Thats not the Adapter of the shield and its not class 2 or above so its not double insulated from what i know.
Also its not a low powered android box because it can reach ~25W at 110v
I think the PSU I linked to is for the Shield tablet not the console.
However I just found this : https://youtu.be/HPJzkdNkxvk?t=257 which shows the unboxing of a Shield Console. The time code I've linked to (4'17" in) shows a close up of the PSU. (It's 19V at 2.1A)
It clearly has the double insulated logo (two squares inside each other - http://www.double-insulated.com ) on the right hand side above the crossed-out waste bin and next to the little house logo. It has, like many adaptors of this kind these days, a slide in country-specific plug adaptor, which would allow a UK, EU, Aus etc. replacement plug-in adaptor to be used instead. It also clearly has only two metal contacts. There isn't an unconnected earth contact. A UK slide-in adaptor used to replace the US one would have a plastic earth pin. An EU adaptor would probably just be a Europlug 2-pin style one.
But still double-insulated doesnt prevent you from frying the device - it only prevents you from from getting shocked
Yes - but earthing doesn't prevent you from frying the device either. And you can't earth the device because it is double insulated and doesn't have an earth connection...
I thought the point you were making was that using a US to EU/UK/Aus type 2 pin adaptor would make you more susceptible to frying the device than using one with an earth pin, or using it in the US. Neither of these are the case. It is likely the device will be just as susceptible with a native EU/UK/Aus connector on the mains adaptor (as it is likely to be sold with in the UK/EU/Aus) as it would be through a decently designed plug converter.
Surge protection externally will protect the device from surges caused by the incoming power to your house or flat, or - I guess - a fault in your house or flat wiring. I think they are more common, along with domestic UPS solutions, in regions with poor quality mains supplies. Here in the UK we don't really have that many issues with power surges, and surge protection is seen as a 'sell it to the gullible' product, a bit like Monster HDMI cables.
You don't need surge protection more because you are using a 2pin converter. From your original post I thought you were suggesting that because it was an imported product using a 2 pin adaptor it was more likely to need surge protection.
I HAVE seen electrical equipment fried once in the past, when the electricity company messed up some work outside my dad's house. He was fully refunded for his Fax machine (it was the 80s...) and clock radio that both failed by the power company.
