CTEK D250SA DUAL DC-DC Charger 12V

Replacing the best-selling D250S is the new D250SA.

This is an intelligent, five-stage battery charger that works in much the same way as CTEK's other chargers. The big difference is that this model is powered from a vehicle's or boat's starter battery so that the domestic / auxiliary batteries are efficiently charged whenever the engine is running. With a continuous output of up to 20 Amps, the effect of this piece of equipment is much faster charging of the domestic / auxiliary batteries and longer life for the batteries too.

Package contains 1 CTEK unit with wired temperature sensor

Now bought three things from Nuke's very own Outdoorbits site - a Kipor gennie, a set of Heosafe locks and a replacement filter for the SOG bog - and all have arrived in perfect condition, by return, with no problems whatsover and at very fair prices.
