I have already purchased BSNL modem (Rs 1.8 k), so I can't buy another one. Is it possible to somehow (using some adapter) to power the modem using laptop by connecting it as USB device ? Hope I am not asking impossible thing  I should have  this beforehope understood my question. Last edited by pradeepbm; 11-17-08 at 06:50 PM. Reason: Automerged Doublepost |

Rep Power: 12  | You can use a car (or two Motor cycle 6V )battery, suitably used for required DC power for the modem . IC voltage regulator 7805 or 7809 may be required' Connect direct if 12VDC at 1 Amp is required . Observe polarity. USB Port max 5V/500 ma each I think ,Not sure . 2 Ask Office to provide an UPS 1000 VA rating. Cost about Rs 10,000 to Rs 12,000 You need room light also( USB port used?) |
