
You can pick up a replacement battery from eBay for $10, so none of this really matters - when your battery wears out in 18 months, just buy a new one.
Nomgle ,thanks, this is exactly what I wanted to say!
I just gave an example with a USB port. In fact a USB port and a stock 1000mA charger are save enough for the battery of a Streak (1530mA). I just wanted to say : Do not use 2100 mA charger

This will "kill" the battery very soon
Some battery reading:
Understanding lithium-ion
Charging lithium-ion batteries
How to prolong lithium-based batteries
From the last page linked:
[FONT=Arial, Helvetica, sans-serif]Generally speaking, batteries live longer if treated in a gentle manner. High charge voltages, excessive charge rate and extreme load conditions will have a negative effect and shorten the battery life. This also applies to high current rate lithium-ion batteries.
Not only is it better to charge lithium-ion battery at a slower charge rate, high discharge rates also contribute the extra wear and tear.[/FONT]

Sent from the phone killer of ALL phone's, Dell Streak!
this has been real hell finding information about whether this http://www.ebay.com/itm/Powerocks-p...y_Chargers&hash=item3cc55ca8b0#ht_4645wt_1163 is compatible with my Motorola defy+ (note custom roms, Switching from time to time, Currently on WIUI ICS) and other information such as how long does it last and etc.
has anybody used this?
is it worth the money and how does it translate to battery % on my defy+.
any other feedback?
and maybe other recommendations (with that price region)
and is there a thing like this that uses AA batteries, if so, how many will it take to charge my Defy+
thanks ahead
EDIT:
what's the proper name for that thingy? because this thing has wayyyy too many names,
power bank, external battery, portable charger, portable battery, extra battery. and many many many more!!! this is why it's complete hell finding information.
what's the real and most proper name for it?
Just a single word 'AVOID'
i don't usually like to be disrespectful, but.
you sir, have convinced me with your long list of arguments and good points of reason to support your advice.
could you please explain, why?
Ok. Here it goes.
I have used these chargers long back, I think around a year back. It barely charges 15% of your mobile battery (I was using a Samsung Galaxy Apollo at that time which had a 1500mah battery) with a single AA cell which I think is totally not worth.
I hope this is enough for you to get a fair idea
so, you're saying that the Portable chargers that use AA batteries are bad, or are you saying all these portable chargers are bad and charge too little?
if you're saying that all the portable chargers are bad and charge too little, then i would have to say that it depends on how much mAh the charger can hold.
say i get the 2600 mAh charger to charge my Defy+ (think around 1700 mAh) when it's completely out, i think that i will charge fully at least once (say around 1000 mAh at MOST! is lost because of the charging procedure)
i'm only talking about the AA battery based chargers. I don't have any idea about other powerpacks as I've never used it.
1 AA battery for 225 mAh!?!?!?!? that's awesome!!! would be great for camping trips, you get like 12 AA batteries (or more, depends on how long you plan to be away from charging your phone normally) and you can even play in the evening or even watch porn if you got Data signal!
i'm still probably going for the normal one, and maybe i'll get an extra charger that uses AA batteries in-case i go camping somewhere.
can people please give feedback on whether it's good enough? why are there only 2 posters?
I think that it works just seen a duracell one in a store near me wich holds 4 AA batts, i think on buying it and fillit with some 4 NiMh AA acumulators rated at 2700 mAh each, just think about it thats 10800 mAh in a portable charge, that will charge my Defy battery at least 5 times even with an extra burning that the charge does.

NiMHs are 1,2V which means, 2700mAh hold 2700mAh * 1,2V= 3,24 Wh which is the same as 11,664 kJ
The Defy battery holds 1500mah at 3,7V --> 5,5 Wh = 19,98 kJ
Taking efficiency in count you might be able to load your Defy with two fully charged NiMHs once, but i`d rather expect that two are not enough.
As for the that eBay-offer: The voltage is given as 5,1V. With 2600mAh that would mean 13,2 Wh. But i rather believe they are stating the capacity at 3,7V for marketing reasons. That would mean 9,62 Wh. That would allow you to recharge about one and a half time.
bump?
So someones after advice on portable power when away from the mains?
Ive been using a New trent imp1000 to keep things going, its a li-ion rechargable powerpack with a capacity of 11000mah and it keeps my Defy going for 4 days.
I also have a total of three batterys for my defy, and a universal li-ion external charger, called a cam caddy, although its designed to charge camera batterys from a 5 volt supply it also quite happily charges up the battery for my defy as well.
So for extreme use i can have a battery in use in my phon, plus a spare with me, and back at base ( or just overnight) a battery on charge in the cam caddy.
If im in an area with access to mains i will take the imp1000 and its charger to top up where and when i can.
I also have a universal USB charger with swapable plugs that fit all major power outlets worldwide.
And to top it all off a USB AA battery charger that will ( slowly) charge up 4 AA batterys form a solar panel, or from a USB input ( faster) , or output 5V through the USB out put port.
This little set up has kept me going for 14 days with no access to mains power ( except for a few bits here and there - 20 minutes at a bus station/railway station and so on) , keeping my phone going (defy) a high powered AA cree LED torch, a camera ( via spare battery+cam caaddy) and an mp3 player. the trick is careful battery management - on the defy turn off everything when not in use, except the ability to receive calls and number your batterys for ID, and the same for cameras etc etc.

