battery charging question - HTC EVO 3D

I have a portable battery pack which can be used to recharge tablets & mobile phones whilst out & about. Its output is rated at 5.1V 2000mA. I think the stock mains charger that comes with the Evo 3D is 5.1V 600mA. Would it be safe to use this battery pack to recharge the Evo?
Thanks

The stock charger I have for a cdma EVO 3D is 5V and 1000ma, which is standard for all HTC phones. I've used my dads charger which is rated 5V 1800ma output and had no problems. But I only kept it connected for about 30 minutes.

You'll be fine, that's probably more of the battery packs capacity and not output.
But no matter how many amps a charger can supply, the EVO is what controls the draw, and our phones will only draw a max of 1amp or 1000ma

I seen a post just like this on ppcgeeks....
I would stick with the stock charger just to be safe If you try another one out just keep a eye on it while it is charging to make sure nothing gets hot or a fire starts.

Like Chuki82 said it doesn't matter what the output is because thats only the maximum output. The Evo 3D will take what it needs, so nothing bad will happen.

The only complaint I've heard is when the charger is too WEAK for the phone. Then the phone sometimes gets very hot like it is overcharging, but does not charge. As others have posted, too many mA is OK.

Thanks everyone

Car Charging?

So I went on a 2 hour trip using my EVO as a gps. I had it plugged into the car charger the entire time. Little did I know the EVO was using the battery faster than it was charging. I've done this many times with the EVO 4G with no problems. Any suggestions? The phone is basically useless as a gps for any long distance trips. The battery will never last.

get current widget, it tell you how fast your phone is charging, and when unplug how fast your phone is draining in mah, note your mah usage when unplug, then note your mah usage when battery is fairly low and plugged in to charge with the car charger.
if your battery is low (below 50%) and your phone still won't charge faster than 500mah on the car charger, it will not keep up with GPS uses, be aware that as the battery approach full, it charges slower and slower, near 97~99% it will only charge @ about 100mah rate.
I bet you have a cheapy car charger that only supply 500 mAmp, get one that can supply 1000 to 2000 mAmp (1A to 2A... 2A usually for DUAL usb outlet type charger)
deleted... double post hmmm
Mine wasn't charging unless it was plugged into the wall until I typed ##3828# and checked "enable USB charging". Now it charges while plugged into a computer or car as well.

I've never had a problem using this older but more powerful iGo AutoPower 3000 car charger. Overstock has them for $6.50+shipping and you get a bunch of power tips with it but not a microUSB tip.
http://www.overstock.com/Electronics/iGo-AutoPower-3000-Car-Charger-Power-Adapter/3668307/product.html
The power specs on the package I have say:
DC Input: 11.5-16 VDC
Power Output: Up to 15 Watts continuous
Radio Shack sells the iGo a97 tip for $10+taxes but Amazon has the tip for $6+shipping(free shipping if you have prime).
http://www.amazon.com/iGo-Kindle-Motorola-RAZR2-KRAZR2/dp/B0012J52OC/ref=sr_1_1?ie=UTF8&qid=1310316568&sr=8-1
From my understanding, the tips have a resister in them which limits the mAmp output but I'm not sure what the a97 tip specs are since iGo doesn't seem to release that info. Hopefully it's 1A like the wall charger. I can verify that the newer single output iGo chargers are limited to .75A. So even if the tip is 1A, the charger is the limiting factor, hence why I recommend the older, more powerful one.

Read the label on the charger, make sure it say at least 1A or even better 2A
lots of cheapy dual USB on ebay that's not rated for 2A
if you got a 2A charger and current widget still show 500ma charge rate,
then you may have to figure out if your phone is charging in USB charge mode with the car charge (limit to 500ma by the phone per USB spec) or in AC charge mode (charge at up to 1A)
I just came across this other day that point out this problem.
http://www.amazon.com/gp/customer-m...B9U8Q/ref=cm_ciu_pdp_images_3?ie=UTF8&index=3
look at the mouse over box comment... of course every charger is different so don't just blindly do the mod if you have a different charger.
as for the other guy asking for 2A charger....
Ebay and Amazon have alot, just make sure they specificly say 1A for single USB or 2A for dual USB output.
for 2A dual USB, the OEM HTC thunderbolt one seem to be the best but also most pricey, some alternative are the Motorola dual usb and the Tmobile my touch 4g dual USB

Was having the same issue;
I used the car charger I had for my EVO, left it on for 3+ hrs, with little to no increase from where I put it on at. Ended up using a buddy of mine sharger and viola. Imex99 explained the reason for it. Just buy a new charger with 1A/2A output rating and you'll be good.
I'm having the same issues. I click enable usb charging and then commit, but it keeps reverting back to disabled with no difference in charging capability.
Speaking of car charging, why does the battery temperature vary so much between AC & USB, versus Car charging?
With the supplied HTC AC charger or USB connected to a computer, the battery's charging voltage is 4.333 volts and the temperature is 81*F.
With a Sprint Car Charger, the charging voltage is 4.333 volts but the temperature is 95.5*F
Even chargers rated at 1A/2A may not have the appropriate pins soldered together to enable 1amp charging. Please see this thread I made when I had the Evo 4G:

[Q] 2A Charger for Evo 3D

Hi,
I was wondering if it will be OK to use a 2A & 5V with Evo 3D. Evo 3D dies after a while when it's connected to HDMI Dock. Their is not enough current to keep it alive. And with a 2A 5V charger will also charge my Samsung Galaxy Tab 10.1.
Thanks.

