Decently priced for what it is. That's assuming it has power factor correction and doesn't throttle after overheating. Annoyingly has integral cable. Manual says it supports PPS but doesn't say if it supports 5A PPS for Samsung. I still think the Satechi 165W is a better form factor. Is on sale sometimes for $70 at Costco. More on reddit.com

I've been down the rabbit hole of what type of cells Anker is utilizing on their Prime Power Banks. Finally after over a year I found a video disassembling one. Anker uses Amprius 884669 cells. Not too certain, but they might also be silicon cathode cells which have good density, low internal resistance, good cycle life and low heat. If true, it would explain the amazing charging and discharging characteristics on their Prime batteries with charging base compatibility. Amprius doesn't publish data sheets for their batteries, but based on the few Chinese sites, their silicon cathode cells can get 500 cycles of high powered use (like regularly fast charging/discharging), or >1000 cycles of slower charging and discharging. Of course if you regularly charge to full and leave it overnight (like you would leaving it on the charging base), these cells still experience bad cycle life. Take this information with a grain of salt though, but I hope it's all true. More on reddit.com

I had the same question and my answer was going with the satechi 165. however in Amazon / Germany the are at about the same price point. Good resource is this channel https://youtu.be/OKIf2JOl87g?si=xR8QA9Uh2Vyr5XUU More on reddit.com
