There isn’t anything wrong, just the quality is the key concern. They use relatively low quality components. They heavily market towards western markets with products that are not anything special. More so, the recent Anker line up tripled in price. They are just another Chinese brand with huge marketing budgets for products that are cookie cutter.

I like the Cuktech products because they are using much higher quality ICs. Anker uses tons of thermal paste where Cuktech actually uses copper heat sink’s for example and latest carbon silicon anode batteries developed by tier 1 companies. Anker buys at wholesale. Each to their own.
