That .01 Amps is indeed miniscule and will not make a difference. Just be careful that you purchase a genuine Dell adapter. The problem with a non-Dell adapter is that it may not be recognized by the system and will not charge the battery. I believe this adapter is a Dell OEM adapter for example.
I have a Dell G5 SE 5505 and I'm trying to replace the charger, I've found chargers with 240 Watts and 19.5 Volts but my laptop says it has an input of 12.31 Amps while everything I can find says it outputs 12.3 Amps. It's a pretty miniscule difference and the Wattage is 240 in both cases, but just in case, will the difference be an issue (if their even is a difference and it's not just rounding)? The charger model I have right now is DA240PM190 and the one I'm thinking of getting is GA240PE1-00
