I use my old Motorola mini-USB supplies and love 'em but would like something with more juice than the ~800mA they put out. Any suggestions? I can occasionally find a folding-plug power supply but then the max current is never specified
TIA,
Richard
Closest I know of is Boxwave's VersaCharger Pro which supplies 1 Amp, which I've found sufficient for charging my Tytn II.

Yeah, that one is interesting - a little bulkier than I'd prefer. I have to do some testing, but I recently discovered my ~800mA Moto charger won't charge my APC USB battery when it's completely discharged. I've not noticed any issues with my Hermes or Kaiser, but I don't let them get to 0% and I usually can wait overnight when they're really low.
It was a pretty unhappy discovery that my current supply wouldn't charge that battery! Luckily I had my laptop along and it *would* charge from the USB port - which can probably supply 1A or more.
I'd like to get a nice 1.5-2A supply and at least *know* that I wasn't hitting a current limitation

I saw this Griffin Powerblock Universal at my local Staples, and the box said 5V @ 1A:

That's a lot more the desired form-factor, but still shy of what I wanted.
I may snag one anyway just to see.

Actually, most, if not all, computer USB ports are limited to 500 mA -- to get 1A you need a powered hub.

I'm not convinced of that. Yes, the spec is max 500mA and I've sometimes seen some machines pop up and complain about overcurrent on a port, but many other times not. I'm also not 100% convinced that all my laptop's USB ports are directly off the chipset - so there may effectively be a powered hub involved here. I guess I'll have to carve up a USB cable and put a current meter in there to answer the question one way or another - don't hold your breath on that one
Richard
A couple of things:
As far as USB port power goes, I've read up about this (forget why), but the USB spec DOES say that each USB port needs to supply at least 500mA... But in practice motherboard manufacturers tie the power lines of multiple ports together, so if a motherboard has 4 ports, the power bus will be connected to all of them, and it will supply at least 500mA x4, or 2000mA (2 Amps) total. There is generally no individual regulation of this however, so if you only have one device plugged in, it has the full 2 amps to draw from. Often other devices like mice or keyboards use so little power that there is plenty left for other peripherals to use well over 500mA even when all the ports are in use. This is actually a problem, as many product manufacturers get "lazy" and design products that actually NEED more than 500mA, especially things like bus powered hard drives, because those work on most systems (but frustratingly, not all).
As far as power supplies, i got curious, and here's what i found:
The exact power supply that comes with the tilt is about $8US from mouser in the US:
http://www.mouser.com/search/Produc...irtualkey55210000virtualkey552-PSA-A05A-050-R
it's mouser part number: 552-PSA-A05A-050-R
Sadly it doesn't fold and it also only provides 1A, so, here's some more stuff:
This part is similar but just has a USB port on it, so if you already have the data cable with you, the AC adapter won't take up much more space:
http://www.digikey.com/scripts/US/DKSUS.dll?Detail?name=T1003-ND
Now i'm really not having any luck finding exactly what you need, but if you're a bit handy you can wire a mini USB port onto another 5v power supply with more current output. I can't tell you which wires go where but if you have a multimeter and a soldering gun you should be able to figure it out:
here's a USB mini cable with wires coming off one end if you don't want to cut up a cable you already have: http://www.digikey.com/scripts/US/DKSUS.dll?Detail?name=WM17104-ND
And any good regulated or switching 5v power supply should be good. Here's one with 2A output, and it's described as "flip out", so i imagine the connector, um, flips out, but it's not a stock part so you'd have to call them, and i don't know if it's regulated or switching (either is good, i think), so you should ask: http://www.digikey.com/scripts/US/DKSUS.dll?Detail?name=T321-P5P-ND
an in stock, non-flip out one is here:
http://www.digikey.com/scripts/US/DKSUS.dll?Detail?name=T450-P5P-ND
If you custom wire one, test it on a less important device, just to make sure that it really will be okay, and don't sue me if it breaks something. Plus, i don't know how the kaiser feels about charging at more than 1A, since the stock power supply only provides that much current.
Also, another kind of plug is the "multi-plug" power supply, with removable plugs to allow for plugs from different countries to clip on, so rather than flipping out the plug, you could just unclip it, if you don't mind having 2 pieces. Here's one of those at 1.2A and $13US: http://www.digikey.com/scripts/US/DKSUS.dll?Detail?name=T946-P5P-ND
or 3.2A at $18US:
http://www.digikey.com/scripts/US/DKSUS.dll?Detail?name=T377-P5P-ND
But you might want to call HTC and talk to an engineer (they're hard to get a hold of, but i've been able to do it at other companies if you keep asking) and make sure that higher charging currents are okay.
And i really only checked mouser and digikey for these things, so it's possible that other suppliers might have something different, though they are two of the largest suppliers of this kind of thing in the US, so i'd be surprised.
You could even call CUI direct and speak to someone there, they're nice people and they might be able to make you a custom one for not too much (i doubt they'd do that for one unit, but if they already make something close they might!).
If you can't get what you need easily, try harder! Hehe.

