How to charge with a higher current?

When using my Toch Diamond as a GPS which is connected to a car charger, the battery will run flat in a few hours. Is there a charger that will charge it with a higher current than 500mA? It is inconvenient for a long trip.

Wait ..... you are saying that your GPS app runs your battery down even while plugged in the car charger?
Mine doesn't do that...

Are you using an original HTC charger?
Some of the generic after-market car chargers output a lower current than what the GPS is actually draining from the phone, so effectively, rather than just charging it, that charger is simply "extending" the time it takes to drain the phone battery.
I'm not near my HTC car charger at the moment, but if I remember correctly the HTC charger outputs 2A.. ie, 2000mA? (can someone correct me if I'm wrong?) And I have no flat battery problems while using TomTom... (The fone does get warm, but that 's another issue that's been discussed previously...........)

Most car chargers only do 500mA
When using good navigation it will pull more than 500mA off your phone, so eventually, the phone will drop dead It's true, I have this too.
With an other ROM it can be fixed! Now I don't have this problem anymore. You can also connect 2 chargers parallel but you got to have the possibility in your car. Or you buy a universal USB car charger which can handle 1A. Just like home wall charger (No 2000mA ).
Good luck!

My car chager (with a mini USB output plug) is rated at 5V 2A. My suspicion is that the charge current is determined by the phone, not by the charger. The charger is simply a (constant voltage) 5V power supply. Even if the chager is capable of supplying 2A, the charging circuit in the phone is limiting it to a maximum of 500mA. If the phone is designed clever enough, it could allow a higher charging current though signaling via the two signal wires of the USB plug. Would anyone know if this is the case or not for Touch Diamond? If yes, what would be the signals for higher charge current?
Your idea about using two chargers sounds interesting. Would you be able to give us more details about how to charge one phone with two chargers? Or are you thinking of having two phone and two chargers? That is, after one phone battery gets flat, simply uses another phone.

Confused
I have got an O2 Ignito (diamond) I have done an 8 hour round trip using GPS and my battery has not drained... And i do have the original I am using the charger that came with my polaris. my batt always stays full when plugged in and gps is running maybe your charger is what is causing it to drain

Needs a 1 amp charger.

New wireless charging chip, same speed as wired charging?

just spotted this
http://www.qiwireless.com/toshiba-starting-production-faster-wireless-charging-chip/
Wireless charging at wired speeds. I am avoiding wireless charging due to the slow speed of it but if this thing works I wont need to avoid it anymore.
When available, would this work with an S5? It says it uses Qi as "its base for wireless charging". This is unclear to me, does this mean it is a Qi charger or that it simply uses some Qi stuff and then goes beyond it to provide the extra power, so it isnt actually Qi at all (if Qi is a standard then I assume this new thing doesn't confirm to that standard and so it isnt Qi, in which case it wont work with existing Qi devices?)?
What I would also like to know is does this new chip need to be in the phone itself, or would the chip they talk about be inside the back cover, or in the charging pad? Obviously if the phone itself needs to support this specific chip then its not going to be any good for s5 users, but if it is independent of anything in the phone and work would on an s5 then it may be worth waiting for it, it is apparently already in mass production so should be around soon I guess.

Based on the (albeit limited) numbers they provide in the article, it appears this is still a low-power Qi spec device like the ones we have today, which have a maximum output of 5W.
The wireless charging integrated chip will be following the Qi wireless charging standard as its base for wireless charging, which is great since this is currently the most used wireless charging standard for current devices. Along with this, the chip will be able to have a maximum output of 5 watts, which is comparable to a wired charger.

Unfortunately they say nothing about how this would differ from your run of the mill ebay Qi solution.
Mathematically (which admittedly is not my forte), if we assume "Wired" charging rate is 1800mA, 5W @ 5V requires 9W to hit 1800ma, which is outside the low-power Qi spec.

Then it is even more confusing as the entire article seems to be suggesting that it will charge at the same rates as wired chargers and much faster than current Qi systems.

Standard wired charging rate is 1amp, at 5v that is 5w
So if the new induction/wireless charger can supply 5w that means it will supply 1amp which is the same as wired
These will be roughly the same charging speeds

by the way, if you look at the charger your phone came with it clearly says "5.3V and 2A" so no the wireless charging will not compare to the conventional wired charging using your stock charger

This is correct, sorry should of also made my post more clear
5v 1amp is most common on many devices now and the qi statement relates to many devices so technically what they say is right BUT now some devices including the S5 do use slightly higher voltages and some draw more current now meaning wireless charging on our device will not be as good as wired BUT for most people that simply charge overnight it will make no difference
Those that charge overnight wireless charging will be perfect
Those that excessively use their phone and need as much charge as possible in short periods/quick charges throughout the day etc should use wired charging

Anyone have luck with wireless charging receivers?

I recently got a wireless receiver and charger off Amazon, but haven't had any luck so far. The phone days it's charging, but overnight the percentage never changed. Assuming it is just such a slow charge.
Anyone have a better experience?

HTC U11 does not support wireless charging. Did you do something to add wireless charging to it?
EDIT: Sorry, missed the part about you using a wireless receiver. It should work. Maybe try on a different charger to isolate if the issue is with the receiver or the charger.

