Test/review of Charger Nitecore Q2
Charger Nitecore Q2
The charger is a two slot LiIon only charger than can charger with 1A or 2A. It arrived in a cardboard box with a lot of specification on it. The box contained the charger, power supply and instruction sheet. The charger is powered from 12V. The power supply is a standard 12V plug pack. The charger has a LED for each slot and no buttons. The LED will flash red on error, light red when charging and green when done. The specifications are on the bottom of the charger, but very hard to read on the translucent plastic. The charger uses the classic slider construction and will handle batteries from 28mm to 75mm, this will handle even the longest protected cells. The two slots are marked with 1A and 2A, but you have to look careful to see it. The charger can handle up to 75mm long batteries. Some small cells can be charger, but only if they are rated for 1A or more in charge current. Measurements
This is a CC/CV charge curve with 100mA termination In the second slot the charger current is 2A when charging only one battery, termination current stays the same. These cell is handled fine. This old cell is also handled fine. A new high current cell is charged very nicely. With two cell they are both charged at 1A It requires about 1A from 12V M1: 38.5°C, M2: 38.7°C, M3: 48.4°C, HS1: 64.1°C HS1: 57.5°C The charge profile is fairly simple for this charger. The charger starts in about 1 second. The charger power supply passed the 2830 volt and 4242 volt test, this means it is it is fairly safe. Conclusion The charger is a good LiIon charger for larger cells, but can only be used for smaller cells rated for high current charging. As usually with charge current selection by slot I would have liked a better marking on the 2A slot. Notes The charger was supplied by NiteCore for review. Here is an explanation on how I did the above charge curves: How do I test a charger
