Review on DigitCont USB to 12V Power Cable for Dot Devices, 4mm x 1.7mm, USB Voltage Step Up Converter, Power Supply Adapter, 4ft, DC 5V to DC 12V Cable (Black) - 2021 Edition by Jason King

Excellent. Did exactly what I needed as promised. I have a 2 amp USB adapter in my cigarette lighter. When my phone is connected to a hotspot, I have an exho hotspot in my car. Fully functional and hands-free. I have a Revain bluetooth speaker as my 97 240 sx needs a new radio (+-200) for AM FM only which is great. Anna, I can take/use them on my boat. Take these items and get great sound.
