The Nitecore Q4 4-Slot 2A Quick Battery Charger
The Nitecore brand has become synonymous to safe and convenient battery charging. Its line of portable chargers is built with intelligent chips to automatically detect potential risks and ensure maximum efficiency. The blazing fast Nitecore Q4 Charger is capable of producing a 2000mA charging output, and charges 4 slots simultaneously up to 1000mA.
An optimized charging system monitors the entire charging process and ensures voltage is always within safe limits to help extend battery life. And both IMR and Li-ion battery types are supported in multiple sizes like 18650, 18350, 20700, RCR123 and more. During charging, a red LED will illuminate. When completed, a green LED will signal batteries are fully charged. The charger also incorporates reverse polarity, short circuit and overcharging protection to prevent damage to the unit and batteries. If anything unusual is detected, the unit will alert you by blinking red above the corresponding battery slot making the Q4 charger a safe choice for all your charging needs.
Optimized for IMR batteries
IMR batteries are prone to overcharging because of their extremely low internal resistance. This could lead to safety issues when charging IMR batteries on devices that are designed for lithium-ion batteries. To address this problem, Nitecore has optimized the Q4 with a system that is able to monitor the entire charging process to ensure that end voltage is always within safe limits – which ultimately helps extend battery life.
This is why Nitecore chargers are popular among vapers who rely on IMR batteries for their mods and APVs.
The Nitecore Q4 is capable of activating depleted lithium-ion batteries with protective circuit. After inserting the battery, the Q4 will automatically test and activate the battery before charging.
Note: Do not charge over-discharged (zero volt) unprotected lithium-ion batteries.
Charging lithium-ion batteries without protective circuit may cause fire or explosion.
With overtime prevention, the Q4 will individually monitor the elapsed charging time for each battery slot and if a particular slot exceeds 15 hours, the Q4 will automatically stop charging and the green LED indicator will illuminate to indicate completion of the charging process. This feature reduces the risk caused by batteries of lower quality.
Reverse polarity and short circuit protection
The Nitecore Q4 automatically detects reverse polarity. If you insert the battery in the wrong direction, the LED indicator of the corresponding battery terminal will flash red in rapid succession.
If a short circuit occurs, the Q4 will also notify you through a flashing red light.
Quality materials for maximum safety
The Nitecore Q4 is made of fire-retardant, flame-resistant PC material and built to the highest standards of safety. The unit may feel warm during charging but it never gets hot. The chassis is designed with multiple vents for optimal heat dissipation that prevents overheating and ensures a reliable and stable charging process.
Indoor and outdoor use
The Nitecore Q4 is compatible with wall adapters and car chargers so you can charge your batteries whether you are at home or on the road.
