Background

Heregulin-β also known as neuregulin-1 (NRG-1) is a member of the epidermal growth factor (EGF) family of growth factors and acts as a ligand for ErbB family receptor tyrosine kinases. And NRG1 isoforms can signal in a paracrine, autocrine, or juxtacrine manner, playing a fundamental role during the development of the peripheral nervous system and during the process of nerve repair, suggesting that the treatment with NRG1 could improve functional outcome following injury. The NRG1 receptors are membrane-spanning receptor tyrosin kinases of the ErbB family (ErbB1–4), of which the EGF receptor (ErbB1) is the most prominent representative.

Very slow, but good quality
Color: 2White
It works as expected, but my phone says that it is a slow charger even when plugged in my fast charger brick. False advertising. Really wish it charged a little faster

Slow As a Turtle
Color: 2White
Super slow charging. After 10 minutes, my phone only charged 3%. I plugged my original charging cord into the same 65W charging block and after 2 minutes, it had charged nearly 10%.
