The Nitecore UM4 charger is a fast and efficient USB charger that can charge up to four batteries with the option to control each bay independently. The charger has a maximum output of 1500mA in a single slot - please note, this is only achievable if using a 9V 2A QC 2.0 charging adaptor.

The charger features a charging programme specially optimised for IMR batteries which monitors the entire charging process, ensuring that the cut-off voltage is always within safe limits to extend the lifespan of the battery.

The Nitecore UM4 has a useful LCD display which relays real-time charging information. A short press on the 'V' button will cycle through details on the charged volume and charging time, charging current and battery voltage, battery type, cut-off voltage and charging mode. The charger will automatically select from 3 charging modes when the battery is inserted, according to the battery type and capacity. Alternatively, the charging parameters can be set manually to meet various charging needs; long press the 'C' button to enter the charging setting mode.

The charger offers over-discharged IMR battery restoration. When an over-discharged IMR battery is inserted, the screen will show 'EE EE'; simply long press the 'V' button to enter restoration mode. The screen will also display 'EE EE' if a short-circuited battery is inserted or the cell is the wrong way round.

The Nitecore UM4 is compatible with the following IMR/Li-ion/LiFePO4 batteries: 10440, 14500, 14650, 16500, 16340 (RCR123), 16650, 17350, 17500, 17650, 17670, 17700, 18350, 18490, 18500, 18650, 18700, 20700, 21700, 22500, 22650, 25500, 26650, 26700 and the following NiMH/NiCd: AA, AAA, AAAA, C, D.

Regarding Nicotine and Shortfill E Liquids

Many of the E-Liquids for sale on this site contain Nicotine. Any bottle that has 10ml in volume will contain nicotine unless stated otherwise and the nicotine content of these will never exceed 20mg. This is due to the Tobacco Products Directive or TPD for short. 

Those marked for sale with “0mg Nicotine” contain 0% nicotine and are classed as nicotine free. If you want to add Nicotine this can be done by adding nicotine boosters to your e liquid to achieve your desired strength.

A single 10ml nicotine booster that has a nicotine strength of 20mg will turn a 50ml, 0mg nicotine strength e liquid into a 3mg Nicotine strength juice when mixed.

To easily mix your e liquid, we suggest using a 60ml Unicorn Bottle and placing the nicotine shot into this bottle first, then adding in your e liquid, filling the bottle. This is often easier than removing the cap on a lot of the e liquid bottles as some of them are difficult to remove and can cause spillage if not removed with care.

How to make 3 or 6 mg/ml strength shortfill:
Shortfill Bottle + Nicotine Shot(s) = E-Liquid Strength
50 ml + 1 x 18mg nicotine shot = 3 mg/ml
50 ml + 2 x 18 mg nicotine shots = 6 mg/ml
100ml + 2 x 18 mg nicotine shots = 3 mg/ml
100ml + 4 x 18 mg nicotine shots = 6 mg/ml
