Review on 🔌 StarTech.com 3ft USB to RS232 DB9 Serial Adapter Cable - High-speed 1 Mbps Converter - M/M USB to VGA Adapter (ICUSB232SM3), Black - Enhanced Connectivity Solution by Tim Lea

Bought this cable from cmple seller. I connected it to my Samsung Galaxy S3 and the battery either stayed the same or even decreased. Tried in different ports and in the car - same result. This article has gone to the trash. I spent $8 on a wired USB car charger from another well known company that I found at the Burlington Coat Factory (of all places) and it worked great. Spend a little more to get quality or not, you will come back to this site in a month after buying another item.
