The processing of the XC 3000 can hardly be desired. With the metal upper shell is a quality image. The charging bays for standard rechargeable batteries are very good and offer good support and contact for the battery. Only the Unversalaufnahme for LiIon batteries and LiPol convinced not always 100%, as not all batteries will find a steady position. Operation is simple and intuitive to learn. With the battery tester can be as good as all the batteries tested for voltage and remaining capacity. This funtion but I almost do not need. The store is almost foolproof. The unit has reverse polarity protection and fits with LiIon and LiPol the polarity automatically. It can be used for standard batteries two different charging currents set (rapid and early charge). In addition, various programs are possible as refresh, recharge cycles, conservation. It is possible to simultaneously load and any batteries, since the wells are all monitored and controlled individually. What struck me negative is the noise of the fan. He is so loud like a bad PC. He is also not temperature controlled but always goes to when a standard battery is charging (when loading only LiIon and LiPol he stays off). In the very high price of the device that's disappointing. The great advantage of the wide range of applications. But I find it to having to take on vacation as a substitute for all possible chargers like mobile digital camera etc. There is too great.