Hi,
I am looking to buy a car charger for HTC Fuze
There are so many listed like at Eforcity and BargainCell
would anyone of them is fine?
Is there a decent place other than those two? Above places are just charging more on shipping than the actual cost of the charger
Thanks
The easiest way would be to swing by an ATT or Verizon store.
I do have several and they are all rated 5 V (rarely you'll find 12V) but use one of these. They are pretty slick because you can charge ALL USB devices and, if you travel, it's a "one-for-all" device (meaning I can charge my headset which has a USB cable, iPod Nano and the phone.
http://www.daydeal.com/product.php?productid=10892
If you travel a lot you may look into one of these as well
http://www.bixnet.com/usbbatterybox.html
There is also one which does both, AC and cig. input to USB output, a little bit bulky though, but I couldn't find the link right now.
how is that compared to this one
http://www.amazon.com/Charger-Generation-Antenna-Booster-Google/dp/B001LP2ME0/
Comparison:
They both charge
The one you listed is cheaper (even incl. shipping)
Not that flexible
I don't know what other USB devices you have to charge, meaning if they have different cables for different devices, I do.

the reason I mentioned that one was I could not find anyone for 5V
all are 12V
in your first post in this thread you mentioned you have all 5V ones
http://www.dealextreme.com/details.dx/sku.13522
i bought 1 of these. works great. has 3 inputs and 1 usb port.
My solution to the car charging problem has been a power inverter. You can charge your phone using your house charger, and plug in other stuff at the same time. The last one I bought even had a couple of USB ports so I can use a standard USB cord to charge various devices. Also handy for plugging in my laptop, dvd, tv, etc.

A car's battery is 12v. So when they say 12v, they are referring to input. It should then regulate that 12v to 5v (USB spec). If you are worried that this one does not have this regulator, spend a few extra dollars and get a better one.
A car charger should have a regulator anyway, because your car's alternator can output up to about 20v. For USB devices, it needs to be regulated to 5v, or damage may occur.

types of usb connectors
Hey guys, tell me please are there two types of USB connectors to TP ?
I mean the one is like a regular mini USB and the other is an asymmetric one ? Because i ordered ones a car charger from ebay and got the one with the mini USB connector although my TP has the second one.
This is the one i think of buying http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&item=250434240310&ssPageName=ADME:X:RTQ:US:1123
TP has a special usb head for multimedia etc, but for charging use, your item would be ok.