Very slow charging
I bought a wireless charger adapter that plugged into my usb-c port and used it for about 3 months. It charged very slow and I soon gave up on it. It did not charge as slowly as what you reported though.

Seeking Recommendation for Power Delivery Car Charger

Seeking recommendations for a USB Power Delivery car charger (for rapid charging). Ideally I would like something that's low profile so my console door can close over it when not in use

I have this. Nice to have a QC3.0 & PD3.0 USB options on the same charger. Meagoes car charger model CC003
No wires included tho

No wires included is just what I was looking for! I have so dang many - Thank you!!!

I'm curious if anyone has used any of these chargers for the Essential phone. I'm probably gonna grab the second one I link below and will test with my usb-c power meter and report back when I have time but if anyone else has direct experience I'd love to hear it.
This one looks a lot like what we need but it oddly states "not compatible with Essential" though there are reviews stating it does and does not work
https://smile.amazon.com/Nekteck-Ce...coding=UTF8&psc=1&refRID=RH73X9QDHJD8QPDN6DHG
This one has a little more power than the previous and does state that it works with essential though it claims that the PH1 negotiates via the 12V rail instead of the 9V meaning it is pulling less than 3Amps and therefore flags on the lockscreen as "charging slowly" even though it does charge fast.
https://smile.amazon.com/Nekteck-Ce...coding=UTF8&psc=1&refRID=RH73X9QDHJD8QPDN6DHG
This one is a nice looking wall charger but also oddly states not compatible even though it has the right specifications.
https://smile.amazon.com/Nekteck-Ce...coding=UTF8&psc=1&refRID=RH73X9QDHJD8QPDN6DHG
This one is wildly overkill for the PH1 and also states it has the same 12V rail thing as charger 2
https://smile.amazon.com/gp/product/B0721KG2Q7/ref=?ie=UTF8&m=A3GMRWNJ2V9TRM
This one has a built in cable but also states the same 12V rail bug
https://smile.amazon.com/gp/product/B0719KV9PH/ref=?ie=UTF8&m=A3GMRWNJ2V9TRM

So update...
I bought these two chargers off amazon, buy the car charger and the other charger is 50% off.
Both show charging rapidly when connected to the Essential phone so whatever mistake there used to be with it selecting the wrong rail or it not being reported correctly seems to not be an issue on oreo 8.1. I tested both with my usb-c meter and they seemed to provide something between 5 and 9 volts and anywhere from around 1 to 2.6 amps depending on charge level of the phone at the time.
Over all these seem like solid chargers and they are USB-IF certified so in theory the manufacturer isn't playing fast and loose with the charging specs like some do.

looks like monoprice is in the game now:
https://www.ebay.com/itm/27W-Car-Charger-with-USB-C-and-1A-USB-A-Ports/391954642515
weak usb-a, but usb-c supports [email protected]=27w

I bought this one
https://smile.amazon.com/gp/product/B079MWXSS8/ref=oh_aui_detailpage_o00_s00?ie=UTF8&psc=1
27W on Power Delivery and ~10W on USB-A
Has 45 day money back and 2 year warranty.
It costs more than the others, but I've never had an Aukey charger go south.

I got a https://www.amazon.com/Trianium-Charge-Charger-Samsung-Nintendo/dp/B01LXY0ECN . It has QC3.0 and PD. Works very well for me. Not the cheapest and it's one of the few which works very reliably after trying out more than 5 such chargers. Some don't supply enough power, some says they are PD but yet charges slowly. Only this one really worked for me. It's almost $20 but worth it for me

Question 25W magnetic wireless desktop charger ??

Hi,
Does anyone know if such a thing exists ? It seems that the only magnetic wireless desktop chargers are for iphones and hence seem to top out at 7.5w. I have bought: https://www.amazon.co.uk/gp/product/B08S6XQFDM Which allows you to sue magnetic wireless chargers, but I'd like to get one that can utilise the 25w charging capability of my new Z Flip 4.
Any help or advice would be very much appreciated !
Thanks in advance,
Jeremy

Just to clarify, 25w is only wired charging. For wireless, max is 10w only so look for qi magnetic chargers for that speed. This one says it can do max 15w wireless https://www.amazon.com/Universal-Positioning-Placement-Operation-Compatible/dp/B096W24V1H

Thanks NguyenHuu - good to understand that clarification. Will take a look at that stand.

As far as I can see in the available specs, the wireless is up to 15W and this is something that I'm actually seeing (without the actual current measurements, just perceptibly) - the phone seems to charge quicker on my Samsung 15W QI charger than the Flip 3, which supposedly had 10W wireless charging. The brick for that charger is also 15W, so it seems legit.

I'm using a generic 15 Qi watt wireless charger from Amazon. Was dirt cheap, Did not come with wall plug. Using a generic 25 watt charger (same specs as Samsungs wired charger) my phone reports charging from about 12 -14watts. Charges up quick. Why the 25 watt? The old wall plug I was using was 10 or less and would take all night to charge if 35% or less left on battery. So if you use Qi 15 watt wireless, just make sure your wall plug is up to speed.
PS that free flip case they gave out with the strap and metal lug will not allow wireless through it. Case and strap too thick. Probably why they are dumping them for free.

Yeah, the rapid wireless charging is the thing I will miss most about the Pixel 6 Pro.
