I'm currently using a regular usb cable to charge my phone directly from my car stereo while driving. The problem is that it takes close to an hour for the battery charge to increase 10% when I'm streaming pandora through bluetooth and using the phone's GPS. I'm assuming that the usb port in my stereo is only capable of putting out 500ma, if not less. Curious to see if anyone knows whether a DC to micro usb cable would give me a faster charge (1000ma). Thanks in advance.
BEst one ive ever used is the official palm one for the pre or pixi. Completely charges the evo from dead to full in about an hour while on the road on a call via bluetooth. Seriously good, verified a while ago on the precentral.net forums that its 1000 mA. They are only like 15 bucks at best buy, or maybe even less on amazon.
Go to amazon or google and search for 12V 1Amp USB charger and that should give you exactly what you need...I use a 1Amp charger for all my devices and works just fine...1 thing to note, that if you have time to use a 500ma charger, let it do it, a little bit slower charge will extend the life of the battery(not necessarily run time, but the length of time the battery will hold as good of a charge).
I use the one below. Works pretty great..5V/1A, exactly what you'd need. The thing says iPod, but it can be used for any USB charged device. An extra nice feature of this charger is that it sits nearly flush with the dash of your car

Cool, thanks for the responses guys. I ended up going with the palm pre charger from amazon, a little pricey at $20, but that's the best deal I could find for it. I'd rather pay a little more than get one that will crap out on me in a month. And it terms of a slower charge (500ma) being more beneficial for a longer battery lifespan, I'd rather dish out $10-$15 in 6 months or so for a new battery than to have to deal with this ridiculously slow charging time
Another option for 1A (1000mA)...
Not to resurrect a dead thread, but I think this may be useful to know:
Several other EVO forums ("fora?") have reported great success with this low-profile charger. I just got it off of amazon myself...

You can also get 1-meter cables from Blackberry themselves on Amazon for $2.50 each, so if you have Amazon Prime, gets you a flexible solution for 11 bucks or so. I have ordered mine and will report back in 2 days...

This is actually the same one I linked earlier minus the iPod cable and much cheaper
EDIT: Best Buy seems to have stopped carrying this product. I updated the link in my post above to Slappy_G's post

Do they make one with 2 USB ports? One for charging the phone and another for your Bluetooth head piece.

I'm not allowed to post links yet, but you can search for Scosche to find their products. They make dual port USB chargers.
Scosche makes a couple different models, one is advertised as having 2 amps over the two ports.
On a side note, I tried buying a blackberry micro usb cable off Amazon, and it starts to charge my phone for a second or two and then stops, it's very strange. I think it might work with the home charger, but I didn't check as I didn't notice till later that the charging stopped so soon.
Doing some cleanup and checking threads I promised to respond to...
The Belkin works great, and my wife has the 2-port Scosche. However, for me, NEITHER of them show "Charging(AC)" on either of our 2 Evo's. I have tried the charger in several cars, and same result. Not sure, but I'm guessing they are putting out incrementally less than 1A.
Not sure if that keeps the phone from triggering "quick charge" mode or not.
I just got 2 HTC car chargers from ebay, sent from Hong Kong. It says o/p:5.0V-2A so im not sure if I should use them.. here is what they look like.. http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&item=170511321504&ssPageName=STRK:MEWNX:IT
Does anyone have a OEM car charger? I would like to know how many amps it puts out. The wall charger is 1A so will 2A kill it? I sure wouldent use it much only if needed.
I have a charger from iGo, works great and has swappable tips so you can use it with other phones or devices, think it was $15-20 with a free tip.

Can someone here confirm that this does deliver the full 1A? There is a review on Amazon from an EVO owner who says his phone sees this as USB and not AC charging.

If you were trying to draw three amps from a 2-amp capacity charger, you could damage the charger. However, a device that draws 1 amp from a 2-amp charger will draw one amp. Chargers don't push more amperage than is demanded: it's up to what the charging device is drawing. You and your device will be fine in having "too much" charger.
Thanks so much for the info. So this charger should work great then when I start using the sprint nav or google maps.

