pathfinder662 Posted March 26, 2009 Share Posted March 26, 2009 Hey guys, I have a g1 and it uses a mini usb charger. I was wondering. Do all chargers with the mini usb plug output the same voltage? My gps unit uses a miniusb and so does my old motorola phone. I am able to connect all 3 devices to my computer and they will charge, but is it safe to mix and match chargers?

dr0p Posted March 26, 2009 Share Posted March 26, 2009 I mix and match all the time and have yet to have any problems, and I can't see why there would ever be a problem... Quote Link to comment Share on other sites More sharing options...

You should be ok, emphasis on should. Most USB devices require 5 volts for power, and most USB ports put out, you guessed it, 5 volts. I would be cautious though and stick with only the charging cable that the phone manufacturer provided. Some USB devices may only require 3 volts, and their chargers will have a resistor built into them that reduces the voltage to that, and if you provide too much voltage you may damage your phone. So my 2 cents, be careful! Quote Link to comment Share on other sites More sharing options...
rtc443 Posted March 26, 2009 Share Posted March 26, 2009 Usually if its the same connector then "usually" you can charge the device. As janders223 said usb ports put out 5 volts and i believe 500mA. the mini usb is a real common plug usb hdd, razor phone etc. If its a really $$$ device then i would just go on ebay and find the correct charger for $5 or so, beats frying your gps, phone or whatever. Most of the time you can also look at the ratings on the wall charger. I once had a phone and two chargers. One charger was rated for 5v @ 500mA and the other 9v @ 750mA but they both connected to the phone just fine....needless to say i diffidently smelt some burning plastic on that one, and the phone go real hot. Hope everything works out!! Quote Link to comment Share on other sites More sharing options...
Mat Posted March 26, 2009 Share Posted March 26, 2009 USB is a standard, its 5v at up to 500ma. Nothing else. If you get ANY voltage other than 5vdc from a USB port, then it's faulty. Therefore if a device can charge from the same port it uses for data transfer, then it wil be safe to connect this to any usb port with any cable.

vector Posted March 30, 2009 Share Posted March 30, 2009 i have a couple htc phones the htc touch diamond and the htc touch HD i usually use my old motorola chargers for them because the htc chargers that came with them has this stupid euro plug and i have to use the american adapter and it sticks out from the wall and falls out of the socket if you dont have it in just right, so i would say no, you shouldnt have any problems charging your htc g1 with a blackberry, moto, or any other standard usb phone charger. i havent encountered any problems yet.

VaKo Posted March 30, 2009 Share Posted March 30, 2009 Just charge from a computer instead? Far more simple. Or get one of these: http://www.amazon.co.uk/Sony-AC-USB-power-...r/dp/B000FNUPRK Quote Link to comment Share on other sites More sharing options...
