HTC MAX4G 1. The communicator included: charging that with closed with open contacts that - the current of 850 mA
2. The communicator off: charging with closed contacts - current 850 mA, charging with open contacts - Current 420 mA
3. Charge from a USB port - a current of about 420 mA
HTC HD, HD2, Diamond2, HTC Desire, HTC Evo 3d 1. Charge port or USB charger with open contacts 2 and 3 in a USB connector - current consumption of about 450 mA source
2. Charge charger with closed kontaktamii 2 and 3 (full-time charging) - current consumption of about 900 mA
Garmin-Asus M20 1. The charging from the charger 2 with open contacts, and a USB connector 3 - current consumption of about 500 mA source
2. Charge charger with closed kontaktamii 2 and 3 (full-time charging) - the consumption current of about 850 mA
Analogichno to get a normal charge
ASUS Pxxx, Samsung GT-I8000 and a number of other communicators need closed contacts 2 and 3 in the charger, or charging controller generally can not turn on.
In these full-charging device contacts 2 and 3 are closed.
HTC 7500 1. Charge port or USB charger with open contacts x and a USB connector GND - current consumption of about 450 mA source
2. Charge the battery charger with closed kontaktamii x and GND - current consumption 900 mA
Have
Glofish -s to charge the normal current is necessary to close the contacts x and GND in the mini-USB, otherwise the current seems to be only 100 mA
ACER beTouch E200 and apparently the rest of the series - the heirs Glofish
1. Charge port or USB charger with open contacts x and a USB connector GND - current consumption of about 450 mA source
2. Charge the battery charger with closed kontaktamii x and GND - current consumption of 900 mA. If further close the contacts 2 and 3 - the current limited to 450 mA (due to which I have not turned universal memory with closed x and GND, while 2 and 3)
Thus requirements to the charger (any - cars or network)
1. Voltage 5V (4.75 - 5,25V)
2. The current of at least 500 mA (
if not close contacts - but in this case, some devices do not receive charging).
If the contact is closed - you need to charge current of at least 900mA . Acquire Charger rated at 1A more it makes no sense - charge faster still will not
3. The most difficult thing - to find a charger with closed just those contacts that are needed for your device. I'm in their charging NO contacts or in the charger or cut mini / microUSB connector housing and has already brought up in it, glued cover
Photos - cable connector, drawing - block .
With its ASUS P525, HTC MAX 4G, Diamond2 and then HD2 using the converted network and car charger (1A, each with a built-in connector USB, pins 2 and 3 closed) - no problems using conventional sync cable, currents are measured to include the ammeter in the gap wire + 5V and closing / opening the contacts to the USB connector.
For HTC 7500 and then made the ACER separate cable (two-wire, only the power cord) in which a mini-USB and closed the contacts (initially were closed and the contacts 2 and 3 but for ACER is not suitable -prishlos open), chargers do the same (with the built-in USB and closed contacts 2 and 3), there are no problems. Garmin-Asus to use a conventional sync cable (it should be closed 2 and 3 contacts for him)
Posts about burnt chips charge controllers on the motherboard communicator met a lot of (mostly due to poor road zaryadok - even saw a photo of burned for this reason, salons vehicles themselves), so do the charger before using the check on the quality of installation, load capacity - the maximum load current , the output voltage range of load and without, the degree of heating under the maximum load. Especially true if you buy a cheap device manufacturer unknown, in reel stands with brand well-known brands are usually okay (but the price is not frail). Once selecting reliable chargers continue to change only the connecting cables or modify if necessary connectors.
