Powershell to list All Activated Features in All Site Collections 2010/2013

Question

Need a powershell script to list all activated features, for all site collections/webs and to output to a csv, per Site Collection and to work on both 2010/2013.

Have seen things like this for a single SC but need it to re-iterate through ALL SCs in a Web App:

#------ Include the SharePoint cmdlets
Add-PsSnapin Microsoft.SharePoint.PowerShell
    $SP_SiteCollection = "https://SPWebApp"

Get-SPSite $SP_SiteCollection | % {

$results = @()

Get-SPFeature -Site $_ -Limit All | % {

$feature = $_; 
    $featuresDefn = (Get-SPFarm).FeatureDefinitions[$_.ID]; 
    $cc = [System.Globalization.CultureInfo]::CurrentCulture;

    $obj = New-Object PSObject;
    $obj | Add-Member NoteProperty  Title  $($featuresDefn.GetTitle($cc));
    $obj | Add-Member NoteProperty  Hidden $($feature.Hidden);

    $results += $obj;
}
$results | FT -auto;
}

Any suggestions?

Here you go, mister:

Add-PsSnapin Microsoft.SharePoint.PowerShell
    $webapp = "http://webapplication"

$results = @()

$webapp | Get-SPSite -Limit All | % {
    $siteCol = $_.RootWeb.Url
    Get-SPFeature -Site $_ | % {
        $feature = $_; 
        $obj = New-Object PSObject;
        $obj | Add-Member NoteProperty Title $($feature.DisplayName);
        $obj | Add-Member NoteProperty Hidden $($feature.Hidden);
        $obj | Add-Member NoteProperty Url $($siteCol);
        $obj | Add-Member NoteProperty Type "Site Feature";

        $results += $obj;
    }

    $_.AllWebs | % {
         $web = $_.Url
         Get-SPFeature -Web  $_ -Limit All | % {
            $feature = $_; 
            $obj = New-Object PSObject;
            $obj | Add-Member NoteProperty Title $($feature.DisplayName);
            $obj | Add-Member NoteProperty Hidden $($feature.Hidden);
            $obj | Add-Member NoteProperty Url $($web);
            $obj | Add-Member NoteProperty Type "Web Feature";

            $results += $obj;
        }
    }
}

$results | export-csv -path E:\Powershell\features.csv -NoTypeInformation

Refactor as appropriate :)

Edit: Updated the script to include Site/Web Url with every feature.
