P50

Pretty sure the Anker was best in class when it was released. Iniu P55 The p50 is even lighter but has a bit smaller useable capacity. More expensive, a bit slower input as well.

Wh is more important. I have the iniu p50 and it has lower efficiency and Wh than the anker. I saw a baseus one with a built in cable and similar size to the p50. Cant remember the specific model

Mind to tell me more ? There are actually a new product: INIU Pocket Rocket P50 https://eu-main.iniushop.com/products/new-colorful-iniu-carry-p50-e1-power-bank-45w-smallest-10000mah 160 gr x2 would bring at 320 gr which is same at 1x 20000mah. But I get it to have 2 separate small powerbank, but why

No most good 10k powerbanks with <20W input don't throttle early. They usually throttle at around 80% but this is inherent to Li-ion batteries physical limitations and cannot be avoided. See : https://batteryuniversity.com/article/bu-409-charging-lithium-ion When you look at the charging profile of

Hm yes you're right, I never realized the Nitecore throttled that badly (and even with that it's known to get hot during charge...). The Veger actually throttles later (2h vs 1h40 for the iniu p50) but over 2h the 6W input difference (15W vs 21W) means you need an additional 48min at 15W to push the
