The universal charger Olight UC Magnetic USB Charger is designed for charging cylindrical lithium Li-ion batteries at 3.6 or 3.7 Volts, and nickel-metal hydride Ni-Mh / Ni-Cd batteries at 1.2 Volts, various diameters and lengths.
Universal charger Olight UC Magnetic USB Charger for Li-ion, Ni-Mh, Ni-Cd batteries, features and functionality, overview.
The Olight UC Magnetic USB Charger is lightweight and compact. The body parts of the Olight UC Magnetic USB Charger are made of aluminum. The connecting cables are enclosed in a silicone sheath, the main connecting cable is flat, so when storing the charger is not confused.
Key Features of the Olight UC Magnetic USB Charger.
Operating voltage: 4.7-5.2 Volts
Maximum charging current: 750 mA
Maximum charge voltage: 4.25 V for Li-ion batteries and 1.45 V for Ni-Mh / Ni-Cd batteries
Supported battery types and sizes: Li-ion, IMR, INR, ICR batteries 10340, 10350, 10440, 10500, 12340, 12500, 12650, 13450, 13500, 13650, 14350, 14430, 14500, 14650, 16500, 16340 (RCR123A) , 16650, 17350, 17500, 17650, 17670, 18350, 18490, 18500, 18650, 18700, 20700, 21700, 22500, 22650, 25500, 26500, 26650.

Charge Li-ion and Ni-Mh / Ni-Cd batteries with the Olight UC Magnetic USB Charger.
The Olight UC Magnetic USB Charger will automatically recognize the type and polarity of the Li-ion and Ni-Mh / Ni-Cd battery. All that remains for the user is to attach the terminals of the charger to the battery. They are equipped with built-in magnets, so there will be no problems with contact reliability.
The power of Olight UC comes from any USB port, the voltage in it must be at least 4.1 Volts, and the current at least 400 mA, otherwise Olight UC will not work. For the same reason, it is not advisable to connect this charger to the USB port via additional long USB cables. While charging, the Olight UC heats up a bit while keeping the battery cool.
Charging methods for Li-ion and Ni-Mh / Ni-Cd batteries using Olight UC.
For Li-ion batteries: CC CV
For Ni-Mh / Ni-Cd batteries: CC-DELTA V
In all cases, the manufacturer indicates a constant charging current of 750 mA, but as a result of tests it was found that when charging Ni-Mh / Ni-Cd rechargeable batteries of standard sizes AA and AAA, it is 500 mA. The Olight UC charger is suitable for charging small Li-ion batteries, such as 14500 or 18350. At the beginning of the charge, the current is slightly higher than recommended, but it decreases with increasing voltage.
The charge process is controlled using the built-in LED indicator. The red indicator blinks 3 times per second in standby mode, the red indicator is on, charging is in progress, the green indicator is on, charging is complete. It should be noted that the LED is very dim and its indication is poorly noticeable even not in particularly bright light.
General conclusion about the universal charger Olight UC Magnetic USB Charger.
The Olight UC Magnetic USB Charger is a one-of-a-kind compact universal EDC charger powered by a USB port. It makes it possible to charge batteries almost anytime, anywhere, even on the go. Olight UC can work from a laptop’s USB port, through an adapter from a 220 V household electrical outlet, through USB adapters from a 12-volt cigarette lighter in a car. And in field conditions it can be connected to a portable solar panel or to a powerbank, the main thing is that the capacity of the powerbank be greater than the capacity of the rechargeable battery.
The small size of the universal charger Olight UC Magnetic USB Charger allows you to always have it with you. When minimized, it is not much more compact headphones from a smartphone or MP3 player and can easily fit even in a small bag. And the ability of Olight UC to charge almost all types of Li-ion and Ni-Mh / Ni-Cd batteries makes it a real lifesaver in any unforeseen situation.
