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.
DSC_1714
The charger is powered from 12V.
DSC_1709
The power supply is a standard 12V plug pack.
DSC_1715
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


  • Power consumption when idle with no batteries is 0.4 watt
  • Charger will discharge a full LiIon battery with 1.5mA when not powered.
  • When powered a full LiIon will be charger with less than 0.6mA
  • Below 1.9V the charger will not detect a battery, but charger with 2mA
  • Above 1.9V full charge current will be used.
  • Will not restart charging it voltage drops.
  • Will restart charging if battery is inserted or power cycled.

This is a CC/CV charge curve with 100mA termination
Nitecore%20Q2%20%28SA18650-33%29%20%232
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.
Nitecore%20Q2%20%282xSA18650-33%29
With two cell they are both charged at 1A
Nitecore%20Q2%2012V%20%282xSA18650-33%29
It requires about 1A from 12V
Temp5903
M1: 38.5°C, M2: 38.7°C, M3: 48.4°C, HS1: 64.1°C
Temp5904
HS1: 57.5°C
Voltage%20sweep%200-4.25
The charge profile is fairly simple for this charger.
PoweronLiIon
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.