Just received two in the mail.
FAIL
Recognized as USB charging in my car.
plus 1 for resurrecting a dead thread
I bought an off brand one (looks about identical) in a respectable local supermarket. It claimed 1.5A.. so overspecced (and no there's nothing wrong with overspeccing, devices won't draw more power than they can handle so long as the input voltage is correct).
Like the previous poster's belkin experience, my korean SGS (shw-m110s) saw it as a usb, not ac. I took it apart and shorted the data pins together, took about 5 minutes). Then it recognized as AC and charged a little faster I think, but still at empty (the fastest time to charge normally) it charges about 1% (1.5 mAh) in 2 minutes(.033 hours).. which is just under 500mA charge rate (450 but well within the measurement error and 10% loss seems quite reasonable anyway). Anyway, sure as heck isn't able to draw 1A off of it. The wall charger which is supposedly only 700 mA charges several times faster actually! (which is probably quite safe at low charge levels, but sure seems like alot more than 700mA too me, but I didn't measure it as well).
I suspect this gizmo was never actually meant to output 1.5A (as it's not configured as a quick charger) or if it does, it only does it with large losses, and an internal voltage drop that's too excessive for the SGS to still be capable of actually pulling that much current.
Wish I knew what to buy.
I Have been using the official palm charger since June. I picked it up at sprint corporate store or radio shack. It is rated for 1 amp and come with a nice short micro usb.
If I were buying today I would go with one of the Platinum branded items Best Buys sells. I saw them for the first time last night so they must be new. So far I have purchased the Pt branded case for EVO and 2 different mounting kits. All of their stuff seems top quality. The have a 2 amp single usb and a 3 amp dual usb model that I saw.

Does anyone know - is a 1 amp (1000ma) car charger the recommendation on the mt4g? Where's the best/cheapest place to buy one? It seems like most of the time, amps are specified in product details.
Also, I assume if you charge off of your laptop usb port, that it'll be charging at 1 amp as well?

Belkin makes a micro usb charger that's 5v 1a. I think I paid 20 bucks for mine. It works well and is TINY. You can use it to charge anything that uses a usb cable.
http://www.belkin.com/IWCatProductPage.process?Product_Id=489423
IGo Makes a great line of chargers. I have their car and home chargers. They work great and if you get a different phone all you have to do is get a new tip. This way you don't have to contantly buy new chargers.
How about $1? Yes, $1.16...

if your looking for cheap just hit ebay... you can get the generic's for like a buck with free shipping
i wont touch car chargers with a 10 foot stick... the electirical whine from the alternator distroys Li-Ion batteries...
i use usb to computer or to one of those "emergency battery chargers" just another Li-Ion batt, if you plug the emergency charger into the car, and the phone into the emergency charger the battery in the emergency charger will take the hit....

This is a new one for me. Can you back that statement up with proof? (not being rude - just curious)
FYI: A good all-purpose micro usb charger is the Motorola P513 ~$10.00 with S&H on Amazon
Sent from my HTC Glacier using XDA App
i can poke around on the interwebs... but mostly thats from years of experience with phones, years selling phones, and chargers (RadioShack).
you can prevent all damage by charging the phone while the car (alternator) off, or by using a power inverter, or with the extra LIon batt solution i mentioned above...
NEVER plug the phone (directly) into the car, and then crank the motor, the (electrical) whine is at its worst as the alternator comes up to speed...
at the same time, this is what i tell all my customers:
"cell phones are convenience items, if its not convenient to do, then dont do it"
most people will find the tradeoff of having the phone charged "now" vs diminished batt capacity an easy choice to make... but not all people are like "us"
it surprises me that HTC endorses the use of car chargers with car docks...
but those 1$ chargers on ebay are the worst, most are non-regulated, and could dump 12V into the phone at the smallest problem. 12V will absolutely torch your phone...
you will do what you like... just food for thought
Hi All! So this is my first time starting a new thread so I hope I'm doing this right. I couldn't really find a thread specifically for battery banks or battery backups so I thought I'd start one.
I was wondering what is everyone's method of backing up/recharging your battery for your cellphones? For me, the battery that comes with my phone is enough to get me through the day usually and I just charge it every night while I sleep. If I go on trips, I use the Rav Power 10000 mah battery bank. I find this a bit bulky but it works great and lasts many charges before I have to recharge again.
Everyone's taste and preferences are different so I'm seeing what other options are out there that may be lighter in weight. I'm thinking of getting their smaller one, the 5200 mah, and have this in my backpack or car for just in case.
Any mini reviews of what you have would be great :good:
Wow, cool gadgets, I need to get a bank for just-in-case emergencies. Thanks Currently i use a solar powered charger, which is really slow and somethings doesn't work as desired. Looks similar to this http://www.amazon.com/External-Univ...=8-4&keywords=solar+powered+cellphone+charger
Ive bought one at sunsky from china battery about 4000mah, but it was year before, now there is a better.
I used to have a bank that looked like a GBA SP, with foldable screens. In the screens were two solar panels, which charged the battery of, I think, about 2000mAh or something like that. The thing is now broken though. Still looking for a nice (affordable) replacement
Mine is Anker 5600
I use the Belkin 4000, size similar to a ext HDD and look nice, pocketable too

