Is made of Intellicharger i2 of Sysmax and sold under the brand NiteCore. In addition to the 2-bay charger i2 there with the I4 and the D4 and an 8-slot version also a few big brothers. But the IntelliCharger i4 and the DigiCharger D4 not possess about four charge controllers for its four bays, but only two, the switch back and forth to the rhythm of about 30 seconds between the charging slots are hence only i2 with four shafts or DigiCharger has nor a display. From IntelliCharger i2 stand offered in 2015 two models: The 2014er model has a slide guide made of metal, which is to be slightly shorter and cause problems with extra-long cells can. In addition, the slide guide of metal tilted lighter than the plastic guide (see video). Supposedly to have been carried out conveniently by a higher integration in the 2014er model also electronic components. For buyers view the 2013er Version therefore seems to me to be the better overall choice.
The charging current is always 500mA and can not be adjusted. This is in principle good for 18650, for thin LiIon cells for example for e-cigarettes but this may be too much. About 3 LED the current loading progress and the end of charging is shown. If my measurements, the charging current of 500 mA was observed. However, the battery charger tends to slight charge of the cells up to 4.22 to 4.24 volts. In addition, the charger caused by the built-in 230V power supply has a high thermal load of up to 50.3 ° C the inserted battery cells. Mind you, these are not a self-heating of the cells but by heat radiation from the charger.
Overall, this is the i2 to a very compact charger with built-in 230V power supply, 12 Volt charging way including enclosed car adapter at a very reasonable price. However, the design leads to a high thermal stress on the cells and also the high cut-off voltage is not particularly conducive to a long life of battery cells. For these reasons, I use the i2 only as travel or car charger and I've stepped up a Xtar VP4 as a new main charger. A comparison of both chargers I have loaded onto YouTube.
