2A carcharger possible

Hi all,
Maybe a stupid question but I simply don't no the answer
Is it possible to use a 2A car charger for the TP (with a 1340 mAh battery)?
I found one on ebay:

Is the TP protected for overload?

Only one way to find out. Wanna be the the guinea pig ? XD

I think it doesn't care, because there is an charge electronic in the mobile which regulate the charge current.
Maybe your charger can charge by 2A but the mobile will consume just 1A.
By the way: I've got a charger with 0.5A (not original from HTC) which doesn't work with the mobile at all.
with my mp3-player there is no problem.

Lol, it does not work that way with amps, although it DOES work that way with voltage ! if you put to many volts in you will damage your device, however if it is the correct voltage but very high amps your device will be fine, all that will happen is the device will take the current it wants and just leave the rest. infact if you have enough current (as in this case) you could charge two devices simultaneously, and they will both charge as quickly as when on the supplied home charger.
basically what doc said above !

Thanks for the input! Glad that 2A won't affect my TP.
Too bad though that TP won't charge with double speed (2A instead of 1A). Full in just half an hour would have been great...

High powered USB car charger?

Hi all,
Can anyone recommend a high mAh output usb car charger? It has to be one with a detachable USB lead.
The one I have currently takes forever just to charge the device by a 1% increment. It doesn't also seem to provide enough power when for example I have sat-nav/GPS running (the device still drops in battery power).
Thanks.

dont even think....
dont even think about it.... i got a charger that does 2 amps instead of 1 amp and guess what my battery blew up!

So what's optimal/maximum amp rating that I can use?
The one I have I would say is pretty much useless when using battery hungry applications/services.
Just tried to check my existing charger but there is no rating on it.
Would I able right in saying the following:
A charger with a 1000 mAh, would charge my battery by 1000 mA in a hour?
I believe HTC official chargers have a rating of 1000 mAh too right? Mine one may well be 500 I would guess.
How quick do other peoples car charger charge their Diamonds?

A charger's specification would never indicate the mAh ( milliamp hour)rating, but would indicate the maximum current it can supply while maintaining an operating voltage (for usb its 5Volts.)
in answer to your question: yes your charger needs to supply more current when you have your Diamond operating and charging at the same time. not all chargers are made equal. some may max out by 500mA, therefore your diamond wont charge at all if its on. as far as I know, most chargers are rated to supply 2A (or 2000mA)
another thing: your diamond uses its own charging circuitry to recharge and maintain its battery. just because a charging adapter says it charges at 1000mAh, i doubt it would actually recharge your battery from 0% capacity to full% capacity in an hour(it just doesnt work that way, and if it did, then your battery could blow up).
as for my own diamond, i seems that it takes around 3-4 hours to get from 0% to full when it is off and using my stock 950mAh.
doing a little math here: 950mAh / 4 hours = ~250mA
therefor in order to recharge your battery, the charging adapter needs to supply 250mA.
but if your diamond is ON and you want to recharge then your charging adapter needs to supply 250mA AND and additional amount of current to maintain your diamonds power.
if youre still able to follow with what im saying here, you may conclude that you just have a DUD charger and you should just buy another one.
as for the other guy who said that a 2Ah charger blew his battery up. I'm a bit skeptical. I think your chargering circuit in your diamond is more likely to fry before blowing a battery up (and if a lithium battery blew up it would have taken out his entire diamond).

Yep, that all makes sense.
By chance, My battery (1800mAH) totally died last night. Put it on car charger and after almost exactly a hours worth of charging, the battery indicated 1% (!) Mind TomTom was running for about 30 minutes of that.
Ok time to buy a new higher rated charger I think. Any recommendations for one with a USB port on it?
Thanks.

i've been looking for one liek that on e-bay as well but i cannot seem to find one. having a detachable usb cord would be nice, but now that i think about it maybe i am better off finding one with a non detachable cable in the event that I dont have a usb cable around.

Yeah, I wouldn't normally mind one with an attached cord but the setup in my car is such that I already have a semi hard wired a usb from a 12v supply and have the [USB] cable hidden then have it pop out near to my car holder.

bingo

Check out Avantek. This charger works so much faster than any other charger I have. My Note goes from zero to hero in no time flat.

Is this safe? Solar power charger

I was out of the country recently and could NOT get to a charging source. So i was wondering what if i had one of these in my backpack? Would it be safe for my phone or would it mess it up because of the charging output?
http://cgi.ebay.com/ws/eBayISAPI.dl...&ssPageName=ADME:X:RTQ:US:1123#ht_2692wt_1202

Since our ac charger output is at 5v 1a or 1000ma....
Its weird this charger output is 5.5v. Most I've seen are 5v output.
My friend had one from another brand with 5v output no problems.

If it were me....
I wouldn't use that charger if it is pumping out 5.5v. The batteries in the phones are LiPo batteries which need to be charged in a very specific manner. If they are over charge or under charged it can and will do permanent damage. And if the OE charger is 5V i wouldn't risk it.

