While lights may be an important cornerstone to everyday preparations or emergency situations, maintaining a proper battery source is very important as well. For those that like to have a rechargeable battery source for their lights, Nitecore has introduced a four bay charger that can charge three different types of batteries: the Nitecore i4 Intellicharger. This impressive charger uses a “smart interface” that can identify the battery type (Lithium-ion, NiMH, NiCd) that will choose the appropriate charging method for the battery. Once the batteries are fully charged, the charger will stop charging the battery and can be safely left in its slot until it needs to be used. The charger can be used via a traditional wall plug, or can be charged with an optional car adapter.
