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.

Download PDF The DL10 outputs white light at brightness levels of 385 or 1000 lumens and red light at 55 or 115 lumens. When trying to capture images of nocturnal sea life, the red mode is highly recommended because of the warming effect it produces, which prevents critters from being scared away before you have a chance to photograph them....
Great price, extremely quick processing and shipping our order and the products are great. Non imposing size, easy install and the one we brought for the kitchen does as it says in the blurb - doesn't go off with ever cooking disaster! Very happy
Detectors arrived. Have installed them. I presume they will work okay & last 10 years. Better communication from PSL would have been nice regarding despatch. I was about to email asking where they were after hearing nothing for a number of days after placing my order. Then they turned up with the courier. So, all good.
