Fast car and home chargers (full 1 amp)?

So I bought a car usb charger that claimed it was rated at 1 amp. Using both my blackberry and HTC oem usb cables it will only show up as a USB charger (500ma).
This is not exactly enough to charge the phone while using 3g, gps, full screen brightness, etc. I'm looking for a good confirmed 1 amp hardwire (not using a usb cable) car charger and home charger. I used my sisters Samsung charger (rated at 700ma) and it charged it quicker than with the OEM htc charger.
And I would like to try and get ones that are confirmed to show up as fully charging the phone. I would appreciate some insight

And now that I think about it,
I would like to be able to use my Amazon prime for a change, so amazon links would be nice

I went through a few different car chargers, so I can help you out here. I bought the Belkin car charger recommended here in another thread, low profile and rated at 1A, but my phone only recognized it as USB and charging was fairly slow, extended road trips using video recording and navigation while plugged in would drain my battery over time.
I used my friend's palm pre home charger and it worked very well, so I went on to Amazon and bought the "palm vehicle charger". The one I got in the mail (from Park Deals) was DOA, wouldn't turn on at all (I emailed Park Deals and they sent me a new replacement free of charge, didn't even have me ship back the defective one). I called the local radio shacks and found one in stock at $9.99 (radio shack isn't carrying palm anymore, so the accessories are on closeout but hard to find in stock). Works like a charm, the phone recognizes as AC charging, the phone still charges while running navi or recording video.
My friend got a cheapo car kit on ebay, came with rubberized case, mount that fits the evo with the same case on, and a cheap unlabeled car charger with a bungie type cord. I tried this on my phone, my evo recognizes it as AC also, so I assume it would charge well if it's rated at 1A. I've seen several other cheapo car chargers rated at 1A as well.
Another thread here on XDA says that if you modify your charger/cable by altering the middle data pins you can get the phone to believe the usb port is plugged into the wall and draw full current from the charger. I tried covering the two middle pins with a piece of paper and plugging it in, but this didn't work for me. The other methods involved shorting the two data pins together, I didn't really want to waste a cable or mess up a charger and potentially my phone so I just bought a different charger. Another thread mentioned buying a specific rocketfish usb cable had a similar effect.

That was me on both accounts. Love my rocket fish cable. Bought the 12v/usb converter for the car and whether or not i use the pc or car to charge, it shows as ac charger on the phone. I use this cable on all my pc's as well as the usb outlet in my vehicle.

This is the charger that I bought from amazon. It shows up as charging from AC (instead of USB) charging. It's available for Amazon Prime for under $6:
The Motorola P513 micro-usb charger.

Ok so I ended up with the Moto 513 charger as well (950ma rated)

How fast does it charge?

One the 2.1 amp port, the Evo only charges at 1 amp. The Evo doesn't charge any faster with this charger than any other 1 amp charger.

Gotcha, thanks for the info.
I just ordered a Rocketfish cable. We'll see how that works.
Would be nice if they made a Y-cable to get 1amp from 2 USB ports in a PC. I mean, I know they MAKE cables like this but I read somewhere that HTC phones were designed to still only charge at 500mAh even with one of those.
Dunno.

It depends on what you're using as a charging source. When usb charging on my home pc or car, it's AC charging at 1 amp.. But if I'm charging with my Energizer external battery, it's only USB charging at 0.5 amp. This is using the same usb cable.

iGo
Would anyone happen to know what an iGo tip (A97) delivers? I am trying to rig up a custom solution that is hard-wired, but uses iGo tips so I don't have to use the cigarette lighter plug and I have the flexibility at the corner of my windshield to swap tips for different devices.
Right now, I have a 4-port USB hub installed under the dash that is 12v powered. I then use a proprietary iGo cable that uses a standard PC style USB connector on one end and then terminates into an iGo tip connector at the other end. That USB cable runs up to the corner of the windshield so I can swap tips at will.
If I use the iGo A97 tip on their cigarette lighter adapter, it seems to charge, but I am not sure at what rate. If I try to use the A97 tip on the USB hub, it charges for about 2 seconds, and then the light goes out. The Evo does not seem to like the custom arrangement, yet all my other micro usb devices do not seem to have any issues and charge just fine...
Thanks,
-Rob

I can attest to the Moto 513 working fine - it has served me very well on my Evo and the Treo Pro before it.
Unfortunately it is a big ass charger though - wish there was a good micro option.

How do u determine how much power its actually charging at or if its not using the full 1amp rating?

