I loved this little power bank from the moment I got it. It’s compact and, quite often, I could just leave it on the bottom of my iPhone without really noticing it was there. It fit right into my minimalist, tiny purse and provided exactly enough charge to make sure my aging iPhone could get through a day out and about. Several strangers commented on how neat a solution it seemed to be and i think that’s one of the hallmarks of a good tech choice. I put it through very heavy usage, charging my iPhone overnight through the power bank, because lightning cables really aren’t convenient (I expect that isn’t recommended usage).
BUT
I was disappointed to find it had stopped working after 18 months. I found an article suggesting that power banks don’t last more than 1.5-3.5 years, so it seems to have enough durability to land within the expected range but I still find that 17+ pounds/1.5 years is an expensive “tax” to have to pay to keep a relatively modern (iPhone 12) smartphone charged for 8-10 hours without constant use. I’m now less mobile and have bought more lightning cables (which also deteriorate over time) to charge at home. I will buy another power bank in due course.
