I can understand why Anker isn’t making a locally serviceable unit, making a “black box” with some high voltages kept within, for safety.
But it means you’re utterly reliant on local stocks and vastly complex global supply chain to keep working.
Power outages are more common when we have major disruptions. Major disruptions impacts everything including warranty replacement, shipping, etc. Lots of random events, like a pandemic, or a Icelandic volcano, or a boat stuck in the Sueze canal, all interrupt supply chains.
I’d encourage the Anker engineers to focus on modular self-service. Anker’s profits would increase.
If Anker could demonstrate, say, 30% of the cells can die but the unit still functions, albeit at a lower peak Watts and reduced Wh, or they can demonstrate you can hot-swap the PSU replacement (even if a screwdriver required), and a much smaller replacement is shipped, it can bolster the Anker green credentials.
I solve the problem with multiple Powercore, and having a generally fault-tolerant set of appliances (USB evaporative coolers instead of air conditioning, a fully packed freezer, a packed fridge with water, flashlights, Eufy motion-sensing battery lights, etc) but if Anker could punch harder the upper limits of both scale and modular reliability, it would stand out better in the marketplace, sell more.
