Got one of these the last time they showed up here. I did a charge discharge on it and it comes up a bit short on the capacity. 70wh in, 56wh out. It's larger and heavier than other 20k battery banks that I've used if that matters to you.

Cuktech is a subsidiary of Xiaomi and one of the largest charging accessories brand from China.
Although, the English name they've chosen is a bit unfortunate.

This charger powerful enough to top up a laptop that takes a 65 W charger. Heavy well made. charges at fast charging standard on Samsung. Simple display is very useful.

this is a charger you give your wife to use, while you sit silently on the airplane with a dead battery and with your hands tucked under yourself. You peer over and can only slightly see all of the wonderful content she is enjoying.

Do you think that a company that doesn't even take the time to understand the impact of naming their product will give two Fs about their product itself? This is the way I look at all this chinesium that's dumped on our shores...
Its a large Chinese brand named after an electrical engineer who made some breakthroughs in charging tech.
It would be really easy to just print a different company name on the same chargers for export though........
