Living in developing countries taught me to never plugin expensive computers without a surge protector UPS.
Commercial uses layered surge protectors (Type I, II, and III), which is also recommended for other users but rarely followed.
In surge prone areas, at a minimum I would have good quality whole-house surge protector (eg Siemens 140 or Eaton 108), and a good quality surge protector strip for any computer/TV/phone charger.
I also put surge protectors in front of expensive white goods like the fridge, washer/dryer, dishwasher, and garage door opener. Besides being costly to replace these can contain "sparky" motors and this provides protection in the other direction too. Over time smaller surges can degrade the main surge protector for your computer.
Nothing (reasonable) can protect against direct lightning strikes, but for anything less it should provide decent protection.
Are you in an area with a bad electrical grid or something? In 40+ years I've never had a single device get fried from a surge/storm. My "surge protector" power strips are from the 90s and probably don't even work.
Not only should you get rid of them, they are a fire hazard.
Also, do not accidentally plug surge protectors into each other, metal oxide varistors can star fires _without_ meaningful surge conditions when you do so.
I prefer to buy products without MOVs entirely due to the risk, with the exception of one, Tripp Lite Isobars; but I prefer to use series mode protectors such as Brickwall or SurgeX.
This. Same timeframe and I've lived through both lots of lightning storms and in areas with lots of power failures. Some of them intermittent and essentially caused by transformers blowing up. Like earlier this winter, we had multiple storms where you'd hear a transformer blow up, in many cases even seeing the sky light up as well from it, power going out, couple seconds, power coming back, next transformer blowing out, rinse, repeat.
On the other hand I've read about plenty of stories of the "cheap" UPSs you'd usually buy as a consumer (not to name any brands coz I've never had any) actually causing such issues in the first place. Without any actual surges from the grid.
That said, being totally not superstitious (for real, but someone's gonna "kill me" if they find out I wrote this and something dies from a surge...), now I guess I need to knock on wood like seventeen times ...
I do use surge protectors when we're on generator power temporarily.

When I lived in Costa Rica, I lost three surge protectors in a year to power surges. During one such power surge, I didn't notice that the red light indicating surge protection was already out, and a power surge fried my (knockoff) Macbook power adapter, leaving me without a way to work for a day.
Not too bad, just rural. We used to lose stuff every 10 years or so.
One day The Big One came along and fried nearly everything. "Once burned, twice shy."
Hopefully someone can learn from my mistake and not have to do it post-mortem.
If your close neighbours have surge protectors then you benefit little from installing your own.

Belkin make a number of surge protectors which offer a connected equipment warranty in the UK. Admittedly: financial protection, not data protection, but I felt it was worthwhile for the peace of mind.

>Admittedly: financial protection, not data protection
You should have data backups regardless, because there are plenty of ways to lose data that don't involve power surges.
Have they ever paid out on one of those, or is it like CAs who offer liability protection for their certificates carefully set up in such a way that they never have to pay out.
>In surge prone areas
What areas are surge prone?
The California bay area, at least all the sides of it I’ve lived on. We currently have a whole house battery, whole house surge protector, a second surge protector, and a UPS between the router/nas/etc and PG&E.
It’s not good enough. At least the power stays on once the grid stops bouncing (or once I manage to log into the rebooting battery gateway computer to have it flip the “off grid” breaker, or go outside and flip the manual one by the meter).

Open aerial wiring can shortcircuit two phases, bringing a low impedance surge that can damage most electric and electronic equipment.
Areas with lots of thunderstorms. Also more rural areas with long power lines with few taps off for customers — the long runs are both exposed to many nearby strikes and accept induction well, and the few customers are fewer power sinks to dissipate the spike. So, you're more likely to get hit, and hit harder.

Lightning can mess you up in every country lol. Had to replace a PSU because of that, thankfully it was just that and minor damage to GPU.
Lightning damage is mostly an issue if the last-mile power lines are above ground. In my experience, power surges in urban areas with a decent grid are so rare that people generally don't bother protecting their devices.
I have lived in the DC metro area inside the beltway or in Sillicon Valley my entire adult life and have only had above ground power wiring. Despite tree ordnances and wind storms and a grid so aged if we see lightning we lose power.

So 99.99999% of the world.

Where I live it's not an issue.
Honestly even in "developed countries" it's not worth blindly trusting that the power in your house/building is clean. It's cheap and easy enough to just put any expensive hardware on a UPS rather than speculating what's going on behind the walls.
Eh, if these surges are rare enough, then you are statistical better off just risking your 'expensive' hardware to a one in a trillion possibility rather than spending money on gear you don't need.
Do you live in a bunker to protect against artillery shells?
I work on embedded systems. I can often see whether my A/C or other appliances are running on my oscilloscope signals. They often affect the output of USB power supplies.
Doesn't even sound like a developed country to me. Is that the US or something?
Do you still need a UPS if you have one of those household (Powerwall style) battery packs? Also Apple switched mode power supplies are pretty well built.
But then again there's horror stories like

My understanding is that home batteries are not UPSes, they don't go through the battery. They have a switch between power company, solar, or battery. I think that means would be exposed to surge from power company.
You can install a whole house surge protector. Those go in the panel and would protect from different sources.
Yes. The power walls are like cheap UPS topology. You could still get whacked with a transient from the grid before the ATS decides to island the house.
Depends on how they are configured, I think in some regions (where power outages are very rare), they are wired to sync up with external network, and without external network they shut down as well.
