Will this work for car charger?

Looking at grabbing a couple extra car chargers and came across this:
http://www.monoprice.com/products/p...=1083301&p_id=6152&seq=1&format=2#description
There were a couple of reviews stating it works on the EVO, but I'm concerned about it being 1100mAh vs. 1000.

You'll be fine. Devices using power draw amps, chargers don't push them. Your car's alternator is probably around 70 amps output, yet the fuse on your radio is commonly 10 amps or less.

Its not rated at 1100 mAh its rated at 600 mAh.

What is the guide line for buying a car charger for the evo when you plan to primarily use gps via Google navigation?
I skipped the cheap eBay chargers thinking it'd be a waste, yet here I am on my third charger from different manufactures trying to find one that will chArge while using the gps.
What is everyone else doing? Are we just supposed to not expect these evo to not charge while using gps?
Also, today I drove about 35 minutes while using gps and using one of my new charges and it didn't charge the battery at all. Also I noticed that when I reached my destination that my evo wasn't charging at all, intact the charge led on the phone was off...and my phone seemed hot.
Sorry to hi jack but my question seems relavant.

I have had good luck with a Palm car charger I picked up at Radio Shack on clearance. It actually puts out enough to keep up with constant navigation use. I have actually had Google navigation running, while streaming Pandora to my stereo, and my Evo was not discharging, display was at 25%. It got pretty warm, but didn't lose any power, it didn't gain much either.

Real chargers start at 99¢ on eBay.

Circuitry in the batteries themselves limit how much amperage they'll allow in: more charger will not increase the power, nor shorten the charge time. It's a circumstance of using lithium as a power cell.

So your saying that a 300mah charger will charge our evos as fast as a 1 amp charger?

I recommend getting one of them htc charger that has the blue led htc letter on the back. Or get the sprint one that is very long. You can find them both on ebay for under $10. I have the htc one which charges quickly but fit too loose in the cigarette lighter and sometime loose contact. You can also try using a power converter and charge your phone using the oem home charger.
Unfortunately our evo does become hot when using gps for extended periods. I solved it buying a soundgate m2 mount and putting it near the car's a/c vent. Shouldn't be a problem when the weather gets cooler.

Fascinate wall charger WILL charge the GT 10.1

Interesting to me, though maybe already known:
I could not find my GT10.1 wall charger the other day, so on a whim I tried my Fascinate's wall charger (with GT 10.1 cable). This wall charger seemed to charge the GT 10.1 with no issue.

$0.43 + $3.48 shipping on Amazon - pretty cheap way to get a back-up to stick in my backpack.

As should any USB type charger. My iPhone charger and my Jawbone Icon headset charger worked as well but takes longer to charge due to the lower current rating.

Agree with MisterEdF.
I have the same plug with my Nexus S and my Epic. Both WILL charge but it's slow as hell and there's definitely the Red X letting me know that it's not the 5v2a charger the tab would like to see. Can't see why the Fascinate charger would be any different...

I believe that is a .5a charger and our tabs come with a 2a. The most it really can do is slow the battery drain. It'll take at least 4x the amount of time to charge.

I dunno. Over a ~couple hour period the battery went from 24% to ~50%. Not as fast as the stock charger, but certainly not zero.

It will slow the drain if you are using it but if you simply want to charge it over night it should be fine in a pinch.

And so will the B&N Nook Color charger. Essentially, any one will work but the standard, lower capacity ones might take forever to charge. The Nook Color charger provides ~1.9A @ 5 Vdc in place of the more standard sub-1 Amp chargers.

For those with charging issues [Possible Solution]

There have been quite a few people that have come into one of the IRC channels for this phone with complaints of very slow charging batteries. There have been a lot of theories regarding the slow charging, but after testing for about a week I think I may have a possible solution.
Many stated that they were using USB ports on their computers or USB hubs, while others stated that they were using the wall adapter's from their old phones. The problem with this is that, although USB 2.0 ports have 5v output (the same as a wall outlet), they only MAX out at 500mA (milliamps) or .5amps. USB 3.0 ports output at 900mA, so this is almost twice as much as 2.0...but still more than half as low as the wall charger. Also, not all wall adapters will handle the same electrical output. They range anywhere from .5amp through 2amps. The one that Samsung bundles with this phone is 2amps.
So, if you are experiencing extremely slow charging while connected via USB to your computer or hub (or even using the wall adapter for your old phone) then you may want to charge your phone via the supplied wall adapter. I realize that its probably inconvenient as most like to connect their phone to their computer while they are at it, but you can't have it both ways. And for anyone that thinks that their USB 2.0 ports are somehow magical and their phone charges more quickly than others through this method, it's not possible as 500mA MAX is the industry standard.
I tested my, and my girlfriend's, phones for the last week, and this is indeed very much the case. Laptops can put out slightly more amperage, but it is negligible.
Charging tests were performed on 2 different laptops and 2 different desktops (one through a hub and one direct to the USB port on the PC itself).
Charging from dead via USB took ~8 hours (one actually took about 12 hours during one of the laptop tests) to fully charge from dead.
Charging from dead with the supplied wall adapter on either phone took ~2-3 hours.
Charging from dead using the wall adapter from the HTC Evo 4G took each phone ~6 hours.
I realize that this will vary in some degrees from user to user, but I think for the most part it will be correct. I also had two friends run similar tests (one used the Evo 4G charger and one used the Evo 3D charger) and their results were very similar.
Most of this is probably common knowledge to many people, but for those that didn't know, I hope this helps.

