Efest Slim K2 Charger
Tips for new nicotine users: Sub-ohm or low resistance atomizers produce a higher throat hit than standard/high resistance atomizers. We strongly suggest 3 to 6mg eLiquid or lower with sub-ohm or low resistance atomizer heads. Preference may vary depending on the user and frequency of use.
Use special caution when using Li-Ion cells, they are very sensitive to charging characteristics and may explode or burn if mishandled. Make sure you have enough knowledge of Li-Ion rechargeable batteries in charging, discharging and assembly before use.
Do not let your batteries come into contact with metal objects such as keys, loose change or any other metal objects. Doing so will put you at risk for short circuiting your battery and explosion. Do not put loose batteries in your pocket, purse, bag or anywhere else. When the battery is not in use, you could store it in a plastic battery case to reduce the risk of a battery explosion.
Always charge in or on a fire-proof surface. Never leave charging batteries unattended.
Do not modify batteries or chargers in any shape or form.
Only use Lithium Ion rechargeable batteries in devices that have a built in protection circuit board(PCB) that detect shorts, over-discharge, over-charging etc. Use of lithium ion batteries without a PCB may increase your risk or explosion and/or fire.
Store your batteries away from the sun and heat to prevent overheating your batteries.
Please be sure to inspect your battery before use to ensure it is not damaged including tears / rips in the battery wrap. Discontinue use immediately if battery is damaged.
Do not discharge batteries below 2.5V. Do not charge the batteries over 4.2V.
