I'll concede the A1289 has better in/out max at 140W (vs 100W on the A1695), and if charging a beefy laptop super fast is your primary use, then the A1289 is superior. I rarely am in a situation where the difference between 100W and 140W charge/recharge will make a difference, but if you're a high-power user, that difference is significant.
As someone who has both power banks:
- When I'm out and about for outings, evenings, and travel, and my primary devices are tablets and phones, I prefer the slimmer form factor and travel-friendly, built-in cables of the A1695.
- When I'm going from office to office and I know I have a stable desk to work on, I'll more likely be using a laptop, and have less concerns about bending the connectors on a plugged-in USB-C cable, then the A1289 makes more sense.
These typically only have about 500 cycles. If the previous owner already used 250 cycles, then you're basically buying half of what you would get with a brand new one.
It's kind of like gambling. You might get one that's almost new, or you might end up with something beat up or already halfway through its lifespan.
Not all refurbished products contain components with a finite cycle life, but batteries absolutely do. In small devices like this, particularly those operating at very high charge and discharge rates, degradation accelerates due to thermal stress and electrochemical wear. These batteries get hot during use, which further accelerates degradation. Capacity loss and increased internal resistance are not hypothetical. They are expected outcomes under these conditions. You also do not know how the refurbished units were used by their previous owners.
This is not just opinion. It is basic battery physics.

If you genuinely need to dump and feed power that fast, go for it. But with heat loss is not 2:1 and it literally burns to touch. I know, I have both.