Umm...the charger included is rated at 1A?

i have no charging issues, what i have found is that the charging light wont go on after low battery warning unless i power off phone and then reboot.
and to stay on topic..
2-3 hours a/c charger
4-6 hours usb or d/c
light use gets me 2 days on battery - stock / no root

Car charger that's recognised as an AC charger

Has anybody already found a charger for in the car, which is recognised by the phone as an AC charger? (besides from the official HTC car dock/charger)
Because the charger I'm using is recognised as an USB charger, and therefore doesn't charge faster then 500mA.

All the chargers I have are recognised as notmal charger, never had this problem you mentioned.

No problems with my car charger either

What chargers are you using?
And it's not a big problem, it's not even a problem, it's just how the charger/phone works..

having it recognize that it is AC vs USB is one problem... but even if it says it is charging via AC, it doesn't always pull more than 500ma (even if it is a 2.1a charger, etc). i've been testing chargers and inverters w/ac adapters all week. i've got one more to test before i narrow down the issue (hopefully).

this was just delivered: http://www.amazon.com/gp/product/B009TBF7IG/ref=oh_details_o00_s00_i00?ie=UTF8&psc=1
tested it using my normal method-- watching Battery Monitor Widget for about 20 minutes, while running Ingress. the app reported battery draw fluxuated between -56 and +300. i've been using Ingress as my test app because it tends to really hammer my battery. this new charger doesn't seem to be as consistent as the 5Vdc/2A wall charger i use with an inverter, but i'm going to keep trying it to see how it works in 'real world' cases over about an hour or two. i'll let you know, but this charger is potentially an answer to this car charger issue.

Ok that looks promising indeed. Does the phone recognise it as an ac charger?
Too bad I can't order from amazon.com and on amazon.co.uk it's not offered.

Yes, it is recognized as AC-- but so are most of the car adapters I've tried (mostly, those just have the 2 middle pins on the USB port shorted), but they have a lower wattage output, typically at like 6-8W. I bought this one specifically because it says it can output 5Vdc/2A, or 10W, per USB port. I suspect it will dip below 10W when both ports try to output at max capacity, but I'll be able to test that this weekend (and aside from testing, there's virtually no time where I'd have a need of that).
I performed a second test, about 30 minutes of talking on my phone via a bluetooth headset, Ingress open and running, push emails for GMail and Exchange, full brightness and volume, etc, and it only dropped down to discharging a handful of times. This is definitely much closer to the results I've gotten when testing a 5Vdc/2A output DC adapter.
You might be able to find other 5Vdc/2A adapters on Amazon UK, and ruling out the 'piece of junk' factor, hopefully some of them will work. I'd think that for the duds, you can at least return them for a refund by stating they don't output the proper wattage as stated on their product pages.

IMPRESSIONS
This charger blew the socks off my OEM charger. I got it when I had my HTC One M7 and the charger that came with that phone did an okay job - but it was more like a trickle charge. When using this charger, I was able to get a full charge from an almost drained battery in about 2 hours. And it was roughly the same time to charge both my wife's Samsung S4 and my M7 at the same time. :highfive:
This charger is great. It has two ports and it is has good build quality. I have been using it now for a few months and it is still going strong and charges my Nexus 6 great when I don't want to use the insanely fast turbo charger.
Not quite sure what the "Smart" port is for - the box did not come with a description on that.
RECOMMENDED
I would recommend anyone in search of a USB wall charger to purchase this product. I have used OEM chargers, and cheap replacement ones, and this one beats all the ones I've owned, hands down.

Will this work with a Kindle?

"Smart" USB chargers include solid state logic with serial communications chips. When you plug in a device that wants higher current, it sends a query to the power supply saying something to the effect of "I want 2 amps. Is that OK?" If the power supply is a dump USB port, it doesn't answer at all, so the device either doesn't work, or only draws the default 500 mA (and charges much more slowly.)
