Best pure sine wave UPS for Mac Studio M4, unstable power

WHAT IS THE BEST UPS "pure wave" FOR A mac Studio M4 (2025) ?

My mac Studio M4 is under Tahoe 26.5.2

I'm currently in a mountainous region of Argentina. The electricity supply there is very unstable.

I could buy a UPS (240 volts pure sine wave) in Argentina at an exorbitant price, or in Santiago, Chile. I could also buy one (in Santiago) from Amazon in the USA and pay the customs duties.

But which one should I buy in terms of price/quality?

Best regards to all

Re: “… buy from Amazon US …”

FYI, single-phase 240 VAC UPSs are a fairly rare commodity here in the US where single-phase 120 VAC dominates.

As you’re making a non-trivial investment already …

One item you might also consider — in addition to the “usual” VA and Ah ratings — is if you should also invest in a low-battery auto-shutdown capability?

It’s a very nice feature to have if your system supports it, AND utility outage durations regularly exceed your Ah capacity AND your system (or “data writing-sensitive” peripherals) are often left running unattended.