i think 11000 mAh is a little too much for me, it may be good for camping trips and etc, but i don't think i'm gonna buy something that (probably) big and (probably) expensive. most of the use of the external charger will be when i'm out with friends for a long time, or say after school i spontaneously decide to go out with friends before getting home (unfortunately a 1 hour drive from friends city to mine) so i need an a portable charger so i won't get bored on the way back, my battery lasts a school day, if i go somewhere that is not home after school, it won't last.
about the extra batteries, are those original from motorola? if not, are they as good as the original? are they worth getting?
The batterys are official motorla ones, as i b ought a cheap un official one and that had issues ( wouldnt show the charge level on the defy )
The battery pack is a "new trent imp1000" which costs £30 from amazon.
I also have a dock for the defy in which my phone usualy sits, at the back of this dock is a slot for an extra battery, left overnight this will charge both my Defy ( with battery inside) and the extra battery in the slot, this is plugged into a dektop pc where some of the USB sockets are still powered up ( giving out 5v) even when the desktpop p.c is off

Guys,
If you really want true power on the go, buy a YOOBAO power pack, the 11200 mAh one.
It is really a beast and is really charging a defy several times before going empty.

Yes, all iPhone compatible USB-Chargers are compatible to our Defy and other new mobiles.
Why? EN_62684: Common External Power Supply (EPS)
Why would I use Li-ion instead of AA Cells (NiCd,NiMH or NiZn)?
Higher Energy Density!
Another benefit of Li-ion is the discharging charakteristika (sorry for german captions).
So yesterday I bought a 2.0 charger off of amazon with the choe brand name. According to the ad it works with nearly every android phone, including the HTC one m8. For the past year I have been using a charger from my last phone which was a crappy flip phone and thought nothing of it, but I am wondering does this charger truly work?? According to app "Ampere" it is much slower. Also, I've read reports about phones heating up and that's what mine did last night, is that normal? How long should it take for me to full charge my HTC one m8?
It will heat up, that is normal. It'll use most of its 2.4A between 20 and 70% and then slow down. Your total charge time shouldn't take more than 1 hour, and make sure you're using the supplied cable.
Thanks for the response! So if it doesn't charge 1 to 100 in 1 hour than is something wrong? Also will a charger like this have any effect on how long my battery lasts? My last charger for whatever reason was for my last flip phone believe it or not, I never bought a new one.

