I think you really need to separate the brands because the power banks are still the best.
People think that China is USA 2.0. It's not. It's a communist state with a single ruling party with unilateral control over every aspect of the country. They have capitalistic facets because communism doesn't work on it's own, but trust that the authority system is totalitarian, and if they want spyware in your product while you lie about it, there will be spyware in your product and you will lie about it.
It's interesting to see the non-response from governments over it so far; though there was recently rumours of an MoD ban on Chinese EVs but that seems to have been shot down[2] so far.

With the kind of infrastructure that holds Chinese technology in the west, they could shut down entire power grids, bring roads to a stand still, shut down entire countries worth of networking, cellular networks and worse. This is leaving out the surveillance and data collection potential as it's not the topic at hand.
To be clear, my issue isn't with China specifically, but as a westerner, they're not a friendly nation (to mine).
The same of course applies the other way around, and I can imagine a scenario of other citizens sitting in their respective nation having this same conversation about western technology.
China seems very much like a more straightforward and predictable trading partner.
Whether or not that's likely is another story, but it's possibly a non-zero chance and handing over control of critical infrastructure should be a concern.
