Another idea: UGUMO 2022 ECG PPG Smart watch men Heart Rate Blood Pressure Monitor Smart Bracelet For € 59,52 (inc VAT) you get quite a package.

And these can measure blood sugar level (in addition to all above) https://s.click.aliexpress.com/e/_DEXljDN

I love technology...

My next smart bracelet experiment: Smart Watch E600 It "should" monitor body temperature, heart rate, ECG, blood glucose, blood pressure, sleep. And can control mobile phone cameras.

So far, I learned, that GPS tracker should not be in the fitness bracelet - it's way off, eats battery, and, most likely, you will have a phone with you. Still, I like my Huawei fitband (https://www.likera.com/forum/mybb/Thread-Various-useful-things-on-Ali-eBay-whatever?pid=59323#pid59323)

And this one is a disaster: https://www.likera.com/forum/mybb/Thread-Various-useful-things-on-Ali-eBay-whatever?pid=63783#pid63783

Don't buy this one!!!! The blood sugar level meter is fake! It shows exactly the same graph every day, even if you don't eat at all! Body temperature meter shows the body temp even if the band is taken off. Sleep meter stops working after the first wake up. Oxygenation meter and lorenz' spread work only from 00:00 to 07:00. Trying to get my money back...

Obviously, I'm behind the Ali-progress. I've just learned about USB-C to DC converter cables and adapters! The cable triggers the latest USB-C power supplies, so they switch to 12/19/20 volts. So you can use a USB-C power supply to power up or charge lots of various non-USB devices! From soldering irons to laptops without USB charging capability!

This USB tester looks interesting. And its functionalities can be extended with modules.

Please let me know if there is anything more functional.

These have been around for years.
I remember seeing them in the late 60s

Weird, never noticed them in EU.
