After-market safety treatment of low cost products

There was a time when it was not possible to obtain a proper pure sine wave inverter (12 V DC -> 220 VAC 50 Hz) without shelling out hundreds of Euros or USD.

Today, with the massification of supply and demand, and with the sheer scale of the chinese industry producing these types of devices for consumer and industrial applications, prices necessarily went down.

Until recently I had a modified sine wave inverter, which given its limited compatibility with different types of loads, I have discarded (resold) and went looking for a cheap pure sine wave (which intuitively I expected to be much cheaper in current days).

Through Aliexpress, I found a 500 Watt/1000 Watt peak for 38 Euros (roughly the price I paid for the modified sine wave model years ago - and it was only rated to 250 Watts):

There is nothing like an Enterprise grade solution for a Consumer grade problem

In current times, there is an ever increasing separation between the consumer and physical storage media as a product: with the generalized increase of Internet availability and bandwidth along with massification of server side infrastructures to support storage and other services (e.g. from providers such as Dropbox, Google, Amazon, Microsoft), the user tends to replace the physical storage by the convenience of a cloud storage solution.