USB Cable / Car Charger / Wall Charger combo

Hey guys,
Looking for a combo micro-usb wire that also comes with a dual car/wall charger. I dont care if its two pieces or three pieces, but I just care that I can keep the Captivate plugged in and not have any issues using it. The last one I bought was a Duracell three way usb combo that had a retractable wall charger on the travel charger piece, but it wasnt giving enough power to the phone, so i couldnt use it while plugged in.
I have been looking at the "Premium USB power kit" by A Days Tech on Amazon, but im worried its going to be a generic POS and not give enough juice.
Anybody know which of these works?
I guess I can also buy a high quality micro-usb wire and then a high quality USB car charger/wall plug seperately as another option. So any opinions on those are also appreciated.

There are a bunch of threads on charging these phones. Unless the charger or the cable has the data lines shorted, the phone will only charge at USB rate (~500mA). Even if you have a 1A car charger, the best you will get is USB speed UNLESS you connect the data lines on the cable. I have not seen a car charger that does this.
The most current the phone will draw is around ~750 mA. It will do this when it thinks it is attached to AC.

Hi,
I bought the Scosche HC12V Dual Home Charger, but I haven't received it yet, but from what little I know of the brand they supposedly make good accessories. I should receive it in a few weeks (shipping a captivate and accessories overseas).
Both outputs are rated at 1amp, the only thing is that it does not come with it's own cable.
http://www.amazon.com/Scosche-HC12V...X0DER&s=STORE&ie=UTF8&qid=1285613609&sr=1-207

I bought a car charger and separate car-to-wall converter from Monoprice. Total for both items about $5. Maybe it only charges at 500 mA but seems fine to me.

What is the BEST charger that is CONFIRMED working? I'm tired of buying and wasting money on chargers that are junk. Thanks!

I've found that most car/travel chargers are rated for .75 amps, I was surprised to see that the GN uses a 1 amp desk charger. Fortunatly, a while back, I got a good sale on some of these micro car chargers. I picked up a pair. My model is older and only rated for 1 amp, the newer model is rated for 2.1 amps, if my 1 amp can keep up with navigation mode, the higher rated one should do you fine. As an added bonus, it sits totally flush with the lighter outlet.
The only downside is that you need to provide your own cable. I got a left turn usb cable to keep things tidy

I'll pick that bad boy up. That's EXACTLY what I probably need to be using. Does any cord work? Or should I get a real good cord too?
Ordered: Kensington K33497US 2.1 AMP output. I feel bad that I have to use a charger that powers an iPad to power my cell phone.. something isn't right

I'm using this. Works great, 2 USB.

While plugged in if it says "Charging (AC)" you're charging. If "Charging (USB)" you will slowly loose power while plugged in.

I look at it as poetic justice.
As for the comment about USB charging vs AC charging, mine charges as AC, if for some reason you get USB, just short out the 2 data pins on the USB cable and you will be good to go.
I don't think you need a high quality cable. I was specificly looking for one with a right angle turn right at the plug so that the wires don't stick out in all odd directions.

Car fast charger?

Does anyone have a car charger that works with fast charging? Or any recommendations on one that will work?

If you're looking for wireless I don't think there is anything out there right now. I bought the iottie like a day or 2 before news broke of the speed reduction. They say they are not going to go for certification. I have an email out to Anker's marketing team.

there are tons of type c options out there, personally I'm using the PD charger from choetech. anything rated for either 3a/5v or PD will fast charge. this is the one I'm using:

Here's a couple I would trust
Choetech 18 watt USB-C PD & Aukey 27 watt USB-C PD / 39 watt total
My other posts were about wireless quick charging. I got that on the brain, apparently.

Yes - I use the Iottie One Touch Wireless Charger and it works GREAT for every phone I have used it - including my Pixel Xl 3
It is a little pricey but it is the most versatile charger I have found - and it is very user friendly - for taking the phone in our out of the phone holder/charger.
I also really like the Iottie Discs they include with the charger/holder - it allows you to mount the charger/phone mount on a curved dash without any problems at all - and in a pinch, they can be removed without messing up the dashboard. Great Charger - great Car Phone Mount. Really is the best one I have seen

tried out my choetech 10w wireless car charger. didn't mess with any measurement apps since I knew it wouldn't charge at 10w, but it did charge the phone with navigation running, screen on and music streaming over bt. since it's powered by type c you can always just plug the phone in directly if you need fast charging, but if it outpaces navigation that's generally good enough for me.

I've been using a 10w wireless charger in the car and it works with Google Maps navigation and Bluetooth audio running. It doesn't charge fast but not having to deal with magnets is nice. The only issue is that if you turn the car off the arms won't open at the push of the button. Not a big issue because the pho e is easy to take out.
If I do need to fast charge I just place the phone in the crawl then unplug the power from the car charging mount and straight into the phone. I'm using a USB C PD car cigarette lighter socket.