Old Motorola Car Charger
I use the car charger from my old Motorola Razr. It has a charging light and charges quickly, however, the Razr will not charge from the Fuze home charger...David.
It seems that there is an important issue about car chargers, which isn't mentioned in this thread. The HTC car charger is 2 ampere, where othere chargers (like the one I bought on Ebay) or only 0.5 ampere. This is problem when having heavy load on your Touch Pro. It then actually still drains battery while charging.
Since AT&T no longer supports the Tilt i can't buy an original car charger from them anymore. The one i have no longer works, and from what i've gathered across the intarwebz is that unless you have a factory original car charger or l33t soldering skills, you don't get to have a car charger anymore. Is this right?
Since i don't own a soldering gun, is there a car charger that will work guaranteed? I checked HTC's site and it looks like they are just selling cheap aftermarket generic car chargers.
ANy help would be appreciated.
Thanx Snow
i just got mine from seidio in a combo bundle, no problems for me
How long have you had yours Gelf? Mine worked great initially, then one day i noticed it wasn't charging at all.
Car Charger
I am using a car charger from a Blackberry. If fact, my wall chrager is also from Blackberry. Had them left over from the old days.
Never have any problems.
http://www.mobilefun.co.uk/product/4072.htm
I have one of these, it's a genuine one and charges as well as a wall charger.
My mini USB connector is knackered after I tried to re-set my phone by jamming the stylus in it, so now I have to wiggle it to get it to charge.
Any mini usb charger will work. depending on the volts it may take longer to charge. I sell them all day at Radio Shack and use it for my tilt. just a generic one will do
Don't go cheap on these -- I had a cheap one that fried a device.
I currently use this Belkin...
http://www.amazon.com/gp/product/B001FB578I
includes a 1-amp quick-charge port and a standard 500mAh port
Im lucky i have a USB port on my stereo and i just use a standard mini usb cable to charge my phone, otherwise i use any motorola USB charger and i have nvr had a problem with any of those.
There are threads around about car chargers for Kaiser - search is always good. The general opinion seems to be that non HTC chargers can be unreliable. I've tried a few that sometimes charged and sometimes didn't. Often they would charge for a few mnutes then stop. Rarely seem to charge with GPS running, they just don't seem able to supply the power needed. However I bought a 'genuine' HTC charger from ebay and it's been working great for months. They're still available for aound $AUS20. I think it's worth trying to find one that states 1 amp output from memory. In fact, think I'll buy another now just in case they disappear! Can't remember exactly who it came from though.

Yup yup. Go HTC if you want reliability. I had a 'Tesco Value' one that showed it was charging but I could never work out why my battery was dying. I found an app that logs the mA charge or discharge rate and that told it's own story; when the Kaiser is working hard - GPS, bluetooth and a couple of apps running it can be pulling well over 500mA. Spend the money, it's worth it.
I got a phillips car charger from Asda for £5. Has tips for most types of phone including mini-usb. Charges my kaiser fine.
Hi,
I always answer the same when I see this kind of demand: buy the official HTC one, it cost something like 10 euros in the EU (probably 10-15 $), and you'll have no problem (see a previous post here).
I had a cheap one, it was a no-go. ince then it's perfect.

Agreed. The official charger has worked very well for me. Got mine here. Mailed same day and Priority Mail. Have ordered a number of things from them and highly recommend.
I use a motorola v3x car charger
Thanks for the help with alternate ideas and places to look at for buying an official adapter. I'll look around.
I bought a generic one off of Amazon and that worked for about 3 days and then it stopped charging as well. I hope that i can find a solid alternative.
And for anyone who mentioned that i should use the search or off handedly implied that i did not search. You should really stop with that behaviour. It makes you sound like a pompous clown and doesn't add anything of value to this thread or to this site for that matter. For those that provided valuable input, thank you very much for your time and consideration.

Apologies if my comment sounded rude, it was simply meant to alert you to the fact that there are many threads on this topic that may help and you didn't mention that you have searched already. I know the search function on these large boards is less than efficient and can be frustrating. It's a good idea to mention that you've searched as many people don't bother. For starters, the following threads are related to this issue and have more info than this thread:

