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 of charging controller on motherboard Communicator met a lot (mainly due to bad car charging - I even saw the photo of the car burntables for this reason), so the chargers themselves checked on the installation quality, the load capacity - the maximum load current , Output voltage range under load and without, heating degree at maximum load. Especially relevant if you acquire a cheap device of an unknown manufacturer, the charging with the brand of known brands is usually everything is in order (but also the price is not silent). Once by selecting reliable chargers, then changed only connecting cables or modified if you need connections.
