This doesn’t apply to your MacBook, but with my desktop computers, I use an (APC) UPS due to power fluctuations. Once in a while I hear it kick in for a second or two, not often but enough….
A UPS is made as cheaply as possible. Even noise can cause it to click to battery. If it was clicking due to unstable power, then incandescent bulbs were also reporting unstable power.
For example, voltage can vary so much that an incandescent light bulb dims to 50% intensity or doubles intensity. Even voltage variations that large are ideal for all electronics. Internal DC voltages do not vary even 0.2 volts. Why would anyone need a magic box to address voltage variations that are already made irrelevant by what is inside all electronics?
If voltages are varying that much, then a UPS is needed on less robust appliances: furnace, dishwasher, washing machine, and central air.
Easy is to manipulate naive consumers ... who do not always demand relevant numbers with every recommendation. That promotes sales of magic boxes (UPS or plug-in protectors) that do nothing useful.
And yes, that surge protector recommendation is just as bogus once numbers are included in the recommendation. It also was recommended subjectively. First indication of disinformation - a subjective recommendation.
UPS is temporary and 'dirty' power so that unsaved data can be saved. So 'dirty' that they quietly recommend not powering strip protectors or motorized appliances from a UPS. Electronics are so more robust. So 'dirty' UPS power is perfectly good. But only to protect unsaved data. UPS does nothing to protect saved data or hardware. Superior protection inside more robust electronics also makes 'dirty' UPS power irrelevant.
Surge protector has a let-through voltage numbers: typically 330 volts. That means it does absolutely nothing until 120 volts is well above 330 volts. If a surge protector is needed on any one appliance, is it required for ALL appliances.
A UPS is for voltages falling to zero. How is a voltage approaching or exceeding 1000 volts also a voltage failing to zero. Two completely different and unrelated anomalies addressed by two completely different and unrelated solutions.
Power in Europe is equally unstable (or stable) as that in North America. But then someone recommended a Belkin. Learn what others learned the hard way. Including
Sarah Q, Average Joe, and sandra r.
It caught on fire and burned my carpet, but it didn't burn the whole house down since I was sitting right next to it.
All plug-in protectors are that 'near zero' protection. Anyone can learn reality by simply demanding numbers. How does its puny thousand joules 'block' or 'absorb' a surge that can be
hundreds of thousands of joules?
Every honest recommend also includes numbers such as these. Subjective is a first indication that one is lying or is easily deceived.
Other solutions can solve these threats. Solutions that come from other companies known for integrity. But the OP was not asking for that. Exposed is disinformation behind recommendations that are irrelevant to the OP.
