Hi, can anyone help please with advice on what the maximum rating is for power input to the PW7015MC Dell Power Companion (12,000 mAh)?

Is there a limit to which chargers I can use?

The label gives an input rating of 19.5V 2.3A, but I don't know if that's the maximum rating of the chargers that can be used, or whether that's the maximum it will draw, but more powerful chargers can be used.

For example, I have a LA130PM121 PA-4E charger with my WD15, this is nearly 3 times the wattage of my laptop charger at 130W 19.5V 6.7A. Is a 130W charger safe to use in the PW7015MC?

Or if can't plug the PA-4E directly into the power companion, can I safely power the PW7015MC from the WD15? Or should I only use the lower power laptop charger, which is just 45W?

It's more about convenience than anything else - using a charger that's already available as part of the docking solution rather than taking the laptop charger in out of my bag every time, as I'm sure one time I'll forget it...