no I wouldn't say that.
my 2.0 QC will get it done in about 1-2 hours compared to the 3-5 or so it took with stock charger.
0-100% will take more than an hour. I've timed mine a few times from 0-100%, not using the phone at all and in airplane mode waking it up every 5 minutes to check percentage, volts, and charge rate using Gsam batt monitor.
Comparing the two chargers (OEM HTC QC 2.0, and original HTC charger- which I believe is QC 1.0) the QC 2.0 is definitely faster. Even though there is nothing on the phone telling you it is using the higher wattage charging mode, it is. So, 0 to 100% using HTC's QC2, usually takes around 1:20 minutes if I remember right. As in the other post, it starts out rather slow to around 20%, then kicks in to high gear until around 80%, then slows back down all the way to 100% so as to not overcharge the battery and harm it. It really is amazing the speed that it charges at. It does get rather warm, which is normal, but shouldn't hurt the phone.
Now, completely draining and recharging these batteries frequently is not good for them and will decrease the useful life sooner. Keeping it somewhere around 80 % is ideal but realistically not practical and the manufacturers know that. That's why they build in overcharge circuitry protection so leaving the charger on all the time "shouldn't" harm the battery. Draining it down to zero and doing a full recharge cycle on it frequently WILL decrease the lifespan. The batterie's useful life is basically determined by a finite number of charge cycles.
There's tons of info on charging and batteries out there if you are looking for more reading too.
Anyone heard of the brand Auzen? It's popping up alot on aliexpress and around asian market. Not too much reviews yet on that brand.
don't play with quick chargers .I bloated my m8 batt once trying it .it charge at 2.4a .our device max is 1.5a.
If you insist using it then don't full charge with it n monitor closely .
That's impressive, I use a QC2.0 car charger, I use a variety of wall chargers that run from 1.0A to 2.3A at 5V.
So far, my battery is still very happy.
Sounds like you got a cheap knock off charger or your battery/charging circuitry was damaged/faulty and/or your ROM/firmware weren't proper, for that kind of damage to occur.
I don't think Ampere works. I once did a test (last month) and had 6 different USB cables and I wanted to see which was the best, every time I used one I got a different reading, from 200 up to 1600. Even using my Anker Quick Charge 2.0 I only got 400 so it stated.
I have been using Aukey QuickCharge 2.0 and gives pretty decent charge times.
I have a QUICK Changer 2.0. works great.. have some tips...
You know there is some colors on cable conectors ends you have to choose the right one..
- If the cable is not a quality one can result to slow charging.
Black ----- 1.0. most in stock phones
White------ 2.0. the right for fast charging...
The time on reaching 100% on battery,well Quickly charger 2.0 will reach 80% on your battery fast and it will change the next 20% slower...
There is some app in playstore can help can see the amperage live in mA..
Connect your charger to get the battery charging current or disconnect it and get the negative discharging current... and you can see your battery charging current mA is constantly changing because even on charging phone still using current (negative discharging current) and this is always changing.
On my case I see higher mA reading only under really low battery...
I have a problem with my m8 and aukey 2.0 quick charger....
After firmware update to 6.12.xxx.xxx mm , the app ampere tell me max 1600ma before update its tell 2000ma .. Its a bug or a feature of the new firmware base...??? I have cyanogenmod 13
Im using the same aukey 2.0 quick charger. Works perfect.
M8 is 1.5a max .if you use 2.0a logically you're overcharging it. Just wait for it to get bloat n replace the whole bat. worth it ?
Hi, i just wanted to say something. After many bad chargers i bought, i found the Nillkin chargers (2Amps)and Nillkin cables (2.1Amp) the best and best quality. I am always testing with good Usb voltage tester and it can charge up to 1.5 amps max on M8 and on LG G3 1.8 Amps. As long as the charger is 5.0V, amps can variate and it doesnt hurt your battery, it just charges slower or faster. In my case its charging 1% per minute on both phones. It doesn't matter if the cable is black, white, green... cables must be thick, around 18AWG that support high ampers which mean faster charging. thin cables are sh!#. And for car i also found the Scosche dual charger great for every device with Nillkin 30cm cables and Kenu airframe holder.
You can use 2.4A chargers on M8 without problem as it will only receive 1.5amps.

I'm using Anker PowerPort 1+. It's very good and you can use for iPhone iPad & almost Android devices.

That logic is incorrect. The phone will only draw as many amps as its rated for (1.5 amps) regardless of what the charger is rated to supply. Think of the charger amp rating as the "maximum it can supply" instead of "what it will always supply".

I purchased a current, voltage, detection tool http://www.amazon.ca/gp/product/B00NNGK4QS?psc=1&redirect=true&ref_=oh_aui_detailpage_o05_s00
made by SainSonic.
Okay, I know this isn't a fluke meter quality and standard, but how come when I charge my phone from i.e. 20% battery capacity left, to reach a full charge the Sainsonic USB tool reports back with a supplied mAH of approximately 1500mah to reach a 100% charge.
Are we to assume the battery capacity supplied by motorola for the Nexus 6 phone to be rigged or false? Is this another one of those cases, where your mileage will vary b.s.
I know the USB detection tool is not a Mil Spec device, but, how can it report back this off of factual value or reading?