Charger considerations
Hi,
I need advise for the following:
Charger A (Li-polymer battery) output : 5V, 1A
Charger B (Li-polymer battery) output : 5V, 500mA
Device input: 5V, 750mAH (Li-ion / Li-polymer)
When using Charger A, some people comment that it will limit the current of 750mAH for the device and the device's battery should be fine since both the charger and device are at 5V. However, some people comment that this will shorten the battery life of the device since it will perform a 'quick charge' using 1A.
When using Charger B, some people comment that the device will draw more current than it can deliver and causes it to heat up and reduces the charger's life. However, some people comment that Charger B will extend the battery life of the device since it performs a 'slow charge'.
I also read that USB pins on the charger denotes if the charger is a PC or a dedicated charger. If it is a PC, the device will limit the drawing current. If it is a dedicated charger, the device will draw more current to charge itself.
I am confused as to who is right and which charger should i be using.
Can someone enlighten me ?
Thank you very much.
bought this one from Ebay, has not yet arrived, therefore I cannot tell if its good or not.
but for its price its quite a good bet, 12000mAh for 33 bucks (on sale until tomorrow)

Hi, I use choiix power fort 10Wh http://www.coolermaster-usa.com/product.php?product_id=3001 it have 2700mAh and it's small and looks very nice. It can give one full charge for my SGSIII
I went on a trip this year and searched for a good bank, and this showed up.
http://www.sayes.co/20-powerbank.html
I tried it and it was really good, it has lots of adapters and it's cheap =P
I was able to order a RavPower 5600mAh on sale a while back ago, that was posted on slickdeals. here. I am pretty happy with the performance of the little backup, it defiantly gets the job done. My only complaint is that the body gets scratched up easily.
I was comparing the Ravpower and the Anker 5600 and they both look exactly the same except that both are branded with their logos. So I'm wondering if they're from the same manufacturer. Going to have to do some more research. However my current Ravpower power bank I do have is working great and I love this thing for trips.
I'm also thinking of getting a solar one for my 3day emergency/bug out bag. Thanks for all the suggestions.

Yeah, can someone please let me know if they are the exact same manufactuers, except for the company logos on them? I am deciding between the two. Also, what do you guys think of their 2600maH stick version? Which manufactuer would you go for over the other and why? I am very interested.
I'm using a "Scosche SolBAT II Solar Powered Backup Battery and Charger" which I bought off Amazon for something ridiculous like $15 last year.
I bought it for hiking mostly as an emergency charger. I use a Huawei phone as a GPS out in the wilderness, and the GPS app (Androzic) is quite power intensive. I have also used the same device on an iPhone and an iPod touch. The Huawei phone will receive a full charge from this battery, but the iDevices will only go to around 75%.
The solar cell on the back of the battery isn't all that efficient and will take about two days to charge the internal battery, but having it there gives you more options should an emergency occur while in the wilderness. A half hour charging in full sunlight would provide enough power for a short call or a couple of texts to family or emergency services.
The device comes with suction cups and a small carabiner, so it can be stuck to the inside of your car window or clipped to the back of your rucksack. The device is lighter and smaller than the average smartphone and can be fully charged by USB in about three hours. Interestingly, the device has a LOT of bad reviews on Amazon, so maybe they simply sent me a good one.
I also have a very cheap and nasty handcrank USB charger from dealextreme which can be used to add a bit of juice to the solar battery pack at night or in cloudy weather or can directly charge the phone in an emergency. It's a little flimsy and takes a fair bit of cranking to get enough juice for even one call, but it weighs nothing, cost about $2 and is cheap insurance out in the boonies.
My list of power equipment for the phone/GPS and the iPod Touch for a multi-day walk are as follows:
Short Micro USB cable x 1
iPod USB cable x 1
Scosche SolBAT II battery/charger with alloy carabiner
DX hand crank battery charger
Total weight is less than 200 grams

Honestly i went with pricing. I assume if they look the same they are from the same vendors/manufactures but different brand/company. Reviews for both sound very good too. Ravpower had a promo going on a while back and i tend to see them pop up from time to time on slick deals. The stick might give you one charge but since it looks smaller than the rest, it may be the easiest and lightest to carry around. I say get a decent sized one. Anywhere between 5600mah to 10000mah so you can go through a few charges without needing to charge again.
I have a 6600 mAh(well, in my experience it's not true, more like 4-4.5k), but I rarely use it after I bought a tablet with a fullsized usb port in it.

