    Charging from notebook is very slow with only 500ma of current and you have to keep your SGT turned off, but if you use an double headed usb cable like the ones that come with usb hdd`s and dvd roms, you will get 1000mah as it is getting power from two usb ports.

    I have found an adaptor that will turn the male mini usb into a female standard usb for only $1.61 each, so you can plug your SGT into, it would be nice if we could find a single cable instead of the lash-up

    I have not tried this yet, if anybody can suggest a better way to charge the SGT from a notebook please let us know.

    Thanks

    John.

    Nice discovery, Tinderbox.

    I've moved it to the Galaxy Tab Tips and Tricks sub-forum.

    I've just got a Galaxy Tab and I don't seem to be able to charge via the PC, are you sure this works?

    As i said in post one, I have not tried it yet, I have ordered one of the $1.61 adaptors, I should have it in 10-15 days, slow boat from Hong-Kong :( , then i will update this thread.

    I have heard that it will charge with one usb socket , but the tab has to be turned off before it will charge.

    A usb port is only 5v at 500mah , when the Samsung USB charger is 5v at 2000mah, four times at powerful.

    John.

    Just tried with the Tab switched off and it did start charging from the PC. So it does need to be switched off to charge this way.

    Weird.

    Wonder why Samsung did this? I find this very odd.

    The TAB has an 4000mah battery, it should take around 8-10hrs for a full charge from a notebook usb port at 500mah, but the notebook needs to be on, not in standby, unless it has an special usb port that stays powered when the notebook is turned off, or in standby , the special port normal has an lightning bolt icon on it, and it need to be enebled from the notebook bios, or an application in windows.

    I just bought a Samsung galaxy mini for my daughter (in the czech republic) and we are going to the States on holiday...how can i charge it? it seems i can charge from my laptop if i turn off the tab, but i don't know what a tab is...also does it matter if its 220 or 110 if i plug it into the wall?

    thanks
