 If the label only shows output in volts and amps we can use Ohm's law to calculate watts. ​ In this case, 19v x 4.62A = 87.78W, which is in line with the 90W number on the label. ​ If the label only shows output in volts and amps we can use Ohm's law to calculate watts. ​ In this case, 19v x 4.62A = 87.78W, which is in line with the 90W number on the label. ​

 +Checking email on a phone will use much less power than doing the same thing on a laptop. ​ Obviously, long replies are easier to type with a real keyboard. ​ You may find that a tablet with [[https://​amzn.to/​2ZY4TOC|a bluetooth keyboard]] works well enough to leave the laptop in the bag sometimes.
