Revision guide states that charge carried by the electron is 1.6x10^-19 C

Shouldn't it be -1.6x10^-19C on an electron, and 1.6x10^-19C on a proton?

Yeah you're correct I think.

I thought electron was: -1.6x10^-19C which is what you put and also what you put for the proton was correct

What revision guide was it?

in textbooks and databooks elementary charge is afaik always given as +1.60E-19

and it's up to you to remember that electrons are -ve

can't speak for that particular book - in some cases it will not matter e.g. if calculating the *speed* of a particle after a certain amount of time in an electric field of a particular strength