Does it still charge and maintain a charge while using the phone for streaming/nav, etc?
Oh, and will it work if my XL has a bulky case?

I have a question.
See it's nice to have wireless chargers in the car with arms to hold the phone. Even better to have a wireless charger with magnet.
Now I won't go in debate of over charging the phone but is there a wireless charger for a car that has a button to turn ON and OFF the charge? I don't care with or without a magnet to hold the phone.
I drive allot so I don't mind a slow charging the phone, I do care about leaving the phone on without over charging it. Plugging the cord in and out isn't fun.

it does charge while using navigation - and Wireless Android Auto - (which is a pretty big drain on the battery) I don't know about a "Bulky Case" I use the Ringke Crystal Fusion Case" which is fairly thick - and it works fine for me - but I haven't tried any other case, so I can't say for sure.
I love the Iotti One Touch - Wireless - it is an awesome holder/charger
Good Luck

Granted i will have to install or use two side tape to attach two metalic strips onto the phones case to get the magnet stick to it. Should be piece of cake or buy those metallic rings that sell and attach them.
there is also this one, but sadly it doesnt come with a suction cup (which i really need) I does come with a metal ring tho.

Car charging issues (standard S20 5g)

So i've had this phone for a few days and took a road trip and camped this weekend. To say the least, I had a good feel of battery usage of this phone for my typical tasks.
During my road trip, my phone started with about 92% when i threw it on the charger and started driving. I noticed it was charging up to 96% and it started to discharge slowly after about an 45 minutes of driving The phone indicated it was being charged. When I purchased this phone I also purchased a 6a car charger (dual port, 3a each), and also some USB-C to USB-A cables rated at 18w. If I disconnected the power for a little bit, and reconnected, it would charge maybe 3-8% before stopping again and I would repeat the cycle to ensure I had enough battery to allow navigation to take me to my destination. Luckily, I made it to my campsite with 82% battery to spare.
Now the strange thing- when I left this morning to come back home, I had 100% on my phone as I charged it with a battery bank fine. I left the phone plugged in to my car charger as I left, and it stayed at 100%. I even let the phone discharge to 94%, and plugged it in and it was able to charge to 100% with the navigation on as well as pandora.
Am I doing something wrong? Am I supposed to be using a USB-C type charger? Maybe I need a better rated cable?
Would love some help. I'm coming from an S7 edge so a lot has changed. thanks!

It's a qualcomm based charger. https://www.amazon.com/AILUN-Charger-Qualcomm-Adapter-Compatible/dp/B01N8PPY1H

Sometimes while driving these things can work loose in the lighter socket, a slight touch fumbling around near it (my dash cam does this), or some bumps in the road.
I suspect on your outbound trip the charger might have been getting intermittent power from being not quite pushed "home", but on the return trip you could have pushed it in harder and it stayed put.

this wasn't the issue as I tried unplugging it and tried various 12v sockets in my car. However I think I did figure out my issue. The new charger i'm using does not use the "PD" protocol that the newest samsung phones use. Also, although the car charger i have is a qualcomm 3.0 protocol, and 36w- it's actually at 18w per usb A socket. The s20 wall charger is rated at 25w- so I'm now looking for a usb car charger that has a dedicated usb c socket with at least 25w of power and supports PD and pps

I've reconsidered using fast chargers after the purchase of the S20, we've started using old 7.5W and 10W AC power adaptors. The 7.5W charger brings the phone up from about 30% to 80% in about 75min and I am fine with that. I have also used the 5W S3 charger but I think I'm happy with using the 7.5W charger.
If I need a fast boost I can always pull out the 25W charger.
I did buy a Belkin 18W PD car charger with the phone thinking "yeah, I need this" but now I will only use it for emergency charging. Tomorrow I'll pull out an old 10W car charger and plug the phone into the 10W socket while I drive around, see what happens.

Well I got into the car at 10:55 with the battery around 26%, plugged it into an old car charger I bought for our S4s (Pleomax, apparently OEM for Samsung) which has 2A & 1A outlets. It's not obvious on the charger which outlet is which but turns out I used the 1A outlet (AccuBattery showed the charging current hovering around 1000 mA).
Anyway, after 1hr of driving to my destination with a 5min break to fill up, the battery reached 66% so the 1A car charger raised the battery by 40% in about 60min, which I think is quite acceptable.
Car connected by BT for phone/SMS, received 1 call only. GPS/NFC etc are usually kept off.
