Question Replacement Power Adapter compatible with 'Acer Switch One 10' tablet ?

[ally0007]

Hi. I cannot find an original power adapter for my Acer Switch One 10 (SW1-011) tablet. The original power adapter specs were: 5V, 15W, Max: 3 Amps.
I found an adjustable power adapter that can supply 5V and up to 3A. It is available in a 24W version and a 36W version. Which one will suit? Does it matter that the Wattage is so high?
Thank you!
