Product Description Blue Sea Systems 1045 – FAST Charge USB (4.8A) Charge your devices faster with our FAST charge USB charger.  It has a whopping 4.8A (total) output, over twice the charge rate of our standard USB charger. Allows the charging of larger devices that need that extra current capacity. This little guy is easy to mount with a 1 1/8″ hole saw, or ask for it to be included in your custom switch panel and we’ll pre-wire it in.  A threaded shank with included nut allows this Fast USB charger to be mounted in very thin dashes up to 1 1/2″ thick. The rubber cap on this USB charger fits surprisingly tight, keeping dust, grime, and moisture out of the USB ports.  It also boasts a conformal coating on the circuit board to protect it from the harsh marine elements; not something found on cheap Chinese generics. With a 9-32Vdc input range, this marine USB charger can be used on 12V or 24V systems.
