I'm off to Glastonbury and would like to be able to charge my Magician while I'm there. I've got shed loads of 2300mAh NiMh batteries and four connected together gives pretty much bang on 5V (5.2V no load).
So if I just stuff that in the USB hole on the bottom of my Magican will it charge OK? I know that USB is only 500mA but the mains charger claims 1A. I think I can get away without a voltage regulator since the voltage is so close but I don't want it drawing too much current.
Any thoughts? Anyone tried this?
Cheers
Jamie

The instruction book tells me to attach the charging cradle to the A/C power source for charging the battery on my 2020. However, it 'appears' to charge without the A/C adapter. Is this an erroneous reading ? I mean, why attach the A/C adaptor unneccesarily ?
Thanks in advance

I think one trickle charges and the other rapid charges, I am not sure of this but making an educated guess.
it can charge using the 5volt 500mA that usb give
but not all pc's can give those 5volts from usb when they are turned off
plus i think it charge slower when it can only get 500mA
I am trying to find out what the correct, original charger is for the wizard.
If you have a wizard, can you please look at your home wall charger / ac adapter and tell me what the specs are? Is it 500mA, 800mA, 1A, something else? It should say directly on the charger somewhere.
Also, have you ever had any problems charging the phone with it. There is a problem with the travel chargers (500mA) charging a wizard if the battery is completely empty - it has trouble starting the charge (charges fine if it didn't die completely). So - if your phone battery completely dies because you did not charge it at night or something, can your charger get it charging and running again without any issues?
That's it! Just trying to find what the original charger is so I can order one like it. I have found 800mA chargers easily but I was thinking the original was 1A instead. Not sure though...
Thanks!
Only 1.00 amp charger is capable to charge a completely discharged (dead) battery,so get a 1A wall charger,you won't regret.Every Wizard device is supplied originally with a 1A charger,so thats what I have,never had any charging problem,even if sometimes gets lower than the required retention charge,it gets the battery charged.
That's what I thought...I'm just having the toughest time finding those online...It seems nobody has an original charger or even one with similar specs...They are all too weak...the 1A chargers I have found have been 5.5V and not 5V.
Any ideas on where to get an original? It seems like 5V 1A USB charger would not be so hard to find but they are all too weak or don't list the specs (in which case they may not be the right one). Perhaps there is a manufacture part number on your charger? If so, maybe I can do a search for that part number and find it.

Well,I can give you charger details which I'm using ,I don't know if its available online,but there's no harm in trying,You can try e-bay online,here they are :-
DELTA ELECTRONICS INC
AC/DC Adapter MA0614
INPUT : 100-240-200mA 50-60Hz
OUTPUT : 5V...1000A
Good luck !
Long story, but I bought a used Fascinate without the stock charger.
Could someone install, or hopefully already have, the "Battery monitor Widget". Then plug their Fascinate into the stock AC charger or stock car charger (NOT the USB on a PC), and let me know what the usage (ma) reading is on the widget.
More of the story. Basically, I know that at least on older HTC devices they would pull more charge/operating power from a non-USB connection. Actual USB is limited to 500ma load, so they had a system that kept the current low on USB and bumped it up for non-USB. All of the non-stock cables that I have show a very low charge rate on the Fascinate. It in fact runs the battery dead while on charge and I use the phone with GPS software.
i can tell you the factory charger is putting out 5v at .7a(700ma).

Thanks, it is good to know that they stick with 5V. But it just means that it can put out up to 700ma. I suspect it is using about half of that.
If you can cut open the wires and insert and ammeter in series, that is what I need to know.
edit: nvm ...
Found it. I have been searching for this for a couple of weeks and just now stumbled on the right search keywords.
For anyone that wants to know.
The Fascinate appears to pull about 350ma from the 5 volt supply normally. But, if you short out the USB D+ and D- lines in the charge connector, the charge current goes up to about 600ma.
That will help me not have a dead battery when using the GPS.
Oh, as an added bonus, you don't get the USB / Debug notification.
I have a MT4G as well as the typical HTC charger from it's package.
When I charge the phone using that HTC charger, it charges very quickly, obviously in fast charge mode.
My issue is that I need to be able to charge my MT4G when I'm not around an outlet, so I put together a system to give me 5V from an RC plane lipo battery, which can be pumped into the USB port on the phone.
I can charge normally off this, but I can't seem to get the phone to fast charge, no matter what I do.
I probed the HTC charger, and it appears to pull D+/D- up to 3.3V, which is exactly what I am doing on my charger.
If you probe my charger and the HTC charger, they appear totally identical. 5V coming out USB Vcc, 3.3V out of D+ and D-. The phone says it is in "AC charging mode" with both chargers, however it only draws 130mA from my charger, not nearly enough to _actually_ be fast charging.
Any ideas on how to force it to really fast charge?
Short D+ and D-. Don't pull them up.

Also tried that, also tried shorting them with a low value (70R) resistor. Still says AC mode, but still doesn't fast charge.
Hmm..

This also says to short the 2 data pins and nothing more.
If you find out that there's something else needed - please share.
At home I have an iPhone 5 charger and a Blackberry Bold 9900 Charger along with a Cooler Master Battery Bank. The out put on the battery bank claimed 5 Volts 2.1 Amps but when hooked up to my HTC One it showed USB Charging. I hooked it up via my iPhone 5 charger which has an output of 5 Volts and 1A and also got USB Charging but when I hooked it up via Blackberry Charger with an output of 5V / 750 mA I got Charging (AC) on my HTC One. Looks like it won't accept any higher power input than what it needs for faster charging.
Picture posted is via Blackberry Charger.
Here is a picture via Cooler Master Battery Bank showing charging (USB)
The maximum current is drawn when the battery is empty. The first phase of charging is constant current, where it will draw up to 1A from AC and 500ma from USB, then moves to constant voltage, where the current will drop off. Your battery is probably too charged to be drawing max current.
HTC phones switch to AC charging when the data pins on the USB are shorted, otherwise it's USB charging.

I need to double check which USB cable I had used. At work now but just saw that the USB cable I had at work was the Blackberry USB Cable and when I hooked that one up with my new HTC ONE I got AC Charging on my HTC ONE. A sales person had told me that the USB cable can make a difference at times. Will try messin around with a few wires along with my Cooler Master Battery Bank to see if the results change.

I find that the charger it came with charges it fastest. The other chargers I have used are my neuxs 4 and gs4.
The phone is looking for a 'short' across the two data wires, I believe. The HTC chargers have this so that the phone knows it's not a USB port that isn't able to deliver the current. I'm surprised the blackberry charger fooled the phone to think it's AC.
