FOUR BAY USB BATTERY CHARGER

The NITECORE UM4 is a QC input available intelligent USB four-slot charger with a total max output of 3,000 mA and a single slot max output of 1,500 mA and is capable of charging 4 batteries simultaneously and controlling each slot independently. It only takes 2 hours to charge 80% of a 3,500mAh battery.

The LCD screen can display a real-time information of Battery Health by "Good" or "Poor", Internal Resistance, Charging Current, Battery Voltage, Charged Volume and Charging time. It can enable an automatic detection of battery power level and automatic selection of the appropriate voltage and charging mode and automatic selection between 3 charging modes (CC, CV and -dV/dt). The charging parameters can be set manually to meet various charging needs.

The specially designed Micro USB port is compatible with various mobile power source, solar panel and USB adaptors to ensure endless power supply. UM4 incorporates an optimized IMR battery charging program, which is able to monitor the entire charging process, ensuring that the cut-off voltage is always within safe limits to extend the lifespan of the batteries. The UM4 is compatible with 3.6V/3.7V Li-ion rechargeable batteries, 3.8V Li-ion rechargeable batteries, 1.2V Ni-MH/Ni-Cd rechargeable batteries and 3.2V LiFePO4 batteries.

Multiple safeguards ensure the safe charging process, including automatic battery internal resistance detection, anti-short circuiting and reverse polarity protection, overtime charging protection, over-discharged Li-ion battery activation and over-discharged IMR battery restoration. Apart from being constructed from durable and fire retardant PC materials, the built-in temperature regulation system is designed to prevent the overheat and to ensure the stability of the charging process. If there is no action to the buttons or batteries in 3 minutes, the screen will automatically go dim to save energy.

Reliable but a few glitches

I've been using this for a very long time. Upgraded from the D4.
It's my go to workhorse for a stockpile of NiMh AAs and AAAs.
Generally it's reliable and I am happy with it but it's got a number of glitches:
*If you charge x3 NiMhs, the middle one will always finish twice as fast.
My understanding is, it allocates current in pairs, so an odd number of batteries may allocate double the current to the battery without a pair.
*Which brings into question the authenticity of the displayed current, which shows 500ma for every slot. Then again... the resistance does seem to consistently show half as much for the middle battery. Which could explain ...view more

Great Charger

This thing is a beast. Previously I had a dual charger and have 5 sets of batteries to charge. This would take all day.
Now I charge them in less than half the time. The readouts is comprehensive and shows battery health & charging status among other things.
I would definitely recommend this product!

Much needed upgrade

Needed a new charger, debated between two of them, chose this one. I go through many 18650 batteries a day and being able to charge them all at once is a big bonus. The quick charge input feature with a compatible usb power source makes for fast charging of all cells, each cell has a readout of the time it's been charging, the mAh rating that has been delivered to the cell, the voltage of the cell and it's internal resistance. I might have to buy a second one of these.
