Age Verification

1Account Age Verification

To purchase products from our store, you must be over the age of 18. To ensure you're over the age of 18, we run an effective and monitored age verification process, provided by 1Account. We do not sell age restricted products to persons under the age of 18. By purchasing age restricted products, you hereby consent to the processing of your personal data for age verification purposes.

Why Do We Need To Verify Your Age?

The law in the United Kingdom states that tobacco and nicotine inhalation products cannot be sold to persons under the age of 18. To ensure that we're compliant with the law, we have to carry out some form of age check and we can only do this during the checkout process. Much like buying from a physical location, you would need to provide identification if you looked under age, but because we cannot see who you are, we have to ID everyone.

If you do not verify your age, we cannot legally dispatch your order, so after 5 days (this is when the age verification link expires) we will refund your order, unless requested beforehand.

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.