If I remember my physics correctly, you should be OK because the phone will only use the amperage that it needs.

I a little worried about it might heat and might adversely affect the life of phone. As long as it's not too bad, I am fine with it. I plan to leave my phone on dock, so, I will be connected to 2A charger with extended period of time but then their should be some safe guard implemented by HTC to handle such scenarios.

I've actually heard from friends that their phones got hot when they did not provide enough amps. Using a 500mA charger for the 3d got their phone piping hot for some reason.

I am not sure I understand you. You mean to say even an extra 500mA, that is 1.5A total, would get phone hot. HTC 3D requires at least 1A of current, so, it won't charge with a 500mA charger.

Not true. The phone will charge with any amperage. I have an old car charger that only puts out 200mA, and it charges just fine. Obviously it doesn't charge very fast, but it's enough to keep the phone topped off when I need it.

No, and as stated above, it will not hurt the phone either. The Evo will draw at max around 1 amp. You can use a 2 amp charger, but the phone will not charge any faster, as it will only draw 1 amp. I use my tablet charger once in a while, which is also 2 amps, and can confirm the phone is only drawing a little over 1 amp from it.
When I connect phone with TV through HDMI dock. Phone draws more power than 1A charger supplies. Will 2A charger be able to provide that extra charge, so, phone wouldn't die or depleted of power?
I don't mind heating as long as it's not frying phone chip anytime soon.

If the charger is rated higher than one amp you should be alright, but I wouldn't recommend using one rated lower than 1 amp (or 500mA for usb/car chargers)
I just fried a charger not too long ago because I plugged my touchpad into it and it was only rated at half what that draws.

Battery Charge / Discharge Info

OK. Here's the deal. I have several chargers, AC and 12 volt. I was trying to see if one charges faster than the other. I have used currentwidget forever to see what the charge/drain is on my phone. But here's the question... I have read that the Evo 3D limits incoming current to 1 Amp (1000 mA).
1. Is this true that it limits the incoming current?
2. Is there an app or other way to test what current is coming into the device before the 3D limits it back to 1 amp?
3. I have 2 amp charges, both 12 v and AC. and while screen is on, currentwidget and battery monitor only show about 250-300 mA charge. Shouldn't it be higher? When not charging, drain is only at 500-ish... So I would assume charge should be 1000 mA minus the drain??? So it should be charging at roughly 450-500 mA.
What am I missing?
Edit: One more question... Wat is the max charge rate for AC charge vs. USB charge?
If you continue to raise the amperage, you might get a beautiful camp fire.
Stop playing with AC/DC and then complain that HTC builds bad phones that don't resist in time.
Is that hard?
The phone should only draw what it needs. I think that is the 1A, whether there is draw or not. Minus what you use gives the extra mA.
As for Usb vs Ac, Usb is 500mA, AC is usually 10A from the wall (I believe).

Your using a third party app not precise equipment there was all sorts of talk when the 3d was released about power transfer rates being unsafe it turned out the third party apps are just ALWAYS wrong when it comes to this. There is an old article on good and EVO about it.
Edit: for what its worth I noticed a faster charge on my touch pads 2 amp charger. But it could have been placebo.

I agree with the math, but it just seems low to me. And AC varies from charger to charger. HTC wall charger is 5 v DC at 1 amp.

I use my 2 amp TouchPad charger for my 3vo too. And it does seem to charge faster, but I think it is just placebo. Battery apps and current widget say only about 400 mA is used for charging. I would have assumed 1400 mA if it were not being limited to 1 amp into the Evo...

For starters, I am not sure if the Evo limits the incoming cirrent, but the stock chargers are only 1 amp output. Regardless of that, look at the wire diameter in the typical usb cord. While it may not sound like much, to get to 2 amps, would mean pushing (if my memory serves on the power formula) 10 watts of power down the cable instead of 5 watts. I am not sure the resistance of the wire wouldn't go up due to heating and effectively cut your power into the device anyway. I am not talking enough heat that you could feel it, just enough to slightly increase the wire resistance resulting in a power loss.
Like someone else stated, the USB ports are spec'd out to deliver max 1/2 amp
For question #2, regardless of what a source charger is capable of putting out, the device will "draw" want it requires upto the source maximum. Therefore if the device is requesting 1 amp, then that is what is coming out of the charger. If you were able to put an ammeter in the line, you should find that as the battery got to full charge, the current in the line would drop to the value necessary to operate the device and no more.
More information than you likely wanted,

A lot of chargers will be rated less than the stock charger. Especially cheap car chargers. In that case the phone can only draw at the charger rating.