2nd test
OK, so I let the phone on, til the phone did it's own shut down. I even rebooted the phone into Recovery mode, where it eventually powered off, 2x. I know this is bad and not recommended for a battery, but I wanted to try to deplete the battery completely, and using the turbo charger, charge the phone and get a mAH consumption to refill the battery.
From an empty charge to maximum, I recorded 1825mAH. I am unsure, if by TURBO charging the phone, whether I am not registering a true milliamp draw and count. My last test, will take place doing the same thing, but using a standard NON turbo charger to see whether or not this reports a difference or not.
Cheers
That meter does say that it's for between 3 and 7 volts which is pretty much saying it's made for a standard 5V usb spec current. The turbo charger uses voltages of 12, 9 and 5 volts to accomplish its faster charging speed and the charging voltage only goes down to 5V once the battery is almost full somewhere like 75% iirc.
Though it also wouldn't surprise me if the turbo charger doesn't turbo charge when running through that meter. Might check and see if the phone charges any slower when you switch to the normal charger test.
While Charging, the USB meter does show it's outputting voltage as well. AND, while charging I do have the phone using an app like Ampere so I do see that it is in fact indicating TURBO mode. But logically, the phone does complete it's charger in under 2 hours, hence it is charging very quickly = same as turbo charging.
1) It is in fact Turbo Charging. 2) The outputting voltage, even though is variable (from 5 to 9 volts in the case of Turbo Charging) would only relate to varying the mAH per / Sec if you will, from a quicker or slower "Consumption" (i.o.w. if it is quick charging, the rate of supplied mAH is faster than slow charging, so the total amount or capacity of charge is the same, it is just a matter of how quickly can you refill the empty bucket of water, with water).
I am using the Pure Nexus Project Nexus 6 Rom, flashed with the latest Radio, and I am extremely happy and very stable build (so much so, I even sent beans some props and thank$you donation). What I am disappointed with (even with previous roms and build from 5 all the way to 6) is the battery capacity (I loved the Turbo Charging so much, I did away with carrying a battery bank and purchased a 2nd Turbo Charger for the office). I did not purchase the phone new, but did get it in an almost new state (purchased from the typical, "I got to dump this just came out phone and get the latest released phone" type of tech junkie). FWIW, it is the 64gb model, and about 6 months old (I have the google bill showing the manufacturing date and sell date). I can't say I am impressed with the overall battery capacity of this phone, but it is designed to get me through a day 90% of the time, so I am never really worry free, it simply not a tank like some other monster phones that I have had (I like smartphones with a minimum of 6" of screen, my previous phone was the Samsung Galaxy Mega 6.3).
I will be honest, I have always been a battery junkie from my days as a Radiocomm R&D department tech, so I have a carryover Battery Analyzer (5K $ piece of bench equipment) that I can use for most of my battery related equipment (from battery powered yard tools, commercial grade walky talkies to household products like cordless home phones). But things like cellphones would not work, because I do not have the correct adaptor that has the correct resistance type, delta voltages, and connect-ability. In most cases if I jerry rig something (like I was curious to know what the capacity of an Energizer D size battery was compared to a Duracel D size Alkaline Battery capacity was, I could read the output mAH capacity from either battery and know which does really last longer) I can get the output capacity but cannot perform a 3x count battery analysis (which basically performs a full charge discharge 3 times in a row and spits out the 3 capacities back) which in fact I would NOT do on a Lithium battery for obvious reasons.
Got this external USB battery at a sale price. This model from Choetech packs in a few surprises.

This is the only battery pack I’ve ever seen that can recharge over both microUSB and Lightning, meaning you should always have a charging cable handy. It also supports Quick Charge 2.0 input and output, meaning you can recharge the massive 15,600mAh cells up to 75% faster, and get that juice into your phone with minimal delay. $26 is a bit of a premium for a battery this size, but I’d say the features make it worth it.

Yup nice for this info. it's really good.
The direct charging technology that was till date used for charging the mobile and other gadgets have been slowly replaced by this indirect charging that offer utmost convenience at the time of traveling or commuting. It has two-way charging capacity that allows its battery to get charged from an external power source and later the same battery power is used to charge another device. no power bank utilizes its capacity to the fullest which means if you use 12000 mAh battery then it won’t charge 6 phones with 2000 mAh capacity as there is some amount of power loss during transfer that cannot be ignored.
high capacity one's take much time for charging So, go for optimum capacity that usually triple to phone battery capacity.
Power bank batteries are available in two variants Li-Polymer Battery & Li-Ion Battery. Familiar is Li-Ion battery because of lighter, sleeker, and portable to carry and better battery backup. Charging time depends on plugs, are 1A or 2A, Usually 2A charge quickly but it should support by the device.
