The Energy 16 I use for 5 years. I invite so AA (Mignon), AAA (Micro), C (Baby), D (Mono) and 9V block. It offers famous as many batteries like nothing before. Only the V 6988 by Conrad Electronic comes close (10 pieces of AA or AAA - no C, D and 9V, but offers famous slow and recognizes the charging circuit in many batteries do not, so that the batteries are hot). The Energy 16 does uncomplainingly his ministry is ready with any battery, even with what appear in other loading devices to be defective. Despite the perfectly functioning Ladelektronik the operation is very straightforward, friends borrow the device from you and find it great. The unit operates on 100 - 240 V mains voltage, making it usable worldwide, but not in the car at 12 V. A few little things disturb / bothered me on the device: 1) After a few months of operation, the LEDs no longer the same brightness. In daylight, you got the impression that no longer light up darker. I sent requesting repairs and six months later, shows the Ersatzgeraet the same symptom, although it is not every day, but only about 2 days a week. Sent back for repair, the Service has apologized, now I have the third unit and does without problems. 2) The device is quite clunky, poorly take. Due to its round shape a large area is required. And the power cord comes out the back in the center, because you can not even quite the device ranschieben on the wall. Because someone has not thought along. Ansmann will probably stand out by these measures from the mass of square electronic products in my apartment and at the same time leave no room for competing products on the dresser .... Very well. If it is always firmly in place, and if you have enough space, the OK is. As Reisegeraet but it is certainly inappropriate. 3) There is no cover on it. This dust is a charging Scha True. For cooling during charging, it is obviously better without a lid. I place when not in use it a mouse pad. 4) for a switching power supply that is in it, the device is quite warm. Even if no batteries are charged, still lukewarm. Given the Body Size must be wasted in power since quite a bit. On the one hand is that it becomes unnecessary energy consumed and for other age the components thus course. Because if the housing is lukewarm, probably some parts inside the product are quite hot so prematurely dry out capacitors, solders age, etc. After assembly I have the energy 16 but not yet. It special locking screws were used. A power switch is the way, not in it, so you should pull the mains plug when not in use.
Moreover, the device has no quirks. The batteries can be insert well, the power supply generates no noise, the processing is fine, there arise when operating any unpleasant odors, the power cord has an appropriate length, specifications and Quick Start Guide are printed on the component shelf. All of these things are not selbstverstaendlich if you look at competitive products.
Bottom line: A trouble-free battery charger that keeps its promises. Unrivaled by the abundance of batteries which can charge it. The price is reasonable. For minor quirks while not perfect, but so far none and thus a highly recommended product.