I was looking for a solar charger. I bougth one but it crashed in two days. Therefore I returned it and now I am waiting for another one. In the place I live there are few options
I just lost my USB wall charger and realized my spares don't charge as fast as my previous one...
My previous charger had my phone at +700ma while in sleep, two of my spares can do 400 and one can only do 200!
One time I used a car charger that had me at +900ma in sleep so I would like to try and find a new wall charger that can get me +900.
BTW all the chargers I have used have said they are 5v 1000ma, so clearly I can't just go by the specs they list- I need a first hand experience of a quality charger.
So I open it to the forums. Anyone here have experience of a particularly strong USB wall charger?
I got a good Motorola one on Amazon for pretty cheap and it's been going strong for a while.
Sent from my GT-N7100 using xda app-developers app
Well, you do need one that's 1000mAh.
You just need one from a reliable manufacturer that's not mis-labelled crap.
I'd just look for a quality brand. I got lucky with one for $1.50 on eBay but the seller isn't selling them any more.
Hm so I guess OEM or genuine name brands should reliably be up to their specs, then? Well, I guess I'm going to shop around for one that maybe says 1500ma or more because I believe my phone can take more than a 1A charger can give it, and it probably won't disappoint
Samsung note II have a battery of 3,100mAh, the charger is 2000mA(2A). but my i can use the same charger for my S2. so i guess that the amphere doesn't really matter. just that the higher the amphere of the charger, the faster it charge. But you sure need a higher amphere charger for bigger battery. Hope this help.

I've read that smartphones (at least android phones) have controlled charging circuits that will only allow for as much amperage as they are set to allow. So if you connect a 2000mA charger to the phone but it's limited to 1000mA then it will only draw 1000mA. However as I have noticed just because a charger says it can output 1000mA doesn't mean that it can. I have tried 4 different 1000mA chargers each with pretty different outputs- and if they don't output as much as your phone will take it WILL charge slower. The point of this thread was to gather information on which chargers are reliably fast and ideally economical ones (there's enough OEM chargers I can find for 10x the price of off-brand ones that would hopefully do the job right).
The retail charger that comes with the Moto X charges the phone three to four times faster than after market or other phone's chargers. Two questions:
Why is this?
What technical information about the phone/charger do I need to buy replacement chargers that have the same fast charge capacity?
Thanks!
Taken from Anand's review:
"The Moto X comes with a dual-USB port 850 mA charger, like the previous revision of Motorola devices. In practice I've seen the Moto X reliably pull closer to 1 A from the Moto X bundled charger.
What's interesting however is that the Moto X can charge up to the maximum BC1.2 rate of 1.5A. If you use that kind of charger, it charges impressively fast, around 2.3 hours. "
So when I look for chargers I want one that can provide up to 1.5A? Are there any other caveats needed to make it draw that much? I have a feeling my other chargers theoretically can pull that much but don't for compatibility reasons?
Nope. Just look for one that outputs at least 1.5 amps. More amps will not hurt the phone as the phone will only 'request' the amperage or can handle. Ipad certified chargers are typically rated for 2 amps or greater. Be aware though that if it's a dual USB charger and you plug something into the second plug, you most likely won't be getting the full amperage on both.

Thanks a lot! On a similar note, I have a usb car charger that plugs into the cigarette lighter receptacle. Do I also want to find I one with 1.5A+ output?
Charging faster isn't necessarily always a good thing - remember that a byproduct of quicker charging is more heat - and in the car, especially if you're running Gmaps, etc you can hit the thermal limits so it'll actually stop charging until the battery cools.
I figure there's gotta be a reason besides price that Moto didn't ship a charger without 1.5a support.
I have the "andru" charger that is like $25 on amazon and its one or the fast type chargers. Probably not the cheapest but its a cool looking charger. Lots of friends have them too and love them since Google gave them out at Google I/o
Sent from my XT1053 using Tapatalk
If you can afford the time, I'd recomend a slower charger. Slower charger means less heat which is better for the (non-replaceable) battery.
Hy everybody, I think this is the first time I'm posting in the forum. I don't know if this is too old for a thread, but I've lost my charger (feel really bad about it) and I'm now charging with an universal 0.7A charger. However I'd like to find a Motorola branded charger again, id anyone knows a place where I could buy in Europe? I've checked ebay and couldn't find one that I can be sure it's coming form Motorola. If I cannot find one like that, I guess it'll be ok to buy a 1A charger also universal, based on the discussions here?