Don't go cheap when you consider solar/power pack options. You need to consider the power output of the stock usb charger and try to stay as close to those numbers as possible.
I've had a solar panel setup from Brunton for several years and it's excellent quality and provides the power needed via a car cigarette lighter outlet. 6 watts is the lowest output rating I would go (500mA @ 12V). I bought my first one for $106 when the Dell Axim x50v was a new product and even bought a 2nd one (last one moontrail had for $89.95) for my emergency survival pack. Excellent camping/hiking accessory I wouldn't be caught without, especially with power-hungry GPS devices.
Here's a link to what I use: http://www.moontrail.com/brunton-solaris-6.php
I've tried several rechargeable battery packs and had to return them because the only pack I've found that would charge my phones more than once was purchased several years ago, from PPCTechs.com. It cost me $60 (from what I can remember) and is rated @ 4400mAH and charges it at least 3 imes. They don't carry the product anymore...
When it comes to solar power, you're going to have to pay a little more money for reliable products...

Solar Charger

Someone knows any Solar charger that really works with HTC Desire?
I look in www.dealextreme.com but I don't know how many "Amp" need the desire.

all solar chargers i've found so far had an 80mAh ouput.
a usb charger has an 500mAh output and charges slowly around 4-6 hours? (never tried to charge it full via usb).
a wall charger has up to 1000mAh and charges the phone in 1-2 hours.
so i guess it takes the solar charger virtually forever to charge your phone once

Yeah, generally you want a charger with high output (at least 500 mA) and a high capacity (at least the same as the desire battery, which is 1400 mAh). Once you're sure about those two factors, you're safe.
I'm using the powermonkey explorer: Link
Output: 700 mA
Capacity: 2200 mAh
On a sunny day, I'm able to reach the maximum charge in one day (10-12 hours sun). Note that the output from the solar panel to the powermonkey battery is a lot lower, more like 200 mA. And a full charge should, in theory, give your phone 1 and a half charge. In reality it's more like 1 charge, which is still fine.
It might be a bit more expensive, but it actually works.

heh good point !

if you ever find a solar charger post it in this post where you've got it from would love to try this lol

Gizmodo reviewed this charger a while back. Quite tempted to buy it myself

These two work with desire?
Which would you choose

To use it effectively you need to use a solar charger with built-in battery.
E.g. I got an Energy Trends ET-3000:
http://www.energy-trends.eu/et-3000-solarladegeraet-iphone-handy.htm (maybe use google translate) 330mA solar power, 3000 mA battery, 1000 mAh can be loaded within 3 hours in direct sunlight
Can also be combined with this:

Arctic C1 mobile
I found this charger: arctic.ac/en/p/power/batteries/44/arctic-c1-mobile.html?c=2224 which I quite like, but
the question is: would the 5.5v output "fry" my HTC?
I tried a 3rd party usb power adaptor, which outputs 5.3v as opposed to the genuine HTC adaptor (5.1v) and the phone can't be used while it's charging.
Literally the phone becomes so unresponsive, that it's impossible even just to slide the keylock! The minute I put the phone back onto the genuine HTC usb adaptor, everything works fine and I can use the phone while it's charging.
So here is the second question: has anyone experienced this?

this one looks excelente,like germany tanke.

i dont think thats a good gadget. the usb charger does not load the desire complete full and the accu is really fast empty.... so i dont wanna buy such a gadget.

Could be so interesting for long travels

Looks interesting, if someone could share his experiences about it!
I would be gratefull

works?? Have you bought anything? Thanks

USB Car Charger @ Lidl(U.K.) £4.99

In case anyone is considering purchasing one of these device here's my experiences with it so far.
The description on the box specifies that it will deliver up to 1.2 A. The TouchPad (in Webos mode) complains that it isn't delivering enough power but it is definitely charging the TouchPad and charged from 91% to 100% within a half hour( That's how long I left it before checking it again)
Here's the link http://www.lidl.co.uk/cps/rde/xchg/lidl_uk/hs.xsl/index_28570.htm

It will just charge slower of 1.2A. If you want it to charge faster get one that supplies 2A, but if you are okay with the slower charging rate then there is no need to get a 2A charger.

Im sorry but this is not the case!
This advice keeps cropping up and is incorrect.
Any 2A charger will NOT give full rare charging due to TP signaling requiring the correct response from the charger and the only one on the market that will respond correctly is the HP charger.
Others will charge but much more slowly and if the TP is in use probably nor at all.
This info really should be in a sticky to prevent confusion and misinformation.

I am sorry, but some of us are just quoting what we find in practice rather than what may be documented somewhere. I find my Blackberry Playbook 2A charger on a timed test charges at almost exactly the same rate as the HP charger (checking % per hour over at least 50% charge difference). I have a 1A no-brand charger and that is very close to half the rate. Maybe my two branded HP chargers are faulty but I have no issues with the rate of charge with any method I use, including from a PC USB Port (which clearly is much slower and barely makes a difference if the TP is on).

I'm not saying this or that charger wont charge it just wont give the full charge that the HP chargers give.
And its not just a matter of opinion. The HP barrel has been dismantled to show that there is signaling circuitry which no other charger has.
Ipads use a similar setup only using signals of a different value to do the same job so unfortunately they are not "compatible" either.
This is done to establish a correct "handshake" which safeguards the device and charger. An incorrect setup could fry the circuits in either the charger or the TP or both.
When in use the TP can be pulling 1A and so require the other 1A to make sure of a positive charge so if you use a lower powered charger or one that is not fully compatible even if its rated high enough you wont get any appreciable charge to the battery as the TP in use would take all there was available.
I'd you were to use these other chargers when the TP was not in use then yes there would be a positive charge albeit slower than with the stock charger.
HP made it that way for the safety reasons mentioned above.
I'm not trying to dis anyone. Its just the physical properties of the circuits.
