Review on Belker Universal Variable Replacement Connector by Sean Purnomo

I bought these adapters to use with my power station when camping. Very happy with the quality of the adapters and cables. I have a NextBook PC that uses 5VDC at 2A for power. I connected the appropriate adapter to the cable and checked the polarity. Hot or 5V is in the plug and ground is outside. After confirming correct polarity, I plugged the cable into my power station's USB port and was able to charge my PC's battery. The kit also includes several adapters that work with my other 5V DC devices. This reduces the number of cables I have to bring with me. I recommend this product and plan to buy their cable that allows you to reverse polarity.
