Product Description Dual USB Charger We carry the Blue Sea Systems 1016 dual USB charger. It’s the same charger used in our custom built boat switch panels.  We found it has a nice tight cap to prevent water intrusion from damaging it. Sports two USB charging ports, and requires 9 – 16V input, perfect for 12V systems. The 5V, USB charging output can support 2.1Adc total from both ports. It has one green LED that glows when power is supplied.  Install it easily with a 1 1/8″ hole saw and included mounting nut. It comes with the little bezel pictured, but most people just throw that thing away, and straight mount it… we think it looks much better without the bezel honestly, and unless you mess up and cut the hole too big, there’s really no reason for it. Remember, you can design this product into your own custom switch panel with our drag-and-drop E-Panel Builder.
