One year ago, I bought this USB connector to link phone to PC, and to power bank.

I should have bought 5.

This is the only brand, including Samsung OEM, that has not cracked, or become loose in the phone port.

I have searched at a few stores, including where I think I first purchased this one. However, either I forget where I bought it, or it is no longer being stocked.

This was very low priced, and the variety I now see on pegs in stores is boxed, and high cost. But inferior IMHO.

I would like to buy 5 one meter long connectors.

The distinguishing feature on these connectors is the "B" mark.

I saw on Amazon that this mark seems to be that of RuiLing company.

Judging by my success with the one I purchased last year in Chiang Mai, I would say the quality is outstanding.

I think these are only offered in the color black.

1. I do not know if what looks like a B might be a trademark for RuiLing. Maybe it signifies something else.

2. However, it seems the connectors I am looking for are produced by this supplier.

This is a clearer photo, but I am seeking the micro USB to standard USB cable.