The values listed on the charger is the max output it can provide. If the setting on the phone or the hardware is set up to only pull 1A, then it will always pull that unless that is more than what the charger can provide.
That being said, you should be able to take the battery out and charge it faster separate from the phone. I've always read, though, that charging a battery faster ( i.e. turning up the current) will/may reduce the life of the battery

I have a Touchpad charger and it can be used, though I noticed that the phone got hotter than normal, IMO. The phone comes with a 1.0A combo wall charger with USB cable. Interestingly the Samsung stand and battery charger that comes with the spare battery comes with a .7A charger but the charging unit itself is 500mA/1A on the input with output at only 4.2v @ 450/900mA.

No rapid charge using non-HTC chargers?

Hi all,
When I use the charger that came with the HTC One my phone charges great, rapid.
But when I use any other charger that I have in my home/office it charges very slow. Even with a 2.1 amp charger!
The charger that comes with the phone has an output of 1 amp.
I've tried multiple other chargers (1 amp and 2.1 amp) and they all trickle charge.
Anyone else noticing this?
Thanks
Joe
I'm using old charges at home and in the office and it did seems slow but had not heard of rapid charge. Will the phone indicate this rapid charge mode? If not, is it real?
I'm getting slow charging even on the stock HTC charger. Not sure how I can enable this rapid charge cause 4+ hours from 0-1% to full is a bit ridiculous.
use orginal charger is best , maybe it has some relationship with your battery life
If anyone is coming from phones with smaller batteries, remember the larger the capacity the long it takes to charge.
I use the cable and charger from my Nexus 7 and it charges fast. Off my USB it is slow.
Real AC chargers have two pins shorted. You can hack a USB to micro USB cable and short the same two pins to enable AC charging with any adapter, wall, USB, or car. Should be pins 3+4, but don't hold me to that.

i've done exactly this, and damned if the One still refuses to draw more than ~500 ma off of anything but the 2.1 A wallwart it came with (i don't have any others to try with). i'm about to dig out an old inverter to see if that will actually work. wish i'd paid more attention to my EE dad when i lived at home; i've gotten a serious crash course in this stuff while trying to get my One to charge in my car, when it's on.
edit: so i got my old inverter out, and spent about 15 minutes testing. i used the 2.0A adapter that came with my Nexus 7 to test, as well as the 3.1A Mediabridge adapter i got here. my phone was at about 45% when i started testing. unplugged, Battery Monitor Widget reported a drain of anywhere between 500ma and 650ma (running Ingress, wifi on). plugged in to the Mediabridge adapter showed, at best, a drain of 50ma. the Nexus adapter plugged in to my inverter charged at a fairly consistent ~120ma. i didn't touch my phone the entire time.
i left my Nexus 7 at work so i can't use it to repeat the test, but i will do so tomorrow. the cable i'm using is this one. i'm not crazy about having a ridiculous DC-AC inverter in my car for my phone, but if that's what i have to do so it can be used and not drain, then so be it. admittedly, i don't really understand these things enough to explain these variations, but i plan on learning ASAP. perhaps somebody else can shed some light on why the device charges different, and how it identifies an AC-USB adapter vs a DC-USB adapter.

Math doesn't support what is happening though. Phone has a 2300mAh battery. The OEM charger outputs 1A (1000mAh)
At most, it should be around 3 hours for full charge, when in fact it is closer to 4-4.5 hours. It's the last 10% that is the issue, it will trickle charge to 100% rather than rapid charge.

I read a pretty good article recently about Li-Ion batteries that talks about how trickle charging is the best for battery life, and it wouldn't surprise me if HTC got a little aggressive the way the this phone charges since we can't swap the battery ourselves.
I'm trying one last car charger, which matches the wattage of my Nexus 7's 5Vdc/2A AC adapter (which I've had the best luck with, when charging the phone while in use): http://www.amazon.com/gp/product/B009TBF7IG/ref=oh_details_o00_s00_i00?ie=UTF8&psc=1
If that doesn't work, I'm going to put a 300W inverter in my car with the AC adapters themselves and stop buying stinking DC adapters. This phone clearly pays very close attention to the wattage available from whatever it's plugged in to.

I use the cable and charger from my Nexus 7 and it charges fast. Off my USB it is slow.

Same here, 2a Nexus 7 brick with a long Logitech USB cable, much faster than stock (and longer)

I'm fortunate my car has a built in inverter that I use for charging my phone.

My next car will too, because I can only imagine that power requirements for these devices is going to increase.
That said, I think I have a winner, and instead of retyping my posts, I'll just link to that thread instead: http://forum.xda-developers.com/showpost.php?p=41797839&postcount=6
Since the snap Dragon 600 has fast charging capabilities, why didn't HTC Include it in the kernel??? I've noticed my 2500 mAh note battery charges faster than my 2300 MAH HTC one