Personally I only reply to questions if I think I can help and because I've had so much help from others, not because I have nothing better to do.
all i have to say is, i'm SURE theres a charging circuit built in that will not allow it to charge at too high of a rate in mA's, the OEM one is fairly high (like 850 or 1a as some have said) although i've had fine luck using pretty much anything, i use a mini-usb cable attached to a computer to charge most of the time, the USB standard will allow a max of 500mAh, so it takes longer, but whatever, i have also used Mot. V3 chargers for a long time with fine luck, really the only one i have that doesnt work is my bluetooth headset charger, and its mini-usb but its rated for an output of 350mA!
I had similar problems with my Kaiser. For almost a year it would charge with car charger then it stopped. It would charge fine on AC and computer USB but not in the car.
If you look inside the USB port on the phone at the bottom are two little tabs/fingers. They need to be lifted up to make contact with the charger. I took a dental tool and slightly lifted them so they make better contact with charger plug.
Also make sure that the plastic inside the usb on the phone is not curved or bent as some of the pins will then not touch then. I straightend out the plastic tab inside the USB with a small screwdriver and then made sure that the little grounding legs were bent up a bit and bingo it works.
I use a Motorola charger as well in the car and it worked fine for Blackberry and other phones I checked so I knew the issue was in the phone.
Buying a new charger may not solve the problem if its in the phone. Thanks to those who posted their findings as after I searched I was able to peice together a few ideas that worked.
go to ur local office supply and get one of those cigarette usb chargers (mine is for an HP Ipaq I used to have) and use your data cable ... it works fine

hmm Scary!
Bought one of these guys to hardwire a charger in my car:
http://www.mountguys.com/product_p/mfx5v-b-micro.htm
On the charger is specifies 5V 1500mA output. Is that ok? I know it's more than stock, but I thought circuitry can step it down if needed.
Also, I'm thinking I want to hardwire to the always hot lead that goes to the radio memory function. Any chance of current problems? Don't think it will drain my battery if I leave it charging while shopping (or at the bar)
Thanks.
I'm curious why you chose to hardwire it, when the device can only pull 700mA, and these little wonders work perfectly.
Nice! Got one of these also... twice the ports and 5X the price:
http://www.amazon.com/Griffin-Powerjolt-Dual-Universal-Micro/dp/B0042B9U8Q/ref=pd_cp_e_2
Yours and mine above specify 1A... this one:
http://www.amazon.com/Charger-Samsu...96/ref=sr_1_15?ie=UTF8&qid=1318442293&sr=8-15
2.1 A.
I just wanted a cleaner look in a little sports car... the hardwire is going to come out the panel and go straight to a dock. But now I'm worried that 1500 mA could be troublesome?
It won't be troublesome, just useless.
I have a setup for my iPod that utilizes one of what I linked. I've got a USB+RCA-to-dock cable running into my center console, then into a port in there, to some empty space in front of it (under the trim, totally invisible) where my audio guys spliced a new line into the RCA jacks that came from the factory, and split off another power line. The charger's in there, cable connects to the ports... It's nice and clean.
this should be fine. the amperage rating on a charger just tells what it is capable of if requested. it is up to the phone itself to provide the requested amount of current. that is to say if this charger can provide 1500mA, but our phones can only use 750mA, your good. it is provided all the current it needs. now on the other hand, if you were charging some device that could use 2000mA(unheard of) this charger would provide all it could, the device would just charge slower.
the voltage is fine. most chargers are rated at 5v, and should be spot on as long as it is a decent brand from a trusted source. a knock off may be out of spec to what it is rated. that is where you could run in to trouble with frying a phone.
anyway, besides all that, this seems risky. not hardwiring a charger to your car, but leaving it there while you are shopping or in the bar. ever heard that an ounce of prevention is worth a pound of cure? id hate to come out of a bar to a broken window and no phone...
i never leave my phone unattended outside of my home.

I will be interested to see if they charge through the microUSB or via a magnetic charger as standard, and if they charge from MicroUSB, how much the magnetic charger would be

Does the Nexus 10 support wireless charging too? That's pretty cool if so. I think about now is the cue for IKEA and the like to start producing high-end tables which automatically charge anything on top of them. Then you can truly be wireless (well, the table would have to be plugged in, but the odds are you could hide the wire from sight). Since the table is powered, they might as well give it a backlit surface, too. Now that would be a table.
