On the back of Acer Aspire E15 laptop wrote input voltage is 19V and current is 3.42A. May I know can I use adapter with 19.5V 3.30A to power up and charge the laptop? What is the input voltage tolerance for the laptop ? What is the possible effect of using the 19.5V 3.30A adapter?

    These are both 65watt chargers that should work just fine with your system if the charger plugs are identical. In both cases, the voltage is carefully regulated down to be consistent with charging a nominal 15v lithium ion battery.  Jack E/NJ

    Depends on the adapter. Generally speaking the output range of adapters such as yours should be between ~19v to ~11v.  When plugged in to your particular laptop, the adapter communicates with the battery's internal control chip to detect appropriate battery charging voltage ~15v and adjusts and closely regulates its output voltage to this same ~15v. What this means, is that your adapters can also be used in other laptops whose battery input voltage requirements are different but in the same voltage output range as long as the jacks are the same.

    Thank you for clearing my doubt. May I also know the maximum and minimum input voltage that can be carefully regulated down to be consistent for using Acer Aspire E15?

    AC input voltage to the charger must be whatever the AC output voltage of your mains are. In the US, this is typically 110 VAC. DC input voltage to the laptop must be closely regulated to ~15VDC. Jack E/NJ

    Sorry I think my question is not clear. What I wish to know is the voltage range that can input to dc jack of laptop. Meaning how much is the laptop adaptor output voltage range?

    HI, I bought my ACer Aspire 5 in Brazil - 19V - 2.37A - I´m planning to take it to England - will it work there? Besides Brazil ranges from 110-220 - we do not have 240 - and I have already burnt a hair dryer in the UK. Are there adaptors that can be used?

    Thanks in advance

    Can someone help me please? I do not understand the language of volts & watts etc... so this is my issue. I have same, Aspire E 15, original charger was torn by dogs, got a universal charger with different charger points and then the black "box" on the charger has a button to shift to settings from 12,15,16,18,19,20,24. I don't know if that is volts or what but to what will I set it to charge my laptop without it exploding please?

    What brand and model number is your universal charger? Or where did you get it from? It doesn't sound like a automatic voltage sensing charger with the button to select voltage from 12-24v. Sounds more like a charger made for NiMH batteries, not lithium ion laptop batteries.  You risk frying the battery or mainboard.   In my opinion it's not worth the risk. Google your 'full model number' and 'charger' for an adapter that made for your system. Usually less than $20. Jack E/NJ
